Vocabulary.com

Vocabulary.com combines a learner-friendly dictionary with adaptive vocabulary-building games and activities. Definitions are written in plain, friendly language rather than dense dictionary-speak, and the site's adaptive learning system adjusts word difficulty and repetition based on how well a user already knows each word.

Anki

Anki is a flashcard application built around spaced repetition, using an algorithm to schedule reviews so learners spend more time on challenging material and less on cards they already know well. It is free and open source on desktop (Windows, macOS, Linux), with source code publicly available on GitHub and an extensible add-on ecosystem built by the community.

Lingvist

Lingvist is a language-learning app focused on vocabulary acquisition, using an AI-driven spaced repetition algorithm to identify which words a learner is about to forget and resurface them at the right time. Rather than fixed lesson units, it places new learners at an appropriate difficulty level automatically and prioritizes practical, high-frequency vocabulary drawn from real sentences. The app covers over 60 languages under one subscription and includes a Custom Decks feature for building vocabulary lists around a specific interest, job, or industry. Lingvist also offers a classroom product for teachers, and the core app is ad-free across its mobile and web versions.

It covers over 200 languages, from major world languages to niche and constructed ones, and includes exam-prep tracks for tests like IELTS and CEFR levels.
