Overview
Product summary
Review the store description, core capabilities, and common use cases.
ChatGPT limits the number of messages you can send to certain models (gpt-5, gpt-5-thinking) over certain periods of time.
The ChatGPT UI tells you when you’ve exceeded your quota, but doesn’t tell you exactly how many messages you‘ve sent.
This extension tracks how many messages you‘ve sent to each model over a period of time — one week gpt-5-thinking; and three hours for gpt-5, to help you judge how close to the limit you might be.

I believe the cap is now at 20 messages, yet the extension is still showing 40.
I will give a five for it's utility, but I would like to notify that it suddenly stopped working. After simply deleting and re-installing, it worked again, but just to let you know there are some bugs with this extension
it can not track when using explore GPT
Great extension, it works seamlessly and the counter on extension icon & bar charts are really cool. It can also distinguish between 3.5 vs 4, which is really helpful. Great Work. Thanks for creating this.
This should be an inbuild function, but this extension does exactly what you need it to do. This way, you always know how much messages you have left. Perfect. Had a bug, messaged the dev, he fixed it in less than 3 hours. Outstanding.
Very useful and the developers are quick to update when ChatGPT gets an update. One thing I'd suggest is making a version for Firefox users.
Great extention, but sometime the counter isn't correct I didn't use chatgpt since yesterday but today chatgpt says i reached the limit but the extention still shows 19 ( I kinda believe the extention over chatgpt) as a solution can you add a reset botton in case I used chatgpt somewhere else, for example when clicking on the botton it sends a message in chatgpt if the returened message is "Limit reached" reset the counter to 0. Thanks
does not work, very inaccurate for me (example: number 18 displayed, but cap reached.). frustrating
@Josh Staiger hey brother dev, I have a question. Will this extension track the usage of other people on the account? I needed that the most. The app works good so far.
Works exactly as advertised so far. Having the counter in the extension's icon is great.
