Tally

Your AI tokens, right next to the clock.

Tally lives in the Windows taskbar and counts the tokens you burn with your AI coding agents, by day, week and month. Everything is read locally: no API, no key, no account.

What it does

• A system tray icon, with a Today: 1.2M tokens tooltip on hover.
• One click opens the window: today, 7 days, current month, a 30-day chart, and a breakdown by agent and by model.
• Input, output, cache read and cache write, with a setting to count cache or not.
• Live updates while an agent writes.
• Optional launch at Windows startup.
• Updates itself when a new version is out.

Your agent isn't there? Add it, it's one Rust file.

Install

Download the .msi or .exe from the latest release and run it. Windows 10 or 11.

From 0.2.0 on, Tally checks GitHub for new versions and offers to install them in one click. If you are on 0.1.x, install 0.2.0 over it once; your data is kept.

FAQ

Does my data leave my PC? No. Tally reads the logs your agents already write to your disk and only keeps counters in %APPDATA%\Tally\tally.db. The only network request is the update check against GitHub Releases. No telemetry.

Does Tally change my agents' files? No, it only reads them.

macOS and Linux? Not yet. Tally is built with Tauri, so it is possible later.

Develop

You need Node 22+, stable Rust and the Tauri prerequisites for Windows.

npm install

Tests:

npm test
cd src-tauri && cargo test

Release build (.msi and .exe in src-tauri/target/release/bundle/):

npm run tauri build

Outside Tauri (npm run dev), the front end shows demo data.
