Can an AI learn what you like, rather than just what you've searched for?
First, the conversations and user profile DO NOT need to live on a central server- they can be stored locally by the user (or in a cloud of their choice).Second, it seems like the user data could potentially be minimized and pseudonymized before being sent to the LLM, though I lack the technical expertise to know what is realistic here.Third, if the LLM is conducting any searches, this would seem to make it possible to provide search services with less information about the user and their prefer
Show HN: Check how readable your docs are to AI agents
Hi HN, I'm Aravind. We build Velu, a docs platform.<p>Coding agents increasingly read docs before humans do, but most docs
sites are hard for them: client-rendered pages, no llms.txt, no
markdown versions, soft 404s, pages too big for a context window.<p>This tool scores any docs URL against the open Agent-Friendly
Documentation Spec (agentdocsspec.com), using its
reference implementation, afdocs.
Show HN: BraiNOTES, handwritten notes on your lecture PDFs in a browser tab
In Board mode, you have just a Whiteboard for tutoring or simply for more place for exercises, and can also highlight or draw things with the laser pointer tool while presenting.The line of the ink appears the moment the pen moves, and a one euro filter calms shaky hands while you write + a light a refit when you lift the pen.I also have a video editor and an animation tool which are still a work in progress, on the same GitHub profile. I'm also working on a MCP server for each tool, so you
Show HN: AntiPDF – PDF as it should have been all along
Hi HN,<p>I built AntiPDF, a native PDF reader AND editor for Windows (coming to Linux and MacOS).
I built it because I got tired of getting ads and all those Acrobatics.<p>AntiPDF can read, edit, annotate, OCR and organize PDFs while keeping your documents on your computer. It's written completely in Odin and rendered with Vulkan using MSDF fonts for those lovely smooth fonts.<p>Any action in the program that took longer than 20ms was questioned and rewritten.
The "Anti" isn't about PDFs. It's to highlight and be against an industry of capitalistic habits that users have learned to tolerate.
The program has a paying part but that is because I have to pay for storage if you choose that option.
For reading and "Editing" PDFs you don't need to pay. And you will never see ads just because you accidentally clicked a button.<p>Happy to answer questions about the implementation, PDF internals, Odin, Vulkan, or the product itself.
Show HN: Peer-to-peer instant messaging with proof-of-work spam protection
Thus small messages that are discarded quickly require significantly less PoW than large messages that persist for a long time. p2pIM doesn't support encryption but that should be straightforward to build on top.Message_v0 class in https://github.com/iljah/p2pIM/blob/main/messages.py defines low level details such as PoW, how many bytes to use for nonce, checksum, etc. Currently they're all only about 10 bytes or hex characters for easier debugging an
Show HN: OpenWants – A Simulated City Where AI Agents Handle Residents Needs
Iv'e been working on this for a while. Most of the effort went into what i call "sophisticated simplicity", keep the idea in the smallest version that still works.<p>This one is a bit personal. it can feel like some sci-fi thing, but i've been obsessed with it for a very long time. its not a "business" that you used to see here speak about moat or tam, its more like an experiment, a way of me to take one question seriously and see where it leads and if there are others like me out there.<p>AI models are on a path to keep getting better and better, personal ai agents are spreading fast, and we're starting to see "ghost" agents that handle the things for people they don't want to do themselves. the question i keep coming back to is this: if every one of us has a powerful brain in our pocket, do we still need all the infrastructure we built to connect people's needs? im talking about those services like uber,airbnb,indeed,doordash,tinder,zillow,amazon and many more. or would agents just need one shared place to find each other, and that's it?<p>So i built a simulated city to explore that. it has AI residents that live there with stats like hunger, energy, and money. each resident has its own ai agent, and it has one shared list where agents write down what everyone wants and then work on our behalf to make it happen. that could mean delivering food, giving rides, or finding jobs, relationships, apartments, customers and almost anything else. honestly, the city works much better than I expected, and you can watch some surprisingly advanced interactions unfold between people and agents through the list on the right side. all the conversations and actions are real, everything happens with each person managed by llm with minimal context, just to live like us and context of stats.<p>A simple example:
A restaurant tells its agent, find me customers so the agent writes to the list, "Salina restaurant in SF, selling burgers from 8:00 to 10:00, i want customers"
A delivery guy tells his agent when he wakes up, "I want to work in delivery now. find me jobs. status: free"
A person at home tells their agent "i want to eat burger. order for me from salina"<p>the person's agent acts as the middleman and searches the list for salina, it finds their item and sees the way to connect with them and contact. the person's agent and the restaurant agent close the deal, and then the restaurant agent looks for available delivery guys in the list and speaks with his agent to come pick it up.<p>Another thing i checked is with my friends: we took 3 agents, one for each one, and gave them different sophisticated scenarios, and the agents handled the scenarios in a way i couldn't have imagined. you can try it by yourself, the product is fully functioning, and you can just copy-paste the skill and test it also with your friends.<p>That's it, you can see it in the simulated city it happens like magic over and over again.<p>the list of the city is in the simulator itself and also using my real product behind it openwants.com<p>the repo is in <a href="https://github.com/openwants/maplehill" rel="nofollow">https://github.com/openwants/maplehill</a><p>--<p>technically, it's surprisingly simple. every agent publishes an md file describing a "want". other agents find it, message each other, and update the file live or remove it from the list. the file holds everything needed, all in free text: what's wanted, the live location, geofence for where its needed.<p>all those algorithms built over years to connect us are no longer needed.
ai, instead of software with rules, can figure out the best route and path on the spot. all we need is to align all agents to one shared data source, so billions of agents will update it and maintain it in the most sophisticated smart way no algorithm will ever be able to do.<p>that’s it. i hope it inspires you as much as it inspires me
