4. Show HN: Experiments in AI-generation of crosswords
URL: https://abstractnonsense.com/crosswords.html
Author: abstractbill
Description: Hi HN, I've been experimenting on-and-off over the years trying to automatically generate crosswords [1]. Recently I've been feeling like my results are good enough that I want to share them and see what other people think. I'm not trying to claim that these could appear in, say, the NYT in their current state, but honestly the velocity of progress makes me feel like I will inevitably be able to automatically generate NYT-quality crosswords within just a year or so.
A write-up is here: https://abstractnonsense.com/crosswords.html
And you can play the crosswords here: https://crosswordracing.com (They should work well on both desktop and mobile, and there's a leader-board for each crossword if you want to leave your name when you solve one).
[1]: Just in case anyone is interested, my very first attempt at this problem was way back in 2006! I used multiple wordlists (e.g. list of British monarchs, with reign dates), and wrote little functions to generate clues from each list (e.g. "British monarch who ruled from {date1} to {date2}"). Even with randomized synonym substitution and similar tricks, this approach was too labor-intensive, and the results too robotic, for it to work well. Can't complain though, that project led to me getting hired as the first engineer at Justin.TV!

16. Show HN: Open-source turn detection model for voice AI
URL: #
Author: russ
Description: Hey HN, it’s Russ - cofounder of LiveKit. An open source stack for building realtime AI applications.
We’re sharing our first homegrown AI model for turn detection. Here’s a live demo: https://cerebras.vercel.app/
Voice AI has come a long way in the last year. We now have end-to-end systems that can generate a response to user input in 300-500ms — human level speeds!
As latency reduces, a common problem that surfaces is the LLM responds too quickly. Any time there’s a short pause in a user’s speech, it ends up interrupting them. This is largely due to how voice AI applications perform “turn detection” — that is, figuring out when the user has finished speaking and when the model can run inference and respond.
Pretty much everyone uses a signal processing technique called voice activity detection (VAD). In a nutshell, it figures out when the audio signal switches from speech to silence and then triggers an end of turn once a configurable amount of silence has transpired.
One obvious delta between VAD and how humans do turn detection is we also consider the content of speech (i.e. what someone says). These past few months, we’ve been working on an open weights, content-aware turn detection model for voice AI applications. It was fine-tuned from SmolLM v2 on text, runs on CPU (currently takes 50ms for inference), and uses speech transcriptions as input to predict when a user has completed a thought (also called an “utterance”). Since it was trained on text, notably it works well for pipeline-based architectures (i.e. STT ⇒ LLM ⇒ TTS).
We use this model together with VAD to make better predictions about whether a user is done speaking. Here’s some demos --
- Podcast interview: https://youtu.be/EYDrSSEP0h0
- Ordering food: https://youtu.be/fcr8Y-3c4E0
- Providing shipping address: https://youtu.be/2pQWvd6xozw
- Customer support: https://youtu.be/YoSRg3ORKtQ
In our testing we’ve found:
- 85% reduction in unintentional interruptions
- 3% false positives (where the user is done speaking, but the model thinks they aren’t)
In practice, we still have work to do. We currently delay inference if the model predicts a < 15% chance the user is done speaking. This threshold misses a bunch of middle-of-the-pack probabilities.
Next steps are improving the model accuracy, tuning performance, and expanding to support more languages (only supports English rn). Separately, we’re starting to explore an audio-based model that considers not just what someone says but how they say it, which can be used with natively multimodal models like GPT-4o that directly process and generate audio.

18. Show HN: Callosum – A smarter OpenAPI editor/client
URL: https://callosum.dev
Author: pbnjay
Description: A couple years ago I was really frustrated by Postman, it couldn't do basic JSON schema validation, and didn't interoperate well with the OpenAPI spec I had to use for serverless deployments. On top of that, they started requiring an account and cloud sync, and other things I just wasn't comfortable with.
So what's an engineer to do? Build yet another API Client of course! [0] It's still fairly rough and crashes more often than I like, but it's basically at the point that I've switched most of my usage so I figured I would rip off the bandaid and do a Show HN.
Short list of some of the (IMHO) cool features that you can't do in Postman:
* Generate JSON Schema from request/response data.
* Generate request content template from JSON Schema.
* Reusable Schema components (Analyze->Extract Schemas menu)
* Basic field and JSON validation (so much more to do here!)
* Embeddable environment and encrypted variables [1] in the OpenAPI document.
* From scratch, run a MITM proxy and record API requests, then automatically generate an OpenAPI spec.
* Deep linking w/o a web server.
There's a short youtube playlist of some of these features, but I need to spend some time demoing the rest of them. What is most interesting to folks?
I would love to integrate better with the API doc generation tools but need to figure out how that would look. Speakeasy/Redocly/etc are some great projects and I don't want to reinvent the wheels there.
I would also seriously appreciate some tough love/feedback to make this even better. I'm sure someone smarter than me can pick apart the variable encryption (I broke rule #1 of cryptography and rolled my own, but I couldn't find a similar use case)

Author: sahillavingia
Description: Shortest is an open-source AI-powered testing framework that allows developers to write end-to-end tests in plain English, as simple as:
shortest(“user can sign up and create a $5 product”)
The thesis is that being able to write short tests in English → more tests → fewer regressions as AI writes and ships more code.

21. Show HN: rtrvr.ai – AI Web Agent for Automating Workflows and Data Extraction
URL: https://chromewebstore.google.com/detail/rtrvrai/jldogdgepmcedfdhgnmclgemehfhpomg
Author: arjunchint
Description: Hey HN,
I'm excited to share rtrvr.ai, a Chrome extension that brings the power of AI agents to your everyday web browsing. It's designed to automate complex web tasks, extract structured data from any website, and integrate with your favorite tools as you browse using AI Function Calling [ie: “Send this page summary as Slack message”].
The core idea is to let anyone, even non-developers, leverage the power of web automation and data extraction using natural language. Imagine being able to:
Automate lead generation: Extract hundreds of LinkedIn profiles to Google Sheets, complete with AI-generated, personalized intro emails.
Process PDFs in bulk: Pull data like revenue, expenses, and totals from hundreds of local or online PDFs directly into your spreadsheets.
Navigate and extract from paginated lists: Tell rtrvr.ai, "For each YC Partner, go to their LinkedIn profile and retrieve their name, headline, job, and college," and it'll do it.
Automate workflows across multiple tabs: For example, fill out job applications on Careers tab using information from the LinkedIn tab.
Function Calling: Integrate with APIs like Snowflake and Slack directly from your prompts using simple @ notation or letting the AI infer what tool to use with natural language.
GraphBot: Generate charts and visualizations from website data with natural language commands.
Recordings: Ground the agent with site interactions recordings to ensure accurate and repeatable task execution.
Sheet Context: Use Google Sheets data as context for your web tasks.
Scheduling: Run automations on a schedule in the background.
Sheets Workflow: You can feed a Google Sheet with a column of URLs (like LinkedIn profiles), and it will open each url as a tab, extract data, and even generate content (like intro emails) back into the sheet. It can handle multi-step workflows with prior output dependencies, effectively representing a DAG.
I see rtrvr.ai as a step towards a more intelligent and interactive web. I believe this tool can be a game-changer for marketers, sales professionals, SMBs, and anyone who needs to extract information from the web efficiently. Would love to hear your feedback, suggestions, and any use cases you can think of!

Author: popoxdev
Description: I have been building a lot of side projects alongside my studies and I often found myself needing a quick way to record and share demos of my apps. After trying out some of the most popular screen recorders, I didn't find any that met my needs. I wanted a tool to quickly record high-quality product demos without downloading multiple pieces of software. So I decided to take on the challenge and build a simple yet powerful screen recorder extension that allows you to record directly from your browser. It has a few key features such as smooth animated cursor, zoom effects, shortcuts hints and much more that I plan to add.
It's my first time launching a product to production so any feedback is greatly appreciated! I have also created a spreadsheet where I compared my tool with popular screen recorders if you want to learn more: https://screendemos.com/comparison

31. Show HN: Build, test, and deploy your own LLM router
URL: https://platform.mintii.ai/login
Author: martinpmm
Description: We created an LLM router to improve quality and reduce costs for LLM applications.
We started this project some time ago and used the router internally due to our own experience developing LLM solutions. We realized that there were many challenges when working on projects with LLMs:
First, the quality of the model. Every week, new models are released with improved capabilities, so the projects we built months ago become somewhat obsolete (and changing the model can be a pain).
Second, costs. As we scaled the solutions, we realized that cost is a limiting factor for real use cases. Also, every 3 months, there are drastic changes in prices, so many ongoing LLM solutions today are probably paying more than they need to.
Third, why should we use only one model? Using a multi-model approach offers a much better opportunity to get the best out of every model, reduce costs, and more.
With that in mind, we started mapping models to their best performance in tasks (like coding, creative writing, etc.) and also mapping them by topics (Finance, Tech, Marketing, etc.). We included other factors like cost and latency to create our optimal solution.
Today, the research we conducted became what is now the first version of our router, which redirects prompts to the model selected by the user based on the difficulty of each prompt.
Try it out and let us know what you think! You can create a custom router, test it in the chat interface, and later, once you have some conversations, create evaluations to compare the router’s performance with a single-model approach.
This is the first version of the project! We have tons of other ideas/prototypes that we are adding to the platform in the short term (new types of routers, automatic model selection based on sample prompts, model usage suggestions, calibration metrics, and more).
We are keen to receive feedback from the community.

Description: I've been learning about Sikhism and Sikh history recently and, despite having Game of Thrones level drama, I found the resources really lacking and nowhere piecing it all together.
I work in a developer adjacent role (ok, I'm a Product Manager) but despite working with software engineers every day I don't really get coding. I see a lot of stuff online about the death of software engineers and wanted to challenge myself to see if I could create something myself.
I've been using the free tier of Anthropic's Claude AI, deployed on the free Vercel tier, spent $10 on the domain but not a penny more on anything else.
It's super basic but felt good to make something myself and I learned a lot. I'd brick it at the idea of adding anything complex (or even being asked how it all works together) so I'm sure developers are safe for a while yet!

Author: lbeurerkellner
Description: Our team at Invariant has built an awesome agent testing challenge for the holidays, that showcases how agent development can benefit from concepts known from test-driven software engineering.
You can play the challenge at the linked URL. You are given a pre-existing agent implementation where you can only change the system prompt and your goal is to make a small test suite of unit tests pass. The tool implementations are complete, but the agent needs to be instructed to use them properly.
The challenge was created to showcase two open source projects we released recently: A trace viewer for agent trajectories (Explorer, https://github.com/invariantlabs-ai/explorer) and a library for building agent unit tests (Testing, https://github.com/invariantlabs-ai/invariant).
Let us know what you think, we'll be around in the comment section. Happy holidays everyone!

52. Show HN: Testing career aptitude by measuring what information 'sticks'
URL: https://www.anewaptitude.com
Author: imfinn
Description: I built a platform that measures career aptitude through an unconventional approach: presenting technical scenarios from different professions and analyzing information retention patterns.
Here's an example from the job resonance test for Forensic Science Technician (there are 100 jobs currently available):
------------------------------------
Natalie, Forensic Science Technician
A crime scene investigation involves recovering trace evidence that could help solve a burglary case. Natalie is utilizing an electrostatic dust print lifter to capture footwear impressions left on the floor. At this time, she is carefully applying the film to ensure even contact with the surface, preserving the impression for analysis in the lab. This procedure aids in establishing the presence and movement of individuals at the scene of the crime. Story 1 of 15
And the question (for this story) asked after all the stories are presented:
How does using an electrostatic dust print lifter assist in a burglary investigation?
A. Preserving footwear impressions for lab analysis to show the movement of individuals.
B. Cleaning the floor of the crime scene to enhance the appearance for photographs.
C. Ensuring all evidence is well-preserved by using advanced surface-cleaning techniques.
D. Identifying the type of flooring material used by analyzing the impression depth.
------------------------------------
Rather than relying on self-reported preferences or personality traits, the system exposes users to authentic professional scenarios (including industry-specific terminology and processes), then tests which details naturally persist in memory.
The core insight: our brains tend to better retain information that aligns with our natural aptitudes, even on first exposure. By analyzing these retention patterns across various professional domains, we can identify potential career fits that traditional assessments might miss.

Curious to hear HN's thoughts on using cognitive retention as a signal for aptitude measurement.

Author: Renesat
Description: I have been thinking for a long time how to solve the problem of publishing my nix config, but without revealing some information (like mail). I thought of something like an external closed subrepository or git-crypt. I wondered if it could be done in a more “nix way”, but had no idea how. After discovering oddlama's blog post "Evaluation time secrets in Nix: Importing encrypted nix files" [1], I realized that nix plugins would be a good fit for me. I just wanted something more “robust” and decided to dive deeper into nix plugins and try to implement it myself on rust. Mostly for my own config, but I think this project could be useful to someone else.

54. Show HN: A faster and compliant way to scrape the SEC
URL: https://github.com/john-friedman/datamule-python
Author: jgfriedman1999
Description: The SEC rate limits you to 5 requests per second. The SEC has more than 16 million submissions, with each submission having multiple documents. For example, Tesla's 2021 10-K SEC page has 14 documents.
Scraping every SEC submission document by document would take about 200 days.
There is a faster approach. Submissions to the SEC are stored in Standard Generalized Markup Language in one file. That means that if you have a SGML parser, you only have to download the submission .txt file. Scraping every SEC SGML submission takes about 40 days.
There is a much faster approach. SEC data is stored in SGML in daily archives accessible here going back to 1994: https://www.sec.gov/Archives/edgar/Feed/1995/. Since the SEC rate limits you to 30mb/s of egress and there is 3tb of data, downloading every archive takes slightly more than a day.
I've written a fast SGML parser here using Cython: https://github.com/john-friedman/datamule-python

URL: https://www.auxilia-tech.com/blogs/pydicos

Description: DICOS is an "Open Standard" for security body scanners, CT or standard X-ray scanners. It is meant to be an inter-operability standard, designed by NEMA and promoted by TSA (https://www.tsa.gov/for-industry/open-architecture), heavily inspired by DICOM.
However there currently aren't any open source implementation of DICOS : you have to contact TSA to get access to binaries of a DICOS developper toolkit. As a further hurdle, big brands of security scanners lobby hard against this standard and opening themselves up to competition.
As the CTO of a 3rd-party algorithm provider for scanners, I believe the "Open Architecture" approach is the future for airports. We are releasing the pyDICOS library to make it more accessible and hoping that people make the most out of it around the world, and making it standard everywhere.

Description: I built a website which lists all hackathon posting from various other sources (currently Devpost and Unstop), on click it redirects to the original source.
Surprisingly, the APIs these websites used were open, which they used to populate their page with hackathons data.
So by spending maybe around 3 hours? This is the end result. It is built using Nextjs 15.
I tried to make it as best as I can, but hey, would love to hear any comments on improvements. There maybe some mistakes but yeah, I am here to learn.
Also, not the greatest of the UIs, but I wanted to get out the MVP, while most of my time was spent in normalizing the JSON from different hackathon website APIs.
I am looking to add more sources, eg. devpost, hackerearth, hack2skill, etc. I might need to scrape their data as their HTML is prepopulated when it is fetched, or have to find some other turnarounds.

67. Show HN: Adding Python Plugin support to my AI app Llama Run to automate your PC
URL: https://apps.microsoft.com/detail/9nw950zx02cq?hl=en-US&gl=US
Author: KrishBaidya
Description: I wanted to share a project I’ve been working on—an assistant app called Llama Run. I initially built it to do simple tasks on my PC (change settings, perform automation, etc.), but as the project evolved, I became interested in making it extensible with Python Plugin support.
Here's the backstory: While researching automation libraries, I came across PyAutoGUI, which allows you to control your PC through Python (moving the mouse, typing, clicking, etc.). It got me thinking about the potential of combining Python's flexibility with event-driven automation inside my app. Later, I found a GitHub repo that combined PyAutoGUI and OpenAI API for automation—this inspired me to give users the ability to create and run custom Python scripts directly in Llama Run.
How it works: I’m integrating Python through the CPython API alongside C++, allowing the app to run Python scripts dynamically. The plugin system will allow users to write Python code to interact with the app and automate their own workflows. By using a plugin system, I’m also keeping the app's core logic separate from custom user functionalities. I’m still developing this feature, but I’d love feedback or suggestions from the HN community. I’m eager to discuss the process and gather ideas on how to make this even better. In the meantime, if you're interested, here’s the Microsoft Store link: [https://apps.microsoft.com/detail/9NW950ZX02CQ?hl=en-us&gl=I...] (This doesn't include the plugin system).

68. Show HN: Eszett explicit scopes for styling react components
URL: https://github.com/errnesto/eszett
Author: errnesto
Description: Hello HN :-) I built "eszett" a small plugin to help manage scoped CSS in React, especially with server components in mind. It’s heavily inspired by styled-jsx. It always bugged my that I can not access the class names, that styled-jsx generates, in my code.
So the core idea is simple: eszett generates a unique class name for each component (like styled-jsx) but then lets you access those class names and you have to scope your styles manually.
I thought giving access to the class names is all I need for a complete plugin, but using it I really missed the automatic rewriting of the class names, so I added that. Maybe at a later stage I will also update this to rewrite the css too.
I built this with swc just to get a chance to play around with rust. This still needs a lot more tests, and also I would like for it to be compatibe with more than just the latest nextjs. But I’d love to get some feedback on how it could be improved and if this concept only makes sense to me or also to others :-)

69. Show HN: ChameleoCV – Tailored CV and Cover Letter Generator with OpenAI
URL: #
Author: Mertugrul
Description: What it is: ChameleoCV is an intelligent application designed to revolutionize the job application process. By leveraging the power of the OpenAI API, ChameleoCV streamlines the creation of professional and personalized resumes and cover letters tailored to specific job descriptions.
Why I created it: As a software developer with over 5 years of experience, I recently re-entered the job market after taking a break. Over the past few months, I’ve found that securing the roles I want has been challenging. While using ChatGPT to create cover letters for different job descriptions has been helpful, I realized that tailoring both the CV and cover letter for specific job positions significantly increases the chances of landing interviews.
However, applying to over 20 positions a week makes tailoring each application manually a time-consuming process. To solve this, I developed ChameleoCV, an application that takes your general CV and a given job description to automatically generate a new, tailored CV and cover letter for each specific role—saving an enormous amount of time.
How it works: With your CV provided in JSON format and a job description as input, ChameleoCV creates a tailored prompt for the ChatGPT API. It then calls the API to generate a customized CV and cover letter, which are returned in PDF format for immediate use.
GitHub Repository: ChameleoCV on GitHub: https://github.com/mertyertugrul/ChameleoCV
I’d greatly appreciate your feedback and constructive code reviews. Let me know how I can improve this project or add features that would make it even more helpful!

70. Show HN: Unify Browser – WebKit Browser Built with SwiftUI and MLX
URL: https://apps.apple.com/us/app/unify-ai-browser/id6478436147?mt=12
Author: quicheshore
Description: Hi everyone! Unify is a WebKit based browser with an AI research assistant built right in. You heard that right. No chromium here.
The project started out as a simple RAG engine to answer queries, but it evolved to become much more in a short period of time. The goal is simple: find the best context, without prompting input, to best answer your questions. One of the biggest limitations of apps like ChatGPT is their lack of personalization. Beyond the chat window, your conversations with the model don’t contribute much to its understanding of your personal context. Every session starts from scratch, as if the model has a blank slate. This isn’t how humans work, and Unify is designed to bridge that gap.
Unify indexes any file format, allowing you to simply drag and drop files from your computer to make them part of your conversational context. The next time you have a question, your conversations from the past, with your files, now have the possibility to aid in answering questions that are personal to you. You can query across thousands of documents without worrying about token limits, lost context, or prompt engineering. LLMs shine when they have enough context to produce insightful, non-generic answers. Unify makes that possible.
So why is it a browser? In some ways using the term “Browser” makes Unify a trojan horse product. But the most important source of them all is the internet. It is the gateway to all information. Just like with files on your computer, Unify will also index any website with just a click. No more copy-pasting text into a chat window, hoping you’ve captured the right context. By integrating both web content and personal files into a single stream, Unify helps eliminate workflow fragmentation and streamlines the search process.
Unify also offers local inference using the MLX framework. Powered by Llama 3.2-4b, it allows you to take your conversations private when needed. While larger online models are still better for generating the best answers, Unify gives you the flexibility to switch to secure, offline, and private inference without sacrificing functionality.
Full disclaimer, I am a solo developer working on this. I would love any and all feedback I can get on this. Please let me know how I’m doing!
You can get Unify on the Mac App store. Check it out here: https://apps.apple.com/us/app/unify-ai-browser/id6478436147?...

Background: I used to use Photoshop to resize images without cropping and optimized them that way. But there is no way to do this programmatically, so I got tired.
Zapier also doesn't have great tools for it, and the only one that is there is f*ed and doesn't work for me.
