Upload Your Textbook in PDF or ePub Format
Drag your textbook file into Otio or connect Google Drive, Dropbox, OneDrive, or Box. The textbook stays in your workspace permanently.
Many institutional textbooks are distributed as ePubs. Otio handles both formats so you can work with whatever your course provides.

Ask Chapter-Specific Questions
Instead of reading chapter 8 linearly, ask what it says about a specific concept. Otio surfaces the relevant passage and cites the exact page.
Before your exam, ask targeted questions about the concepts you need to review. Know exactly where to go in the textbook for deeper study.

Cross-Reference With Lecture Slides and Course Papers
Add your lecture slides and supplementary readings to the same session. Ask a question that spans the textbook and the papers your professor assigned.
Otio shows you how the sources connect. Every answer cites back to the exact page or slide so you can verify and review.

Choose the AI Model That Fits Your Discipline
Technical content benefits from model flexibility. Choose the AI model best equipped to handle medical terminology, legal reasoning, or engineering concepts.
Otio consolidates multiple AI models in one workspace. No more copying prompts between ChatGPT, Claude, and Gemini.

Targeted Questioning, Not Static Summaries
Ask Specific Questions Instead of Reading Generic Summaries
Most tools generate a static summary of each chapter. When the exam asks about a specific concept, the summary doesn't help. Otio lets you ask what chapter 6 says about X. The answer cites the exact page so you know where to review.
Permanent Workspace, Not One-Time Summaries
Upload your textbook once. Ask different questions across twelve weeks of study. Other tools treat each session as disposable. Otio keeps your textbook available all semester so your study system grows with you.
Cross-Source Capability for Multi-Material Courses
Add your textbook, lecture slides, and supplementary papers to one workspace. Ask questions that span all three. Exams test synthesis across materials. Otio makes that synthesis visible and traceable with page-level citations.
Every Answer Cites the Exact Source
Otio works from the file you uploaded, not from general training data. Every answer traces back to the exact page or passage. No hallucinated references. No invented page numbers. Verify everything in one click.
Model Flexibility for Technical Content
Choose the AI model best suited to your discipline. Medical, legal, and engineering textbooks require precision. Otio consolidates ChatGPT, Claude, Gemini, and other models in one workspace. No more copying prompts between tools.

Medical Students Managing Dense Anatomy and Pharmacology Texts
Medical textbooks are hundreds of pages of technical content. Ask Otio what chapter 12 says about a specific drug mechanism and get the exact passage with the page number.
Generate practice questions from your uploaded textbook. Create mnemonics and analogies to help concepts stick.

Law Students Working Through Case Law and Legal Codes
Legal textbooks and case compilations require precise extraction. Ask Otio to pull key facts, themes, and contradictions across multiple documents.
Every answer cites back to the exact source. Verify everything before it goes into your case brief or exam answer.

Engineering Students Reviewing Technical Manuals and Problem Sets
Engineering textbooks are dense with formulas, diagrams, and technical specifications. Ask targeted questions to extract the specific concept you need.
Cross-reference your textbook with lecture slides and problem sets. See how the theory connects to the application.

Business and Finance Students Synthesizing Case Studies and Theory
Business textbooks pair theory with case studies. Ask Otio to pull arguments across both and show how they connect.
Before exams, ask targeted questions about frameworks, models, and case applications. Know exactly where to review.

Graduate Students Managing Thesis Research and Literature Reviews
Upload your textbook alongside research papers and course materials. Ask questions that span all your sources and get cited answers.
