Web polyfill

Not all browsers support the on-device AI APIs, so when AiBrow is installed and those APIs are unavailable, it automatically polyfills these fields. The API should provide the same level of compatibility as the native built-in APIs, and the user will be guided to complete the extension install at use.

If you want to check if the APIs have been polyfilled, you can check the aibrow property on each:

window.LanguageModel?.aibrow === true // aibrow has polyfilled window.LanguageModel
window.LanguageDetector?.aibrow === true // aibrow has polyfilled window.LanguageDetector
window.Rewriter?.aibrow === true // aibrow has polyfilled window.Rewriter
window.Summarizer?.aibrow === true // aibrow has polyfilled window.SummarizeruageModel
window.Translator?.aibrow === true // aibrow has polyfilled window.Translator
window.Writer?.aibrow === true // aibrow has polyfilled window.Writer
