MarkItDown

Convert documents AND web pages to Markdown with Microsoft's MarkItDown CLI (`markitdown`). Covers PDF, Word, PowerPoint, Excel, images (EXIF/LLM description), audio/video transcription, HTML, YouTube and direct URLs. Use when the user asks to read / analyze / summarize / extract / translate / Q&A about a rich-format file or a public web page, or to deposit such content into a knowledge base; converting to plain Markdown first also cuts token cost. Also ships optional local-only token-cost estimators (`scripts/token_saver.py` for a converted file, `scripts/measure_tokens.py` for arbitrary text
