Any webpage to clean Markdown.·minibase.md

Minibase is a Chrome extension that converts any webpage into clean, structured Markdown with one click, using AI-powered content extraction to strip ads and clutter. It includes Minibase Vault, a free local knowledge-base app for Mac and Windows that stores saved pages as Markdown files and can connect to Claude or ChatGPT via MCP. A paid Minibase Plus tier adds AI templates, saved history, and video transcription, and a separately offered Save API lets developers convert URLs to Markdown programmatically.
