Lavione

People who already pay for their own AI model access and want a simple chat window to use it will find Lavione a natural fit.

Lavione is an AI chatbot and text generator that runs on your own API key, so you decide which account and settings sit behind each conversation.

The interface is kept plain, and the chat can be adapted to different communication needs, such as drafting messages, rewriting text or working through ideas for writing and editing tasks.

The catch is the key itself.

Lavione requires you to bring your own API key, so it is not a tool you can open and use with nothing set up.

Usage costs come from whichever provider issued that key, not from Lavione.

The scope is also narrow.

Lavione works through chat only, and its answers are based on the content you provide in the conversation.

There are no extra modules for documents, images or automation.

If you want a focused, customizable chat layer for office writing and you are comfortable managing an API key, Lavione does that job without extras.
