Selective export
Choose Selected Messages and check the turns that matter. Full-thread export is still one click when you need the whole conversation.
Chrome extension for ChatGPT
Never lose a ChatGPT insight again
Turn conversations into clean Markdown, HTML, or TXT, export only the messages you need, and keep a local backup so code blocks, structure, and long threads survive the trip to your notes, docs, and repos.
Local-first. Exports run in your browser—no cloud processing for your conversation content.

FAQ
Quick answers
Is my data sent to your servers?
ChatCache is built around local processing in the browser for exports. Read the specifics in our privacy policy.
Which formats are available right now?
Markdown, HTML, and TXT are available now. PDF is still labeled as coming soon and should not be treated as shipped support yet.
Does it work with long or code-heavy chats?
Yes—fidelity for structure and code matters, and the tool is stress-tested for large conversations.
Where does ChatCache work?
The extension targets ChatGPT on the web (chatgpt.com and related OpenAI chat URLs). Check the Chrome Web Store listing for the exact permission scope.
How does Selected Messages work?
Choose Selected Messages in the popup and the extension will turn on message checkboxes directly in ChatGPT. Switch back to Full Chat and the page-side selector is removed.
