Not a dictionary.
A program.
VocabGap moves the 4,000+ words that matter most into your long-term memory, and keeps them there.
Free every day. Enroll once for your own pace, no subscription.
A few of the words waiting for you. How many do you know?
Words that stay.
Word lists get read and forgotten. VocabGap schedules every word into your memory, using the two best-proven methods in a century of research.
Active recall
You see the word first and try to remember the meaning before revealing it. The effort of retrieval is what builds the memory. It's why flashcards beat rereading.
Spaced repetition
Each word returns right before you'd forget it. Hard words come back sooner, solid ones stretch further out. A word counts as learned only after it survives a 3-week gap.
4,000+ chosen words
A curated program at SAT and GRE level, in high-yield order, with etymology, roots, usage notes, audio, and translations in 17 languages.
Say it right the first time.
Knowing a word is half the job. Every entry carries a plain-spoken usage guide: how formal the word is, where it fits, and the near-twins it gets confused with.
💡 Formal and literary; often reflexive ("abase oneself"); implies deliberate humiliation.
Learn on the move.
Your commute is already study time. Press Start, put the phone away, and VocabGap talks you through today's words: the word, a pause to recall it, then the meaning and an example.
In the car
Knew it? Tap skip forward on your steering wheel. Not yet? Skip back and it comes around again soon. Eyes stay on the road.
On a run
Works with AirPods and any Bluetooth headphones, with the phone locked in your pocket. Your progress saves as you go.
Still real recall
Every card you grade by button updates your spaced-repetition schedule, exactly like a session on screen. Cards you skip keep their place.
Your exam date sets the pace.
Tell VocabGap when you sit the GRE. It works backward from that day and adjusts your daily pace, every day, until every word is in memory.
Measure your gap.
Watch it close.
A 2-minute test estimates how many of its 4,000+ words you already know, from everyday up to GRE level. Retest at milestones and see the number climb.
