Polyfills for the built-in AI APIs like LanguageModel, Summarizer, and Writer. Built-in AI Extension — Polyfills for Web AI APIs

Bring the future of the web to your browser today. This extension enables experimental built-in AI APIs by injecting high-quality polyfills directly into web pages, allowing developers and enthusiasts to test and build with to-be-standardized AI interfaces before they are natively available in all browsers.

The extension injects polyfills into the main world (`window` object) at the earliest possible moment (`document_start`), ensuring that scripts on the page can seamlessly access them as if they were native browser features.

Supported APIs:

`LanguageModel` (aka. Prompt API): Interact with large language models.
`Summarizer`: Generate concise summaries of long texts.
`Writer`: Draft new content based on prompts.
`Rewriter`: Refine or rephrase existing text.
`LanguageDetector`: Identify the language of a given text.
`Translator`: Translate text between languages.

Key Features:

Multi-Backend Support: Choose your preferred AI provider! Connect to Google Gemini, OpenAI, or Google Firebase.
Local AI with Transformers.js: For ultimate privacy and performance, run models directly in your browser using Transformers.js.
Force Injection: Option to override native implementations, useful for testing polyfill behavior or ensuring a consistent experience.
Developer Friendly: Easy configuration of API keys and backend settings via the extension options page.

How it works: Sites that check for "window.LanguageModel" or "window.Summarizer" will find these APIs available. The extension proxies these calls to your configured backend, handling the heavy lifting of AI processing while you focus on the web standard implementation.

Note: This is a developer tool and experiment. Usage of cloud backends (Gemini, OpenAI, Firebase) requires your own API keys.
