# Fuse

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

Canonical page: https://pyrosoft.pro/software/fuse

Status: coming-soon
Platforms: macOS, Windows

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.

Price: Price TBA.

## 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.
