Teachling: Learn by Teaching

The surest test of understanding? Explaining it to someone else.

Teachling flips studying on its head. Upload your lecture notes, a textbook chapter, or any study material — then teach it to Pip 🐣, a curious AI student who starts from zero. Pip asks the questions a real beginner would, gets things adorably wrong, and only truly "learns" when your explanations are clear, correct and complete.

★ Watch understanding grow — every explanation is graded; vague or wrong teaching doesn't move the needle
★ Catch sneaky misconceptions — Pip sometimes repeats your lesson back slightly wrong; spotting it sharpens you
★ Expert backup — stuck yourself? Ask Sage 🦉, your private AI tutor, then go back and teach it right
★ Works with PDFs, notes, or pasted text
★ Based on the Feynman technique, used by top students everywhere
