Is WKO AI really a free ChatGPT alternative?

Yes. Core chat is free and unlimited with no subscription. Open models like Qwen 3.5 run on your own device via WebLLM and WebGPU, so there is no paid tier required to keep chatting.

Do I need an account to use it instead of ChatGPT?

No. There is no sign-up, no email form, and no account to create. Open the chat, pick a model, and start typing — unlike ChatGPT, which requires an OpenAI account.

Can it replace ChatGPT for everyday use?

For private, unlimited local chat it can. You get message continuity, file knowledge via local RAG, and optional web search. Larger cloud models may still lead on some heavy reasoning tasks.

Does my chat data go to a server?

AI inference runs in your browser, so your prompts and replies are not sent to WKO AI. External web search is optional and uses your own provider key if you enable it.

WKO AI vs ChatGPT — private, unlimited, on your device

ChatGPT runs in the cloud, requires an account, and throttles usage — even on its $20/month plan. WKO AI runs open models like Qwen 3.5 in your browser via WebLLM and WebGPU, with local chat inference and optional external web search.
