Control Tower — Mission control for your AI usage

Token ledger

Know where every token goes

Control Tower reads the session transcripts your AI apps already write and turns them into a precise, deduplicated ledger — split by app, model, and project. It's the only tracker that tells Claude Code, Claude Desktop, and Cowork apart.

Exact token counts and costs, per model — including tiered prompt-cache pricing
Per-project rollups, so you know which repo is burning the budget
Six-month activity heatmap — click any day for the full breakdown
Incremental engine: history indexed once, then millisecond refreshes

Live burn rate

Watch your 5-hour block burn

Anthropic limits usage in 5-hour windows. Control Tower shows the active block in real time — tokens, cost pace, burn rate per minute, and exactly when it resets — so you never get rate-limited mid-flow again.

Counts tick live while your sessions run — no refresh button
Official limits straight from your account, alongside the local ledger
Threshold notifications at 80 / 90 / 95 / 100%

Your usage data never leaves your Mac

No accounts. No telemetry. No cloud. Control Tower reads local files and your own provider APIs, stores everything in a local SQLite database, and ships with the full source code — audit it yourself.

Built like a native Mac tool, because it is one

◫

Lives in the menu bar

A glanceable icon that tints as you approach limits. One click for the full dashboard — no browser tab, no electron.

⌁

Six providers, one view

Claude, Codex, Cursor, Gemini, Copilot, and Antigravity — session, weekly, and model-specific quotas side by side.

⚡

Swift 6, all the way down

Native SwiftUI + AppKit, strict concurrency, SQLite-backed storage. Light on memory, invisible on your CPU.

⟳

Real-time, not polled

File-system events drive updates the instant a session writes — counts move while you work.

⌗

CLI included

ct tokens prints your full ledger in the terminal — pipe it, script it, put it in your tmux status line.
