Why developers switch from PDF.ai

PDF.ai is focused on PDF workflows. Iteration Layer handles extraction across PDFs, Office files, emails, images, and more.

More than PDF input

Use one extraction API for PDFs, Office documents, EPUB, RTF, LaTeX, emails, images, and other content formats.

Typed business fields

Return typed values for common business fields rather than only schema-shaped JSON.

Multi-file extraction

Process related documents together when a case, invoice, or client packet spans multiple files.
