Free Chrome extensionCopy a complete Gmail thread for AI.
Turn the conversation open in Gmail into clean, structured text for ChatGPT, Claude, Gemini, or another AI. Keep every sender, date, message boundary, link, table, signature, and attachment in context.
Free to use. No Google OAuth. No extension account. No automatic AI upload.
Local processing
The extension prepares the thread in your browser.
No OAuth
It uses the Gmail session already open in Chrome.
You choose the destination
Nothing is sent to an AI service automatically.
How it works
Install once. Copy in Gmail. Paste anywhere.
The workflow takes three steps and does not require a separate login, API key, or connection to an AI provider.
- 01
Install in Chrome
Add the extension from its official Chrome Web Store listing.
- 02
Copy the open conversation
Choose Copy thread, Copy plus save files, or a configurable keyboard shortcut.
- 03
Paste where you choose
Put the structured text into an AI prompt, document, ticket, or project handoff.
Why not normal copy and paste?
A thread can look complete while missing context.
Copying the visible Gmail page can omit collapsed messages, repeat quoted history, flatten tables, lose links, and separate attachments from the messages that carried them.
Read the complete copying guideComplete conversation context
The extension requests Gmail's full view of the open conversation, including messages that may be collapsed on the visible page.
Clear message attribution
Every message keeps its sender, recipients, date, body, signature, and attachment context so an AI can tell who said what.
Warnings you can act on
If Gmail returns an uncertain or partial capture, the copied document includes field-specific warnings instead of pretending it is complete.
Useful structure for AI
Links, lists, tables, message boundaries, and bounded text attachments become readable Markdown inside a strict XML envelope.
Designed for honest captures
It tells you when a thread needs review.
Copy Gmail Thread for AI verifies the conversation identity and records message, header, and attachment completeness separately. Unknown values stay unknown instead of being guessed.
Privacy by design
Your thread stays local until you paste it.
The extension has no publisher server, analytics, telemetry, ads, remote code, stored account, Google OAuth flow, or API key. It reads Gmail only when you choose a copy action.
Email and attachment text can still contain sensitive information or prompt injection. Review the capture before sharing it or asking an AI to act on it, especially in high-stakes work.
What you can do with it
One clean thread. Better answers.
The extension does not summarize or write replies itself. It gives the tool you already use a more complete, reviewable source.
Draft a complete reply
Give your AI the full history, then ask it to answer every open question without repeating points that were already resolved.
Summarize a long thread
Extract the timeline, decisions, disagreements, owners, commitments, and next actions from one reviewable source.
Prepare a handoff
Turn a client, vendor, recruiting, or project conversation into context another person can understand quickly.
Review commitments
Ask what each participant requested, promised, rejected, or left unresolved, with message-level attribution.

Does the extension connect ChatGPT to my Gmail account?
