Overview

Fakturoid AI Agent is an AI-powered invoicing assistant for Czech freelancers and small businesses. It connects to Fakturoid — the most popular Czech invoicing platform and lets you manage invoices and contacts through natural conversation. No switching tabs, no filling forms. Just chat in Czech and the agent handles the rest.

The agent understands context across the conversation. Tell it to create an invoice for a client you just looked up and it won't ask for their ID again — it already has it.
