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.

About

Wait, Professor

Features
Read full description

You read the same paragraph five times and none of it stays. That is not a you problem. Textbooks are written to be accurate, not to be understood. Wait, Professor gives you a second voice for the exact moment a sentence stops making sense. WHAT IT IS Two tutors in one lesson. Thorne teaches the topic straight, at full depth, nothing watered down. Mila is the one you tap when a sentence lands wrong. She says the same idea again in plain words, then again as an analogy if you need it. She never sighs at you, and she never runs out of patience at 2am. WHO IT IS FOR Students buried in dense material, self-taught developers lost in documentation, and anyone whose brain goes left when the lecturer goes right. If you have ever wanted to put your hand up and say wait, go back, this was built for you. WHAT IT FIXES - Nothing sticks. Every lesson stops to ask you a question, so you find out what you missed now instead of in the exam hall. - Walls of text. Lessons arrive in small pieces you tap through, not one long answer you have to survive. - Nothing to show for it. Each lesson ends with a recap built from the places you asked Mila for help, plus a plan for when to review them. - No time to set anything up. No deck to build, no files to upload, no prompt to get right. HOW IT WORKS - Type any topic. The Krebs cycle, recursion, options pricing, whatever is in front of you. - Answer a few short questions so the course fits what you already know. - Get a real course, lesson by lesson, in the order the subject needs. - Tap Mila for the plain version. Tap Thorne to keep moving. - Answer the checkpoint at the end of each lesson. - Keep the recap. Your courses stay on your shelf and reopen for free. PRICING Three days free, then one subscription, monthly or yearly, covering every course you make. No ads, no locked lessons, no per-course fee, no feature held back for a higher tier. We charge after the trial because every lesson is written by a paid AI model, so there is no permanently free tier and nothing gets drip-fed later. Lessons are generated by an AI model and can be wrong. Check anything that matters against your own course material.
