Learn anything by explaining it.

FeynApp is a quiet, technical workspace for teaching ideas back to yourself. Write a draft, get feedback, simplify the noise, and ship understanding.

feyn explain 'fourier transform'
$ streaming response · gpt-4o-mini · 3.4s
A fourier transform takes a wave that's tangled up in time and
untangles it into pure tones. Like splitting white light through
a prism — but for sound, signals, anything periodic.
 
Key terms: amplitude · frequency · phase · sinusoid

method / four steps

The Feynman technique, faithfully.

Named after Richard Feynman, who insisted the test of understanding was your ability to teach the thing. FeynApp is the loop, made quiet and frictionless.

  1. 01

    Pick a concept

    Choose something you almost understand. The discomfort is the signal.

  2. 02

    Explain it plainly

    Write as if to a curious 10-year-old. Use FeynApp to refine the wording.

  3. 03

    Surface the gaps

    Run feedback. The mistakes you can't talk around are exactly what to study.

  4. 04

    Simplify the loop

    Re-explain. Compress. Repeat until the language feels effortless.

ready when you are

Stop reading. Start explaining.
