Turn scans into study notes
Capture clear lecture pages, recognise the text and turn it into material you can revise.
Photograph one page at a time
Lay the page flat, avoid a shadow from your phone and keep diagrams in the frame. Capture each page in the same orientation.
Recognise the writing
Combine the photos with Scan to PDF, then run OCR in the language of the handout. Search the output for an uncommon word from the original. Equations, handwriting and small labels need a closer check.
Make a revision copy
Use PDF to Markdown for headings and paragraphs or extract text for a summary. For flashcards, write one question and one answer per line with a vertical bar between them.
