ARLTS is a free, non-profit companion platform for English learners — built to make certain vocabulary and grammar are locked in before a learner's time with a real teacher or tutor gets wasted relearning words they already ought to know cold.
Ten distinct practice activities — recognition, gap-fill, error-correction, dictation, and reading among them — cover close to 7,300 curated items over CEFR levels A2 through C1 (anchored to the Oxford 3000/5000 word lists), each checked for quality and clarity before it's published.
A Test Center turns every result into a targeted retest of exactly what a learner missed, rather than a number left behind. A Library lets learners bookmark and review words caught "in the wild." A Find a Teacher directory connects learners with vetted tutors when they're ready to practice out loud.
No login wall on the core learning path. No ads. No paid tier gatekeeping the content that matters most.
Built and kept free for learners who want a rigorous, affordable way to build real command of English vocabulary and grammar — the foundation everything else in language learning rests on.
