Every few years a shiny new flashcard app shows up, raises a pile of venture money, and quietly paywalls the features that used to be free. Anki has been sitting in the corner since 2006, completely free, doing the same unglamorous job better than all of them. Medical students memorize thousands of drug interactions with it. Language learners grind through entire vocabularies. It’s ugly, it’s confusing at first, and it’s the single most effective study tool I know.
This guide does two things: explains why Anki works (the memory science, in plain language), and walks you through setting it up so you’re actually studying within an hour instead of watching tutorial videos all weekend.
Why flashcards work: your brain is a leaky bucket
Here’s the uncomfortable truth about learning: you forget most of what you study within days. Hermann Ebbinghaus measured this back in the 1880s — the famous forgetting curve — and modern research keeps confirming it. Cramming feels productive because recognition feels like knowledge. It isn’t. 
Spaced repetition is the fix. Instead of reviewing everything every day, you review each fact right before you’re about to forget it. Easy cards show up rarely; hard cards come back soon. Over weeks, the intervals stretch from days to months, and the knowledge moves into long-term memory. We’ve covered the full science in our spaced repetition deep-dive — the short version is that it’s one of the most replicated findings in learning research.
Anki is simply the best free implementation of this idea. Its scheduler decides when you see each card; your only job is to show up and answer honestly.
Getting set up: the 20-minute version
1. Download the desktop app. Go to apps.ankiweb.net and grab the version for your computer. It’s free on Windows, Mac, and Linux. Don’t start with the phone app — the desktop version is where you build cards comfortably.
2. Create a free AnkiWeb account. Inside the app, go to Tools → Preferences → Syncing and sign up. This gives you free cloud sync across every device, which matters more than it sounds — you’ll do most reviews on your phone, in dead time between classes.
3. Make your first deck. Click “Create Deck” at the bottom and name it something specific, like “Spanish – Unit 4” rather than just “Spanish.” Small, focused decks are easier to maintain than one giant pile. You can always reorganize later with subdecks.
4. Add cards the right way. Click into your deck, hit “Add,” and you’ll see the default note type: Basic (front/back). Two rules that separate good cards from useless ones:
- One fact per card. “What are the symptoms of diabetes?” is a terrible card — you’ll memorize the list as a blob and forget half of it. Split it: one card per symptom.
- Make the front a real question. “Mitochondria” on the front and a paragraph on the back just trains you to recognize the word. “Which organelle produces most of the cell’s ATP?” forces actual recall.
There’s also a Cloze note type (fill-in-the-blank), which is brilliant for sentences: “The capital of Australia is {{c1::Canberra}}.” If you’re studying from textbooks, cloze cards let you turn highlighted sentences into flashcards in seconds.
The daily routine that actually works
Here’s where most beginners go wrong: they add 100 new cards on day one, drown in reviews by day four, and quit. Anki rewards restraint.
- Start with 10–20 new cards per day. You can raise this later. Reviews of old cards always come first — the app handles the order automatically.
- Do reviews every day, even if it’s just 10 minutes. Spaced repetition only works if the spacing is real. Skipping three days and bingeing doesn’t give you the same memory benefit. This is the same consistency principle behind building a learning habit that sticks.
- Be brutally honest with the Again/Hard/Good/Easy buttons. If you hesitated, it’s not “Good” — it’s “Hard” or “Again.” Lying to the scheduler just means you’ll forget the card later. The algorithm can only help you if you give it true data.
- Keep sessions short. 15–25 minutes of focused review beats an hour of glazed-over clicking. If your attention drifts, take a real break — our guide to effective study breaks explains why.
A realistic expectation: after a month of daily reviews, you’ll have a few hundred cards in circulation and reviews will take 15–30 minutes a day. That’s the maintenance cost of genuinely knowing things long-term.
Shared decks: the shortcut with a catch
One of Anki’s superpowers is its library of shared decks — thousands of pre-made sets covering medical school material, language vocab, law, and more. In the app, click “Get Shared” (or browse AnkiWeb) and search your topic.
The catch: quality varies wildly. A deck made by a careful med student with 10,000 downloads and recent updates is gold. A deck uploaded in 2014 with no description is a gamble. Before committing to a big shared deck:
- Check the ratings and download count.
- Preview 20–30 cards. Are they atomic (one fact each)? Are the answers correct?
- Accept that you’ll still want to edit, suspend, or delete cards that don’t fit how you think.
Here’s my honest take: for languages and standardized exams, shared decks save enormous time. For anything conceptual — where you need to understand, not just memorize — making your own cards is part of the learning. Writing the card forces you to decide what’s actually important.
The FSRS upgrade most people miss
A quick technical note for the curious: Anki added a newer scheduling algorithm called FSRS in 2023, which adapts to your personal memory patterns better than the older default. Most users never discover the setting. You don’t need to touch it as a beginner — but once you’re a few months in, searching “Anki FSRS” will find you a five-minute setup guide that measurably improves scheduling. File it under “later.”
What it costs (refreshingly simple)
- Desktop (Windows/Mac/Linux): free, forever.
- AnkiWeb (browser): free, including sync.
- AnkiDroid (Android): free and open-source.
- AnkiMobile (iPhone/iPad): around $24.99, one-time purchase — the only paid version, and the developer has said it funds the free ones.
So your total cost of the most effective memorization system ever built is somewhere between zero and twenty-five bucks. Compare that with subscription flashcard apps charging monthly, and the choice gets easy.
Anki alongside your other tools
Anki doesn’t replace your notes, your textbooks, or your lectures — it handles one job: making facts stick. A study setup that works well looks like this: learn the concept properly first (lecture, reading, practice problems), then convert the facts worth keeping into cards. Definitions, vocabulary, formulas, dates, classifications — if it’s a discrete fact you’ll need in three months, it belongs in Anki.
What doesn’t belong: entire paragraphs, “understand X” cards, or anything you could look up in five seconds during real work. Anki is for the load-bearing facts — the ones that need to be in your head, not on a screen. Invest the card-making effort where the payoff is, and don’t gold-plate the rest.
Beginner mistakes (I made all of these)
Mistake 1: Adding too many cards. Enthusiasm is the enemy. Twenty new cards a day becomes 200 daily reviews within a month. Start small.
Mistake 2: Making cards too complex. If a card takes more than 10 seconds to answer, split it. Long cards get skipped mentally even when you click through them.
Mistake 3: Only studying what you already know. It’s tempting to breeze through easy cards and dread the hard pile. The hard pile is the whole point — that’s where the learning happens.
Mistake 4: Treating Anki as the entire study system. Flashcards are for facts and vocabulary, not understanding. Pair Anki with deeper techniques — explaining concepts in your own words, for instance. Our guide to reviewing and consolidating what you learned covers how to combine tools instead of relying on one.
Who Anki is (and isn’t) for
Anki shines when you have volume: hundreds of vocabulary words, anatomy terms, formulas, dates, definitions. Language learners in particular get absurd value from it — if that’s you, pair it with the strategies in our language learning guide.
It’s overkill if you just need to remember a dozen things for next week’s quiz — a paper list works fine there. And if the interface makes you want to throw your laptop, that’s fair; it looks like software from 2006 because parts of it are. Push through the first week. The ugliness fades; the memory doesn’t.
The bottom line
Install it today. Make 20 cards from whatever you’re currently studying. Review them tomorrow — it’ll take six minutes. Do that for two weeks and you’ll understand, in your bones, why this plain, free, stubbornly unsexy app has outlasted every competitor. Your future self, the one who actually remembers things, will thank you. 🧠
