Sometimes you already have the answer, and it still does not make sense. Rumina is a visual AI tutor for the moment you are stuck on a concept, a problem, or a question you cannot quite untangle. Instead of returning another wall of text, Rumina turns your question into a visual lesson built around what you need to understand. ASK A REAL QUESTION Type it, say it, or add an image. Start with the question exactly as you have it, even if you are not sure how to phrase it. SEE THE IDEA, NOT JUST THE ANSWER Rumina explains ideas through diagrams, charts, comparisons, timelines, animated scenes, and interactive visuals. Abstract concepts become something you can inspect and follow. LEARN ACTIVELY Pause, make predictions, answer quick questions, and check your understanding as the lesson unfolds. Rumina helps you think through the idea instead of simply giving you something to copy. LEARN FROM WHAT YOU MISSED When an answer is wrong, Rumina explains what changed and why. Feedback stays connected to your reasoning, so a mistake can become the next step in the lesson. ASK UNTIL IT CLICKS Ask a follow up without starting over. Rumina keeps the lesson context in view and helps you explore the part that is still unclear. Bring the question you are stuck on. Rumina will help you see it more clearly. Rumina is available on iPhone. AI generated lessons may be incomplete or inaccurate. Verify important information with trusted sources.
