Fix a miscategorized expense (and teach Vault)
Correct a category once and Vault's on-device model learns it for next time.
Vault guesses categories automatically, and it gets smarter the more you use it. When a category is wrong, fixing it takes a tap and quietly trains the app to your habits.
- 1
Open the expense
Tap the transaction with the wrong category.
- 2
Change the category
Tap the category and choose the right one.
- 3
Save
Your correction is saved and applied right away.
Vault uses an on-device machine-learning model that learns from your corrections. Fix a merchant once and similar transactions are more likely to land in the right category next time.
The category model lives and retrains on your device. Your corrections, merchants, and amounts are never sent anywhere to improve it.
