The component when not supported by the browser, will fall back to server LLM or behave as a regular component (Function as usual).

Observations
Following our recent(31st October 2025) observations, we noticed that: - Microsoft Edge: We noticed that Microsoft Edge version 142.0.3595.65 also supports the same APIs Provided you enable them using edge://flags (Type this in your browser address /URL bar, search for the keywords and enable them): Translator API, Summarizer API, Writer API, Rewriter API, Prompt API, and Proofreader API, but not Language Detector API. Future updates might fix this. Let us know if you found a workaround.
Note
For cases where language detection is not supported, we have used tinyld library to detect language. Example, arch.
Note: These APIs are Chrome-specific and require Chrome 138 or later. For more information, visit the Chrome Built-in AI APIs documentation.
