   Ask your AI about your money

   Your AI can now read transactions, balances, and spending patterns. Just ask. Example FoodSubscriptionsTrend You How much did I spend on food last month? openfinance · query_transactions Your AI You spent $847.32 on food last month.
   • Restaurants & dining $412.50
   • Groceries $389.22
   • Coffee shops $45.60 That is 12% more than the month before.

• Use your own AI

  Works with Claude, ChatGPT, Codex, Cursor, OpenClaw, or any AI that supports Skills or MCP. No lock-in, no middleman.

• Read-only access

  Your AI can read your accounts and transactions. It can't move money or change your accounts.

• Completely open source

  No tracking, no analytics, no hidden fees. Read every line of code yourself.

• We don't use your data

  Data syncs so the product works, but we never sell it, train on it, or use it for anything else.

• Always up to date

  Transactions sync automatically so your AI always has the latest picture of your finances.

• Hosted or self-hosted

  Use the hosted app, or self-host it and point your AI at your own server.
