AI reviewer maker from PDF
Most modules and handouts arrive as PDFs. Upload one and get a reviewer built from it — items with answers and explanations, ready to answer straight away.
No credit card. Free plan available forever.
How it works
Upload the PDF module
Up to 100 MB. Scanned modules work as well as digital ones, because the pages are read as images when there is no text layer.
Generate items from it
5 to 50 items per reviewer, at the level you choose.
Answer, then review the explanations
Score and elapsed time are recorded, and the reviewer is saved so you can answer it again later.
One module per reviewer
The single biggest factor in reviewer quality is how narrow the source is. A reviewer generated from one module covers it densely; one generated from a whole semester of modules covers none of them properly.
So upload module by module. Ten items per module, answered the same week, is more useful than fifty items spread across everything you have studied.
Scanned modules are fine. If a set comes back thin, the usual cause is a page that is too faint or shot at an angle rather than anything about the content.
Split long PDFs before uploading rather than after. A 300-page compiled reviewer produces items that skim the whole thing; the same PDF cut into ten chapter files produces ten reviewers that each actually test a chapter. Most PDF readers can export a page range in a few seconds, and it is the highest-leverage minute you will spend on this.
Works well with
- PDF modules and handouts from your school or review centre
- Scanned modules with no text layer
- Exported slide decks saved as PDF
- Long PDFs split into one reviewer per chapter
- Any language — items come out in the language of the module

Common questions
Does it work with a scanned PDF?
Yes. The pages are read as images when there is no text layer, so scans and photocopies work.
How big can the PDF be?
Up to 100 MB per file, with up to 4 GB stored per account. Long PDFs still work better split by chapter.
Is it really free?
The free plan gives you 5 materials, 5 reviewers and 10 items per reviewer with no credit card. Premium raises the item cap to 50 and removes the material and reviewer limits.
Can I combine several PDFs into one reviewer?
Yes — up to 10 files can be attached to a single study material and are treated as one source. That works well for a chapter split across handouts, and badly for a whole semester at once.
