Students: turn whiteboards, handouts and notes into searchable PDFs

Searchable PDFs with on-device OCR: snap the whiteboard before it's erased, keep every handout in one PDF per course, and find any formula or definition in seconds before the exam — all on your phone.

Quick answer

Use Whiteboard mode for the board and Document mode for handouts, save them into one folder per course, and let on-device text recognition make every page searchable. Before the exam, search a term across all your scans, copy the paragraph you need, or export a chapter to Word to make your own summary.

The problem with photos of the board

Most students already take photos of the whiteboard. Then they sit in the camera roll between selfies and memes, crooked, with glare across the most important line — and impossible to find the night before the exam.

Scanning instead of photographing fixes three things at once: the board is straightened and cleaned up, it lands in the right course folder, and every printed word on it becomes searchable.

Step 1 — Capture the board before it's erased

Pick Whiteboard mode on the Scan screen. It straightens the board, cuts the glare and strengthens faint marker strokes. Stand as square to the board as you can; if it is wide, scan it in two halves. It all works offline, so a weak lecture-hall Wi-Fi doesn't matter.

Step 2 — One folder per course

Create a folder for each course and save every board, handout and worksheet there. Once a week, merge that week's scans into one PDF — Biology — Week 6 — so revision is a handful of files, not hundreds.

Step 3 — Search instead of scrolling

Every page is read on your phone a few seconds after you save it. The night before the exam, search for “mitosis” or “Fourier” and jump straight to every board and handout that mentions it.

Step 4 — Copy, quote and summarize

Need a definition in your notes app? Copy text from the page, or select just the sentence you need. For a full chapter, export it to Word and rewrite it in your own words — one of the best ways to actually remember it.

Study habits that make scanning pay off

Common questions

Can it read my handwriting?

Not yet — text recognition works on printed and typed text, and on clear whiteboard writing it often catches headings. Handwritten notes are still saved as clean scans you can read and share.

Is it OK to photograph the whiteboard in class?

Usually yes for your own study, but ask your teacher if you are unsure, and don't share class materials publicly without permission.

Does it work without Wi-Fi in a lecture hall?

Yes. Scanning and text recognition run entirely on your phone.
