Duolingo
Duolingo popularised streak-based daily habit building (“don't break the chain”), XP leagues, and ultra-short sessions. Best-in-class for languages; not built for conceptual subjects.
Brilliant
Brilliant's strength is interactive explainers — drag-to-explore diagrams, step-by-step reasoning, and problem-driven learning. Covers computer science, maths, physics, and a growing AI track. Deeper than Duolingo, slower-paced than AI Quest.
AI Quest
AI Quest is a quiz game built specifically for AI literacy in the post-ChatGPT era. Short scenarios test: (1) spotting AI hallucinations, (2) evaluating prompts, (3) recognising bias and over-reliance, (4) understanding the EU AI Act's practical rules. Daily streak + leaderboards keep engagement.
What each does well
- Duolingo: languages, habit formation.
- Brilliant: conceptual maths/science/CS, depth.
- AI Quest: AI literacy specifically, including regulation and ethics (not covered by others).
