Watch how it worksPrecision teaching measures progress on a logarithmic scale — because skill rates grow multiplicatively. Each session doubles the previous. Standard study methods stay linear. After ten sessions, the gap is unrecognizable.
Lindsley, O. R. (1990). Precision teaching: By teachers for children. Teaching Exceptional Children, 22(3).Below this rate, you're still thinking. At this rate, you're knowing. Munin's 20-second rounds hold you to it.
Haughton, E. (1972). Aims — growing and sharing. Behavioral Research and Therapy.Skills trained to fluency are retained at ~85% after three months without practice. The same content drilled to accuracy-only — the flashcard pattern — drops to ~25%. Same knowledge in. Different durability.
Binder, C. & Watkins, C. L. (1990). Precision teaching and direct instruction: Measurably superior instructional technology in schools. Performance Improvement Quarterly, 3(4).Saying a word aloud activates the motor and auditory cortex in addition to the visual — three encoding pathways instead of one. Across 28 experiments, spoken items beat silently-read items on recall by an average of 10–15 percentage points.
MacLeod, C. M. et al. (2010). The production effect: Delineation of a phenomenon. Journal of Experimental Psychology: Learning, Memory & Cognition, 36(3).Real fluency training falls apart at the speed of speech. Munin is built on a custom pipeline that hears, interprets, and advances — in the time it takes to say a word.
An audio algorithm listens to every moment you speak. The instant you stop, the next card flips. No "next" button. No tap.
Every utterance is graded against every active answer through a seven-layer scoring stack. The right answer wins — even when the microphone hears it wrong.
The whole flow is controlled by your voice. No tapping. No swiping.
People are not slow learners. They are fluent learners who have been taught with infrequent practice.After Ogden R. Lindsley · founder, precision teaching
No. Flashcards let you flip a card and judge yourself — which often creates a false sense of mastery. Munin makes you say the answer out loud and measures whether you actually got it. That's the difference between recognizing and knowing.
Munin is built for it: upload your material, Munin generates the practice, and you train to fluency — 20 correct answers in 20 seconds. Unlike generic flashcard apps, Munin measures active recall out loud instead of letting you grade yourself.
Audio is transcribed in real time and discarded immediately. We never store recordings — only the round summary (score, time).
Yes. A seven-day trial is included for every new user. No card required.
Anywhere — on your phone, iPad, or PC. Anything with a screen, a microphone, and an internet connection.
