Pulse

Use Pulse to extract text and structured content from PDFs, images, and Office files with optical character recognition (OCR). Supply a file URL or upload, select pages when needed, and choose the supported Markdown, text, or JSON output options.

Optional figure and table extraction returns captions and descriptions. The result also includes processing metadata such as file type, page count, and processing time. Pass the extracted content to later steps for review or summarization.
