PROBLEM

Businesses need AI,
but they cannot take risks.

KSeF, JPK, VAT, ZUS and corporate documents demand precision. A public chatbot answers fast - but offers no:

Source control
You don't know where a public model gets its facts. BezChmury cites article numbers, journal references, and SSoT fact_ids.
GDPR compliance
Client documents never leave your computer. Everything stays on-premise. RODO is the Polish equivalent of GDPR - both apply here.
Audit trail
File hash, query log, who-asked-when trace. Ready for ISO 27001 audits.
Up-to-date knowledge
Annual update pack with controlled SSoT - the model knows exactly what you uploaded, no more, no less.

BezChmury solves this with local execution + a private SSoT knowledge base + deterministic source citations.
