Kurzgesagt – In a Nutshell’s apps

Handwriting → Study Material / Notes

Photograph handwritten notes and convert them into structured, searchable study material.

Photograph a page of handwriting and get back something usable: typed, structured, searchable, and turned into questions to test yourself against. It handles the diagrams and the margin scrawl rather than only the neat lines.

What a v1 does5 features
  • Handwriting to text, including diagrams kept as images in place
  • Structure recovered - headings, lists, and what was emphasised
  • Everything searchable across every page ever added
  • Flashcards and questions generated from the notes
  • Export to the note apps people already use

Why this audience

These viewers include a heavy student and researcher population who work in notebooks and then cannot find anything. The content rewards depth over speed. Turning pages of handwriting into searchable, testable material serves the way they actually learn.

Before it can launch

No licence, certification or data agreement stands between this and a launch — app-store review and an ordinary privacy policy aside.

Fifty thousand paying users is the ceiling every one of these pages is drawn against, not a forecast. It opens at a thousand, the bottom of the range, so the first figures you see are the modest ones. What the cap buys is comparability: the same range on every app, and the percentage of the audience it takes as the number that moves.

Is this the one for your audience?

We fund it, build it, and run it. You bring the audience and take a share of the revenue. Nothing to pay and nothing to build.
