Four words. One shared idea.
For educators
Your knowledge. Your teaching style.
Give your teaching a home. Materials, presentations and exercises work together. With AI you create anything from single slides to whole courses, VisuApps, exercise collections and mock exams. An AI tutor supports your learners, with your content and in your style.
- CourseLabOne sentence becomes a teaching unit
- VisuLabAn idea becomes an app
- TaskLabExercises, mock exam, exam
- In the lecture hallPresentation, whiteboard, recording
- ReleaseYou decide what the tutor learns from
Your brief to CourseLab
103slides
You name the subject, year and curriculum. CourseLab plans the units, writes the slides and adds matching VisuApps.
For learners
Go beyond learning. Truly understand.
Ask again. Try it out. Take a step back. With the AI tutor, interactive VisuApps and their own notes, learners find their way through the subject.
- StudioSlides, whiteboard and apps in one place
- AI tutorAnswers from your own course
- Explain modeThe tutor guides you through the app
- Practice studioThe tutor asks back
- Your own notesRight on slides and PDFs
Explore the material yourself, here in the protein folding VisuApp, and ask the AI tutor whenever something remains unclear.
For your next step
Every aha leads to something new.
What makes sense already? What needs another look? Feedback shows what helps next, for learners and educators alike, so both can grow together.
- Learning progressWhat has sunk in, what has not
- Micro-lessonsA few minutes, right on the topic
- Teaching feedbackPointers for the educator
- The cycleEvery exercise shows the next step
Your learning path
Activity · 18 weeks
Exercises, quizzes and work in the studio add up to a progress level per topic, and from that the next sensible step.
For all of us
Learning is better when we share it.
A question nobody dared to ask. A quiz that brings everyone in. A course where knowledge grows together. In a protected space, close to the people.

At the heart: VisuApps
Don’t just look. Discover for yourself.
Every VisuApp runs live right here. Control it yourself, or open it in heyprof and let the AI tutor demonstrate it in explain mode.
Monty Hall problem. Three doors, one car, two goats. Switch or stay? Play the famous paradox and let the statistics decide.
More to get your hands on. From primary school to university.
Explain mode
The tutor takes the stage. And you watch.
Ask your question, and your AI tutor demonstrates the answer in the app: it operates it, points at the right places and explains. Just for you, at your pace, as often as you like.
- Ask“Show me why.” Or simply: demonstrate.
- OperateThe tutor sets sliders, swings the camera, starts the simulation.
- Point and explainSpeech bubbles right where it matters. Follow-up questions any time.
Live in heyprof: the tutor demonstrates these VisuApps
The AI tutor
The AI tutor. Answers from your course.
The tutor does not answer from the internet but from your materials and in your style: from slides, script and lecture recording, from the current task with its model solution, and from the solution path so far. It guides Socratically instead of handing out answers.
- From your materials: scripts, slides and exercises as the basis.
- From the spoken word: recordings are transcribed and summarised, with exactly the examples from the lecture.
- Endlessly patient: explains as often as learners need, for five-year-olds or for nerds.
Hey Prof, can you explain the butterfly effect again?
Sure! Picture two double pendulums that start swinging almost exactly alike. The starting angle differs by only a millionth of a degree, and still they soon move in completely different ways.
Show me!
Gladly! I’m starting explain mode: look at the two pendulums on the left, I’m setting the starting angle now …
Board and tutor
Learners mark a section of the board notes, and the tutor explains exactly that spot: with the terminology, notation and approach from the lecture. So even the thousandth explanation is still the educator’s explanation.
From the educator
Bring in materials, recordings and exercises, set individual hints, release what the tutor learns from. heyprof turns this into a mentor in your own style that accompanies any number of learners at once.
For learners
Ask questions, explore VisuApps, practise and see your own progress. Around the clock, as often as you like. Handwritten solutions via photo or tablet get feedback on the working.
Who it is for
Many learning worlds. One home.
From primary school to corporate training: wherever someone wants to explain something and someone else wants to understand it. Each setting has its own page on heyprof.app (in German).
