## The prompt

    Propose categories for these uncoded transactions: [paste date, payee, amount rows]. Follow these past coding examples: [paste]. Per row: proposed category, the evidence, confidence. Mark anything under 70% confident as REVIEW. Proposals only - do not post anything.

## What to bring

Uncoded transactions pile up all month, and categorizing them means reading payee strings and trying to remember how you coded the same vendor last time.

## What a good run returns

A category per transaction with the evidence behind it, in a Google Sheet in a Bookkeepers Transaction Categorization Workspace folder.

## Where the free version ends

A prompt runs when you remember to run it, from whatever context you paste, and it forgets the rules between sessions. The [Transaction Categorization Agent](/bookkeepers/transaction-categorization-agent/) ($19 one-time) installs this as a standing workflow: fixed evidence rules, a saved output in your own Drive every run, fictional-data testing before real work, and hard stops before anything sends, spends or publishes. More detail on the [AI transaction categorization guide](/agents-for/bookkeepers/transaction-categorization/).
