The projects

What you give up either way

  • Invested brand and existing user base (millions of conversations)
  • Polish-language tuning and any proprietary prompt tuning or curated persona data
  • Operational scale, reliability and optimisations accumulated in production
  • Polish UI/UX polish, analytics and user-satisfaction tuning

An open-source project doing the core job proves a replacement is possible. It does not prove it matches Czat.ai, and it does not prove anyone has run it for a month. How we decide.
