See where your money goes, starting from a bank CSV.
Transactions are sorted by rules you can edit, subscriptions and unusual charges are flagged, and budgets and savings goals are tracked month by month. Only category totals are ever sent to the model.
The app itself, running inside this page. Anything you do here is saved in your browser.
Ask it to do things
Press Ctrl+K in the app (Cmd+K on a Mac) and describe what you want. The model chooses from the app's own functions, runs them in order and tells you what changed. Some examples:
| Set my dining budget to 300 and groceries to 450 | Updates both monthly budgets. |
| Anything containing UBER is transport from now on | Adds a categorization rule and reapplies it. |
| What did I spend the most on last month? | Looks up the month's category totals and answers. |
Instructions you save in the same box, such as "keep it short" or "I'm a beginner", are added to every AI request the app makes.
