Mathpix
Follows how Mathpix turns formulas and PDFs into editable text, covering screenshot recognition, whole-document conversion, and the developer API, plus the cases where recognition still slips.
Mathpix converts formulas, tables, chemical structures, and handwriting from images and PDFs into editable text, returning LaTeX, Markdown, MathML, and other formats. Coverage spans the everyday shortcut of grabbing an equation off the screen, how well whole PDFs survive conversion to Word or LaTeX, and the trade-offs developers weigh when putting its recognition API behind a live feature: latency, batch throughput, and cost per page.
