01 / Interactive video lessons
Made for you.
Ready to respond.
A personalized video lesson built around the learning objectives you need to master. Instead of watching a fixed recording, you work with a lesson that responds when you ask: switch narrators, hear a concept explained in different words, work through new questions and ask your own.
Request a quote“Split the launch velocity into two parts. Only the vertical part is changed by gravity.”
“Picture two motions at once: steady sideways, and up then down under gravity.”
“Here is a new problem on the same objective. Try it before the hint.”
“No horizontal force acts once it is launched, so the horizontal speed stays the same.”

How it works
Your curriculum.
Your objectives.
Every lesson starts from your curriculum. Share your subject, academic level and the topic you are working on, together with where your understanding currently breaks down. We map that topic to the specific learning objectives it involves, so the lesson focuses on what you still need, not on what you have already mastered.
Lessons are priced by learning objective, because topics vary widely in size. The starting price of $150 includes your first two objectives, and each additional objective is $60. Before you pay, you receive a quote that lists every objective the lesson will cover.
Interactive video lessons are available for Physics, Chemistry and Mathematics within IB, AP and A Level, and are delivered in English.

Share your topic
Tell us your curriculum, academic level and the topic or question you want to work on. Explain what is already clear and where the difficulty begins.
- 02
Approve your objectives
We break the topic into the learning objectives it involves and send a quote listing each one. Work begins only after you approve the scope and pay the invoice.

Learn your way
Use the lesson as often as you need for 12 months. Return to it before tests, revisit difficult steps and practice until the reasoning is clear.
Inside your lesson
One lesson.
Many ways in.
A recorded video explains a topic once, in one way. An interactive video lesson changes with you. When an explanation does not land, you can ask for it again in different words, without waiting for a scheduled session.
When you feel ready, the lesson can work through new questions with you, so you see the same reasoning applied to problems you have not met before. And when something is still unclear, you can type your own question and receive an explanation within the lesson.

Type a question about the topic and receive an explanation connected to the content of your lesson.
Quality and transparency

Open about AI.
Erenext produces interactive video lessons with the support of AI tools. Educators remain responsible for what you learn: they prepare and approve the core content of every lesson, and the explanations and questions generated while you study are designed to stay within that approved content.
Content generated during lessons is also reviewed by our educators afterward, so any errors can be identified and corrected. If you notice something that looks wrong, write to info@erenext.com.

AI narrators
The narrators in our lessons are avatars and voices generated by AI. They are not real people, are not based on the likeness of any Erenext educator and do not speak for any educator.

What our AI tools receive
The AI tools we use receive lesson content, learning objectives and official curriculum guidance. We do not send your name or contact details to them. Please do not include personal information in the questions you type.
