Overview
Product summary
Review the store description, core capabilities, and common use cases.
Window is the simplest way to connect AI models to the web. Use a variety of models for text generation and 3D creations (new!).
FOR USERS: bring your own models to the web, including ones running locally. Set up your models once, and use them everywhere.
FOR DEVELOPERS: no need to pay for OpenAI or other language model APIs. Make model-agnostic & multi-media AI apps. Users can try them for free.
Configure your models once; after that, a web app can request your permission to send a prompt to your chosen model. You get visibility on what's being asked and when.
Discover Window AI apps with live usage metrics on https://openrouter.ai.
FOR MODEL PROVIDERS: access more users on the web, without needing developers to change their code.

An easier way to get local (any) models to "answer from this page instead". Goodbye Copilot Pro.
Not sure what's the point of this extension given the availability of fully open source alternatives. The only additional feature provided here is support for OpenRouter API, suggesting this extension is part of it. However after a quick test I've just found that OpenRouter needs a positive credit balance ($) to operate, even for the free to use models.
Started giving me unknown errors after working fine for a week. Can't figure out how to even get to their website to check an FAQ.
Window AI is great!
This is dope!
Building model-agnostic LLM apps is revolutionary and important. Additionally, it makes the developer experience for integrating large language models into apps easy and fast.
The user and developer experience is great! As a user, I can try many web apps without worrying about my API keys getting stolen, and can try different AI models. As a developer, I can reference the window.ai global variable to call the user's AI model.
If we're to have an LLM-connected internet, we can’t expect people to be pasting their keys into insecure text fields, and we can’t expect developers to front all inference costs. Window AI is the first real attempt at solving this problem.
