In-Chrome AI

A Google Chrome Extension that provides AI-powered suggestions for text input using Gemini Nano, Google's language model in the browser.

This project is only one of the many possible applications of Chrome's built-in AI capabilities. The extension is built using Deno and TypeScript. Read more on our Devpost submission.

Development

Install Deno: https://docs.deno.com/runtime/

Format the source code:

deno fmt

Generate Gemini API key (acts as a fallback solution when Gemini Nano is not available):

Update the .env file with the generated token:

GEMINI_API_KEY=""

Run the build command to bundle extension files in the unpacked directory:

deno task build
