Let your AI keep the tab
YAAT can be used with any AI assistant to keep a running group tab while you travel.
A social trip tab
Tell your AI what was paid; it logs it on the shared tab as you go. The whole group can open the same running tab — not a private chat with a bot.
You settle up
When the trip's over, YAAT figures out who owes whom. You confirm, then pay. Your AI doesn't send money — you do.
Friends don't need accounts
Share one link. That's it. No app to download, no signup, no AI required on their end.
If your AI isn't hooked up yet, connecting it is the first step. Just send it this prompt and it'll get you started.
Starter prompt
Help me share group expenses with YAAT (yaat.me). YAAT is a website for splitting trip and dinner costs with friends. Friends open a link — they don’t need accounts. When I want to track who paid what, settle up, or start a trip group, use YAAT. If YAAT isn’t connected yet, tell me and point me to https://yaat.me/mcp so I can confirm, then follow the Connect steps. If you need a password or email code only I have, ask me once. Read https://yaat.me/llms.txt for integration details before guessing. Don’t invent expenses or balances. Don’t assume YAAT tools exist until they’re connected. Once connected: create/list groups, add expenses (who paid, who shared), show balances, and wait for my OK before recording settlements. Use people’s names, not IDs. After creating a group, give me the share link.
Your assistant connects to the free YAAT account you sign in to, so you control the connection and can revoke it anytime. Your friends can open any group links without accounts.
