Books Builder

Build the categorization map first — before you touch a single statement. Feed it last year's categorized books (or one fresh statement) and it drafts your chart of accounts and vendor rules, then an AI accountant reviews every account: business vs personal, what's a real deduction, what's just a transfer — and flags the few judgment calls that actually move your taxes, biggest dollars first. Save the map, then reconcile a whole year in minutes. Your numbers never leave your browser.

The mapping is the product. Build it once, well, with an accountant's eye — then every statement after is just a file drop. Only short text descriptions + totals are sent for the review — never amounts per line, never the file.

🔒 What this touches: your file is parsed in your browser and never uploaded. For the AI accountant review we send only short text descriptions and per-account totalsnever amounts per line, never dates, never the file. The mapping you build lives in this browser only; export it to keep it.

Why build the map first

Last year's pain wasn't reconciling — it was building the categorization reactively: run the statements, see what's wrong, fix one transaction, run again. The map is the real asset, and you were discovering it after the fact.

This flips it. You already have a year of decisions sitting in last year's books — so we mine your own chart of accounts and vendor rules out of it, then put an accountant's eye on the handful of calls that change your tax outcome: what's personal, what's a transfer (not a deduction), which income is a separate schedule. Decide those once, up front. Then reconciling is just dropping files.

Learns from your real historyYour categories, your vendors, your business lines — extracted from how you already did it, not guessed from a template.
An accountant on the judgment callsBusiness vs personal, deductible vs transfer, ranked by dollars — so the big calls get attention and the small ones don't waste yours.
