What it does.

Zettl connects Czech bank transactions to invoices and receipts. You sync your accounts, drop in documents (or let it pull them), and it pairs lines with AI-assisted matching — so unmatched transactions stay visible and matched ones stop nagging.

Who it's for.

Freelancers and small businesses that need a single place for cash flow, documents, and audit-friendly exports — not a generic "ERP" with three modules they'll never open. Czech-first: built around the banks and accounting habits people here actually use.

What makes it different.

Strong dark, data-dense UI — the kind that respects your eyes after the third hour. Multi-bank Czech connectors and AI extraction/matching aren't bolted-on; they're the technical spine. Documents are first-class, not attachments.

FIG 02 — Signature detail

Multi-bank Czech connectors and AI extraction aren't a decorative add-on — they're the technical spine of the product.
