modules / v0.2
Three primitives. One feedback loop.
Feyn doesn't want to be a chatbot. Each module is single-purpose and composes into the technique.
Feedback
Submit a note. Get a precise breakdown of mistakes, blind spots, and three resources to close the gap.
Simplify
Compress jargon-heavy notes into something a beginner can follow without losing the technical substance.
Explain
Type a topic — get a 10-year-old-grade explanation with key terms surfaced in monospace.
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.
- 01
Pick a concept
Choose something you almost understand. The discomfort is the signal.
- 02
Explain it plainly
Write as if to a curious 10-year-old. Use FeynApp to refine the wording.
- 03
Surface the gaps
Run feedback. The mistakes you can't talk around are exactly what to study.
- 04
Simplify the loop
Re-explain. Compress. Repeat until the language feels effortless.
