Overview

ChatGPT and Claude both support sharing conversations via public links, but neither provides a native way to export them as a portable file. Copy-pasting loses structure. Browser extensions require installation and permissions.

ChatToMD solves this: paste a share link, and the app fetches the conversation, parses it, and returns a clean .md file, ready to save, share, or reference.

Usage

1. Open a conversation in ChatGPT or Claude
2. Use the Share option to generate a public link
3. Paste the link into ChatToMD and select the source
4. Click Extract Conversation and download the .md file

⚠️ Only works with public share links. Only export conversations you own or have explicit permission to export.

How It Works

ChatToMD runs a headless browser in the background, loads the shared page, and intercepts the conversation data before it's rendered; no scraping, no fragile DOM parsing.
