FORENSIC ACCOUNTING — TOKEN DIVISION
AUDIT MY MONTH
The Burnmeter judges a prompt. This judges a billing period. Export your usage CSV from your provider's console, drop it here, and see where the money actually went — including what a few boring changes would recover. Your file never leaves this tab — the whole audit runs in your browser. How the numbers are estimated →
WHERE TO GET THE CSV
- — OpenAI: platform.openai.com → Usage → Export.
- — Anthropic: console.anthropic.com → Usage → Export.
- — OpenRouter: openrouter.ai → Activity → Export. One row per generation, and we read the cancelled and finish-reason columns too. Their export caps at the last 30 days.
- — Anything else: a CSV with model / token / cost columns will do. Headers are auto-detected, whether the file is aggregated by day or one row per call.
HOW THE AUDIT WORKS
- — Parsed 100% in your browser. No upload, no storage, no login.
- — Savings are estimates at public list prices (2026-08-24 snapshot), labeled as such.
- — Signals are heuristics: re-sent context, missing caching, flagship overuse, output-heavy patterns.
- — The grade is editorial. The arithmetic is not.
