One-Time Chrome Setup

To use Gemini Nano in your browser, you’ll need to adjust three experimental Chrome flags. These allow Chrome’s Prompt API and on-device models to function:

chrome://flags/#optimization-guide-on-device-model → Enabled (BypassPerfRequirement)

chrome://flags/#prompt-api-for-gemini-nano → Enabled

chrome://flags/#text-safety-classifier → Disabled

Will it work on my machine?

Please find the system requirements here: Gemini Nano System Requirements

Chrome’s Prompt API Is Experimental

Because TagChoose uses a Chrome Origin Trial (Prompt API), it is subject to change. You may need to re-enable flags, update Chrome, or reinstall the extension in future releases.
