YUSYUS Ai
An AI coding assistant on your own key.
Sign up, paste the endpoint and API key you already have, and start asking your model for code. Three plans, daily message limits, and a transcript that keeps your work in one place.
No card required. Free plan includes 20 messages a day.
What an account gets you
- AssistantThis is a preview of the chat surface. The transcript, composer, and quota tracking are real — sign in to talk to the model this deployment is configured with.
How it works
Three steps, in the order you do them. There is no fourth.
01
Bring your own key
Paste the API key from your existing provider. It is stored against your account and never exposed to other users.
02
Pick a model
Chat with whichever coding models your key is entitled to. The model is set once on the account, not per message.
03
Start coding
Ask for code, explanations, reviews, or debugging. Replies land in the transcript, ready to copy into your editor.
