Coursework
Uploading work, photos and PDFs
Several parts of the app take a file rather than typed text: the AI Grader takes your draft and your rubric, Lectures takes a recording, and the course and quiz builders will take a worksheet as their source. They share one set of rules about what can be uploaded, so it is worth reading them once.
Use the attach control wherever you see it
Anywhere the app can work from a file there is an attach control, with a line underneath saying what the upload will be used for. Pick a file and it is read in your browser before anything is sent, so an oversized file is refused straight away rather than after a long wait.
Know which formats are accepted
PDFs, Word documents (.docx), photographs and screenshots (PNG, JPEG, WebP and GIF), and plain text files (.txt, .md and .csv). Rich text (.rtf) is not accepted — it was never actually read, only passed through, so it is refused now rather than pretending. Save it as .docx or a PDF instead. Google Docs are not read directly: export to PDF, or paste the text in, which every one of these screens also accepts.
Keep each file under 32MB
That is the cap for a single file, and it is sized from real scanned documents rather than picked: a 25-page paper scanned at 300dpi — the default on most copiers — runs 21 to 30MB, and a 25-page PDF exported from Word is under 100KB. The app prints the limit under the control and refuses anything larger, with the size in the message. If you are over it, scanning in greyscale rather than colour, or using your phone's own document-scan mode instead of the plain camera, roughly halves the file without hurting how readable it is.
Photograph handwritten work flat and in daylight
Photographs of handwriting are read well, and read far better when the page is flat, fills the frame and is lit from the front. The two usual causes of a misread are a shadow cast across the page by your own head, and a photo taken at an angle so the lines curve away.
Check that it read what you think it read
Where a file is used as a source, the reply refers back to what it found in it. If the first answer discusses a question you cannot see on the page, it has misread the scan — retake it rather than arguing with the answer.
Typing or pasting always works
Every screen that takes a file also takes text. If a scan is being read badly and you cannot get a better photograph of it, typing the question in is faster than fighting the camera.
Long documents cost more credits than short ones
A document is charged by its page count, because that is what the model actually reads — a 25-page PDF is 25 pages of reading whether the file is 40KB or 30MB. The page count and the credit cost are both shown before you send it, so nothing is spent on a file you have not agreed to. Uploading only the pages you need is cheaper than uploading the whole textbook, and gets a better answer.
Common questions
Why was my file rejected as too large?
The limit is 32MB for one file. Photographs are the usual culprit — a full-resolution phone photo of every page adds up fast. Using your phone's document-scan mode rather than the plain camera, or scanning in greyscale instead of colour, gets under the cap without hurting how readable it is.
Can it read my handwriting?
Usually, yes, including handwritten maths. Legibility matters less than the photograph does: a flat, evenly lit page of untidy handwriting reads better than neat handwriting shot at an angle in shadow.
Can I upload a Word document?
Yes — .docx files are read directly now. The text is extracted and used as your source. Images, headers, footers, comments and tracked-change history inside the document are not extracted, so if the part you care about is a diagram, export that page as a PDF or a photo instead. Older .doc files (pre-2007) and documents containing macros are refused; re-save as a plain .docx.
How many files can I attach at once?
One per field. The AI Grader has two fields, because your submission and your teacher's rubric are two different documents and it marks the one against the other.
Is my uploaded work used to train an AI model?
No. What happens to your work, and how to delete it, is covered in the account and privacy guide.
