8. Show HN: Karl – A virtual friend you can text
URL: #
Author: cheeseblubber
Description: Hi HN! We’re excited to introduce “Karl” – a virtual friend you can text to share what’s on your mind.
We created Karl because we found it incredibly helpful to have a sounding board and someone I could talk to anytime, day or night.
Karl isn’t meant to replace real friendships but rather to act as a mediator and an additional point of contact. He remembers important details you share and can connect the dots between past events and current decisions.
Anyone can message Karl by texting +1 (844) 619-7958 . There’s no separate app or website – just text to start a conversation. The first ten messages are free, after which Karl charges 10 per month to continue (and to help cover Karl’s dining habits).
On the backend, we primarily use 4o (OpenAI) to handle message flow and identify important memories. All the code for LLM calls, context management, and tool use is custom-built, as we found frameworks like Langchain to be too much overhead.
Moving forward, we plan to run a fine-tuned 4o-mini model and experiment with other providers. Texting is powered by Twilio (and FYI – getting a non-sandbox phone number is quite a process), and we use Postgres (via Supabase) to store conversations and context. The entire service runs on Render.
We’re also working on new features like proactive check-ins and smarter memory handling.
Karl is currently in early alpha. We’d love feedback from the HN community at [email protected]. Please say hi, and we hope you have some great conversations!

11. Show HN: Satoshi9000 analog BTC key generator (mechanical)
URL: #
Author: AJTSheppard
Description: I built this machine so I could generate Bitcoin keys that I could trust. Air-gapped and simple to use and understand (mechanical).
The Satoshi 9000 demo: https://youtu.be/bJiOia5PoGE
The key value proposition of the machine is that it generates analog randomness in the physical world and converts it into digital (1’s and 0’s) randomness. Seamlessly.
But it occurs to me that it may have other uses beyond crypto keys for your own use, such as:
- Randomized clinical trials. Clinical trials need a high degree of transparency for ethical reasons; also, for legal reasons should it come to light after the trial has ended that patient selection and treatment selection was not random or in some way biased (say, by the researchers themselves). The machine described herein can provide that transparency to young and old patients, technical and non- technical.
- Non-technical management. Many network engineers in need of security keys have bosses that are non-technical. Such managers might prefer security keys (and their generation) which are easier for them to understand.
- Estate planning. Suppose members of a family were to inherit digital assets (such as Bitcoin, for example). Not all members of the family are technical and understand Bitcoin. However, each will still need to generate a secure Bitcoin key to receive their share of the inheritance. The machine described herein might help in that task because its source of randomness is more easily understood by laypeople and each can generate their own private key in private (in isolation with the machine).
- Anywhere where the users have to have an intuitive understanding of how the randomness is being created; whether they are 5 years old, or 95 years old, and all ages in between.
I’m curious to know if any of the folks over at HN can think of other use cases?

16. Show HN: 2KB JavaScript Dependency Injection Library Without Decorators
URL: https://github.com/ivandotv/pumpit
Author: ikins
Description: Hi HN,
I’ve created a lightweight dependency injection (DI) library for Node.js, weighing in at under 2KB gzipped. It’s perfect for both backend and frontend projects where size is critical.
A few things that I believe set this library apart:
No Decorators: Unlike many DI libraries, this library doesn’t rely on decorators. This makes it cleaner and more compatible with different JavaScript environments, especially for those who prefer not to use decorators.
Tiny Footprint: At less than 2KB gzipped, it’s a great choice even for frontend applications where bundle size matters.
Minimalist API: Simple and intuitive, it doesn’t add unnecessary complexity.
I created PumpIt to fill a gap between heavy DI frameworks and minimalistic, easy-to-use solutions.
I’d love to hear your feedback or suggestions on how it could be improved.

Description: Looking for some feedback on this new tool I’ve developed that gives you detailed grammar/vocabulary explanations of song lyrics in different languages, for language learning purposes. Romanization is a known issue that I’m working on (in cases where the lyrics are available only in romanized form, it’s difficult to convert them back to the original script). Other than that, all comments/suggestions are appreciated!

URL: https://www.youtube.com/watch?v=ku20aJMgyAU
Author: giolekva
Description: Hey everyone, I want to share my open-source project I’ve been actively working on for the past half year. It is a PaaS solution and can help you both during development process and in running your applications in production. It is fully self-hostable and comes with bootstrapping tools, which takes IP addresses of your Linux servers and installs its own fault-tolerant cluster on top of them.
I just recorded a screencast demonstrating its capabilities such as: cloud based dev environment, provisioning relational databases and securing applications with dodo authentication services. It also comes with built-in mesh VPN solution, is opinionated about authentication and implements group based membership service.
dodo provides high level and easy to use primitives, and I tried really hard not to leak low level infrastructure details. I think I achieved that. If you watch the video, the only place where you can get some idea of what internal details look like is when you see the word Ingress, but hey it is a general term :) You can think of dodo as glue tying lots of already existing open-source solutions and having relatively strong opinions about it.
I’ll be active here to answer your questions, but you can also reach me via email at giolekva [at] gmail [dot] com or on Matrix at @gio:v1.dodo.cloud

26. Show HN: Semantic search engine for finding relevant VCs and angels
URL: https://graph.one/investor-search
Author: macieklaskus
Description: We built a search engine that matches startup descriptions with investors based on their historical investments. Write your startup description and get a list of investors who’ve backed similar companies.
Technical implementation:
- Indexed 9k active VC funds and ~5k angels globally
- Fine-tuned a custom embedding model on real-world pairs of investors and companies
- Developed an identity resolution system to collate portfolio data across many sources including portfolio websites scraped with a custom AI agent
Key features:
- Search full investor database without signing up
- Optional email/calendar integration shows 1st/2nd degree connections to investors
- Results ranked by semantic similarity to historical investments
Example query: “B2B SaaS platform for automating accounts payable workflows using OCR and ML” → Returns VCs/angels who’ve invested in similar enterprise automation/fintech companies
Origin: Built this after struggling with my own seed round. Existing solutions didn’t solve the core problem: systematically finding ALL relevant investors, not just the obvious ones.
Would appreciate feedback on:
1. Search result quality/relevance
2. Additional data points that would be useful
3. Performance/latency issues if you encounter any

URL: https://ltmeyer.github.io/2024/10/15/online_data_generation.html
Author: LTMeyer
Description: Hey, I’ve been designing a framework to improve the training of deep learning models on expensive numerical simulations. Instead of relying on limited, pre-generated dataset, the approach streams data directly from large-scale numerical simulations running simultaneously with training. Because it avoids I/O bottlenecks it makes training faster and cheaper.
It is implemented as an asynchronous iterable dataset using ZMQ for data communication. I would love your thoughts on how to extend this to a full-fledged event-driven application.
Although the framework target cluster environments, the link contains code you can try locally. Check it out and let me know what you think!

Author: riqwan
Description: Victor & I (Riqwan) built this starter as a way to showcase how you can build B2B stores on Medusa 2.0.
We’re both developers at Medusa (an open source commerce platform) and we’ve launched our 2.0 version today after a year of working on a more modular commerce architecture.
We built our own workflow engine to perform actions on multiple modules with the ability to revert each step incase a failure occurs at some point in the lifecycle. Modules are encapsulated group of related logic - like product management, fulfillment, orders, promotions, etc.
We’ve also built our own query engine based on GraphQL that you can use to query across modules or even external services - like Sanity or other CMS. Tinloof did a very cool demo of this earlier today.
The whole point of our 1 year work was to make things easily customizable and be able to easily work with the plethora of external services every commerce company would have to work with.
It takes less than a minute to get started locally. Give this a shot and let us know if you’ve got any feedback.

URL: #
Author: alooPotato
Description: I was inspired by the notification summaries on iOS 18 and really liked the idea of AI giving you a quick preview of the content before going to the content. I applied that to HN and built a Chrome extension that summarizes the sentiment and content of HN comments and previews it right next to the stories on the homepage. Makes it so much easier to decide whether I want to delve into the HN comments of a story.
It gave me a chance to play with Gemini 1.5 Flash-8B which has been great. Super fast, super cheap, huge context and does a great john on basic tasks like summarizing comment threads.
Get it here: https://github.com/StreakYC/hn-summarizer/
You’ll also need a Gemini API key from: https://aistudio.google.com/ to make the extension work.

URL: https://github.com/srcbookdev/srcbook/blob/main/README.md
Author: nichochar
Description: Today we’re releasing a full AI app builder in Srcbook. We released our TypeScript notebook a few months ago (https://news.ycombinator.com/item?id=41291700) and the response was encouraging, but we kept hearing that people wanted to build interactive apps.
Today we are releasing just that. You can think of it as an open-source and local version of vercel’s v0. We actually think of it as something in between an IDE and that, because we believe the code matters and don’t shy away from that: you can view and edit the code in a full editor, but prompt your way forward if that’s what you prefer. When the AI makes changes you can review the files diff like you would a GitHub pull request, and toggle between versions to view the visual diff.
Try it now: npx srcbook@latest start
It’s surprisingly good at building apps, especially with the latest claude model sonnet3.5 that came out yesterday. Here’s a video showing building and iterating on a ticket tracker MVP in a few minutes https://www.youtube.com/watch?v=jYOmzasvP74
Key features:
- bring you own API key
- diff viewer
- apply/undo mechanism to see the visual diff
- export the code
- code is OSS under apache2

URL: https://ttshift.com
Author: apel
Description: I want to create a work schedule builder that is (1) easy to start with and (2) offers great flexibility. And now I have a very basic MVP that I want to show.
Here are some things it can handle while building your schedule:
- Set the number of workers needed per shift and specify constraints. Ex: each shift has a minimum of 8 workers and 2 of them must be certified staff that can be assigned to hazardous tasks.
- Respecting mutually exclusive shifts. Ex: If the worker is assigned to a night shift, he can not be assigned for a day shift on the same or following day.
- Take into account each worker’s availability and the maximum number of shifts they can work. Ex: John is only available on weekdays, and can do 3 shifts per week.
- Enforce mutually and non-mutually exclusive constraints. Ex: if the worker is assigned to handle the cash register during the morning shift, he cannot also be assigned as a floor supervisor during that same shift, since both roles require full attention.
- Prioritize certain constraints over others to ensure critical tasks are covered, even if not all shifts are fully staffed. Ex: In the event of understaffing, prioritize essential roles like healthcare or safety positions.
- Takes into account workers’ preferences regarding who they work with or who they prefer to avoid. Ex: Sophie, Emma, and Noah have a great rapport and boost productivity when scheduled together so consider this when building the shift.
If you want to try it, keep in mind that it’s just an MVP to play around with. Sometimes you’ll have to be extra verbose with your requirements to get the desired result.
I really appreciate your feedback.

58. Show HN: Made JavaScript’s compare-and-set to make other sync primitives with it
URL: https://github.com/omranjamal/synchronization-atom
Author: omranjamal
Description: I have recently pick up a bad habit of writing JS like I write Go. As such, I end up imagining in my head that async calls are just goroutines and that I need to sometimes do messaging or synchronization between them.
Ended up being kinda sad that JS ecosystem’s thread syncing libraries are kinda hit or miss and kinda patchy. The “idiomatic” javascript libraries that implement locks don’t lend themselves too well to all the other fancy sync primitives from the Python or Java ecosystem.
So I created synchronization-atom, the “compare-and-set” of the JavaScript world.
It can 1: match a condition and apply an update to the condition as one atomic operation, or 2: have “threads” waiting for a condition to match before they unblock (via async await).
I had to implement both a Promise API and a callback API as Promises effective resolve on next tick, leaving some race conditions open. The callback API does not suffer from the same next-tick issue and are synchronous.
The README has example of implementing a few of the common sync primitives, with more to be documented soon (like channels or re-entrant locks).

61. Show HN: SQLify – Query all your apps and APIs using SQL
URL: https://sqlify.me
Author: emixam
Description: Hello HN,
We are happy to announce SQLify, a new product from the team behind Kantree (https://kantree.io).
Some time ago, we had the request to access data from Kantree through BI tools. We realized one of the easiest way to achieve this was to provide an SQL interface, compatible with PostgreSQL, so that data analyst could query Kantree data like they’re used to. No need to learn the details of our API.
We realized this process could be useful for many other uses cases. SQLify was born !
It is a superset of SQL that allows you to query APIs. We provide integrations with popular tools to easily query them. It feels like all your data is accessible inside a single database. No more complicated ETL pipelines our synchronization processes.
It becomes really easy for smaller teams to do data analysis. Imagine joining data from stripe, airtable, some internal databases, etc…
SQLify is compatible with the PostgreSQL protocol and so can be used through thousands of existing solutions.
This is a BETA product. We are still actively developing it and there are many limitations at the moment. But we believe there’s a lot of potential using this novel approach.
Let us know what you think of it, we are excisted to gather feedback !
