  1. Tokens and cost per day, project, session and model.
  2. The ten costliest turns – and, if you opt in, what you asked for and what it led to.
  3. Cost facts without AI interpretation: every number with its computation and assumptions.
  4. What fixed context – AGENTS.md, skills, system prompt – costs per agent.
  5. Nothing to configure in the agents. Everything stays on your machine.
Report overview with tokens over time and summary cards.
Synthetic demo data.
Get started 
pipx install tokenatlas
tokenatlas open

The agents delete their own logs. For a history that stays, schedule tokenatlas collect – see the README.
