Vocabulary AI

Vocabulary AI is a comprehensive language-learning platform available as a website, mobile app, and browser extension, built for people who learn languages through real-world reading rather than textbook drills. Unlike standard translation tools that you use once and forget, Vocabulary AI lets you save new words you encounter while reading foreign language content online, then systematically practice them using the Ebbinghaus forgetting curve — a scientifically validated memory retention technique that times your reviews perfectly to prevent forgetting. Whether you're working toward fluency in a new language or maintaining one you've already learned, Vocabulary AI turns every article you read into an opportunity to grow your vocabulary and actually make it stick.
