Local-first, runs locally
The product is designed for local/on-premise execution after installation. Technical exceptions such as activation, updates, support or KSeF connectivity are disclosed separately.
BezChmury was built on a simple observation: Polish businesses need AI, but they do not want to send their company data to US servers. We combine a local BezChmury 11B model + an SSoT knowledge base + a source-backed answer pipeline into one product: private AI compliance.
This is not marketing. These are the criteria we use to design every feature.

Every answer carries a deterministic citation: article, regulation, journal reference and effective date. You can verify each one.
Internal KSeF probe: 147/150 PASS on 150 control questions. This is a vendor metric, not an official MF benchmark and not a guarantee for every matter.
KSeF, VAT, JPK, ZUS, GDPR. This is not a general-purpose ChatGPT. It is an expert in Polish compliance.
Electron application + local BezChmury 11B model + SSoT knowledge base, trained on Polish corpora by SpeakLeash + Cyfronet AGH (ACK). Local mode is the default architecture; network exceptions require explicit configuration.
15 years with computers, the last 5 spent intensively on AI. Focus areas: fine-tuning, training, automation, local LLMs (BezChmury 11B), source-backed scoring, private RAG.
Tech enthusiast for 15 years - from web/SEO (ex-Villa Mamma) to product engineering. For the past 5 years exclusively focused on AI: language model fine-tuning, process automation, training pipelines, private deployments. Author of the entire KSeF Private pipeline - from fine-tuning BezChmury 11B on 41,000 training pairs, through the 630-fact SSoT, to the deterministic scoring layer and the FA(3) validator.
KSeF Private shipped in Q1 2026. The next modules expand the compliance scope.
FA(3) validator, error codes 410/440/450, 630-fact SSoT.
VAT/PIT/CIT, JPK_V7, ZUS pack, 2026 limits.
Generator for VAT/PIT/CIT declaration tables - free utility.
ROPA, DPIA, retention, incident workflows, local document analysis.
Full audit trail, policies, controls, reports.
Multi-NIP unlimited, license server, on-premise Kubernetes deployments.
After years of working with Polish businesses we kept seeing the same pattern - compliance questions about KSeF, VAT and ZUS are routine, but every SaaS answer travels to US servers. We built a local AI assistant for accountants, lawyers and CFOs - designed to run locally after installation, GDPR-aware, powered by the Polish BezChmury 11B model.
Bielik is a Polish open-weights LLM (developed by SpeakLeash and Cyfronet AGH ACK) - we can run it locally on the user's hardware. ChatGPT, Gemini and Claude all require sending data to US servers. Bielik gives us stronger control over the environment, reduced leakage risk, fine-tuning for KSeF/VAT/ZUS, and no per-query fee after the application is purchased.
The Bielik base model is Apache 2.0 (open-weights). Our domain-specific fine-tuning for KSeF/VAT/ZUS is the property of BezChmury (protected). The Electron application and the RAG engine are closed-source and licensed per seat.
First - local/on-premise architecture after installation rather than default SaaS. Second - every answer ships with a deterministic source citation. Third - hallucination risk is reduced through the 630-fact SSoT and source-backed answers. Fourth - one-time pricing, not a subscription.
Yes. The 15-minute demo is free, NIP optional. We only need a business email and consent to be contacted. The full privacy policy lives at /en/privacy.
For now we focus on Polish compliance only (KSeF, VAT PL, ZUS, JPK). Foreign companies with a Polish NIP (registered in Poland) are fully supported. The 2027 roadmap includes BezChmury EU (DACH compliance).
Yes - the Pro Bundle (PLN 14,900) includes 10 seats and a custom SSoT knowledge base, so you can add your own internal procedures. Enterprise (from PLN 49,900) removes the seat limit and adds multi-NIP support. We run a partner programme for firms with 50+ clients.
Every answer carries a source citation, so you can verify it. We also implement an "I don't know" mechanism - if a fact is missing from the SSoT, the model says "Not confirmed in the knowledge base" instead of hallucinating. This is a core product policy.
Email: dominik@bezchmury.app. Demo bookings: /en/demo. A direct phone line is shared after the demo (priority for Pro and Enterprise customers under SLA).
A short KSeF Private demo (15 min). We will show local execution, control questions, source base and how BezChmury reduces the risk of hallucinations.
