Why ChudoII
Why I built ChudoII
I built ChudoII because I got tired of bouncing between ChatGPT, Claude and Gemini. Each has its strengths, but there's no single place to ask them all and compare answers.
ChudoII is a Russian-first solution: data stays in Russia, payment in rubles, and you can keep chatting without internet through on-device Gemma 4 E4B.
We pull the world's best models into one interface — with smart fusion, side-by-side streaming and 152-FZ privacy. One prompt, four perspectives.
