Feynman technique timer. One idea, in your own words.

Pick one idea. Explain it to an imaginary listener who has never taken the class. The sentence you cannot finish tells you where to look next.

Open feynman technique timer

A plain explanation still needs to be accurate.

Say it plainly. Notice where the explanation gets stuck.

Stage labels show the default plan. Finish a stage to prepare the next, or Reset to change stages and duration.

ExplainCounting down
05:00

Explain one idea aloud as if your listener is new to it.

Ready when you are. Nothing starts automatically.

Choose 1–180 whole minutes before starting.

No saved sessions. No effect on your workspace timer. Leaving or reloading clears this clock. Completion is silent.

Choose an idea you can explain in one sitting

“Electricity” is a whole subject. “Why this bulb goes out when the circuit opens” is a question you can work with. Use the first five minutes to explain the smaller idea aloud or on paper. Start with what happens, then explain why.

You do not need a real audience, a recording, or a polished speech. The point is to notice where you start replacing an explanation with a label. Saying “because of the mechanism” is often the place to stop and ask what the mechanism actually does.

Look up the missing link

During the second stage, go back to a trusted source with a specific question. Find the missing relationship, definition, or step. Resist the temptation to copy an entire paragraph just because it sounds better than your version.

Then close the source and explain the idea again. Add a concrete example. If you use an analogy, say where it stops being accurate: a water-pipe comparison may help with one part of a circuit and confuse another. Simple language should reveal the idea, not erase its conditions.

Use it before writing the final answer

A spoken explanation can expose a gap before you spend an hour turning it into an essay. It also makes a useful preparation round for tutorials, presentations, and interviews. Afterwards, restore any formal terms your course expects and check that you can use them precisely. The timer offers a 5/4/3 practice plan; those lengths are editable, not part of a required method.

Before you start

Does this record my voice?

No. There is no microphone access, recording, transcription, or AI assessment. Explain the concept aloud to yourself, to someone nearby, or in your own notebook.

Do I have to avoid every technical word?

No. Define a term when it is useful, then show what it means in the explanation. The aim is understanding, not replacing accurate vocabulary with vague language.

Can I use the timer for maths?

Yes. Explain why each step in a worked problem is valid, then try a similar problem independently. A fluent description alone is not a substitute for being able to do the calculation.
