Mistral Parser

Use Mistral's OCR API to extract text and page structure from a PDF uploaded to Sim or supplied by URL. The current parser returns page Markdown, image metadata, the model, and usage information. Specific Pages accepts zero-based indices such as 0,1,2; leave it empty to process all pages. The block offers Markdown, plain-text, and JSON format values, but its current result uses the structured page output documented below. Base64 image data is a hidden tool input and has no block control.

Use the block

Extract text from uploaded PDF documents, or from a URL.
