Run the audit

The audit reads a CSV or JSONL file of your own usage. Useful columns are the timestamp, the model id, input tokens and output tokens. Cost is optional. Parezen prices both sides from the versioned price book, so a missing cost does not block the estimate.

• OpenAI. Usage export from the platform console, or the usage API, saved as CSV.
• Anthropic. Usage or cost export from the console.
• Google Gemini. Billing or usage export from the cloud project that owns the key.
• Other usage exports. The same four columns. OpenAI Costs, Anthropic Usage and Cost, AWS Cost and Usage Report and Google Cloud billing export would be read-only connectors. None of them run on this site.

Console labels move. If a button has been renamed, export the same four columns under whatever name they use now.

Planned. Read-only billing connectors are the intended start. Uploading the file in sign up stays in the browser and is a secondary option. The report is an estimate. It does not become a verified saving until real traffic and a bill match exist. Neither exists today.
