WindowAI

WindowAI is a ChatGPT tool. A browser extension and JavaScript library that lets web apps call the user's chosen AI model (OpenAI, Google, Anthropic, Together, Cohere, or a local model) without API keys or a backend, while logging message history for later training.

WindowAI is a browser extension and companion library that puts model choice back in the hands of users. Instead of every app negotiating its own API contract with a provider, the Window extension asks the user which model to call and handles the request on their behalf. Apps built on window.ai ship without a backend or stored keys, and the person browsing decides whether traffic goes to OpenAI, Google, Anthropic, Together, Cohere, or a model running locally. The product is aimed at two audiences. Developers get a small JavaScript surface through window.ai.generateText, including a streaming callback for incremental output, so a chatbot can be built with no server and no secret handling. Everyday users get one place to configure providers and switch between them as they browse compatible sites. The sample chatbot on the homepage demonstrates the pattern: it greets the visitor, accepts a typed message, and never asks for credentials because the extension supplies the model. In practice, the workflow is install the extension, open its configuration panel, and connect whichever provider accounts or local endpoint are preferred. From then on, participating apps call the installed model rather than a hardcoded one. The extension also records a history of messages sent and received, which the site suggests can be reused to train a custom model later. Local execution through LocalAI is presented as the privacy-oriented option for people who do not want prompts leaving their machine. Where it fits: WindowAI is less a chatbot and more plumbing between web apps and model providers, closer to a model router or identity layer than to a chat product. It competes with the usual pattern of each app bundling its own key and locking users to one vendor. The trade-off is dependence on a single browser extension becoming a de facto standard, and compatibility is limited to sites that deliberately integrate the library.
