Quizlet vs Knowt: Which Free Plan Is Better for Students?

Why This Comparison Exists: The Free-Tier Frustration

If you are a student studying on a tight budget, you have likely run into Quizlet’s paywalls. Features that used to be free — like Learn mode, practice tests, and games — are now locked behind subscription plans. The free tier has been whittled down to basic flashcards, a limited set of browsing features, and persistent ads. For anyone who cannot or prefers not to pay, this creates a real problem: the tool that many classmates rely on simply no longer works well without a credit card.

Enter Knowt. Built as a direct alternative, Knowt has gained traction by offering a genuinely generous free plan. This article drills into the specific differences between Knowt’s free offering and Quizlet’s free tier — no fluff, no broad survey of five alternatives. (If you want a broader look at several free options, see our Free Quizlet Alternatives: Best Genuinely Free Study Apps by Student Use Case guide.) Here, it is a head-to-head shootout: Knowt vs Quizlet for students who refuse to spend a dime.

Free Plans at a Glance: What You Get for $0

The table below captures the most important differences between Quizlet’s free plan and Knowt’s free plan. The gap is stark.

As the table shows, Knowt provides feature parity with what Quizlet charges for. The only shared free elements are basic flashcards and the presence of ads. Everything else — Learn mode, practice tests, spaced repetition, games — is free on Knowt and paid on Quizlet.

Knowt's Free Features: Unlimited Studying, Spaced Repetition, and More

Knowt’s free Basic plan is remarkably complete. According to the official Knowt Help Center, free users get unlimited flashcards and notes, unlimited access to all study modes — including Learn, Test, Matching, and the flashcard mode itself — plus free spaced repetition. No purchase, no trial, no credit card.

The spaced repetition feature is a standout: you set a target test date, and Knowt’s algorithm (based on the Ebbinghaus Forgetting Curve) automatically schedules your reviews at optimal intervals. This is the same cognitive science that makes Anki so effective, but it is built directly into Knowt’s free tier. On Quizlet, spaced repetition is entirely absent from the free plan and only available on paid subscriptions.

Another major free benefit is the AP Exam Hub. Knowt reports that more than 500,000 AP students use it to access free study guides, flashcards, practice questions, and free-response questions. That entire hub is available at no cost — Quizlet offers nothing comparable on its free tier.

• Unlimited flashcards and notes creation
• Unlimited Learn mode (adaptive, always free)
• Unlimited practice tests and matching games
• Free spaced repetition with test-date scheduling
• Basic AI features (monthly usage limits, reset each period)
• AP Exam Hub: 500,000+ students using free materials

The only catch on the free plan is the presence of ads and a monthly cap on advanced AI capabilities (like AI-generated summaries and assessments). If you want unlimited AI and no ads, Knowt Ultra costs $12.49/month billed annually ($149.99/year) — but for pure studying, the free plan already covers everything most students need.

Quizlet's Free Limitations: Capped Rounds, Locked Modes, and Ads

Quizlet’s free tier is a shadow of what it once was. The official Quizlet upgrade page (Japanese) reveals exactly what paying users get — and what free users do not. On the free plan, you can browse millions of public flashcard sets and create your own basic cards, but the interactive study modes are largely absent.

Specifically, the free tier does not include Learn mode, practice tests, or games like Match and Gravity. To access those, you must subscribe to Quizlet Plus at $2.99/month billed annually ($35.99/year) — but even then, Plus caps Learn mode at 20 question rounds per month and practice tests at 3 per month. For unlimited access, you need Quizlet Plus Unlimited at $3.74/month ($44.99/year). Neither option is free.

• No Learn mode on free plan (requires Plus or Plus Unlimited)
• No practice tests on free plan
• No matching games or other activities on free plan
• No spaced repetition on free plan
• Persistent ads throughout the experience
• Limited AI features on free plan (paid plans required for full access)

In practice, a student using Quizlet for free can only flip through flashcards manually. That is a far cry from the active retrieval, spaced repetition, and self-testing that cognitive science recommends for effective learning. Even the cheapest paid plan (Plus) imposes monthly usage limits that make it impractical for students with multiple classes or exam-heavy study schedules.

Zero-Cost Migration: How to Import Your Quizlet Sets into Knowt

The best part? Switching from Quizlet to Knowt is free and takes less than a minute. Knowt provides two import methods: pasting a public Quizlet set URL or using the Knowt Chrome extension. Here is how it works:

1. Find the public Quizlet set you want to transfer and copy its URL from the address bar.
2. Paste the URL into Knowt’s import field (available when creating a new study set). Knowt automatically converts the entire set, including terms, definitions, images, and formatting.
3. Start studying immediately — your flashcards appear in Knowt with all free study modes unlocked: Learn, Test, Matching, Spaced Repetition, and more.

If you prefer continuous import, the Knowt Chrome extension lets you import with one click while browsing Quizlet. You can transfer entire folders or single sets without leaving your browser.

There is no limit to how many sets you can import, and you never need a credit card to use the free plan. Everything you had on Quizlet — and more — becomes available at no cost.

The Verdict: Knowt Wins for Students Who Won't Pay

After comparing the free tiers side by side, the conclusion is clear: Knowt offers a meaningfully better free experience. For the same price — $0 — Knowt gives you unlimited flashcards, free interactive study modes, built-in spaced repetition, practice tests, matching games, and basic AI features. Quizlet’s free plan leaves you with only basic flashcards and ads, forcing you to pay for nearly every effective study technique.

• Knowt free: Unlimited Learn, Test, Matching, Spaced Repetition, practice tests, AP Exam Hub, and basic AI with monthly caps.
• Quizlet free: Only basic flashcards + ads; all effective study modes require a paid subscription.
• Migration is free and instant: import any public Quizlet set into Knowt in seconds.
• If you later decide you want unlimited AI and no ads, Knowt Ultra ($12.49/mo annual) is still cheaper than Quizlet Plus Unlimited ($3.74/mo annual) when you factor in the study modes you get for free on Knowt.

For any student who needs a full-featured study tool without spending money, Knowt is the straightforward answer. Start by importing your existing Quizlet sets — you have nothing to lose and a complete free study suite to gain.
