Many formats
PDF, Word, PowerPoint, OpenDocument, EPUB, RTF, Excel and CSV.
Documents
Keep your course materials in one library on your device. Annotate PDFs by hand, and have ostudy read each document once so it can feed your study guides, cards and Tutor.
Annotate PDFs
Open any PDF in your library and write on it. Your marks are saved as you go, and the PDF file itself is never changed.
On an Android tablet the stylus draws while fingers scroll and zoom, and a resting palm is ignored. On a phone a finger draws with every tool.
Zoom in and ostudy redraws that part of the page from the PDF itself, so small print and figures stay crisp.
Annotations are part of every whole-library backup and come back when you restore it.
Processing
When you add a document, ostudy reads it on your device and turns it into a structured map of its pages, headings, tables and figures. Your AI provider receives only the passages a task needs, never the whole file as an upload.
PDF, Word, PowerPoint, OpenDocument, EPUB, RTF, Excel and CSV.
Text recognition (OCR) recovers scanned and image-only pages. On Android it's built in.
Bordered tables are read cell by cell, and pages with tables can be sent as images to models that read them.
Upload or paste a batch of images, such as lecture slides you photographed, and they're read as one source.
What ostudy learns from a document is saved and shared by study guides, cards and the Tutor. Switching AI models doesn't mean reading it again.
Processing carries on while you use the rest of the app, and one failed request doesn't sink the whole document.
From document to study
Each document can make a study guide and a deck of cards in several question types, each citing where it came from. Want more? Make more cards takes instructions, such as “a card for each cranial nerve, with the nursing assessment test”.
Group documents into a subject, set the page range to study from each one, and make one guide across all of them.
Not yet available: handwriting recognition, highlights that snap to the PDF's text, exporting a PDF with your marks, and annotating formats other than PDF.
