StatementKit

Deterministic bank statement normalizer for AI agents and bookkeeping tools: CSV from any bank, camt.052/053/054, MT940, OFX/QFX and QIF in; normalized JSON, analysis and CSV/hledger/SIE4 export out.

Built for agents and bookkeeping tools that receive statements in a dozen shapes: send the file as text, get one consistent schema with signed amounts, ISO dates, counterparties and balances. Analysis finds monthly totals, recurring payments, suspected duplicates and checks that opening balance plus transactions equals closing balance. No AI is involved and nothing is stored.

Honest notes

Parsing is deterministic heuristics, not bank-certified. Always check the result, especially CSV column and date detection (see warnings).
Ambiguous dates (01/02/2026) and decimal separators are guessed per file; the choice is reported in meta and warnings.
Analysis (recurring payments, duplicates, counterparties) is heuristic: duplicates are suspected, never removed.
SIE4 export is experimental. Verify account numbers before importing it into bookkeeping software.
The free rate limit is best effort: it lives in the memory of one Worker isolate and can reset.
No PDF, no OCR, no image support.

Privacy

Documents are processed in memory and never stored or logged. Logs contain only the operation, the detected format, sizes and error codes. There is no database. Payments are verified and settled by the x402 facilitator.
