3. Show HN: Langur – consistent, observable LLM agents
URL: https://github.com/anerli/langur
Author: anerli
Description: Hi HN! I’ve been working on a new type of LLM agent framework designed with consistency and observability in mind. The agent behavior is represented as a directed graph, you can save/load agents, and the agent representation is JSON so you can store agents or send over the wire. It’s also designed to have modular behavior that can be customized, and makes it easy to connect to real-world systems.
Would love to hear anyone’s thoughts!

4. Show HN: I built Timelogga so I can generate accurate timesheets quickly
Author: mazahermuraj
Description: I’ve been building and shipping products for nearly 10 years now. But not for me. For my employers. So I tried freelancing, to get started for myself.
The pain point when it came to freelancing wasn’t finding gigs. Thankfully, I found many, and many found me.
The REAL pain point was creating a timesheet reflecting the hours I had put in so I could be paid for my time.
I initially used tools like Google Sheets but it was too manual. And I found similar products online which were either limited or expensive.
So I built my own tool, Timelogga.
Now I simply:
- Click play when I start my task
- Do what I need to do
- Click stop
…and I have the makings of a timesheet.
I can generate my timesheet whenever I want. Not just for one client, but as many as I want.
Click on the link, and scroll to the interactive demo to try it out. I’d love your feedback
Thank you!

6. Show HN: Simtown.ai – US Election Simulation with AI Characters
Author: syzmony
Description: Show HN: simtown.ai – US Election Simulation with AI Characters
Inspired by the Generative Agents paper [0], we’ve created a browser-based simulation of the upcoming U.S. election with GPT-driven versions of Kamala and Trump, along with nine diverse NPCs representing voters in Pennsylvania.
These AI characters freely roam, interact with each other, and engage with real players. Currently, we have a single global instance where everyone can interact together. Single game-day is 24mins in real life.
What can you do?
- Listen to speeches by the candidates
- Chat with NPCs and other players
- Persuade others to vote for your candidate
- Eavesdrop on conversations between other players by moving closer to them
- Explore the environment
- Observe the final vote tally once everyone make their mind
We appreciate any feedback or suggestions!

8. Show HN: Colorful Images with Uniform Grayscale Values
URL: https://github.com/zainhussaini/uniform-grayscale-image
Author: zainhussaini
Description: Normally, when you convert a color image to grayscale, you can still recognize the image. But what if you could keep the image’s color while making it convert to a uniform gray?
This project explores an algorithm that takes an RGB image and adjusts it so that it appears visually similar in color but turns into a single shade when converted to grayscale. The method uses color-space math to preserve hue while adjusting brightness and saturation, resulting in unique images with hidden uniformity. It touches on color theory, the RGB and HSV color spaces, and some linear algebra. Check out the code and math behind this experiment!

11. Show HN: Make Animated Kamala/Trump Toons with AI Lip-Sync for Election Day Fun
URL: http://blabberize.com/easystart
Author: wavewash
Description: We made an in browser animation tool that’s simple but requires users to understand keyframe and timelines. Because there was a level of education as a barrier to the application we though it’d be fun to have a wizard create something of value that then is loaded into the animation tool as a starter project.
The wizard tool we created is at the link. You give a few sentances and we used a voice clone model to produce the text to speech audio which is then filtered into our lip-sync model and applied to a template scene that we have.
When you get dropped in to the animation tool - you’re given 12 free seconds of processing time. If any of you end up with animation that goes beyond that, shoot me an email and I can load your account with more credits or if you want to purchase your credits use code DEBATE and it’ll take 30% off right away.

12. Show HN: A communally-constructed digital archive and ode to long-distance love
URL: https://notes-from-afar.onrender.com/
Author: clarionsong
Description: Just deployed my first webapp! A https://www.queeringthemap.com/ -inspired digital archive + mapping site where you can leave anonymous notes about people you love who are far away from you.
Some other features:
- when you make a note, you can send a secret link to your friend for them to reply
- when you make a pin, it gives you a secret friend code you can share with others for them to write to your “inbox”
- pins are stored locally on the browser but you can get an editor link for each pin — if you open this link in another browser it provides that browser edit access to that pin
(it might be a little slow since i’m currently not paying for a very expensive server)

13. Show HN: Turn Scripture Memory into a Fun, Daily Game
URL: https://www.hidetheword.app/
Author: vaneyckseme
Description: Hey HN! I’m thrilled to share *[HideTheWord.app](https://hidetheword.app)</a>, an app I built to tackle a challenge that’s been close to my heart: creating a consistent, impactful routine for scripture memory.
### Why I Built HideTheWord
For years, I struggled with staying consistent in memorizing Bible verses, often forgetting the ones I’d learned or feeling lost on what to memorize next. HideTheWord was born out of my journey to cultivate a deeper, more intentional approach to scripture memory.
### What HideTheWord Offers
1. A Library of Verses
HideTheWord keeps track of all your verses, whether you’re currently working on them or they’re already memorized. This feature has been invaluable for me to see, at a glance, what’s in my heart and what I’m working toward.
2. Verse Suggestions When You’re Stuck
Sometimes, I don’t know what verse to memorize next, so I added a feature that offers verse suggestions tailored to my needs. Now I have a reliable “next step” every time I want to deepen my knowledge.
3. Personalized Micro-Lessons
I wanted a way to interact with the verses daily without feeling overwhelmed, so HideTheWord generates bite-sized lessons each day. These lessons come in three formats:
- Read and Reflect: A moment to read and jot down reflections.
- Fill the Blank: Test recall by filling in missing words—great for sharpening my memory.
- Multiple Choice Questions: Thought-provoking questions that get me thinking about the verse from different angles.
4. Goals and Daily Reminders
Consistency is everything in memory work, so I built in reminders and XP-based goals to stay motivated. I set my personal goal to 150 XP and 15 lessons daily—something that keeps me pushing forward in a manageable way.### How HideTheWord Has Impacted Me
HideTheWord has made scripture memory feel attainable and genuinely rewarding. It’s no longer just something on my to-do list but a meaningful part of my routine. My hope is that it can help others find the same sense of growth and accomplishment.
Would love to hear your feedback and thoughts!

15. Show HN: Fuzzy deduplicate any CSV using vector embeddings
Author: remolacha
Description: I made an app to fuzzy-deduplicate my Google Sheets and CRM records
- No manual configuration required
- Works out-of-the-box on most data types (ex. people, companies, product catalog)
Implementation details:
- Embeds records using an E5-family model
- Performs similarity search using DuckDB w/ vector similarity extension
- Does last-mile comparison and merges duplicates using Claude
Demo video: https://youtu.be/7mZ0kdwXBwM
Github repo (Apache 2.0 licensed): https://github.com/SnowPilotOrg/dedupe_it
Background story: My company has a table for tracking leads, which includes website visitors, demo form submissions, app signups, and manual entries. It’s full of duplicates. And writing formulas to merge those dupes has been a massive PITA.
I figured that an LLM could handle any data shape and give me a way to deal with tricky custom rules like “treat international subsidiaries as distinct from their parent company”.
The challenging thing was avoiding an NxN comparison matrix. The solution I came up with was first narrowing down our search space using vector embeddings + semantic similarity search, and then using a generative LLM only to compare a few nearest neighbors and merge.
Some cool attributes of this approach:
- Can work incrementally (no reprocessing the entire dataset)
- Allows processing all records in parallel
- Composes with deterministic dedupe rules
Lmk any feedback on how to make this better!

20. Show HN: I made a web browser game with AI integrated NPC’s
URL: https://www.letsmaketv.com
Author: bmdsxl
Description: As of today the game’s demo is officially live and playable at https://www.letsmaketv.com
It’s a web browser game, no sign in or downloads required!
The game uses fine-tuned OpenAI models to simulate the personalities of six different NPC’s, each with their own unique training data and personalities.
You can chat with the AI’s about anything, become friends or enemies with them and find out their secrets. The dialogue is surprisingly funny sometimes but it’s still just very much a proof of concept.
There are also a few minigames you can play with the AI too.
I’ll leave it there an let the game speak for itself. I would love it if you played and shared your feedback! I plan to keep working on this game and evolve it into something much broader but for the time being I wanted to share this big milestone!
Let me know what you think!

22. Show HN: Convert any website into a React component
URL: https://chromewebstore.google.com/detail/html-to-react-figma-by-ma/chgehghmhgihgmpmdjpolhkcnhkokdfp
Author: alexdanilowicz
Description: Hey HN, we built a Chrome Extension (https://www.magicpatterns.com/extension) that converts a snippet of any website to an isolated React component.
Demo video: https://youtu.be/hutUYDkyE_A
How it works: 1) Iterate through each node in the selected DOM tree, 2) For each element, find any matching CSS selectors / inline styles, 3) Use window.getComputedStyle to get the deterministic values, 4) Construct JSX
It was pretty hard producing the minimal code necessary while maintaining the same visual look. To do this, we implemented things like abstracting out global styles, removing inherited styles, pulling out SVGs, deleting styles with no effect, and condensing styles into their shorthand properties.
We dive into each of those optimizations here for fun: https://www.magicpatterns.com/blog/any-website-to-react-comp…
One of the main reasons we cared so much about condensing down the styles was not only to make it more human-readable, but also to reduce context length for an LLM, so that you can iterate on it with AI. Our extension has a “convert” option that lets you convert the output to Tailwind, Shadcn, or Chakra UI using an LLM. You can also export to Figma.
We’re frontend engineers and we built the extension because our core product (https://www.magicpatterns.com/) helps software teams prototype their product ideas. And a huge pain point for users is getting their existing designs into our product, so that they can reference them to generate UIs with their existing aesthetic.
The extension allows you to get existing design context from any website, even localhost. Since launch, the extension has more than 3,000 users and interestingly is most popular in Japan.
Here’s some real examples if you’re curious what the final output looks like:
A) Hacker News Navbar - https://www.magicpatterns.com/ac9f38e4-5ef0-49e5-8b80-dbc429…
B) ChatGPT Welcome Screen - https://www.magicpatterns.com/7cb3ad12-cb12-4a5b-b32b-eda04d…
C) Cal.com Calendar Component — https://www.magicpatterns.com/a43bac78-134d-458d-8107-811ac7…
D) Stripe.com logo section - https://www.magicpatterns.com/deff1793-7a05-42fe-97f7-945976…

23. Show HN: Happy Inbox – Privacy First Gmail Cleanup
URL: https://www.happy-inbox.com/
Author: pavankumarkota
Description: Hey HN,
I have always been one of those who finds it very hard to maintain a clean inbox. Two main issues stood out: first, Gmail doesn’t make it easy to identify the biggest space hogs, and second, deleting large quantities of emails isn’t intuitive. I realized that inbox cleanup could be much simpler with the right approach.
Problem with existing solutions: When I looked for tools to solve this, I found they were either pricey or selling user data to third parties. For me, email holds some of my most sensitive personal data, so data-sharing was an absolute dealbreaker. Plus, Gmail cleanup is usually done periodically, so paying monthly fees wasn’t convincing enough.
What Happy Inbox does differently: Happy Inbox organizes emails by volume. For example, if you have 1,800 emails from “Amazon Promotions,” we group them in a “1500+” bucket, making it easy to delete all with a single click or selectively choose what to remove. This feature gives users clear insight into their top space consumers and an efficient way to clean up, all while prioritizing privacy. So you can check once in a while and clear out your top space cloggers and easily get back your inbox space. Easy-Peasy!!
Our journey so far: We launched Happy Inbox four months ago and have grown organically helped people worldwide delete over 6 million emails, showing just how much inbox clutter people are dealing with!
We’d love to hear your feedback and any ideas for improvement. Try it out here: www.happy-inbox.com

30. Show HN: Mem0 Browser Extension: Shared Memory Across ChatGPT,Claude,Perplexity
URL: https://github.com/mem0ai/mem0-chrome-extension
Author: staranjeet
Description: Hey HN! We’re Deshraj and Taranjeet. We’ve been building working on a startup called Mem0, building an open-source memory layer for AI apps and agents (https://news.ycombinator.com/item?id=41447317). We also kept running into our own daily frustrations with AI assistants forgetting everything between conversations. Over a weekend, we decided to hack together a Chrome extension to solve this for ourselves.
The problem was simple: we were constantly re-explaining our context across platforms when switching between ChatGPT, Claude, and Perplexity. Start a coding discussion in ChatGPT, switch to Claude for a different perspective, jump to Perplexity for research—you’re starting from scratch each time. We thought others might find this useful too, so we’re sharing it with the HN community.
Our solution is built on our unified memory layer that works across multiple LLMs, accessible through a simple Chrome extension. Here’s a quick demo of how it works: https://youtu.be/cByzXztn-YY
The key features include
- Cross-LLM Memory: Start a conversation in ChatGPT, then continue in Claude or Perplexity without losing your context. This makes it easy to switch between models while maintaining coherence in your interactions.
- Customizable Control: Our dashboard lets you manage memories directly—you can add, edit, or delete memories, ensuring that your context stays relevant and accurate across all your LLM interactions.
- Sync with ChatGPT Memories: If you’ve been using ChatGPT’s memory feature, Mem0 can sync with it, creating a consistent experience across your preferred LLMs.
We use a hybrid data architecture that combines graph, vector, and key-value stores to manage memories. This setup enables efficient memory retrieval based on relevance, recency, and context, ensuring your interactions remain meaningful across all apps.
The Chrome extension is MIT licensed and available on GitHub. Currently, it uses our hosted version of Mem0 for simplicity and stability. But we plan to add support for self-hosting using the open-source version of Mem0.
Try it out:

Author: lucasllinasm
Description: Our initial intention was to experiment with a smartbook idea, but we couldn’t find a good prototyping tool for small/specialized AI models. That rabbit hole took us through vector databases, through infra for small AI, and finally here.
We’re particularly proud of the accessibility/simplicity of our code syntax.
Krixik’s model library is limited to eleven model types (modules) and a few dozen models, but we will significantly expand it. Other enhancements, like a local client and several 3rd-party integrations, are also planned.
You require API credentials to try Krixik. You can quickly get them through this form: https://forms.gle/WZ6PegC7pcmuGNNC9

URL: https://git2blog.streamlit.app/
Author: muc-martin
Description: I put together a prototype that generates blog posts from Git commits. It’s a way for small businesses or solo devs to keep their blogs updated with relevant content without writing new posts every time. You enter your repo and a date range, and it creates a short summary of recent changes – useful for keeping your blog active and potentially improving SEO.
It’s still pretty basic, so I’d really appreciate any feedback. Do you think this could be helpful? Any ideas on how to make it better for SEO?

45. Show HN: I made a simple VSCode extension to sort and compare jsons
URL: https://marketplace.visualstudio.com/items?itemName=farzan-tinati.json-sort-and-compare
Author: pharzan
Description: There is no guarantee that two generated JSON files will have the same order of keys and values, which can make comparing two JSON files difficult, even if they are identical in content but different in order. To solve this issue, I created a simple VSCode extension that sorts and then compares two JSON files.

48. Show HN: A free quantum computing course
URL: https://qcfundamentals.com/
Author: dazkins
Description: I’ve spent the last 6 months writing a completely free, “mathematics first” quantum computing course.
I mostly did it for myself, to help my own learning, but I hope the articles will prove useful to others looking for a more math centric approach to the subject.
The course goes from an approximately high school level of math to Shor’s famous quantum factoring algorithm.

59. Show HN: Bento Decks for VCs
Author: shav7
Description: Many VCs mentioned dealing with 100s of inbound pitch decks, and trying to determine the noise-to-signal ratio / alignment with their thesis is frustrating. So we decided to do a two-day sprint to solve this.
Built Bento Decks where you can upload your thesis and founder decks to get an output that evaluates alignment percentage and generates a TL;DR of the deck that can be shared with others.
