AI reviewer maker from a picture
No scanner, no retyping. Photograph the handout with your phone, upload the picture, and get a reviewer built from what is on the page.
No credit card. Free plan available forever.
How it works
Take the picture
PNG, JPG/JPEG or WebP. Shoot the page square-on with even light and all four corners in frame.
Upload up to 10 pictures
Several pages can go into one material, so a whole handout becomes one reviewer.
Generate and answer
5 to 50 items with answers and explanations, saved so you can answer them again.
Getting a picture that works
Almost every weak result traces back to the photo. The three usual causes are an angled shot where the far edge blurs, uneven light leaving half the page in shadow, and a crop that cut off the part that mattered.
Shot square-on in daylight with all four corners visible is enough — no app, no scanner, no editing. If a page spans a spread, photograph each side separately.
Handwriting is generally fine. Faint pencil and heavy overlapping annotation are the cases that struggle, and a brighter photo usually fixes both.
One habit is worth building: photograph the handout the day you receive it rather than the week before the exam. The picture takes ten seconds, the reviewer takes another thirty, and answering ten items in the same week you were taught something is worth far more than answering fifty the night before.

Common questions
Do I need a scanner app?
No. An ordinary phone photo taken square-on in good light is enough.
Can it read handwriting?
Usually yes, because the page is read as an image in context rather than character by character. Faint pencil is the main exception.
How many pictures can I upload at once?
Up to 10 files per study material, so a full handout can become one reviewer.
Does a blurry or angled photo still work?
Sometimes, and the result is noticeably weaker. If a reviewer comes back with vague or repetitive items, retake the picture square-on in better light before assuming the material was the problem — the photo is the usual cause.
