Fuse

See how much of each AI plan you have left, from your Mac's menu bar.

Real capture · Fuse 26.9.8.18 The floating notch, expanded from the top of the display: what's left on five signed-in accounts, and when each limit resets.

Overview

Know how much fuse you have left.

Fuse shows how much of each AI plan you have left, in one compact view: remaining-capacity meters, reset countdowns, plan names, credits and spending caps for Cursor, Claude, ChatGPT/Codex and Gemini, plus experimental integrations for GitHub Copilot, Perplexity, Grok and Windsurf.

On a Mac it lives in the menu bar, in a floating notch you can dock to any edge of the display, or in its own dashboard window. Bars drain as you use your allowance, a 24-hour history is drawn from real readings, and a service that goes quiet keeps its last good reading, clearly marked. Add the same service twice and work and personal accounts get separate rows and sign-ins.

You sign in on each service's own page; Fuse keeps only the resulting session, in the macOS Keychain, and never sees your password. It is an independent app that reads what each signed-in dashboard already shows. Fuse isn't publicly released yet: the Mac build needs macOS 14 or later on Apple Silicon, and an earlier Windows build runs from the system tray.

Questions

Does Fuse see my passwords?

No. You sign in on each service's own page in an embedded browser, and Fuse keeps only the resulting session: in the Keychain on a Mac, encrypted for your user account on Windows.

Is Fuse official, or affiliated with these services?

No. Fuse is an independent app from PyroSoft. It reads the same data the services' signed-in dashboards load; those endpoints are unofficial and can change.

Does it count my prompts or tokens?

No. Fuse reports what each service's own dashboard reports.

Why does ChatGPT only show Codex?

ChatGPT's core chat message caps have no self-serve usage source, so Fuse tracks the Codex windows the service does expose.

Will it run on an Intel Mac?

Not currently. The Mac build is Apple Silicon only and needs macOS 14 or later.

Is the Windows build signed?

Not yet. The Windows build (26.8.26.1) isn't Authenticode-signed, so SmartScreen may ask before the first launch. It needs no administrator rights.
