Alternatives to Synthesis
The world's most-used language learning app — now with AI conversation practice, personalised lesson paths, and an AI tutor for immersive speaking drills across 40+ languages.

Socratic AI tutor that asks guiding questions rather than handing over answers — because the research on learning strongly suggests that's how retention actually works. Covers maths, science, humanities, and coding with guardrails designed for learners of all ages. Backed by Khan Academy's deep expertise in what makes learning stick.
Generate flashcard sets from any text, get AI explanations of wrong answers that actually explain the concept rather than just restating the answer, and use Q-Chat to be quizzed conversationally until the material sticks.
