Raena AI

Raena AI is an exam preparation tool. An AI study app that turns PDFs, slides, photos, recordings and YouTube links into step-by-step lessons with quizzes, flashcards, podcasts, short clips and a notes-grounded tutor chat that cites the source page. Web, iPhone and Android.

Raena AI is a study app built around a single idea: your own course material should become the study aid, not a generic textbook. You upload what you already have (PDFs, slide decks, Word and Excel files, phone photos of handwritten notes, lecture recordings, YouTube links or pasted text, and more than one source per lesson) and the platform converts it into a structured lesson. Instead of one block of text to reread, the lesson is split into short chapters that explain an idea and then ask a quick question to confirm it landed. A warm-up at the start gauges what you already know, recaps appear when a chapter reveals a gap, and an exam date you enter pushes the plan toward the material that matters most. The lesson is only one of the outputs. The same upload can become a summary with editable tables and formulas, a quiz, a flashcard set, an audio podcast, or a short vertical clip series made from your reading with a selectable visual style. A tutor chat answers questions grounded in your files and shows the page or timestamp the answer came from, which makes it easy to verify rather than trust. Raena also keeps context such as upcoming exam dates and offers a spoken conversation mode for talking a topic through out loud, including a deliberately blunt option for students who want pressure rather than encouragement. The audience is secondary and university students across disciplines: biology, nursing, medicine, law, history, accounting and calculus all appear in the site's testimonials. Studying happens on the web at app.raena.ai, on iPhone and on Android, and the product is designed for switching between them mid-session. Against generic chat assistants, the difference is that answers are anchored to your uploads and the study artifacts are generated together rather than assembled by hand. Against flashcard-only apps, it covers the explanation layer as well. The first lesson is free, and Pro is described as unlocking unlimited lessons and tutoring.
