What is Minibase?
Minibase is a browser extension that converts any webpage, video, or article to clean Markdown with one click. It works across 300+ popular sites — from Twitter threads and YouTube transcripts to Amazon products and GitHub repos.
Install Minibase Vault, the free companion app for Mac and Windows, and every page you save is automatically stored in a local knowledge base on your computer. Organize your saves into topics, and your knowledge library grows as you browse.
Connect Minibase Vault to Claude or ChatGPT, and everything you've saved becomes instant context for your AI. It can search your knowledge base, reference your saved articles, and give you answers grounded in what you actually read — not just generic training data.

Why I built Minibase
I use it every day. Here's the problem it solves.
“I chat with AI all day, and Markdown is the format AI understands best. Your AI doesn't know what you read, what you watched, what you bookmarked. I built Minibase to change that.”
