Summarize More Than Just PDFs
OneStudy reads the documents students actually deal with — and keeps the parts that matter for the exam.
Textbook Chapters
Turn a 40-page chapter into a summary that captures every key definition, theorem, and example — organized the way you'll be tested on it.
Research Papers
Get the problem, method, findings, and why-it-matters of any paper in plain language, then dive deeper with the tutor for a literature review.
Lecture Slides
Compress a slide deck into tight notes and fill in the context that lived in the professor's voice, not on the slide.
Articles & Handouts
Paste a URL or upload a handout and pull out the core arguments, evidence, and terms worth remembering.
From material to mastery in three steps
Upload your PDF
Drag in a document, paste text, or drop a link. Big files and dense chapters are welcome.
Get a smart summary
OneStudy identifies the key concepts and structures them for recall — not a generic TL;DR, but a study-ready breakdown.
Study the whole document
Generate flashcards, quizzes, a practice test, or a podcast from the summary, and ask the tutor anything about the source.
A Summary That Does Something
Most summarizers hand you a paragraph and call it done. OneStudy hands you a study system.
Structured, Not Shallow
Summaries are organized by concept with headings, key terms, and examples — built so you can revise from them, not just skim them.
Instant Flashcards & Quizzes
Every summary becomes active-recall flashcards and practice questions in one click, turning reading into real retention.
Chat With Your Document
Ask the AI tutor to explain a paragraph, define a term, or work an example — it answers from the document you uploaded.
Lightning-Fast
Summaries land in seconds, even for long documents, so you can move from upload to studying without the wait.
Turn PDFs Into Podcasts
Convert any document into a natural-sounding audio summary and review it hands-free between classes.
Built From Your Material
Summaries and tutor answers come from the document you uploaded, not the open web — so you're studying your syllabus, not something generic.
OneStudy vs. a Generic Summarizer
A paragraph of summary doesn't help you pass. A summary that becomes flashcards, quizzes, and a tutor does.
