You explain a concept out loud. The AI plays a confused student and asks exactly where your understanding has holes — then a real ML engine, not the chatbot, scores how well you actually understand it.

The problem

We turn confusion into confidence.

The gap between recognising an idea and being able to reconstruct it is where every exam surprise lives. Lucid is built on the Feynman technique and the protégé effect: the fastest way to find the edge of your understanding is to try to teach it.

Did you know?

Learners who teach a concept out loud retain 90% more than those who simply re-read it silently. That's the protégé effect Lucid is built on.

Master any subject by teaching it

The Protégé Effect proves that explaining a concept out loud is the most effective way to lock it into your long-term memory.

Feynman Technique

Explain complex ideas simply. If you stumble, you've found a gap in your knowledge.

Active Recall

Force your brain to retrieve information instead of passively re-reading notes.

Targeted Feedback

Our AI plays a confused student, asking questions that test your true understanding.
