Fork a response
Use the Fork control beside the part of a ChatGPT answer you want to explore.
Chrome extension
Fork any response into a side thread.
Ask follow-up questions without losing your main conversation. Explore a tangent, keep the context, and bring the useful result back when you’re ready.
Monthly AI limits: November 3, 2026 (UTC)
The unlimited monthly beta has ended. Free includes 25 AI generations per UTC calendar month; Pro includes 100. Hosted AI stops when the allowance is used. There are no automatic overage charges; local tools and saved history stay available.
Allowances reset at 00:00 UTC on the first day of each month. Existing usage is retained; upgrading, signing out or reinstalling does not reset it. Older Chrome Web Store wording about unenforced beta usage refers to the earlier beta period; its correction is awaiting review. Monthly limit details.
How it works
Fork → Explore → Apply
Keep your main conversation clean while you investigate details in a focused side thread.
2
Explore separately
Ask follow-up questions in a side thread grounded in the selected context.
3
Apply it back
When the side thread reaches a useful result, apply it back to your main conversation.
Apply to main chat
Bring the useful part back.
Explore freely without cluttering the original chat. Once you reach the answer you want, ChatGPT Fork lets you carry that result back into the main conversation.
History
Reopen saved forks anytime.
Fork history is stored locally in Chrome, so you can return to previous side conversations and manage saved forks from the extension.
Stay in flow.
ChatGPT Fork is designed for the moments when you want to ask “what about this?” without sending the entire conversation down a different path.
