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.

Although not the prettiest looking extension, it does the job!
Please add 5.1-thinking
plz update it for chatGPT new update.
please add support for chatgpt 5
One less extension to make.
Very useful but doesn't add messages when you re-generate the response using "Switch model". Would be much-much better if you would be able to add to the counter manually
Great Extension, works as expected. Eagerly waiting for o3 update. My weekly counters for o1 reset at a certain time every week. It would be nice if instead of manually resetting this every week - I could set this day of week/time and it would automatically take care of it.
Excellent extensions, it works great!
Doesn't work with /reason for o1 model, thinks that it's a 4o prompt. Counts if the full chat is in a given model.
Great product. Would be 5/5 if the counter would be always displayed somewhere on my screen whenever I'm using ChatGPT. Having to click on the extension every time does not keep me up to date as well, since it depends on me remembering to check.
