Purpose
Raena AI is an AI learning app that automatically turns user-uploaded notes, slides, lectures, and other content into structured step-by-step courses, helping save reading time and improve comprehension efficiency.
Main Capabilities
- One-click upload, multiple ways to learn: Upload notes once, and Raena can generate courses, quizzes, flashcards, podcasts, games, and other learning materials.
- Step-by-step courses: Courses consist of short chapters, each explaining a core concept, followed by quick questions to check mastery.
- Multiple input formats: Supports PDFs, slides, Word and Excel files, photos of notes, lecture recordings, YouTube videos, links, and pasted text. Multiple sources can be added to a single course.
- Content editing: Including tables and formulas, everything can be edited.
- Short-video conversion: Can turn 200 pages of material into TikTok-style short video clips overlaid on gameplay, making it easy to finish scrolling and finish learning.
- AI tutor: Answers questions based on your notes and shows which page the answer comes from; it also remembers exam dates.
- Voice conversation: You can discuss directly by speaking, with an "Unhinged mode" for strict tutoring.
- Multi-platform support: Available on the web, iPhone, and Android, supporting starting on a laptop and continuing on the bus.
- Privacy protection: Uploaded content and courses are private by default unless you choose to share them; industry-standard encryption is used, and data is not sold.
