lrnos vs Duolingo: which one fits how you study?
duolingo-style daily practice and streaks, but on your own course materials and any subject.
duolingo and lrnos both believe in the same simple idea: short daily practice beats cramming. the difference is what you practice. duolingo teaches its own built-in curriculum for languages, plus math, music, and chess. you follow their lessons, on their content, in their order.
lrnos is for a different moment. you already have your own course materials, the pdfs, slides, documents, and youtube links from your actual class. lrnos reads them, maps every concept into an ordered path, and turns them into a daily plan with practice questions drawn straight from your files. so if you want to learn spanish, duolingo is excellent. if you need to pass your own course, lrnos is built for that.

where Duolingo is genuinely great
- world-class gamification. streaks, leagues, XP, and daily goals make showing up every day genuinely habit-forming, and the streak mechanic is hard to beat.
- huge free language content. you can learn spanish, french, japanese, and more for years without paying, all built and maintained by duolingo.
- speaking and conversation practice. duolingo offers speaking exercises, and its top tier adds AI-powered conversation and roleplay so you can practice talking, which is something lrnos does not do.
- expanding beyond languages into math, music, and chess, with bite-sized lessons designed by a team that studies retention closely.
where lrnos is the better fit
- it works from your materials, not a fixed catalog. upload the pdfs, slides, docs, and youtube links from your real course and lrnos studies what you actually need to know.
- any subject, not just languages. biology, law, accounting, your professor's lecture notes. duolingo cannot teach an arbitrary subject from your own files.
- full coverage in order. lrnos maps every concept into an ordered path and shows the percent of the topic covered, so you finish the whole syllabus, not a sampler.
- questions come from your own source, and FSRS spaced repetition schedules reviews so you remember it at exam time, with a short explanation of why each answer is right.
the verdict
pick duolingo if your goal is to learn a language, or to dabble in math, music, or chess, and you want one of the most habit-forming daily loops on the market with a deep free tier. its built-in courses and speaking practice are the reason millions keep their streaks alive.
pick lrnos if you already have your own course materials and need to actually learn them, in order, and remember them for an exam. lrnos brings the same daily-practice and spaced-repetition discipline to your files, on any subject, in english and egyptian arabic. it is free to start, so you can map your first document and see your path before deciding.
lrnos is free to start with no card, with competitively priced paid plans. duolingo is freemium: a free tier plus paid subscriptions for its premium tiers (figures change, so check their site as of 2026).
