Track your remaining usage ata glance.
UseReserve is a lightweight macOS menu bar app that keeps your remaining Codex, Claude, Cursor, Grok Bot, and Antigravity usage visible without interrupting your work.
83% remain
Added Antigravity with Gemini and Claude/GPT allowances. Fixed Cursor showing 100% when no allowance is available, made Claude follow account and workspace changes, and improved tracking stability for Codex and Claude.
Open Codex, Claude Desktop, Cursor, Grok Bot, or Antigravity once, then launch UseReserve to see the limits available on your Mac. macOS may ask permission before UseReserve can read a protected local sign-in.
The UseReserve app is read-only and never stores credentials, cookies, or message content. It reads only the local sign-in information each installed provider needs for an ephemeral usage request.

- Menu bar
- Open UseReserve again if its icon is missing. If your menu bar is crowded, close an unused menu-bar app so macOS has room to show it.
- Sign-in
- Open Codex, Claude Desktop, Cursor, Grok Bot, or Antigravity and confirm you are signed in, then return to UseReserve.
- Claude permission
- Choose Connect Claude in UseReserve and approve access to Claude Safe Storage when macOS asks.
- Cursor usage
- Cursor must be installed and signed in. UseReserve shows Cursor and Other Models when those limits are available for your individual plan. If Cursor has no allowance to report, you’ll see No usage limits available instead of a percentage.
- Grok Bot usage
- Grok Bot must be installed. UseReserve prefers the account signed into Grok Bot, then falls back to Cursor's sign-in if that account is unavailable or rejected. When Cursor fallback is active, choose Use Grok Bot Sign-In to switch accounts; if macOS blocks Grok Bot Safe Storage, choose Allow Grok Bot Access.
- Antigravity usage
- Keep Antigravity open and signed in. UseReserve shows Gemini Models and Claude and GPT models, with the lower remaining allowance in the menu bar. If Antigravity closes, the last reading stays visible until you reopen it and refresh.
- Stale readings
- UseReserve keeps the last available reading during a temporary outage and shows when it was last updated.
- Refresh
- Open the more menu and choose Refresh after reconnecting to the internet or signing in again.
- Hiding an app
- Open the more menu and untick an app under Show/Hide to drop it from the panel. It stops being polled until you tick it again.
- Login Items
- If UseReserve does not start automatically, open System Settings → General → Login Items and enable UseReserve.
