Your AI categorizes the month. Every category posts a balanced entry.

Most tools put a label on a row. LedgerMCP posts a two-sided entry for each one and remembers where every merchant belongs. The few rows it is unsure about wait for you.

No card. Works with Claude, ChatGPT, Grok, Cursor, and any MCP client.

02 Categorize · bulk_categorize

Your AI assigns each row to a category from your chart of accounts, splits mixed charges, and books transfers as transfers. It remembers each merchant’s last category, so next time is one step.

03 Answer the flagged few · add_convention

Anything ambiguous stays flagged. Your AI asks, you answer in plain words, and it books the row and writes a rule from what you said. Corrections work the same way.

  1. The question

    DateMerchantDescriptionCategoryAmountReviewed
    06/18
    Pacific Cup Co
    needs review
    −$2,984.00

    One question: Pacific Cup Co, $2,984.00 on 06/18. Cups and lids, or equipment?

  2. Your answer

    Cups and lids. They’re our supplier.

  3. The rule

    Pacific Cup Co is our cup supplier. Book it as Cost of Goods Sold.

02 · The entry

A category is an entry, not a tag.

Behind every row, the bank account against the category.

The ledger refuses an entry that does not balance.

Categorizing posts both sides at once, so a wrong category is never an unbalanced book.

That is why a P&L from these books holds up with your CPA.

03 · The hard rows

Not every row is one category.

Each has its own tool, and each still balances.

  • SplitsOne charge, more than one category, one entry. The lines add up to the charge.
  • TransfersMoney moved from one of your accounts to another books as a transfer, not as money earned or spent. The $12,500.00 to savings on 06/20 matched its other side.
  • The owner’s own spendingA personal charge on the business card goes to Owner’s Draw, like the $8,766.00 on 06/28. The bank still ties.
  • BacklogMonths of statements categorize in bulk. Every row is its own entry, so one odd row never stalls the batch.

Questions

Common questions.

Can AI categorize my bank transactions automatically?

Yes. Connect Claude or ChatGPT and it categorizes each transaction against your own chart of accounts, one row or a whole month at a time. Under the hood every category posts a balanced double-entry journal entry, so the books stay correct, not just labeled.

Does it learn my categories over time?

Yes. LedgerMCP remembers the category each merchant was last posted to and suggests it next time, and that memory updates every time you correct something. You can also write durable rules, like a specific Zelle payment is always rent, that every future session follows.

How do I split a transaction across categories?

One charge can post across several categories in a single balanced entry, as long as the lines sum to the total. That covers a Costco run that was part groceries and part supplies, or a loan payment split into principal against the loan and interest as an expense.

What if the AI gets a category wrong?

Tell it, or fix it yourself in the app with one click. Nothing already in the books can be edited, so a correction reverses the old entry and posts a fresh one linked to it, never a silent edit. Your history stays complete, and the merchant is learned so it does not repeat the mistake.

Can I categorize a big backlog at once?

Yes. Bulk categorize was built for catch-up and migration: many transactions in one call, each with its own entry, so one bad row never blocks the rest. Most backlogs clear in an afternoon.

How are transfers between my accounts handled?

They are booked as transfers, never as income or expense, so moving money from checking to savings does not distort your P&L. LedgerMCP detects the likely matching leg and you confirm it; it never auto-matches on its own.

What about personal spending on a business card?

Categorize it to Owner’s Draw and the books still tie to the bank. The reverse case, a business expense you paid with a personal card, posts as an expense against Owner’s Contribution. Both keep the books honest without a second bank account.
