31Memorize
31Memorize is a vocabulary and verbal test prep platform built around spaced repetition and picture mnemonics. It targets learners preparing for exams like the GRE, GMAT, and IELTS, with curated word lists, practice questions, and analytics that highlight knowledge gaps.
The review system uses the FSRS-5 spaced repetition algorithm to schedule reviews based on your performance. Picture mnemonics connect words to visual cues, and the dashboard tracks learned, reviewed, and fluent vocabulary over time.
You can start free on the Starter Lite plan, then upgrade for unlimited custom words, more practice questions, and deeper analytics. The product previously lived at 31memorize.com; it now runs at 31memorize.saidhasyim.com.
