WebLLM · 100% in-browser
Free AI chat, no sign-up — with local inference
Most "free" AI chats hand you a login form, a message cap, or both. WKO AI runs open LLMs like Qwen directly in your browser with WebLLM and WebGPU. Your chat content stays local unless you enable an external search provider.
Why it's different
Free means free — and private means private
-
Truly no sign-up
No email, no account, no "free trial" gate. The chat is ready the moment the model loads.
-
Private by architecture
The LLM runs on your device via WebLLM and WebGPU. AI content stays local unless you enable an external search provider.
-
No message limits
No daily cap, no throttling, no queue. Chat as long as your browser tab is open.
-
Free forever
Open models, cached in your browser after a one-time download. Nothing to subscribe to.
More than a blank prompt
Local documents and voice, with search when you choose
-
PDF knowledge (RAG)
Drop in a PDF and the chat answers from it — parsed and embedded locally, page by page.
-
Optional web search
Bring your own API key to let the assistant pull in live web results when you want fresh answers.
-
Voice mode
Speak your prompts and hear replies with local Whisper transcription and Kokoro TTS.
Questions
Frequently asked questions
-
Do I need to sign in or create an account?
No. There is no sign-in, no email form, and no account to create — the chat is ready the moment the model finishes loading in your browser.
-
Is the chat really unlimited?
Yes. Because the model runs on your own device, there is no daily cap, no throttling, and no queue — you can chat for as long as the tab stays open. See how this compares to ChatGPT.
-
Which LLMs can I chat with?
Open models such as Qwen and SmolLM2, running locally through WebLLM and WebGPU. You pick the model in the chat; the larger ones need a WebGPU-capable GPU.
-
Does it work offline?
Yes. The model weights download once and are then cached in your browser, and may support offline use once all required assets are cached. Test the tool before disconnecting.
