5-hour and weekly limits
How much of each window is left and when it resets, in your local time.
Check your Codex usage limits and reset credits.
AI Limits Tracker reads the Codex limits of your ChatGPT account straight from OpenAI — the 5-hour and weekly windows, the percentage left, the exact reset time, and any reset credits you can spend.
Free with one connected account. iPhone (iOS 17 or later), Apple Watch, Mac menu bar, and Android.
Codex usage
Every Codex limit, one glance away.
Extra pools such as Spark
Additional Codex limits appear as their own named rows instead of being hidden.
Reset credits
Each available reset credit with its expiry time — and you can spend one from the app, with a confirmation, when a limit runs dry.
Expiry and limit alerts
Reminders 5 hours and 1 hour before a reset credit expires, and a notification when the weekly limit falls to your threshold.

FAQ
Codex usage, answered.
How do I check my Codex usage limits?
Connect the ChatGPT account you use for Codex in AI Limits Tracker. The 5-hour and weekly limits appear with the percentage left and the reset time, together with any extra pools such as Spark.
What are Codex reset credits?
Credits that reset your Codex limits before their scheduled time. The app lists each one with its expiry time, reminds you 5 hours and 1 hour before it expires, and lets you spend one after a confirmation.
When does the Codex usage limit reset?
Each window has its own reset time. The app shows the exact time for the 5-hour and weekly limits in your local time zone, and notifies you when a limit resets — including early resets.
Does it work with ChatGPT Plus and Pro?
It works with the ChatGPT account you use for Codex and shows whichever limits OpenAI reports for your plan.
Does GPT-6 Astra have its own Codex limit?
No. GPT-6 Astra draws on the same Codex 5-hour and weekly limits as the other models, and a heavy model like Astra can use them up faster. AI Limits Tracker shows those limits, so you can see how much room Astra has left before you start a long task.
