I Built a Chrome Extension That Auto-Replies to Tweets Using Gemini AI

Wanted to share a side project I’ve been building.

It’s a Chrome extension that:

  • Reads your X/Twitter timeline
  • Uses the Gemini API to analyze each post
  • Generates replies automatically
  • Posts them on your behalf
  • Repeats this for 15 posts

Why?

To automate engagement and help creators stay consistent.

The tool uses:

  1. Manifest V3
  2. Content scripts controlling DOM + input
  3. Gemini 1.0 API
  4. A custom system prompt for tone control

Upcoming features:

  • Scheduled posting
  • Auto-posting tech news from free APIs
  • Smarter rate limiting + safer automation
  • Video demo attached. Would love thoughts from the dev community!
