Open ChatGPT
Navigate to chatgpt.com in Chrome. ChatCache activates automatically on this site — no extra steps required.
Open a conversation
Click any conversation in the sidebar to open it. ChatCache works with any conversation, regardless of length or content type.
Click the ChatCache icon
Click the ChatCache icon in your Chrome toolbar. If you don’t see it, click the puzzle-piece icon to open the extensions menu and find ChatCache there. The ChatCache popup opens and displays your export options.
Choose a format
Select the format you want from the popup. ChatCache supports 7 formats:
- Markdown — great for Notion, Obsidian, GitHub, and documentation tools
- HTML — renders in any browser, preserves full visual structure
- TXT — plain text, no formatting, compatible with everything
- PDF — typeset output with LaTeX formulas rendered pixel-perfect
- JSON — structured data, useful for developers and automation
- CSV — tabular format, easy to open in spreadsheets
- PNG — a screenshot-style image of the conversation
Each format has different strengths depending on your use case. See Export formats for a side-by-side comparison of all 7 formats and guidance on when to use each one.
