Raena AI

Raena AI is an AI-powered study app for high school, college, and university students that turns uploaded learning materials into interactive study formats.

Key capabilities include:

• Multi-format uploads: Import PDFs, notes, images, pasted text, and YouTube links, then generate study resources from the same source content.
• Practice and review tools: Create AI-generated quizzes (multiple-choice, true/false, open-ended) plus flashcards and smart summaries to support active recall and faster revision.
• Audio and visual study modes: Convert notes into study podcasts, generate mind maps, and use Brainrot mode to produce TikTok-style study videos.
• AI tutor chat: Ask questions against uploaded materials so the tutor can explain concepts and connect topics based on the user’s documents.

Pricing: Freemium with a limited free tier; Premium is $6.99/month (6-day free trial) and Pro is $13.99/month (6-day free trial), with higher limits and additional capabilities.

What makes it notable is the breadth of study formats (quizzes, podcasts, games, brainrot videos, mind maps, and tutor chat) generated from a single upload, plus progress tracking across web, iOS, and Android.
