What is Vocabify? Free AI Flashcards & Spaced Repetition

Building a strong vocabulary is central to learning English, but remembering words weeks or months after first seeing them is where most people struggle.

Relying on word lists, textbook highlighting, or handwritten flashcards is slow and leads to quick forgetting. Vocabify removes this busywork by combining instant AI card generation with modern spaced repetition algorithms.

The Forgetting Curve & The Memory Challenge

Human memory naturally sheds new information within days, as illustrated by the Ebbinghaus Forgetting Curve. Within 48 hours of seeing a new word, learners typically forget over 70% of what they studied unless that material is reviewed at calculated intervals.

Vocabify solves this by continuously measuring your recall strength and scheduling each card for review at the precise threshold right before forgetting sets in. Explore how this memory science operates on our how it works guide.

Why FSRS Beats Legacy Spaced Repetition Algorithms

For decades, digital flashcard systems used Anki's original SM-2 algorithm. While SM-2 was revolutionary in its time, it suffers from significant inefficiencies:

• Over-reviewing known cards: Wasting valuable study time on words you already know well.
• Rigid scheduling intervals: Inability to adapt accurately to individual learning speeds.
• Ease Hell: Once an item is rated poorly, it often gets trapped in a cycle of repetitive reviews.

FSRS replaces static formulas with dynamic machine learning parameters. It computes individualized decay rates for every single card, reducing required daily review volume by 20% to 30% while achieving equal or superior long-term memory retention.
