AI built into the workflow
AI that acts on your real financial data
Not a generic chatbot — each AI feature operates inside a specific workflow and grounds its output in your actual numbers.

When a pipeline stage is waiting for your approval, AI generates a personalised Polish email for that escalation stage. You review, edit, and send.
KSeF anomaly detection
After every KSeF sync, new invoices are automatically analysed for unknown sellers, amount spikes, and potential duplicates. Results appear as coloured badges on each invoice row.
Accountant narrative
One click generates a 200–350 word professional Polish summary of your year-to-date finances — regime changes, anomaly counts, and notable months — ready to attach to your accountant export.
