01
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.
ABOUT US
Who we are
and why we build local AI
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.
MANIFESTO
Five principles, one product.
This is not marketing. These are the criteria we use to design every feature.
02
Cites its sources
Every answer carries a deterministic citation: article, regulation, journal reference and effective date. You can verify each one.
03
Limits hallucination risk
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.
04
Specialised, not general
KSeF, VAT, JPK, ZUS, GDPR. This is not a general-purpose ChatGPT. It is an expert in Polish compliance.
05
Polish model and Polish data
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.
TEAM
Dominik Witanowski - founder & CEO.
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.

ABOUT FAQ
Frequently asked questions.
Why did you build BezChmury?
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.
Why BezChmury 11B and not ChatGPT?
BezChmury 11B v1 is our Polish compliance LLM, fine-tuned on 41,000 training pairs from Polish tax law (KSeF, GDPR, ZUS, VAT, JPK). It runs locally on the user's hardware - data never leaves the device. ChatGPT, Gemini and Claude all require sending prompts to US servers and use a generic model that is not specialised for Polish law. BezChmury gives stronger control over the environment, reduced leakage risk, Polish specialisation and no per-query fee after the application is purchased.
What is the BezChmury license?
BezChmury 11B v1 and the desktop application are the property of the Service Provider - per-seat license, one-time purchase. Our domain-specific fine-tuning for KSeF/VAT/ZUS, the SSoT knowledge base and the RAG pipeline are protected IP. Open-source components we depend on (including the Bielik 11B base model under Apache 2.0 by SpeakLeash + ACK Cyfronet AGH, plus Python/Node.js libraries) are listed in the privacy policy under "Third-party components".
How are you different from Comarch or Symfonia AI?
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.
Can I see a demo without sharing my company NIP?
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.
Do you support businesses outside Poland?
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).
Do you partner with accounting firms?
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.
What if the model is wrong?
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.
How can I get in touch?
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).
Want to see private AI
for your business?
A short KSeF Private demo (15 min). We will show local execution, control questions, source base and how BezChmury reduces the risk of hallucinations.
