1. Short summary (max 132 chars)
Convert webpages and AI chats into clean Markdown. All local, no sign-up. Code blocks, tables, and language tags stay intact.
2. Detailed description
Quilldown converts webpages and AI chat conversations from ChatGPT and Claude into clean Markdown. It is built for developers, researchers, and writers who paste content into LLMs or keep notes in Markdown and want the source formatting to survive the trip.
The conversion preserves structure that other tools drop. Code blocks keep their language tags. Tables convert to GitHub Flavored Markdown, and when a table is too complex for GFM it falls back to HTML instead of losing data. Nothing is truncated, no matter how long the page or conversation is.
Everything runs on your machine. There is no account and no sign-up, and no page content ever leaves your browser. The only network request Quilldown makes is a one-time license check when you activate Pro.
It works on Stack Overflow, Wikipedia, arXiv, documentation sites, articles, and most other pages you read.
The free tier covers 5 conversions per day. Pro is a one-time $15 purchase that removes the daily limit and adds AI chat export for ChatGPT and Claude conversations.
3. Permission justifications
activeTab: Reads the content of the page you are currently viewing when you trigger a conversion, so Quilldown can turn it into Markdown.
storage: Saves your settings, daily conversion count, and Pro license status locally on your device.
scripting: Injects the script that extracts and converts the page content into Markdown when you run a conversion.
Host access to getquilldown.com: Used only for the one-time license check that activates Pro.
Host access to chatgpt.com and claude.ai: Lets Quilldown read ChatGPT and Claude conversations so it can export them as Markdown.
4. Category recommendation
Developer Tools. The core users are developers moving code and technical content in and out of Markdown, and the feature that matters most, preserving code blocks with language tags, is aimed squarely at them.
