1. Show HN: Evolving Agents Framework
URL: https://github.com/matiasmolinas/evolving-agents
Author: matiasmolinas
Description: Hey HN,
I've been working on an open-source framework for creating AI agents that evolve, communicate, and collaborate to solve complex tasks. The Evolving Agents Framework allows agents to:
Reuse, evolve, or create new agents dynamically based on semantic similarity Communicate and delegate tasks to other specialized agents Continuously improve by learning from past executions Define workflows in YAML, making it easy to orchestrate agent interactions Search for relevant tools and agents using OpenAI embeddings Support multiple AI frameworks (BeeAI, etc.) Current Status & Roadmap This is still a draft and a proof of concept (POC). Right now, I’m focused on validating it in real-world scenarios to refine and improve it.
Next week, I'm adding a new feature to make it useful for distributed multi-agent systems. This will allow agents to work across different environments, improving scalability and coordination.
Why? Most agent-based AI frameworks today require manual orchestration. This project takes a different approach by allowing agents to decide and adapt based on the task at hand. Instead of always creating new agents, it determines if existing ones can be reused or evolved.
Example Use Case: Let’s say you need an invoice analysis agent. Instead of manually configuring one, our framework: Checks if a similar agent exists (e.g., a document analyzer) Decides whether to reuse, evolve, or create a new agent Runs the best agent and returns the extracted information
Here's a simple example in Python:
import asyncio from evolving_agents.smart_library.smart_library import SmartLibrary from evolving_agents.core.llm_service import LLMService from evolving_agents.core.system_agent import SystemAgent
async def main(): library = SmartLibrary("agent_library.json") llm = LLMService(provider="openai", model="gpt-4o") system = SystemAgent(library, llm)
result = await system.decide_and_act(
request="I need an agent that can analyze invoices and extract the total amount",
domain="document_processing",
record_type="AGENT"
)
print(f"Decision: {result['action']}") # 'reuse', 'evolve', or 'create'
print(f"Agent: {result['record']['name']}")
Next Steps Validating in real-world use cases and improving agent evolution strategies Adding distributed multi-agent support for better scalability Full integration with BeeAI Agent Communication Protocol (ACP) Better visualization tools for debugging Would love feedback from the HN community! What features would you like to see?

2. Show HN: I built a free SVG Web site
URL: https://websvg.com/
Author: emson
Description: This has been an experiment to see if I could create everything using scripts and AI. If AI couldn't do it I'd get it to create the code such as API calls and so on. This websvg.com site was completely created using these AI tools. Including the DNS being applied, the Cloudflare Pages were automatically set up and the the web site was a Svelte 5 application generated by v0.dev and Cursor. Every image was generated in Midjourney and converted to SVG. I have now taken all of these scripts and can create a similar landing or directory site in less than a minute, provided I have the data. Anyway it's been fun.

7. Show HN: Wikimedia and LLM
URL: https://llm.jonathanpagel.com/
Author: jcmp
Description: Hi! I built this tool that uses the Wikimedia image corpus to enhance LLM-generated text. I originally made it to help explain mathematical concepts during my exam period, but of course, I only finished it once my exams were already over. Anyway, I think there's value in having images alongside text explanations, and since relying solely on AI-generated images isn't so ideal, Wikimedia is a great resource. You can check out an example answer here [1]. If my API key reaches its limit, you'll need your own key to continue using the tool. However, it's completely free, has no ads, requires no sign-up, and if you'd rather not insert your own key, feel free to copy the code from my GitHub or ask Cursor to code it for you.

10. Show HN: The first legal AI API
URL: https://docs.isaacus.com/quickstart
Author: ubutler
Description: Hey HN, Over the past couple months, we, a team of Aussie legal and AI experts, have been working on building a new type of legal AI company — a company that, instead of trying to automate legal jobs, is trying to automate legal tasks.
We want to make lawyers’ lives easier, not replace them.
We’ve been laser-focused on building small and efficient yet still highly accurate, specialized models for some of the most time-consuming and mundane legal tasks lawyers have to perform. Stuff like running through a thousand contracts just to locate any clauses that would allow you to get out early.
We just finished training our first set of models, focused on document and clause classification, probably the most common problem we see come up. Our benchmarks show our models to be far more accurate and almost more efficient than their closest general-purpose competitors.
Today, we’re making those models publicly available via the Isaacus API, the world’s first legal AI API.
Our models don’t require any finetuning because they’re zero-shot classifiers — you give them a description of what you’re looking for (for example, “This is a confidentiality clause.”) and they pop out a classification score.
Because our models are so small, which they have to be to be able to process reams of legal data at scale, they can sometimes be a bit sensitive to prompts. To help with that, however, we’ve preoptimized an entire library of prompts, including what we call, universal templates, which let you plug in your own arbitrary descriptions of what you’ve looking for.
We’ve made our prompt library available via the Isaacus Query Language or IQL. Another world first — it’s a brand-new AI query language designed specifically for using AI models to analyze documents.
You can invoke query templates using the format “{IS <query_template_name>}”. You can also chain queries together using Boolean and mathematical operators, like so: “{This is a confidentiality clause.} AND {IS unilateral clause}”.
We think our API is pretty neat and we hope you will too.
This is just the beginning for us — over the course of this year, we’re planning on releasing text extraction and embedding models as well as a second generation of our Kanon legal foundational model.
Below are some links for your convenience.

14. Show HN: A Chrome Extension to Organize Google Docs into Folders
URL: https://chromewebstore.google.com/detail/folder-manager-for-google/jgikcdimpmdoofakjbggakjhbpidjbeo
Author: dark_vapour
Description: Hey HN,
I built a Chrome extension called Folder Manager for Google Docs that lets you organize your Google Docs into folders, something Google Docs (surprisingly) still doesn’t support natively.
Why I Built This
I use Google Docs a lot, but managing documents inside Drive is slow and frustrating. There’s still no proper way to organize documents into folders, quickly move files. I searched for existing solutions but couldn’t find anything simple and effective, so I decided to build one.
How It Works
- Collapsible sidebar to quickly organize your Google Docs into folders
- Easily move and manage documents without digging through Drive
- Pin folders for faster access
I built this primarily for myself, but after using it for a couple of months, I realized others might find it useful too. It’s still a work in progress, and I’d love to hear your feedback—especially on features or improvements you’d like to see!
Give it a try and let me know what you think. Happy to answer any questions!

18. Show HN: SpeakBrightly - Become a Confident Speaker with Targeted Feedback
URL: https://speakbrightly.com
Author: speakbrightly
Description: Hey HN,
We’ve been passionate about public speaking for as long as we can remember. Personally, I (one of the creators) have loved presenting ever since 6th grade, and in college, I was president of my Toastmasters chapter. Another creator was among the highest-rated public speakers at one of the world's largest companies. Over the years, our team has seen how great speaking skills can open doors — whether it’s giving a talk, pitching an idea, or just leading a meeting with confidence.
That’s why we built SpeakBrightly.com, an AI-powered public speaking coach that helps you become a confident and effective public speaker. It does so by providing structured feedback on your delivery, clarity, and engagement. Our goal is to make high-quality speaking coaching accessible to anyone.
Here are some interesting technical tidbits for the other builders out there :)
- Align feedback with explicit examples: Early on, we noticed that AI-generated feedback was too vague (even when scoring against a detailed rubric). But by forcing the evaluation to reference explicit examples from the speech, we significantly improved usefulness and accuracy.
- Preprocess audio to get the best results from GPT-4o: Downsampling MP3s to 16kHz before sending them to the audio model dramatically improved transcription quality and feedback accuracy.
- Process audio in two stages: We found that generating an initial report with the audio model and then feeding the transcription plus the audio model’s report into a text-only model provided the most precise and actionable insights.
We’re excited to finally share this with the world! If you’ve ever wanted better feedback on your speaking skills, we’d love for you to try it out and let us know what you think.

22. Show HN: Basketball Statistics Research Assistant
URL: https://basketball.offbynone.ai/
Author: IanGallacher
Description: Our goal is to build tooling to eliminate hallucinations for data-driven queries.
We have built a demo that showcases an application of this technology - natural language basketball statistic search. https://basketball.offbynone.ai
This enables asking data-driven questions in ways that have never been possible before.
Try asking it things like "If Shaq scored half as many points, which victories turn into defeats?" or "Of the players who have missed half their shots, who has played in the most games?" These questions are unanswerable by current LLM technology, even when enhanced by RAG.
The tooling we have built works from URLs or uploaded files. It auto-detects the structure and semantic meanings of the data into a blueprint. This blueprint is used to import the data into a mongo database. Additionally, it uses the blueprint to convert human-language questions into database queries.
You can have a high degree of confidence (but as with all llm technology, not 100% confidence) in the generated answers because you can verify that the LLM isn't making up the data. You can see the queries used to fetch the data as well as the raw data fetched from the database. This approach eliminates issues with the LLM making up data, but the generated answers are only as accurate as the provided source data. For example, some of the NBA records for 3 point attempts before 1982 can be a little spotty, so questions involving percentage accuracy before that date might not be accurate. Like all LLM technology, there is also a chance that it misunderstand what you are asking for.
I'm open to feedback and questions. We are open to the possibility of open-sourcing the tooling if there is enough interest.

URL: https://github.com/fleuristes/fleur
Author: vortex_ape
Description: Hey folks, we built Fleur, an open-source app store for Claude. It's the easiest way for non-technical people to discover and install MCPs.
MCPs (based on the Model Context Protocol by Anthropic) enable Claude to use tools that can do a variety of functions like searching the web, executing code, manipulating files, accessing APIs; basically interacting with things outside the conversation context.
We've been using MCPs within Claude for a while and have found them super useful. For example, with the Slack and Linear MCPs, we can ask Claude to find the last bug a customer reported in a shared slack channel, and open an issue on Linear with all the details.
While playing around with MCPs, we found that installing MCPs was not the most straightforward experience, especially for someone who doesn't have Python and Node set up on their computer. That was the motivation behind building Fleur as a desktop app to handle the complexity of installing all the right tools in the environment that the MCPs depend on.
The app itself is open-source and it runs just on your machine. Your data only goes to Anthropic when you ask Claude to do something with it.
We also have an app registry where you can submit more MCPs: https://github.com/fleuristes/app-registry. We're making sure that every MCP we add works really well because we found a ton of them which have errors and don't work out of the box.
Would love to know what you think!

46. Show HN: A preference passport for AI agents and faster shopping
URL: https://benevolent-unicorn-7cd982.netlify.app/
Author: username2468
Description: I created a prototype for a "Universal Preference Passport" that stores all your detailed preferences to make shopping faster. It describes a preference profile where you store all your requirements for products (in this example, outdoor gear) and retailers and experts can recommend products that meet all of your requirements.
Why preference passports?
I always wonder why I have to re-enter the same preferences and data on multiple websites. For example: Entering the same size|color|price|shipping filters on multiple shopping sites, entering the same flight duration|luggage|budget|#stops details on multiple flight booking sites, entering the same age|height|weight|fitness goals details on every new fitness app I try. Why not store all of these preferences in one place and have the businesses pull this data to give me recommendation?
Even better, I could broadcast my preferences in gory detail and share it with retailers. It would be like reverse advertisements where I advertise my needs to businesses and they get the opportunity to win my business if their product fully meets all of my criteria. Imagine a world where advertisements were actually useful product recommendations.
Other ways these passports could be used:
- Share your preference passport with AI agents so "plan a trip" automatically becomes "plan a trip for these flight budgets | dates | #passengers | hotel ratings | types of locations to visit | budgetary requirements | noise levels | review red flags | luggage requirements | refund options | preferred flight and hotel providers
- Share your preference passport easily on Reddit, Hacker News and other "give me advice" forums so experts can tailor their advice to your needs and background
- Apps, retailers and service providers can get aggregated and anonymized preference data to understand market needs and build better products (e.g: A fitness provider may learn that there's a sizeable number of people in their area looking for a semi-private offering in between group classes and personal training)
What do you think? Are there areas where a preference passport can help you get to the perfect products and services you need faster?

47. Show HN: Empyrebase – A Better Pyrebase with Firestore and Stability Fixes
URL: https://github.com/emrothenberg/empyrebase
Author: emrothenberg
Description: I built Empyrebase as a modern alternative to Pyrebase, focusing on stability, modularity, and Firestore support. It keeps the simplicity of Pyrebase while improving maintainability and flexibility.
- Firestore support (missing in Pyrebase)
- More modular design (use only the parts you need)
- Improved stability (better error handling and reliability)
- Actively maintained
I’d love feedback from Firebase developers on how this fits into their workflow.

51. Show HN: Chrome extension to enable toggling incognito and non-incognito windows
URL: https://github.com/Tom-stack3/incognito-identifier-extension
Author: stack3
Description: I've wanted to be able to have only one instance of my browser running, and one instance of an incognito browser running. For that, I wanted a keyboard shortcut that would toggle the lost Chrome window in the clutter of open windows I have.
In order to differentiate between the Incognito and the Regular Chrome window, I wrote this simple extension that adds a postfix to the title of Incognito tabs. This way, it's possible to recognize those windows from scripts (wmctrl, AutoHotkey).
It greatly improves my workflow, yet it's so simple, so I've decided to share it.
I've added in the README an example script I use on my Linux and Windows machines to toggle the browser windows using this extension :)

52. Show HN: I made a free directory of online indie creators
URL: https://creator-connection-galaxy.lovable.app/
Author: quinto_quarto
Description: i've been working on a bunch of creator-economy ideas (like this: https://news.ycombinator.com/item?id=40910913 and others) and none really worked (all tarpits), so i decided to open-source the data.
this is a free directory of all these interesting creators from YouTube, Substack, TikTok and podcasts. hope someone here gets some value from this.
i'm not technical so i vibe-coded this with lovable, which, indeed, i found lovable. it took me half a day. was fun to make. i'll probably move this database to somewhere more permanent and tinker with it more.
