Netresearch Browser AI adds a frontend question-and-answer dialogue grounded in
content of the currently open page. Chrome 148 or newer runs Gemini Nano on
the visitor's device through the built-in Prompt API.

The proof of concept has no application LLM endpoint, no chat persistence and
no telemetry. A provider boundary is ready for later page-tree or whole-site
context, but the implemented scope is deliberately the current page only.

> [!TIP]
> A running demo is available at [netresearch.github.io/t3x-nr-browser-ai](https://netresearch.github.io/t3x-nr-browser-ai/). It serves the
> distributable bundle and answers from the demo page's own content. Browsers
> without an on-device model see the fallback instead, which is the same path
> a visitor takes on a production site.

> [!IMPORTANT]
> Browser built-in AI availability depends on Chrome, the desktop platform,
> hardware, storage and model state. Always configure an appropriate fallback
> or choose explicitly to render no fallback.
