Our verdict

Window AI connects your own AI models, cloud-based or running locally, to web apps that request permission to send a prompt, covering models from OpenAI, Google, Anthropic, Cohere, and local options like Llama. It's built for developers who want to build AI features without paying for API access themselves, and for users who'd rather bring their own model than depend on one vendor. Everything depends on configuring a model first, permission has to be granted per app request, and 3D generation currently covers only OpenAI's Shape-E.

✓What it does well

Bring your own modelConnects models you already have, including ones running locally, to any web app.

✕Where it falls short

Setup required firstNothing works until you configure a model, not a plug-and-play experience out of the box.
Per-app permission neededEach web app needs your permission before sending a prompt, not a one-time blanket approval.
3D generation is narrow3D object generation currently supports only OpenAI's Shape-E, not a wider range of 3D models.
