Odd Bits
An applied product of Navital Labs.
Small tools that open your files in your own browser, and plain-file kits for people building with AI.
Many free file tools on the web start by uploading the file to a server: a chat export, a photo with its location still inside, a PDF with a name that has to go. After that, the person using the tool can't see where the file went or what was kept.
Each Odd Bits tool reads the file into memory in the browser tab, works out the result there, and drops it when the tab closes. The kits are Markdown and code files to download, so they can be read in full before anything in them is used.
The site is a static Next.js export on Cloudflare Pages, with no server that accepts files from a tool. A build step writes the headers for every tool page, including a Content Security Policy of connect-src 'self'. PDF Redactor reads pages with pdf.js and draws each redacted page again as a picture with the boxes painted in, so the text under a box is not in the saved file.
What is Odd Bits?
Odd Bits is a Navital Labs site with 14 products: 10 free tools that run in your browser, including Year in review, Privacy Leak Check and PDF Redactor, and 4 downloadable kits for people building with AI tools.
Where does my file go when I use a tool?
The tool opens your file inside your own browser tab and works on it there. Tool pages are served with a Content Security Policy that only lets their code talk to oddbits.tech, and the site's "How your files stay on your device" page shows how to check this in your browser's Network tab.
What does Odd Bits cost?
All the tools are free to use. The four kits are $9.99 each and go on sale soon; at first they are sold by email: you write in, pay a USD invoice through Wise, and the files arrive by email.
What are the kits?
Plain files for people building with AI tools: a setup for running several Claude Code sessions as a small team, a tested remote MCP server with OAuth, five templates for fixed-price work, and read-only SQL checks for common Supabase data-exposure mistakes.
First released on 19 October 2026 with 14 products: 10 tools that run in the browser and 4 plain-file kits. The first piece was Year in review for WhatsApp chats; the store, the other tools and the kits grew around it.
