The Question That Started It

One random day, I found myself wondering

How many times do I actually open ChatGPT, Claude, or Gemini in a day?

Turns out I had no answer to that question. All I could do was make a few guesses.

I just wanted a simple way to see how often I was visiting these sites. And since I enjoy building things and love web development, my immediate thought was:

Why not build something that tracks it?

So I Built a Tracker

The extension after a few days of usage.

The idea was simple,

Every time I open:

  • ChatGPT
  • Claude
  • Gemini

the extension keeps track of it

No accounts. No analytics dashboard. No complicated setup.

Just a small counter running quietly in the background, answering my question

The Fun Part: The Heatmap

I didn’t want another boring table.

So I stole my favorite UI pattern: GitHub’s contribution graph.

GitHub's contribution graph.

Each day becomes a square.

The more AI sites I open, the darker the square becomes.

After a few weeks, the graph starts revealing patterns that would be difficult to notice otherwise.

Building It

The stack is pretty simple:

  • Chrome Extension (Manifest V3)
  • Vue 3
  • Chrome Storage API

Most of the challenge wasn’t coding.

It was deciding what should actually count as usage.

Why I Made It

Mostly curiosity.

I like measuring things.

Steps. Study hours. Coding streaks.

AI usage felt like another interesting metric.

Try It Out

If you’re curious about your own AI habits, give it a try.

You might discover that you’re opening ChatGPT a lot more often than you think.
