How to make your own flashcard app (spaced repetition, no code)
~6 minutes · no code · free to start
Anki is powerful and looks like tax software. The flashcard apps that look nice charge monthly for what is, at heart, a stack of cards that flip. Perfect job for Kyntra.
This one has the feature that actually makes flashcards work — cards you miss come back sooner — plus a paste-to-import mode, because typing cards one by one is why people quit.
What you'll end up with
- ✓Decks and cards with front/back, tap or press space to flip
- ✓'Knew it / again' grading with simple spaced repetition
- ✓Paste a whole list of 'front - back' lines to create cards in bulk
- ✓Progress per deck: mastered, due today, study streak
The five steps (same for every app)
- 1
Describe it
Type what you want in plain English — like you'd explain it to a friend. No technical words needed. Every guide below gives you a ready-made description you can use as-is or edit.

Check the plan
Kyntra replies with a short plan in plain English: what it understood and what it's about to build. If it got something wrong, just say so. Happy? Hit Approve. (You can switch on Auto later to skip this step.)

Watch it build
About a minute later your app appears in the preview panel — a real, working app, not a mockup. Click around in it right away.

Ask for changes
This is where Kyntra is different from hiring anyone: changes are just sentences. "Make it blue." "Add a delete button." "That chart is confusing, make it simpler." Each change takes about a minute, and every version gets a quality grade in the header — Kyntra checks its own work for the mistakes AI builders usually make.
- 5
Publish it
One click on Publish gives your app a real web address you can send to anyone or open on your phone. Change something later? Publish again — same address, new version.
Your ready-made description
This is the exact text the button below pastes for you — read it, edit anything, or use it as-is.
A flashcard study app. I can create decks, and cards with a front and back. Study mode shows one card at a time — tap to flip, then mark 'knew it' or 'again'; cards I miss come back sooner (simple spaced repetition with three boxes). Show per-deck progress: cards mastered, due today, current study streak. Include a quick-add mode where I paste many 'front - back' lines at once and it creates all the cards. Seed one example deck (Spanish basics) so study mode works immediately. Clean, calm, keyboard shortcuts for flip and grading.
Make it yours — things to say next
After the first build, changes are just sentences in the chat. For example:
You say: “Add a cram mode that ignores the schedule and shuffles everything”
→ Night-before-the-exam mode
You say: “Read the front of the card out loud”
→ Pronunciation practice for language decks
You say: “Add image support on the back of cards”
→ Diagrams for anatomy, maps for geography
You say: “Make the 'again' button less punishing — soft orange, not red”
→ Kinder failure. Better habit.
Common questions
Can I import my existing cards?
If you can get them into 'front - back' lines (any spreadsheet exports that), paste them into quick-add and they all become cards at once.
Do I need to know how to code?
No. You describe, Kyntra builds. You never have to read or touch code — though it's all there if you're curious.
Is it really free?
Yes — free to start, no card. The free plan includes 5 apps and 25 builds a day, which is plenty to build and polish something real.
How do I know the app is any good?
Every version is audited by Kyntra's 17-check quality engine — the same kind of review a senior engineer would do — and stamped with a letter grade you can see in the workspace header.
Five minutes from now, this exists.
