Your AI margin, from the export you already have

Drop the usage or cost CSV from your OpenAI or Anthropic console, add your plan prices if you want margin, and read the result. The file is parsed in your browser and never leaves your machine: no upload, no account, nothing stored.

Exports live at OpenAI platform → Usage → Export, and Claude Console → Cost → Export. Any CSV with a cost column works.

Prefer a human to do this? Email your export and plan prices to hello@useweckr.com and the founder sends the report back, free.
