You've been using Duolingo for months. Maybe years. You've learned enough Spanish to order food with confidence and enough Japanese to embarrass yourself slightly less at karaoke. The streaks work. The XP works. The leaderboard makes you irrationally competitive against strangers you'll never meet.
And at some point, you start wondering: why doesn't this exist for everything else?
You want to learn about psychology. History. How your brain makes decisions. Why some people are persuasive and others aren't. The science behind sleep, habits, and motivation. But when you search for "Duolingo for science" or "Duolingo for history," you get Duolingo's own pages and a handful of apps that look promising in screenshots but feel nothing like the real thing.
We tested dozens of learning apps to find the ones that actually capture what makes Duolingo work: short sessions, real gamification, and a reason to come back tomorrow. Here are the seven best alternatives for people who want the Duolingo experience applied to knowledge beyond languages.
What Makes a Good Duolingo Alternative?
Before the list, let's be specific about what we're looking for. Not every learning app qualifies as a Duolingo alternative just because it has an "XP" counter.
A real Duolingo alternative needs three things. Short sessions you can complete in five minutes or less. Gamification that changes behavior, not just decoration. And a reason to open the app every single day, whether that's streaks, leaderboards, loot, or some other mechanic that makes consistency feel rewarding.
Most learning apps fail on the second point. They add points and badges as an afterthought. The gamification doesn't drive the experience. It's wallpaper. We filtered hard for apps where the game mechanics genuinely make you want to keep learning.
1. NerdSip: The Closest Thing to Duolingo for Everything
Best for: General knowledge across psychology, science, history, philosophy, social skills, health, and productivity.
NerdSip is what you get when you take Duolingo's core insight (gamification creates habits) and apply it to the broadest possible range of knowledge. The library spans 527 courses and roughly 3,100 lessons. Each lesson takes about five minutes. Each one includes a concept breakdown, a visual infographic, a quiz, and a practical takeaway.
The gamification is where NerdSip separates itself from every other app on this list. It runs on an MMORPG-style progression system. You earn XP for completed lessons. You receive loot drops with rarity tiers: 80% Common, 15% Rare, 5% Legendary. There are global leaderboards and daily streaks. The whole thing feels less like an educational app and more like a game that happens to make you smarter.
This is the app that comes closest to the daily Duolingo habit loop for non-language content. The combination of broad topic coverage, genuine gamification depth, and short lesson format is something no other app on this list matches. For a detailed head-to-head, read our NerdSip vs Duolingo comparison.
Gamification depth: High. XP, loot drops, leaderboards, streaks, RPG progression.
Pricing: Free tier available. Plus and Pro tiers for more daily lessons and course generation.
Platforms: iOS, Android.
2. Brilliant: Duolingo for STEM and Logic
Best for: Math, logic, data science, and scientific thinking.
Brilliant takes a different approach from Duolingo. Instead of quick-fire lessons, it uses interactive problem-solving. Each lesson walks you through a concept by having you solve progressively harder problems. The learning is active from the first screen.
The content quality is exceptional. Brilliant's courses on logic, probability, neural networks, and computer science fundamentals are some of the best available on any platform. If your goal is to build quantitative thinking skills, this is the app.
The limitation is scope. Brilliant is laser-focused on STEM. If you want to learn about the Roman Empire, negotiation psychology, or stoic philosophy, you'll need to look elsewhere. It's also more demanding per session than Duolingo. Most lessons take 10 to 15 minutes and require genuine concentration. That's a strength if you have the time and a weakness if you want something you can do while waiting for coffee.
We wrote a full NerdSip vs Brilliant comparison if you're deciding between the two.
Gamification depth: Medium. Streaks, progress tracking, but no loot or leaderboards.
Pricing: Free trial. Premium is $24.99/month or $149.99/year.
Platforms: iOS, Android, Web.
3. Imprint: Visual Learning for Big Ideas
Best for: Psychology, philosophy, and science explained through visual storytelling.
Imprint stands out for its design. Every lesson is built around illustrations and animations that make complex ideas feel approachable. Topics lean toward the "big idea" category: behavioral psychology, decision-making, mindfulness, philosophy. The visual format works especially well for abstract concepts that are hard to learn from text alone.
Lessons take about five minutes. The content is well-written and genuinely interesting. Where Imprint falls short compared to Duolingo is gamification. There's some progress tracking, but no leaderboards, no loot, and no competitive mechanics. The app relies more on content quality than behavioral hooks to keep you coming back. For some people, that's a plus. For people who need the gamification push, it's a gap.
The library is also smaller than NerdSip's, focusing on curated "essentials" rather than trying to cover every topic imaginable.
Gamification depth: Low. Progress tracking and collections, minimal competitive elements.
Pricing: Free trial. Premium runs about $9.99/month or $79.99/year.
Platforms: iOS, Android.
4. Headway: Book Summaries in Bite-Sized Lessons
Best for: Getting the key ideas from nonfiction books in 15 minutes or less.
Headway compresses popular nonfiction books into visual summaries you can read in about 15 minutes. Think Blinkist but with a cleaner interface and better visual design. Books like Atomic Habits, Thinking, Fast and Slow, and The Psychology of Money are distilled to their core ideas with illustrations and key takeaways.
The app has daily reading goals and streaks. The content is well-curated. If your main goal is to absorb the big ideas from popular books without committing to reading each one cover to cover, Headway does this well.
The weakness: it's a consumption tool, not a learning tool. There are no quizzes. No active recall. You read a summary, maybe highlight a passage, and move on. Research on memory is clear that passive reading without retrieval practice leads to fast forgetting. You'll feel smart after reading a Headway summary. Whether you'll remember it in two weeks is another question.
For a deeper dive on this distinction, check out our NerdSip vs Blinkist comparison (the same analysis applies to Headway).
Gamification depth: Low to medium. Reading streaks, daily goals, challenges.
Pricing: Free trial. Premium is about $11.99/month.
Platforms: iOS, Android.
5. Nibble: Trivia-Style General Knowledge
Best for: Learning fun facts across a wide range of topics in a casual, quiz-game format.
Nibble delivers general knowledge in a trivia format. Short daily lessons cover topics like science, history, nature, space, and culture. The approach is lighter and more casual than the other apps on this list. Think of it as learning through curiosity rather than through structured courses.
The app has streaks and daily challenges. The content is genuinely interesting and covers an impressive range of topics. If you want to become the person who always has a fascinating fact to share, Nibble is built for that.
Where it falls short is depth. Nibble gives you facts. It doesn't build understanding. You'll learn that octopuses have three hearts, but you won't understand why. For some people, the trivia approach is perfect. For people who want to build real knowledge on a topic, it's more of a complement than a replacement.
Gamification depth: Medium. Streaks, daily challenges, progress tracking.
Pricing: Free tier available. Premium for ad-free experience and more content.
Platforms: iOS, Android.
6. CuriosityStream: Documentaries for Deep Dives
Best for: Long-form, high-production learning through documentaries and series.
CuriosityStream is the odd one out on this list. It's not a micro-learning app. It's a documentary streaming service. But it deserves a spot because it fills a specific need: when you want to go deep on a topic, not just get the five-minute overview.
The library covers science, technology, history, nature, and society. The production quality ranges from good to excellent. At $2.99/month, it's also far cheaper than most streaming services. If you've ever wished Netflix had more documentaries and fewer reality shows, CuriosityStream is the answer.
The obvious limitation is format. There's no gamification. No quizzes. No daily habit mechanics. You watch a documentary when you feel like it. It's passive entertainment, albeit educational entertainment. Pair it with an active learning app like NerdSip for the best of both worlds: deep dives when you have time, gamified micro-lessons when you don't.
Gamification depth: None. It's a streaming service.
Pricing: $2.99/month.
Platforms: iOS, Android, Web, Smart TVs.
7. Khan Academy: Structured Academic Learning (Free)
Best for: Academic subjects with structured progression, especially math and science.
Khan Academy is the most comprehensive free learning platform on the planet. It covers math from elementary through calculus, plus science, economics, history, and computing. The content is structured like an actual course, with video lessons, practice problems, and mastery tracking.
The platform has added more gamification over the years: points, badges, energy points, and streak tracking. The AI tutor Khanmigo adds a conversational layer for students who need help. For academic learning, especially if you're studying for exams or filling gaps in your formal education, Khan Academy is hard to beat.
The trade-off is that Khan Academy feels like school. That's by design. But it means the sessions are longer, the content is more structured, and the experience is less casual than Duolingo or NerdSip. If you want to brush up on calculus, it's excellent. If you want to learn about behavioral psychology during your lunch break, it's not the right tool.
Gamification depth: Medium. Points, badges, streaks, mastery levels, Khanmigo AI tutor.
Pricing: Free. Khanmigo is $9/month.
Platforms: iOS, Android, Web.

Which One Should You Pick?
The answer depends on what you want to learn and how much time you have.
If you want the closest Duolingo experience for general knowledge: NerdSip. Same short sessions, same addictive gamification, broadest topic range. This is the default recommendation for anyone who typed "Duolingo but for everything" into a search bar.
If you want deep STEM learning: Brilliant. The interactive problem-solving approach is the best available for math, logic, and data science. Expect longer sessions and more mental effort.
If you're a visual learner who wants curated big ideas: Imprint. Beautiful design, well-chosen topics, but less gamification to keep you coming back.
If you want to absorb book knowledge fast: Headway. Great for getting the gist of nonfiction bestsellers. Just know that without quizzes, retention will be lower.
If you want casual trivia-style learning: Nibble. Fun, light, and broad. Better for facts than deep understanding.
If you want long-form documentary-style learning: CuriosityStream. Best value in educational streaming.
If you need structured academic courses for free: Khan Academy. Can't be beaten on price or academic depth.
The reality is that many people use two or three of these together. NerdSip for the daily gamified habit. Brilliant or Khan Academy when you want to go deeper on a specific subject. CuriosityStream on weekends when you have time for a full documentary. There's no rule that says you have to pick just one.
The only wrong choice is going back to scrolling social media instead. For more on that, read our guide on whether a Duolingo for everything actually exists.
