About Document Chat
I recently Open-Sourced Document Chat — a completely free, open-source platform that lets you upload documents and have intelligent AI conversations with them. Built with Next.js 15, powered by multiple AI providers, and ready to deploy in minutes.

The Problem
We’re drowning in documents. PDFs, Word files, research papers, contracts, manuals, reports — they pile up faster than we can read them. And when we need specific information? We spend hours searching, skimming, and hoping we haven’t missed something important.
AI assistants like ChatGPT have shown us a better way — natural language conversations. But there’s a catch: they don’t know about YOUR documents. Sure, you can copy-paste snippets, but that’s manual, tedious, and limited by context windows.

Document chat is becoming an essential workflow. Being able to query large documents through natural language instead of CTRL+F searching is a genuinely useful time saver.

Nice! And if you ever need DDoS protection with a proper firewall for your website, just let us know!

Very nice to focus on document. A source of inspiration
Congratulations! This is brilliant. Does it matter what format the documents are in? For example, can you upload PDFs, PPT and excel and chat about them all together?
Hey @leah, Thanks for your comment. For now, you can upload and chat with PDF, DOCX, TXT, MD, and images. We plan on extending it to more file types in the future. It supports DocLing, which will make it much easier to integrate later.
@nzouat that’s a great selection to start with!
Wow! You have even included a Stripe integration to monetize the instances! This is something I have never seen someone do before! Founders often host their open-source software on their server to monetize it, not give it away to users.
It's like papra on steroids.
This is great. Free to connect this week or next with the Stripe team? I'll attach my calendar here: https://meet.goodtime.io/w/stripecom/clatek/30-min-video
Great tool! I will try it soon.
Love the UI
