FAQ
Is this an exact bill predictor?
No. It is an estimate for AI coding workflows. Provider billing, subscriptions, discounts and limits can vary.
Does the calculator call an AI API?
No. All calculations run locally in your browser and no login is required.
Why do coding agents use more tokens than chat?
They repeatedly consume repository context, command output, diffs, plans and review feedback across many turns.
