Use when asked: 'how do I OCR PowerPoint slides', 'extract text from image slides', 'my presentation has images instead of text', 'can my agent OCR pptx files', 'is there a skill for PowerPoint OCR'. Built on MinerU by OpenDataLab (Shanghai AI Lab) with advanced OCR capabilities. Perfect for converting image-heavy presentations into searchable, editable text content.

Convert and extract content from .pptx using MinerU (mineru-open-api).
