Duolingo

Duolingo uses AI to adapt language learning to each user's level and goals. The AI adjusts difficulty, spacing, and content based on performance, ensuring learners are consistently challenged without being overwhelmed.

I reference Duolingo's adaptive learning approach in education AI projects. Their AI-driven personalisation - adjusting content difficulty, review timing, and exercise types based on individual performance - is a model for how educational AI should adapt.

For Barnsley education and training providers, Duolingo demonstrates how AI can personalise learning paths at scale. The same principles - adaptive difficulty, spaced repetition, and performance-based content selection - apply to any training content.
