Spaced repetition built exclusively from your spoken mistakes
Standard spaced repetition apps feed you thousands of generic vocabulary cards you will never use. nthoughts applies the Leitner box algorithm strictly to errors you actually uttered in conversation. If you never made the mistake, you will never waste time reviewing it.
Why Passive Wordlists Fail Spoken Fluency
Flashcards work well for memorising facts (medical terms, capitals, historical dates). But spoken grammar is procedural knowledge — a motor habit executed under millisecond time constraints. Reviewing a generic wordlist on your phone does not activate the neural pathways required to utter the phrase correctly while presenting in a Zoom meeting.
By turning your live conversation errors into active verbal recall prompts, nthoughts bridges the gap between theoretical grammar awareness and automatic spoken delivery.
How Your Spoken Error Moves Through Leitner Boxes
Immediate Error Capture
Spoken error isolated by Maya during dialogue. Entered into queue for 24-hour verbal recall.
Short-Term Consolidation
Retested after a 48-hour gap. Answered correctly? Promotes to Box 3. Slipped again? Resets to Box 1.
Mid-Term Retention
Retested after four days of conversational distraction to verify true structural retention.
Habit Automatisation
Tested after an eight-day span. Prompts require rapid vocalisation under simulated time pressure.
Permanent Mastery
Item has entered permanent oral motor memory. Sampled monthly to verify zero regression in live speech.
