Turn PDFs into listenable multilingual audio summaries
Upload a PDF and get a condensed set of key points instead of a full-length read-through, so you capture the argument in minutes rather than hours.
Summaries are voiced in many languages with professional-sounding narration, making content usable for audiences that do not share a single language.
The end result is an audio digest you can listen to on the move, suitable for newsletters, class notes, briefings, and internal updates.
An API endpoint lets you convert PDFs to audio programmatically, so the same capability can sit inside your own app or content pipeline.

Share and access study materials worldwide — with AI study tools built in
Search a vast, student-contributed library of lecture notes, summaries, study guides and past exams organised by course and institution.
Generate notes, summaries and revision material from documents so you can study the essentials instead of re-reading everything.
Turn study material into interactive quizzes and flashcards so you can test yourself and target weak spots.
Use built-in text-to-speech to listen to study documents on the go, useful for revision during commutes or downtime.
