Technical Specifications and Limitations

Each page within a document has a strict HARD limit of 14,000 tokens and a SOFT limit of 10,000 tokens over every ten pages. This means that while documents can exceed 14,000 tokens per page, the system will flag content beyond the 10,000-token threshold per ten-page segment as soft-limited.

The system supports file uploads up to 36MB per document, with an additional monthly quota of 500 OCR pages that can be processed through the Recognize OCR page package. The primary token-based pricing structure charges $6 per 3,000,000 tokens, though specific file formats like scanned documents and websites incur higher costs - .doc/docx, ePub, and txt files are priced at 300k tokens per file, while website content processing requires an additional OCR package.

Pro subscribers enjoy expanded capabilities including multiple document handling, unrestricted PDF page numbers, and enhanced formula recognition through GPT-4 support. The platform's browser extension functionality allows users to save time by directly analyzing content without manual file uploads, while the built-in OpenRouter integration lets users choose between multiple AI models for their document processing needs.
