TECHNIQUE 01
Spaced Repetition System
Reviews words right before you forget them. Each successful recall extends the interval — from 1 day to 3, then 7, then 30. Your brain encodes it as long-term memory.
Kang, 2016 — Policy Insights from Behavioral & Brain Sciences
Meta-analysis of 250+ studies: spaced practice is one of the most robust findings in learning science.
TECHNIQUE 02
AI Mnemonic Images
A unique illustration for each word, connecting meaning to a vivid visual scene. Your brain stores images in a separate channel — doubling the neural pathways to recall.
Mayer, 2021 — Cambridge Handbook of Multimedia Learning (3rd ed.)
Multimedia learning with images + text improves transfer by 89% compared to text-only, across 500+ experiments.
Bui & McDaniel, 2015 — Memory & Cognition
Self-generated imagery produces stronger memory traces than provided imagery, persisting after 7-day delays.
Combined: the most effective vocabulary method available
SRS handles when to review.Mnemonic images handle how to encode. Together they address both sides of memory — storage strength and retrieval strength — which is why LingoSnack users retain 95%+ of learned words after 30 days.
Three steps to permanent vocabulary
Two minutes per day. Words that stick for life.
1
Play a picture quiz
Guess the English word behind each image. Quizzes are made by teachers and creators — every one has a #ID you can share or search.
2
Save words with mnemonic images
Look any word up, then let AI paint a vivid scene that makes it unforgettable. Add your own hint in any language.
3
Review at the right time
SRS schedules each word right before you'd forget it. Each review strengthens the trace.
