A child's printed school materials can be turned into revision exercises. By photographing a textbook page, a lesson sheet, or a handout, the Reviscan tool extracts the text and automatically generates questions aligned with the PER (the French-speaking Switzerland curriculum). One point up front, in the name of honesty: this works on print, not on handwriting.
The parent photographs a printed document with their phone. The app reads the text (character recognition), identifies the subject and the concept, then generates revision questions calibrated to that exact content and to the child's level. The exercises then arrive in Escalio, where the child revises them. The benefit: revision is based on the material actually covered in class, not on a generic worksheet found at random, and it stays within the right PER/HarmoS framework.
It is a deliberate choice, made for reliability. Recognising handwriting produces error rates that are too high to generate accurate exercises, whereas printed text is recognised with an accuracy above 98%.
| Works | Does not work |
|---|---|
| Textbook page, school book | The child's handwritten notebook |
| Printed lesson sheet | Notes taken by hand |
| Handout, printed exercise book | Homework written out in pen |
Rather than promising to "read the notebook" and delivering faulty exercises, the tool sticks to what it does reliably.
A time saving, without leaving the curriculum. No need to hunt online for exercises that do not always match the level or the concept being worked on: the child's own material becomes their revision, at the right HarmoS level (the Swiss inter-cantonal school harmonisation).
As far as we know, no other solution in French-speaking Switzerland generates revision exercises from a scanned document. The honest nuance: it is not unique in absolute terms (a French tool offers a similar mechanism), so the accurate wording is "the only one in French-speaking Switzerland to do it", never "no one in the world".
