AI Transaction Categorizer

Label every payment in a bank statement (groceries, transport, bills and more) with a small AI model on your device.

Free, no uploads, no sign-up. Runs 100% in your browser.

How AI Transaction Categorizer works

Bank files and numbers are read and worked out in your browser. Nothing is uploaded, so account numbers and spending stay on your device. The AI mode compares the meaning of each payment text with your category list using MiniLM sentence embeddings (Transformers.js) in a Web Worker. Keyword rules run first for well known names, and Quick mode uses only the rules, with no download.

Input: OFX, QIF, XML, STA, CSV. Output: CSV, XLSX, QIF, JSON.

How to use AI Transaction Categorizer

Drop a statement.
Edit the category list if you like.
Press Label and wait for the model (25 MB, once).
Fix any label in the table and download.

Tips

Bank files hold account numbers, so tools that run on your device are the safe choice.
Always compare totals with the original statement before you file anything.
OFX and QIF files import into most money apps.
