Start in ChatGPT.
Continue in Claude.
Or the other way round. ContinueChat packs up the conversation, opens the other assistant and fills in the message box for you — you just read it and press send. Plus folders, pins, search and export, all kept in your browser.
Switch assistants without starting over.
One answer stalls, the other might nail it. ContinueChat carries the conversation across so you don't have to copy, paste and re-explain.
Click Continue
Open any chat on chatgpt.com or claude.ai and press Continue in the ContinueChat panel.
Choose how much to bring
The last 4, 8, 12 or 20 turns — or all of it — trimmed to fit, without ever cutting a code block or table in half.
Review and send
The other assistant opens in a new tab with the message box already filled in. Edit if you like, then press send yourself.
A tidy home for every AI conversation.
ContinueChat adds a small panel to the sidebar of both sites. Everything it stores stays on your computer.
Continue across assistants
Hand a conversation from ChatGPT to Claude or back, with attachments' text included and a size budget you control.
Folders and pins
Group chats by project, pin the ones you come back to, and keep both sites' chats side by side in one list.
Search that actually finds it
Instant local search over titles and the full text of chats you've opened — including Chinese and Japanese words mid-sentence.
Export to Markdown, JSON or PDF
Save a chat with code blocks, tables and lists intact. Back up everything to one file and import it again anytime.
Private by design
No account, no analytics, no servers holding your conversations. Delete all local data from Settings with one click.
English and 简体中文
The interface follows your browser's language, and the context it writes follows the language you choose.
Free to start. One small upgrade if you live in both.

Questions, answered.
Does ContinueChat send messages for me?
No. It fills in the message box on the other site and stops there. You read it, change it if you want, and press send yourself. If the box can't be filled, you get a "Copy context" button instead.
Where are my chats stored?
Only in your browser. There is no account and no server that stores your conversations, and there are no analytics. The one network request ContinueChat makes is to check a Pro license key. Details are in our Privacy Policy.
What counts as a "continue"?
Each time ContinueChat opens a chat on the other assistant with your context filled in. The Free plan includes 3 per month and resets on the 1st. A continue is only counted when the new tab actually opens.
What happens if my Pro plan ends?
Nothing is deleted. Your chats, folders and pins stay exactly as they are; only Pro actions (more continues, new folders past 5, bulk Markdown/PDF export) are locked until you renew.
How do I cancel or get a refund?
Cancel Pro Monthly anytime using the link in your Creem receipt email — you keep Pro until the end of the period you paid for. Within 14 days of your first purchase, email help@coylin.com for a full refund. See the Terms for details.
Is ContinueChat made by OpenAI or Anthropic?
No. ContinueChat is an independent product made by CoyLin Studio. It is not affiliated with, endorsed by or sponsored by OpenAI or Anthropic.
Which browsers are supported?
Google Chrome 116 or newer on desktop. Other Chromium-based browsers such as Edge and Brave usually work, but we don't officially test them yet.
