Diagram to video: a kidney diagram explained on itself · made with ContentRoof

Revision that explains, not just repeats

Reading the same page again is the slowest way to revise. What helps is having it explained: what happens first, what it causes, why each part matters. Upload the page and you get exactly that, a teacher's walkthrough of your own material, with the camera on each part as it's named and the things that flow and move shown moving.

Questions

Can it read my handwriting?

A neat, clear page usually works. Messy or faint handwriting is harder; a printed figure from the textbook is the most reliable.

Is my picture redrawn?

No. The video is made on the exact picture you upload, so every label matches your source. Only the camera, highlights, labels and moving dots are added.

Which languages?

Eleven: English, Arabic, Urdu, Hindi, Spanish, French, Portuguese, German, Italian, Russian and Polish. Narration, captions and labels are in the language you pick, even when the picture is in English.

Is it free?

You can try it free with a Google sign-in. Students and teachers who sign in with a school email (.edu, .ac.uk, .edu.pk and the like) get ContentRoof Pro free.
