See your Claude and ChatGPT usage at a glance
Plans for Claude and ChatGPT come with limits, and the first sign of one is usually a message saying you have hit it. Prompt Petal Pro shows how much of your plan is used before you get there, in the corner of your screen where you can glance at it.
What the meter shows
The meter covers your Claude plan and your ChatGPT plan, including Codex. It shows how much of each is used for the next few hours or for this week, and when the limit resets. You choose which view you want.
On a Mac the meter sits in the menu bar. On Windows and Linux it sits in the tray.
Pick the look you like
The default look is your flower. It loses one petal for every 20 percent of the plan used, so a full flower means plenty is left and a bare center means the plan is nearly gone. If you prefer something else, choose a battery, a bar, a percent number, a circle or a dot.
Turn it on
- Open Prompt Petal Settings: the AI tab on a Mac, the General tab on Windows and Linux.
- In the AI usage section, switch on Show my AI usage.
- Pick the look and whether to show the next few hours or this week.
On a Mac, the first time you turn on the Claude meter, macOS asks once for permission to read Claude Code's Keychain item. Allow it and the meter starts showing numbers.
Where the numbers come from
Prompt Petal reads the sign in that Claude Code and Codex already keep on your computer. It sends that sign in only to Anthropic and OpenAI, the two companies that run your plans, and asks them how much is used. The meter is off until you turn it on.
Status dots for everybody
Free includes status dots for Claude, ChatGPT and Copilot. A green dot means the service is up, and another color tells you something is wrong before you waste a few minutes wondering whether the problem is on your side.
Gemini and Copilot show status only. The usage meter itself is a Pro feature for Claude and ChatGPT.
A few ways people use it
Some people glance at the meter before starting a long coding session, to see whether the next few hours have room. Others check the weekly view on Monday to pace the week. Both habits take a second and replace the surprise of a blocked message in the middle of a task.
When the reset time is close, the meter tells you exactly when the full allowance returns. Waiting forty minutes is an easier decision when you can see the number.
Your sign in stays on your computer
Claude Code and Codex already keep a sign in on your computer so they can talk to your accounts. Prompt Petal uses that same sign in to ask for your usage, and only Anthropic and OpenAI receive the request. You can switch the meter off again at any time in Settings.
Pro also adds as many prompts as you like, groups, per-app petals and sync across your devices. Free keeps the status dots and five prompts you write and edit.
