24 alternatives to RAG-Guard: Zero-Trust Document AI

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…

    I built this tool because I wanted a way to just take a bunch of URLs or domains, and query their content in RAG applications. It takes away the pain of crawling, extracting content, chunking, vectorizing, and updating periodically. I'm curious to see if it can be useful to others. I meant to launch this six months ago but life got in the way...

    Hi HN, I built CountermarkAI, a lightweight anti-scraping & bot-detection tool for content creators and website owners. It’s designed to help protect your work from unauthorized scraping and AI training, that repurposed your work without permission. How It Works: Use Hashtag – Creators add a unique hashtag to their content as a declaration of ownership. Protect Website – For those running your own sites, simply add a small snippet to your . The protect.js script works asynchronously by sending metadata from every page load back to our servers, logging requests, and flagging known AI-training…

    I haven't seen anything like this so I decided to build it in a weekend. How it works: You see a bunch of things pulled from Wikipedia displayed on cards. You ask yes or no questions to figure out which card is the secret article. The AI model has access to the image and wiki text and it's own knowledge to answer your question. Happy to have my credits burned for the day but I'll probably have to make this paid at some point so enjoy. I found it's not easy to get cheap+fast+good responses but the tech is getting there. Most of the prompts are running through Groq infra or hitting a cache…

    I built a proof-of-concept for running RAG (Retrieval-Augmented Generation) entirely in the browser using WebGPU. You can chat with PDF documents using models like Phi-3, Llama 3, or Mistral 7B - all running locally with zero backend. Documents never leave your device. Tech stack: - WebLLM + WeInfer (optimized fork with ~3.76x speedup) - Transformers.js for embeddings (all-MiniLM-L6-v2) - IndexedDB as vector store - PDF.js for parsing The main challenges were: 1. Getting esbuild to bundle without choking on onnxruntime-node 2. Managing COOP/COEP headers for SharedArrayBuffer 3. Keeping…

    Hey HN! I got tired of AI agents being a pain to set up, impossible to customize without a PhD, and only viable if you're some Fortune 500 company. So I built something different, a chatbot you can literally drop onto your website with a single script tag. Create an account, add your domain, customize literally everything (theme, icon, welcome message, suggested responses, whatever), and you're done. The bot scrapes your site once a day to understand your business, or you can just upload docs-pricing sheets, policies, FAQs, you name it. That's your chatbot's brain right there. It only works…

    Hey HN! Over the past few weeks, I’ve been working on DataBridge, an open-source solution for data ingestion and querying across text, PDFs, images, and videos. In our latest update, we’ve added a fully local deployment option: - No internet required – Runs entirely offline. - Customizable Models – Supports any LLM and embedding model via Ollama (with options for any other private providers) - Extensibility – You can plug in your own models or tools easily. This local-first approach ensures better privacy, security, and flexibility, especially for teams dealing with sensitive data. You can…

    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!

    I got tired of slogging through walls of legal text whenever I had to sign something important, so I built a Chrome extension that uses AI to: - Spot red flags and suspicious clauses – It automatically highlights risk areas in real-time as you read through an online contract. - Score the contract’s safety – Based on industry-standard risk parameters, it gives you an at-a-glance score so you can see how risky the document might be. - Simplify the jargon – It generates a quick summary of the key points, saving you from reading every paragraph in detail. No more signing on hunches or bets!…

    Hi everyone, I'm a developer building a tool to help automate social media post creation. Before I add more features, I'd love to get feedback from real marketers on whether this is actually useful. Would anyone be willing to try it out and share their honest thoughts? Keep in mind this is just an MVP and not a full blown website (yet), I am just testing to see if anyone would actually use it and then we would move on to making it truly functional and aesthetic. If anyone has actual questions instead of straight hating, feel free to dm me. Thank you! Check it out if you want.

    Hey HN, Since the launch of GPTs, I’ve struggled with integrating vast, up-to-date knowledge into a custom GPT and embedding it into websites and apps. After months of trial and error, we’ve developed an AI Search & Knowledge Assistant that solves this problem. Over the weekend, I built a demo assistant for Stripe that provides accurate answers, useful links, images in responses, cites sources, and keeps a thread history of your conversations. Here’s what’s included: - 3,700+ public documents full of useful info - 105+ million characters of rich knowledge - Powered by the ChatGPT-4o model…

    I have a weird habit of guessing whether something's AI before I check, especially on LinkedIn and Reddit (for obvious reasons). The detectors I used to confirm were mostly junk and built to sell you a "humanizer" upsell, so I went and read the actual research on what gives AI text away in 2026, then built my own (no login and free) The main sources I used are these: https://arxiv.org/abs/2406.07016 https://arxiv.org/abs/2403.07183 https://aclanthology.org/2025.coling-main.426/ https://arxiv.org/abs/2410.16107…

If you decide to test it, try using the prompt: Keep this text and…"(add budget, complete list, organize alphabetically, add their translation, etc.). The first big release is all about modifying your notes with AI prompts. The next big step? Capturing thoughts directly from the mind using brain-to-text technology. There is a 3 days free…
