Anki vs Duolingo: Which Is Better for Vocabulary?
Two Philosophies
Duolingo gamifies language learning with streaks, XP, and bite-sized lessons. Anki gives you a blank canvas and a spaced repetition algorithm. They couldn't be more different - and that difference matters depending on what you're trying to achieve.
Duolingo: The Casual Path
Duolingo's strength is accessibility. You download the app, pick a language, and start learning immediately. The gamification keeps you coming back, and the structured course means you never have to think about what to study next.
But there's a tradeoff. Duolingo chooses what you learn and when. The vocabulary is often topic-based rather than frequency-ordered, which means you might spend weeks on food vocabulary before learning words you'll actually encounter every day. And once you've completed a lesson, you have limited control over how often you review it.
Best for: Absolute beginners who need motivation to start and maintain a daily habit.
Anki: The Power User's Tool
Anki has one of the best spaced repetition algorithms available. You can create your own cards or download community-shared decks, customize review intervals, and build exactly the study system you want. There are some great decks out there.
The pain point isn't that good content doesn't exist - it's the experience of using it daily. Anki's interface hasn't meaningfully changed since the 2000s. The desktop app looks like a Windows XP utility. The mobile apps feel dated. Basic tasks like changing a font size or tweaking card layout require digging through nested menus, config screens, and sometimes editing HTML templates. Even with a good deck, the day-to-day experience of reviewing cards feels clunky and unpleasant compared to anything built in the last decade.
For a tool you're supposed to open every single day, that matters more than most people realize. Motivation erodes when the tool itself feels like a chore.
Anki's flexibility comes at the cost of significant setup time.
Best for: Disciplined learners who enjoy optimizing systems and don't mind the setup overhead.
Where Both Fall Short
Neither tool optimizes for the fastest path to comprehension:
- Duolingo teaches vocabulary in an arbitrary order dictated by its course designers
- Anki relies on community decks of varying quality, with no built-in frequency ordering and an interface that feels stuck in 2006
- Neither automatically prioritizes the most common, highest-impact words
Neither gives you a polished, frequency-ordered experience out of the box.
The Third Option
What if you could combine Anki's spaced repetition with Duolingo's zero-setup experience - and add frequency-ordered vocabulary on top?
That's what Vocabcraft does. Every word is ordered by real-world frequency. The spaced repetition algorithm handles review scheduling. AI generates mnemonics to help words stick. And you never touch a settings page or import a deck.
