Products that do what Self-host your data anonymization pipeline does

Needed this in my own work, anonymizing PII/PHI and decided to build this because presidio didn't really cut it for our use-case. Try it and maybe let me know if you have any feedback :)

    Everything that would be here is in the README. I hope this gets big, it has tons of potential.

    Hi hackers, long time reader, first time "real" submitter. This is by no means a revolutionary idea, or even execution, but rather something I've always wanted to do, just to see if I could write a good implementation of it. So without further adieu: http://ca.pitali.st/ Yes, it's just an URL shortener. Please check out the API and if there anything you like about it, please share, so I can take this feedback with me to my future projects. If there's something you REALLY hate, that's feedback too. Don't be afraid to hurt my feelings; this was put together in less than 4 hours to see if I…

    Anonymize prompts privately and securely

    I spent the past few weeks making an open source cloud code editing environment with an AI copilot and multiplayer collaboration! It's fully self-hostable in 5-10 minutes. There's a lot of minor improvements to be made, and some are already listed in the Github issues. Let me know what you think and feel free to try it out.

    Hi there! I've been working with data in one form or another, professionally, for about 5 years. I've been thinking about my own personal data and how it's used for at least twice that long. I've been sort of building something in my head for a while that solves my own problem and, in the beginning of this year, I found the opportunity to spend some time building it out. I'll leave the detailed explanation to the blog post but, in short, I built what amounts to an API crawler combined with a data processor to help you download your personal data from 3rd party services and work with it using…

    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.

    Hi HN, I'm the creator of epress. After a lot of work, I'm excited (and a bit nervous) to finally share it with you. For years, I've been feeling like a digital tenant on the platforms I use every day. My content, my social graph, my online identity—they were all stored on someone else's servers, subject to their rules, algorithms, and business models. I could be de-platformed, my data could be sold, or an API I relied on could suddenly be put behind a paywall. I looked into existing decentralized alternatives. While many are great projects, I found they often shifted the trust from a big…

    Batch PII anonymization with encrypted local vault

    orignally shared this on startup school... i thought id' share it here. i'm using a `nocode communication tool` (a web-based interface... a single browser tab!) for all of these things: 1. landing page — the landing page is the product and i wanted for folks to feel "transported" right into the app without having to walk through a shitty b2b marketing-style content. this is akin to my experience back in the `BBS` days of the mid-90's where you were immediately into the app, community, and tool. no terms of service, no privacy policy. just pure, immediate value. 2. building community — we…

    I know everyone is a bit burned out on blockchain and cryptocurrency related stuff around these parts, but I've been working on as a side project for the last few months and thought you guys might be interested: https://cryptoempire.io/ It's still a bit buggy and incomplete (the mobile ux needs a lot of work, the leaderboard isn't functional yet, etc.), but I've reached a point where I'm not totally ashamed of sharing it :) Any feedback would be most welcome!

    Hi HN! I've been hacking on this side project for the last month or two with the goal of making it dead simple to use cloud GPUs. I ran into this problem personally during the phd, and built my own tooling around it. I always thought it'd be fun to try to turn that tooling into a more general product... and bitbop.io is the result! All you have to do is run `ssh bitbop.io`, and you get your own personal dev GPU workstation in the cloud. Looking forward to hearing your thoughts!

    Hello. I made this project as an experiment in using key cryptography for user identity in a client server model, and for some future peer to peer projects that I am working on. I am looking for feedback, please let me know what you think. Also, Merry Christmas to HN! :-)

    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…

    Hi there Hacker News, I've started a side project http://datasourcehub.com which aims to be a platform for data scientists. The project is still in the idea phase so the UI/UX and functionality are all subject to change. Feel free to play around, below is a guest login, and make sure files are content type of 'text/csv'. All data is subject to deletion, it's just a sandbox right now! By reaching out to the Hacker News community I hope to reach expert data scientists and get their feedback. Below are some questions I'd like to answer and some proposed directions that this…

    Would like to share here a project that we have been working on for the last ~10 months. It all started with the goal of properly blocking adult & explicit content out of our own kids devices and expanded it to a free service that anyone can use. Feedback is welcome: https://cleanbrowsing.org CleanBrowsing is free Anycast DNS resolver that automatically blocks adult content and enforces safe search on Google, Google Image search, Bing, Youtube, etc. We have been crawling and categorizing the web for many months and we feel it got to a point where our database is large enough and we…
