Apps Like Duolingo for General Knowledge: What Actually Works

TL;DR
Duolingo is sticky because the lesson is tiny, the progress is visible, and the streak makes today matter. No general-knowledge app copies that loop perfectly, but several get close in different ways. Imprint is the most visual, Headway and Blinkist are book-summary engines rather than lesson engines, Deepstash is a feed of ideas, and Elevate and Lumosity train skills rather than teach facts. MindSnap, which is our app, aims at story-driven two-minute lessons with a daily habit. Disclosure: MindSnap is ours, so weigh our verdict accordingly.
The request I get most often, from friends and from readers, is oddly specific. They do not want a language. They want the feeling of Duolingo attached to something else: history, science, art, the kind of general knowledge that makes you slightly better company at dinner. They want the small green box that says you did the thing today.
I have tested a lot of these apps, uninstalled most of them, and kept a small number for longer than a month. Here is what I think is actually going on, and which apps come closest.
Why the Duolingo loop works in the first place
Three things do the heavy lifting, and none of them are about language.
- The unit is small enough that refusing feels silly. A lesson is measured in minutes, not chapters, which is the same reason the two-minute rule works on chores.
- Progress is visible. You can see a skill fill up, which turns invisible learning into something with a shape.
- The streak converts a vague intention into a daily appointment, and losing it feels like a real cost.
Notice that only the first item has anything to do with teaching. The other two are habit design. That matters when you go shopping, because plenty of knowledge apps have wonderful content and no loop, and plenty have a loop wrapped around content you do not care about. If you want the fuller framework for judging that, I wrote it up in how to choose a learning app.
The honest survey
MindSnap: story-driven daily lessons
Disclosure first: MindSnap is our app, so treat this section as the interested party talking. The design bet is that a two-minute lesson lands better as a story than as a bulleted summary, so the daily unit is a narrative episode rather than a fact sheet. There are five flagship story-driven collections plus unlimited topics, so you are not boxed into a fixed syllabus. The Turning Points feature is the clearest example of the approach: you stand inside a historical decision and choose, then find out what actually happened. Pricing is $9.99 a month or $44.99 a year, with a free daily fact if you want the habit without the subscription. Where it falls short: if you want drills, scores and a competitive leaderboard, this is not that.
Imprint: the most visual option
Imprint is the closest thing to Duolingo's lesson feel in the knowledge space. Illustrated cards, short units, clear progression through a topic. If you learn happily from diagrams and you like a polished interface, it is an easy recommendation. The limitation is depth: the visual format is excellent at introducing a concept and less suited to sitting with a long argument.
Headway and Blinkist: summaries, not lessons
Both take nonfiction books and compress them. They are genuinely useful for deciding what to read and for extracting a framework fast. But a summary is not a lesson: there is no retrieval, no quiz, no spacing, so what you keep depends entirely on what you do afterwards. Headway leans harder into the daily-habit framing, Blinkist into library breadth. If your goal is coverage of business and self-improvement titles, they are the right shelf. If your goal is remembering things, treat them as reading, not studying. That distinction is the whole subject of microlearning versus book summaries.
Deepstash: a feed of ideas
Deepstash is closer to a curated scroll than a course. You collect small insights, save them, and build a personal library. For people who like serendipity and are honest about wanting something to read in a queue, it works. It is the least structured of the group, which is a feature if you dislike syllabuses and a bug if you want to finish something.
Elevate and Lumosity: skills, not knowledge
These come up constantly in this search, and they are answering a different question. They train tasks: reading speed, mental maths, attention games. The daily loop is strong and the sessions are short, which is why they feel Duolingo-adjacent. But you will not walk away knowing what caused the Dutch Golden Age. The evidence on whether trained tasks transfer to general ability is much weaker than the marketing implies, which I went through in brain training versus real learning.
What to match to what
| If you want | Start with |
|---|---|
| A narrative daily habit | MindSnap (our app) |
| Illustrated concept lessons | Imprint |
| Book frameworks fast | Headway or Blinkist |
| Serendipitous ideas to save | Deepstash |
| Short cognitive drills | Elevate or Lumosity |
The mistake almost everyone makes
People shop for content when they should be shopping for a loop they will not resent on day nine. I have abandoned apps whose material I admired, and kept apps whose material was merely good, purely because one of them fit into an existing gap in my morning and the other demanded a new one.
So test in that order. Pick the app whose daily unit is small enough that a bad day cannot break it. Attach it to something you already do without deciding: kettle, commute, the walk back from school drop-off. Then look at whether the subject matter still interests you in week three, because novelty flatters everything in week one.
And be suspicious of your own streak. A streak is a scaffold, not the goal. If protecting it turns into tapping through a lesson at 11:58pm while absorbing nothing, the number has quietly replaced the learning. Break it deliberately once and see whether you come back. The apps worth keeping survive that test.
Where to start if you want one recommendation
If you specifically miss the Duolingo rhythm and want general knowledge, try Imprint and MindSnap in the same week, on the same trigger, and keep the one you actually open unprompted on day four. Ours is the story-first option, theirs is the diagram-first one, and that preference is genuinely personal. If instead your reading list is the problem rather than your memory, a summary app will serve you better than either. Browsing the topics available is a decent way to check whether the subject range matches your curiosity before you pay for anything.
Shop for the loop you will keep, not the library you admire.
