Scriveno reads photos or PDFs of handwritten math, physics, and chemistry notes and converts them into publication-ready LaTeX, PDF, DOCX, or Markdown — not just plain text. It captures hand-drawn diagrams and chemical structures alongside the equations, renders a live typeset preview right in the browser, and can read the transcription aloud with text-to-speech. Free to start, with a Pro plan for heavier use (1,000 pages/month, $2.99) and a pay-as-you-go developer API ($0.003/page) for teams building conversion into their own product.
