Every answer shows the unit it came from and says how sure it is. Two different AI models answer your question separately; if they disagree, you're told rather than guessed at.
One label on every answer, in every part of the app. Learn it once.
Found in your uploaded course material, and both models agreed.
Both models agreed, but the answer came from general knowledge, not your book.
The models read the question differently. Check your material or ask your tutor.
Add the NOUN PDF for a course from the Course materials screen — up to 400 pages. Or pick a course already in the library.
Type a question, paste a TMA, or snap a photo of it. The tool searches your material first and shows the module and unit it used.
Read the answer, open the working, and use the same material for summaries, a mock exam or voice study.
Any NOUN course you have the material for.
Upload the course PDF from NOUNs e-courseware — up to 400 pages per file, and up to nine courses at a time. The tool splits it by module and unit so answers can point back to the exact unit. Courses already uploaded by other students are grouped by semester and ready to use, and you can also keep private notes in your own notes bank.
What it won't do: it won't write your TMA for you, and it won't replace your course book. Scanned photocopies read less well than the original PDFs, and if a unit isn't in your material the answer is labelled Likely, not Verified.
