Every AI you use starts from zero. Frogpost doesn't.
One key carries your chat, your rules and what's left to do into the next AI. You press send.
Try it: press G to grab, V to drop, Enter to send. Works in Claude, ChatGPT, Gemini and Gmail.
01 Why Frogpost
Your project, not your provider.
Chat apps each remember a little, and only inside their own walls. Frogpost carries your work between all of them.
Works with every AI.
Grab in Claude, drop in ChatGPT, Gemini or a Gmail reply. Or shape the same chat as an email, a Slack update or a task list for Cursor and Claude Code.
You're continuing work started by another agent. GOAL: ship v2.4 Friday. DONE: Safari CSV export fixed (synchronous click), 42/42 tests. DECIDED: build the orders index concurrently (final). DEAD END: Redis cache for exports, dropped: stale files. NEXT: 1) run the migration on staging 2) tag v2.4.
Also: TL;DR, task list for Cursor or Claude Code, or your own template.
Your rules, word for word.
A summary that drops a rule is worse than none. Your instructions are quoted exactly, with a source. Finished work counts as done only when the chat shows it was checked; the rest is marked claimed, not verified. Dead ends are kept. Any number, date or name that isn't in your chat is flagged for you to check.

API keys, tokens, emails and phone numbers are masked before a chat goes to our server, then put back on your computer. Your chats are remembered on your computer, and you choose which AI writes the handoff.
