Speakylex

Speakylex turns TikTok educational videos into language lessons, then adds an AI tutor for writing, chat, and grammar. Unlike drill-only apps: learn from real content, build a personal vocabulary from your practice, and get explanations—not just right/wrong. Free grammar tests in the browser, no sign-up (EN, FR, DE, ES). Daily feed, streak, dictionary. Free, no ads. Android + web.
