Help me plan the launch of my budgeting app. Small team, $2k budget, 6 weeks.

Here's a 6-week plan that fits a $2k budget: - Weeks 1–3: waitlist page + 20 beta users - Weeks 4–6: Product Hunt launch + follow-up emails

Keep the budget split 60% ads / 40% content.

Done — $1,200 for ads retargeting the waitlist, $800 for two launch videos.

From ChatGPT to Claude in a few clicks

Say you planned a product launch in ChatGPT over forty messages and want Claude to turn the plan into a tight brief. You keep the goal, the budget decisions and the final plan, drop the brainstorming detours, and Claude starts from exactly where you are.

Doing it by hand

You can move the conversation yourself. It works, it’s just slower, and long chats are easy to get wrong.

Getting it out of ChatGPT

  • Select the messages you need and copy them, one reply at a time if the chat is long.
  • Or click Share to make a link to the chat. That's handy for people, but the other AI usually can't open it.
  • For everything at once, Settings → Data controls → Export data emails you a zip of your whole history, which is far more than one chat.

Putting it into Claude

Paste it into a new Claude chat. Long pastes show up as an attached block of text, which keeps the message box readable, and you add your next question underneath.

Questions people ask before installing

Will Claude know the conversation came from ChatGPT?

Yes. Relay starts the hand-off with "I'm continuing work from a conversation in ChatGPT", followed by the messages you chose, so Claude reads it as a continuation.

Can I bring only part of the ChatGPT chat?

Yes. Every message has a checkbox, and you can keep only the latest few. You see the full hand-off before anything moves.

Does Relay send the message to Claude for me?

No. Relay puts the text in Claude's message box and stops there. You read it, add your question and press send yourself.

Does my conversation go through Relay's servers?

No. Relay runs in your browser and has no servers. The text goes straight from the ChatGPT tab to the Claude tab.

What if the conversation is really long?

Relay warns you when a hand-off is very large, because a huge paste can make answers worse. Untick the side conversations and keep the messages Claude actually needs.
