CtxPort Documentation

CtxPort is a browser extension that copies AI conversations as structured Markdown with one click. No data leaves your browser — everything is processed locally.

What is CtxPort?

When you work with AI assistants like ChatGPT, Claude, or Gemini, your conversations contain valuable context — decisions, code, ideas, and reasoning. CtxPort captures that context as clean, structured Markdown you can paste anywhere.

• One-click copy from inside any supported AI chat
• Sidebar copy without even opening the conversation
• Structured output with YAML frontmatter and Markdown body
• Multiple formats — Full, User Only, Code Only, Compact
• 100% local — zero data uploaded, ever

Quick Start

1. Download ctxport-chrome-mv3.zip from GitHub Releases 
2. Unzip and load it in chrome://extensions with Developer Mode on
3. Open any supported AI chat and click the copy button
4. Paste into your editor — structured Markdown, ready to go
