I spent the last month testing every popular flashcard app I could find. Some were great. Some charged $20/month for features you can get elsewhere for $5. Here's what I learned.
Look, I get it—you're busy. You don't have time to download 10 apps and figure out which one doesn't waste your time or money. So I did it for you. I tested these apps with actual study materials: a 40-page biology PDF, some handwritten notes I photographed, and a recorded lecture. Here's how they compared.
Quick Answer
- Want free + powerful? Anki. Ugly but unbeatable.
- Want AI without overpaying? Laxu AI. $5/month does what $20/month apps do.
- Have money to burn? StudyFetch. Popular, but honestly overpriced.
- Studying for MCAT/LSAT? Brainscape. Good pre-made decks.
What actually matters in a flashcard app
After testing all these apps, here's what I actually cared about:
- Does it have spaced repetition? This is non-negotiable. If the app doesn't space out your reviews intelligently, you're wasting time. Here's why spaced repetition matters.
- How fast can I make cards? I have a 50-page PDF. I'm not typing 200 flashcards by hand. Either give me AI or give me a really fast manual system.
- Can I study on my phone? I do most of my studying on the bus. No mobile app = no deal.
- Can I get my cards out? If I spend hours making cards, I want to own them. Export to Anki format is ideal.
The apps I tested
1. Anki - The OG (free, ugly, powerful)
Every med student I know uses Anki. There's a reason for that—it works. The spaced repetition algorithm is the best out there, and there are literally millions of shared decks you can download for free.
But here's the thing: Anki looks like it was designed in 2005 (because it was). The learning curve is steep. I spent an hour just figuring out how to set it up properly. And if you want AI to help make cards? You'll need to install add-ons, and even then it's clunky.
What I liked: Free on desktop and Android. The spaced repetition actually works—I remembered things weeks later. Tons of add-ons if you're into customization. Huge library of shared decks (someone's already made cards for your textbook, probably).
What I didn't like: Took me forever to figure out. The iOS app costs $25 (yes, really). No AI unless you hack together some add-ons. The interface... let's just say it has "character."
Who should use it: If you're in med school, law school, or learning a language long-term, just learn Anki. The time investment pays off. For everyone else, there are easier options now.
Cost: Free (but $25 on iPhone)

2. StudyFetch - Big name, big price tag
StudyFetch is everywhere on TikTok and Instagram. 7 million students use it. The AI is solid—I uploaded my biology PDF and it generated decent flashcards in about a minute.
But then I saw the price: $19/month. For flashcards.
Look, the app is good. The AI works. But when I found out other apps do the same thing for $5/month, I felt like I'd almost gotten ripped off. StudyFetch is banking on their brand and marketing, not on being the best value.
What I liked: The AI actually understood my PDF. Multiple study modes. Slick interface. The quiz feature is nice.
What I didn't like: $19/month is steep for a student budget. The free tier is basically useless—you hit limits fast. No way to try it for a week without committing.
Who should use it: If your parents are paying and you like the interface, go for it. Otherwise, keep reading.
Cost: $19/month (or $8/month if you pay for a full year upfront)
3. Laxu AI - Same features, quarter of the price
Here's what surprised me: Laxu AI does basically everything StudyFetch does, but costs $5/month instead of $19.
I uploaded the same biology PDF. Got flashcards in about a minute. The quality was comparable—maybe even slightly better because it also generated a summary and quiz questions alongside the cards.
The thing I actually appreciated: you can also make your own cards manually. So when the AI generates 25 cards from your PDF, you can add 5 more that phrase things the way your professor likes to ask questions. That flexibility is underrated.
What I liked: AI works on PDFs, photos of notes, even audio recordings of lectures. You can create manual cards too (like Anki, but the interface doesn't make you want to cry). Exports to Anki if you ever want to switch. Has an AI tutor that answers questions about your study materials—actually useful when you're stuck on a concept. And the price—$5/month is reasonable, and there's a $2/week trial if you just need it for finals.
What I didn't like: It's newer, so there's no big library of shared decks like Anki has. You're mostly making your own cards (or having AI make them).
Who should use it: Anyone who has PDFs, lecture slides, or notes they want to turn into flashcards without spending $20/month or typing everything manually. Honestly, this is what I'd recommend to most students.
Cost: First upload free. Then $1.99/week, $4.99/month, or $39.99/year.
Try uploading a PDF — it's free for your first one, no credit card needed.
4. Turbo AI - Another $20/month option
Turbo AI is similar to StudyFetch. AI flashcard generation, quizzes, the whole package. They claim 5 million users.
The AI worked fine when I tested it. But at $19.99/month, I had the same reaction as with StudyFetch: why am I paying this much when cheaper alternatives exist?
What I liked: Clean interface. AI generates decent cards. Has progress tracking and analytics.
What I didn't like: $20/month. That's $240/year for flashcards. No cheap trial option. If you're paying monthly, you could literally get Laxu AI for 4 months for what Turbo charges for 1.
Who should use it: If you've tried Laxu AI and StudyFetch and somehow neither worked for you, Turbo AI is another option. But honestly, they're all doing the same thing at this point.
Cost: $19.99/month (or $9.99/month billed yearly)
5. Brainscape - Good for standardized tests
Brainscape is different from the others. Instead of AI, their selling point is professionally-made flashcard decks for things like MCAT, LSAT, GRE, and bar exam prep.
You rate each card 1-5 based on how well you knew it, and it adjusts the repetition accordingly. Simple and effective.
What I liked: The pre-made decks are actually good quality. Interface is clean. The confidence-based system makes sense.
What I didn't like: If you're not studying for a standardized test, the value proposition drops. $10/month adds up. No AI to help you make your own cards.
Who should use it: MCAT, LSAT, or bar exam students who want ready-made decks without making their own cards.
Cost: Free tier available, $10/month for Pro
Comparison table
| App | Best For | Monthly Price | AI Features | Value Rating |
|---|---|---|---|---|
| Anki | Long-term memorization | Free (iOS $25) | Add-ons only | ★★★★★ 5/5 |
| Laxu AI | AI + manual cards | $4.99/mo | AI + manual | ★★★★★ 5/5 |
| StudyFetch | Full AI suite | $19/mo | Core feature | ★★★★★ 3/5 |
| Turbo AI | AI study tools | $19.99/mo | Core feature | ★★★★★ 3/5 |
| Brainscape | Test prep | $10/mo | No | ★★★★★ 3/5 |
The price difference is wild
I genuinely don't understand why StudyFetch and Turbo AI charge $19-20/month when Laxu AI does the same thing for $5. They all upload PDFs, they all generate flashcards with AI, they all have quizzes. The only difference is one costs 4x more.
If you want AI flashcards, try Laxu AI first. You can always switch to a more expensive option if you somehow find it lacking.
So which one should you actually use?
After testing all of these, here's my honest take:
If you're broke and have time: Learn Anki. Yes, it's ugly. Yes, it takes a while to figure out. But it's free and it works. Med students have been using it for years for a reason.
If you have PDFs/notes and want AI to do the work: Use Laxu AI. It's $5/month and does everything the $20/month apps do. I uploaded the same PDF to all three AI apps and couldn't tell a meaningful difference in the output. Why pay more?
If you're studying for MCAT/LSAT/GRE: Check out Brainscape. Their pre-made decks for standardized tests are actually good, and you won't have to make your own cards.
If someone else is paying: StudyFetch or Turbo AI are fine. They work. They're just expensive.
My recommendation
Here's what I'd do if I were starting over: try Laxu AI's free upload first. Throw a PDF at it, see if the flashcards it generates are useful. If yes, $5/month is pretty reasonable for something that saves you hours of typing.
If you hate it, Anki is always there—free and powerful, if you're willing to learn it.
What I wouldn't do: pay $19/month for StudyFetch or Turbo AI when cheaper alternatives exist. That's $228/year for flashcards. Come on.
