Products that do what ZkPaper – Untraceable Document Editor with Proof of Authorship does
Hi! I made this as a hackathon project, the result is really cool and works very well. All you need to do is connect with your Metamask wallet and start creating documents. It also has proof of autorship, so we know if you wrote the document, or you just copy/pasted from chatgpt. This could be useful for schools or something. Let me know what you think. Thanks!

Hey guys, I love HN! I wanted to extend the same aesthetic and community towards things beyond tech-related news. I thought it would be cool to get the same quality of community gathered around the latest and greatest research coming out. Let me know what you guys think of what I have so far. It's still early so there are probably bugs and other quality issues. If there's any features missing that you'd want let me know. ALSO, if any of you are familiar with the map of the territory of any particular field, please let me know! Would love to pick your brain and to come up with a 'most…

Hi HN, We (myself, Adhyyan1252 and yush_g) are undergrad students that hacked out this side project last month during Hack Lodge[1] (the ideas and many of the underlying circuits for which came from the 0xPARC community[2])! We’re extremely excited to share this new primitive. Besides the technical challenges building this project that folks here would find interesting (fixing the ZK proof compiler, modifying nodeJS V8 params etc.), we think this is a very novel use case for ZK tech, and ECDSA inside ZK-SNARKs is a starting point that unlocks many other ideas! :D A summarized version of our…

My personal itch to scratch just recently has been the umpteen formatting foibles of HackerNews. So, in the spirit of making the web more personal again, I knocked up a TamperMonkey userscript to fix up the worst of my personal bugbears. This isn't an attempt at a complete rebrand/redesign of the site, instead it's just fixing up what I think are the biggest design/readability issues whilst trying to remain true to the site's existing aesthetic. Key features: * Base font size increased * A little more room around headings * Top menu bar is full-width and with a little more padding…

TLDR, Let's Seal gives the finger to Adobe and every doc signing tool (docusign, google, etc) who pay to play with the Adobe Approved Trust List and then charge you for something that should be free. Currently even the person checking if a document/contract is sealed or code is authentic has to also be inside the same Adobe walled garden too. Verification, the part that should be free is the part everyone charges for. Thats the shape Let's Encrypt fixed for TLS, and I wanted the same thing for documents and files. The core idea therefore needed to go a bit beyond e signatures and i…

Hey HN, I'm a longtime reader and this is my first Show HN (exciting!) It's a collaboration between me and two friends, and we're building this upon another app we made called EmailYak, an API to receive email. We're trying something new and releasing the documentation to an app while we're still building it. We'd love feedback. Do you belong to any of these categories? 1) You've built an app with two distinct groups of users (say, people with cars and those looking for a ride) and they were able to communicate with each other. Did you expose personal email addresses? Did you send…

Hey developers I think we're tired of copying and pasting our codes and sharing links using PasteBin, GithubGist, or Slack. What if you could share the codes without copying the link and share them right from your favorite editor? That was the motivation for creating TurboGist. Right now, it's still in the MVP stage, and I'm trying to gather feedback from developers like you. It's available as a beta in the VS Code Extension store. Can you guys check this out? It'd help me a lot. You don't need to pay any penny, 100% FREE. However, I'm working on introducing a self-hosted feature. Besides, a…

Hey HN, I wanted to share something I’ve been working on: *RAG-Guard*, a document AI that’s all about privacy. It’s an experiment in combining Retrieval-Augmented Generation (RAG) with AI-powered question answering, but with a twist — your data stays yours. Here’s the idea: you can upload contracts, research papers, personal notes, or any other documents, and RAG-Guard processes everything locally in your browser. Nothing leaves your device unless you explicitly approve it. ### How It Works - * Zero-Trust by Design*: Every step happens in your browser until you say otherwise. - * Local…

https://github.com/inoda/private_journal Built this to use myself, and I'm curious if anybody would be interested in using it. I'm also wondering if anybody has tips to make it more secure (I'm super super new to encryption and whatnot). The security is probably a bit overkill since chances are that nobody cares about what I'm journaling, but it is fun to implement from a code standpoint.

Hello HN, Over the last year we've been building snote.app, a Privacy focused, End-to-End Encrypted alternative to Notion. You can write, plan, collaborate and get organized - it allows you to take notes, store files, add tasks, manage projects & more. Whether you're working solo or in a team. We are hoping to use this post as an opportunity to collect feedback from fellow hackers. If there's anything we can do better, please let us know

Hey HN, Along with a handful of friends, I've been working on a note taking platform for the last couple years. We created a 2 minute pitch of our platform, if you'd prefer to read, maybe you'd want to checkout our README: https://github.com/lockbook/lockbook. If you don't want to do either of those things I'll try to summarize some of our core values: - everything end to end encrypted - open formats: markdown and svg - strong offline support - everything open source - native apps where possible - rust where possible Some other stuff we're proud of: - we have a CLI which…

Hey HN peeps! I've been working on coverlettergpt.xyz for the past few weeks. It was recently featured in the IndieHackers newsletter[0] and is just shy of 900 users. You can use it to generate cover letters by copy & pasting the job description, uploading your CV/résumé, and changing a few settings. The app will then generate cover letters for you, which you can further edit with GPT. You can also manage your jobs, create multiple cover letters per job, and other fun stuff. I'm honestly quite surprised at the response to it, as it's "yet another GPT wrapper," but I've built in some…

I've always been fascinated by cryptographic principles, so I decided to dive deep into zero-knowledge proofs and implement a Groth16 proof verifier entirely in Rust. This project validates cryptographic proofs and demonstrates how succinct, verifiable computations can be achieved. Using Rust's powerful libraries like arkworks, I implemented pairing checks, public input commitments, and proof validation logic while ensuring the code remains modular and efficient. I handled the complexities of affine group operations, scalar multiplications, and optimized public input verification to make…

A friend and I built this as a side project to help us collaborate on files with our agents. Claude / Codex kept outputting .md and .html files which are great until we needed to share them, so we built this small website to help with that. Agent can either use an HTTP + Skill or an MCP which also uses MCP Apps to add widgets to Claude Desktop / Mobile chat. Would love any feedback and hopefully this helps someone else as it did us!

Hey HN, A long time ago, due to the lack of viable solutions with E2EE and offline-first syncing, I decided to dedicate my time to making one (which has its own story: https://yaad.one/blog/yaad-story). In the course of ~3 years, I developed a knowledge management app with these primary features: - Primitives: Notes, Tasks, Contacts - Grouping with "Boxes" - Offline-first - Multiplatform; currently available for Android, Windows (x64), macOS, and Linux (ARM). - Fully end-to-end encrypted (AES-256-GCM) - 13 Languages, 8 calendar systems - Light & dark mode Last night, I…

Hello everyone! I always found it hard to find new research papers outside of my usual bubble. I thought a random feed (with no recommendation algorithms) might be a fun way to explore. But I also didn’t want to waste time on completely unrelated stuff — so the idea of a fast, swipeable format came to mind. Wikitok was a real inspiration! But Arxiv and Open Review APIs weren’t as robust as Wikipedia, so I pulled the papers into a Postgres backend. Right now, I’ve indexed papers from a few recent ML conferences to see if this might be useful for others too. No signups required and it’s…

Long story short: After heartbleed thingy decided to use a password manager. Didn't want to buy one. Didn't like KeepassX interface. Started using MacPass. Tired of bugs and form fillings. Decided to make my own text editor that can encrypt saved files with password. Try it out here: http://textcrypt.4apps.lv/app/updates/TextCrypt_1.0.424.zip and let me know what you think. Would you use it? Any feedback, suggestions which direction to go? p.s. Its an early Alpha version.
