Window AI is a browser-based approach to using AI models directly inside web applications. Instead of the developer picking a single provider, the user chooses the model, while the app calls window.ai and connects through a browser extension.
How it works
Developers add simple client-side calls (for example, generateText) and can receive streaming responses without running a server backend or storing API keys. This makes it easier to prototype chatbots and other AI features that run entirely in the browser.
Who it’s for
Window AI fits teams that want to add AI to a web UI quickly, reduce the risk of handling API keys, and give users control over which model they use.
Typical use cases
- Rapid prototyping of AI features in web apps
- In-browser chat and text generation with streaming output
- Building AI-enabled sites without managing keys or backend infrastructure
Users install the extension once, and compatible websites can then work with the model the user has selected.
