Review on schedule
Spaced repetition resurfaces each card right before you’d forget it. Daily review tells you exactly what’s due.
Six tools. One system. Built to make things stick.
Daily review that plans itself
Every card you rate is rescheduled with spaced repetition. Open the app and it tells you exactly which cards are due today — across every subject at once.
A tutor that knows your notes
Not a generic chatbot — it reads your packs and quizzes you back instead of just handing over answers.
Quizzes that explain
Miss a question and the why is explained instantly — pulled from your own notes, not a generic answer.
Hint-first photo solver
Snap a problem and get a nudge before the answer — so you learn the method, not just the result.
Audio recaps
Any pack becomes a 2-minute spoken recap. Review on the walk to class with your hands in your pockets.
Streaks, XP and weak-spot drilling
Every card you miss lands in your mistake journal so you drill exactly what trips you up. Streaks and a friend leaderboard keep you showing up daily.
Other apps generate. Stydra teaches.
Dumping flashcards on you is the easy part. The hard part is making sure you remember them on exam day — that’s what the rest of the system is for.
Explains every wrong answer
Miss a quiz question and Stydra explains why — pulling from your own notes. You leave understanding it, not just knowing you were wrong.
Most apps mark you wrong and move on.
Remembers what you struggle with
Hard-rated cards are tracked and resurfaced. Overdue reviews appear automatically. You always know exactly what needs work.
Most apps show you the same deck every session.
Plans your exam prep
Set your exam date and get a day-by-day schedule built around your actual progress and weak spots.
Most apps generate content and leave the planning to you.

The method — not a marketing claim
Retrieval practice and spaced repetition, built in
Recognition feels like knowing. It isn’t. The thing that reliably moves a grade is pulling the answer out of your own head, being told exactly where you went wrong, and meeting that same gap again a few days later. That loop is the whole product — everything else here exists to serve it.
Say it from memory
Recall Mode makes you type the answer in your own words before you see it. The AI marks what you actually got right — no more nodding along to a card you flipped too fast.
Find out why you were wrong
Miss a quiz question and Stydra explains the specific misconception using your own material, not a generic definition.
Meet your weak spots again
Every rating feeds spaced repetition, so the cards you fumbled come back on schedule — and weak-spots sessions drill only those.

Before you ask.
Something else on your mind? Ask us directly — we read everything.
- Is Stydra really free?
- Yes. The Free plan lets you create study packs with flashcards, step-by-step guides, quizzes, XP and streaks — no credit card, ever. You only upgrade if you want more packs and the advanced tools.
- How is this different from Quizlet or Anki?
- Quizlet makes you build cards by hand and Anki has a brutal learning curve. Stydra generates everything from your notes in seconds — flashcards, guides, quizzes — with built-in spaced repetition, an AI tutor that knows your material, and an interface that actually feels good to use.
- Will it work for my subject?
- Any subject. Paste your notes, upload a PDF or lecture slides, photograph a page of handwriting, or drop a YouTube lecture link — biology, calculus, law, languages, history, you name it. If you can study it, Stydra can build a pack for it.
- Can I cancel anytime?
- Any time, and no questions asked. Open Manage subscription in the app and cancel in the customer portal. You keep everything you’ve made, and your plan stays active until the end of the period you’ve paid for.
- Is my data private?
- Your notes and packs belong to you. They’re never sold and never used to train AI models — they’re only sent to the AI provider that builds your pack. Packs you choose to share are visible only to the people you share them with.
