Leeway

Claude, ChatGPT and Gemini usage — how much of the 5-hour and weekly limits you have used, or what is left — in Chrome's toolbar badge, a popup and an always-on-top overlay. Free and open source.

Add to Chrome (Chrome Web Store) · Website · 한국어 · Privacy policy

• Shows the percentage and reset time that your signed-in usage pages show — not a token-count estimate. Used by default; one click switches every number to what is left.
• No sign-in, and no cookie, password or API key to paste. No server, no analytics; session tokens are never stored.
• Toolbar badge for the service closest to its limit (color-coded), and a floating always-on-top overlay (Chrome 116+).
• Plan names (Max 5x, Plus, …), every Claude organization of your sign-in, UI in 6 languages.

Unofficial project. Not affiliated with Anthropic, OpenAI or Google.

The extension uses the normal Chrome profile that is already signed in. It does not use Playwright, automate sign-in, or copy cookies/passwords out of the browser.

Service	How usage is read	State
Claude	claude.ai authenticated internal usage endpoint	working
ChatGPT	chatgpt.com internal usage endpoint (the one its Settings > Usage page reads)	working — confirmed in a logged-in Chrome on 2026-10-15 (an account with a 30-day limit); accounts with 5-hour/weekly limits not yet seen
Gemini	gemini.google.com/usage page, read from an already-open tab	working — reading confirmed in a logged-in Chrome on 2026-10-16; needs that page open

None of these are public, stable APIs. They may change without notice.

Install from source (load unpacked)

The extension keeps the latest usage in its own storage and shows it in its popup and toolbar badge.

1. Open chrome://extensions, enable Developer mode, and choose Load unpacked.
2. Select this project's extension folder. If an older copy is loaded, remove or reload it.
3. In the extension popup, turn on Claude, ChatGPT and/or Gemini and allow the site permission it asks for. Gemini is read from an open gemini.google.com/usage tab — keep that page open (the Gemini usage button opens it) for its values to refresh.
4. Keep the normal Chrome profile signed in to those services. Values refresh every minute, and again when you open the popup or the Leeway window (unless they were read in the last 30 seconds); Refresh in the popup reads them again right away.

The floating overlay is built into the extension (click Open overlay in the popup, then Float on top, or just press Enter); it uses Chrome's Document Picture-in-Picture, so there is no separate app to install.

Popup

For each service that is turned on, the popup shows how much of each limit is used and when it resets. The Used | Left switch at the top of the popup turns every number — popup, overlay and toolbar badge — into what is left, and back; the choice is kept. The 5-hour limit is the large number; an account without a 5-hour limit (e.g. ChatGPT Pro) shows its weekly limit there instead. 0% is shown as 0%; a value that could not be read is ?.

• Colors follow what is left, whichever way the numbers read: green with half or more left, orange from 20% left, red below that — so 85% used is red. The bars are as long as the numbers shown.

• The plan (e.g. Max 5x, Plus) is shown next to the service name when the service reports it. Gemini does not, so it has none.

• One claude.ai sign-in can belong to several organizations (a personal plan and a Team workspace, say). Each one with chat limits gets its own block, named by its plan, so you can see which has how much left. The first one is the main value (the toolbar badge and the overlay's collapsed line).

• When a read fails, the last good values stay visible, dimmed, with how old they are. Hover the status label for the failure reason.

• Values older than 6 minutes (three missed refreshes) are dimmed; a good read that old is marked Outdated.

• Reset times come from the services as exact times. Only ChatGPT's page fallback gives relative "4시간 20분 후 초기화"-style text; the popup counts that down (in the current UI language) from when it was read.

• Turning a service on asks Chrome for that site's permission. If the popup closes while Chrome asks, allowing it still turns the service on.

• The UI is available in English, Korean, Spanish, Chinese (Simplified and Traditional) and Japanese. Chrome picks it from your browser language, falling back to English.

Other Chrome profiles (optional)

To see several Claude (or ChatGPT, Gemini) accounts at once, sign in to each in its own Chrome profile and install Leeway in each. With the Leeway helper installed, every profile's popup and overlay also show the other profiles' usage.

1. Download leeway-helper.exe from the latest release (the popup's Get the helper (Windows) link goes straight to it) and run it once. It registers itself for your Windows user (no administrator rights) and copies itself to %LOCALAPPDATA%\Leeway\helper. Each release also has leeway-helper.exe.sha256 to check the download against.
2. In each profile's popup, open Experimental and turn on Other Chrome profiles (Chrome asks for the "communicate with cooperating native applications" permission), then give the profile a name, e.g. Work.
3. Each profile then sends its own values on every refresh and shows the others' under its own. The toolbar badge still shows only this profile.

This is an experimental, Windows-only feature. The helper is not code-signed yet, so Windows SmartScreen may warn the first time it runs, and Windows 11 Smart App Control or a work PC's policy can block it.
