Why the count is an estimate

Provider tokenizers split text differently, and newer model families may change tokenization. Use the provider's API usage field or official tokenizer for exact billing reconciliation.

PDF and DOCX

Reliable document cost depends on extraction, OCR, images and layout. This tool does not claim to support those formats until a proper local parser is implemented.
