Turning notes into cards: speed and accuracy
This is the main event for any "Gizmo vs Knowt" decision.
How to test it fairly
Don't trust a TikTok demo. Do this:
- Grab one real page of your notes. Something with definitions, a formula and a list.
- Make a deck from it in Knowt.
- Make a deck from the same page in Gizmo.
- Score each deck: how many cards were right, how many were vague, how many included stuff that wasn't in your notes.
What to look for
- Coverage. Did every key term become a card?
- Accuracy. Did the AI add anything you never wrote? That's a red flag for exams.
- Card size. One fact per card is ideal. Giant paragraph cards are hard to review.
- Cleanup time. If you spend 20 minutes fixing a 5-minute deck, that's not a win.
Is Knowt AI? Is Gizmo AI?
Yes and yes. Both use AI to generate cards, summaries or questions from what you give them. The question is how much you trust the output, and that's why the test above matters.
Learn mode, quizzes and spaced review
Knowt's study modes
Knowt pitches a free Learn mode, flashcards, matching and practice tests, which is a big reason people search "is Knowt better than Quizlet." If you loved Quizlet Learn and hit a paywall, Knowt is the obvious place to land. We go deeper in our free Quizlet alternatives with Learn mode guide.
Gizmo's spaced review
Gizmo leans hard into spaced repetition with a game-like loop. If streaks keep you showing up, that's a feature. If losing a "life" makes you want to throw your phone, maybe not.
The part nobody tells you
Learn modes are great inside a session. But exams test what you remember next week and next month. The trick is bringing each card back right before you'd forget it, with longer gaps as you get it right. Doing that by hand across 300 cards and five classes? Not happening.
FlashDeck does that scheduling for you. Every day it shows only the cards you're about to forget, about ten minutes' worth. Tap Knew it or Missed it: a miss comes back tomorrow, a hit waits a day, then three days, then longer. Build my study plan
What is actually free
Is Knowt free? Is Knowt completely free?
Knowt markets a big free plan, and a lot of its core tools have been free. Some extras may sit behind a paid tier, and that line moves. Before exam season, check:
- How many AI generations you get free.
- Whether Learn mode and practice tests have limits.
- Whether there are ads.
Is Gizmo free?
Gizmo has a free tier, but the game-style limits and AI usage caps can push you toward paying, especially when you're making lots of decks at once. Check the current limits in the app.
Is Knowt safe and is Knowt legit?
Knowt is a real, widely used study app, not a scam. As with any app, read the privacy policy, don't upload anything you wouldn't want stored, and use a strong password. If you're under 18, loop in a parent if an app asks for payment details.
Best for AP, GCSE or college
AP and SAT prep (US)
For AP units, both work if you build cards from your own class notes. People ask "is Knowt good for SAT," and it can help with vocab and formulas, but the SAT is mostly reasoning, so practice tests matter more than cards there.
GCSEs and A-levels (UK) / grade 11 and 12 (Canada)
Your exam board spec is the boss. Make cards from your revision guide, not random shared sets. Gizmo's daily-review loop works nicely for the long revision (UK) / study (US) stretch before May.
College and uni
Lecture slides and readings are where AI generation saves the most time. Either app can work, but accuracy matters more here, so run the test above with a real lecture.

Our pick and when to switch
- Choose Knowt if you're coming from Quizlet, want many modes and care most about free.
- Choose Gizmo if you want a daily habit with streaks and spaced repetition baked in.
- Switch if you notice you're spending more time making and fixing cards than reviewing them, or if you keep "studying" without knowing what you actually forgot.
That last one is the sneaky problem. An app can feel productive while you're mostly rereading cards you already know.
Ten minutes a day, only the cards that matter
Whatever you pick in Knowt vs Gizmo, the goal is the same: review what you're about to forget. With FlashDeck you paste your notes or a PDF, get cards from only what you pasted, delete the ones you don't need, and get a short daily review from tomorrow. It's $4.99 a month, with two-tap cancel and a 7-day refund.
