Flashcards that
respect you.
Serious Leitner spaced repetition in a clean app that works fully offline — the core is free and unlimited, with no ads and no dark patterns. See a card, flip it, two buttons, done.
Your cards live in your pocket,
not on our servers.
The whole app works with no connection — study, edit, and organise anywhere. Changes apply instantly, queue up safely, and sync the moment you're back online, with a visible sync status. A dropped connection never loses your work.
- Study on the metro, on a plane, at the cottage with no signal — everything just works.
- After a single online visit, every page and every language loads offline — even screens you've never opened.
- Back online, your changes sync across devices automatically — with a visible “last synced” status.
Spaced repetition you can actually see.
No mysterious algorithm grading you in secret. Plesica uses Leitner boxes 0–8: get a card right and it moves up a box, waiting longer before the next review. Miss it and it drops back to relearn.
Simple two-button reviews
You're not micro-rating every card on a five-point scale. “Forgot” or “Knew it.” That's it.
Box 0 → Box 8
Each box waits about twice as long as the last. Watch a card climb from brand-new to Mastered at box 8.
Forgot it? Same-session relearn
A missed card drops back a box and comes around again before you finish — so a bad guess never becomes a blind spot.
And the product actually works. Here's what's shipped today.
Everything below exists in Plesica right now — not on a roadmap slide. And the whole app is available in 12 languages.
Organise with nestable folders
Build folders inside folders to mirror how a subject really breaks down. Create and edit cards with a clean, fast editor — bold, colors and lists when a card needs structure, and images or audio added by link when text alone isn't enough.
Lossless import & export
Export exactly the folders you pick — or everything — into one JSON file that keeps folder paths and formatting, so a round trip loses nothing. Import it back (or a spreadsheet CSV) with a full preview: missing folders are created, duplicates are flagged, and every row is editable before anything is saved. With Plesica Plus, AI Scan even drafts cards from a photographed page into that same preview — you stay the editor.
Decks from any folders
Tick one or more folders to build a study deck; ticking a folder pulls in its whole subtree. Set direction A→B, B→A, or both, plus daily limits.
Two study modes
“Practice all” shuffles everything with no scheduling pressure. “Daily” runs true Leitner spaced repetition when you want cards to actually stick.
See your progress at a glance
A home overview with your day streak, due-today, studied, and mastered counts, plus per-deck progress. Browse any deck by Leitner box to see exactly what's unseen and what sits where — every card tagged with its box and folder.
Installable PWA, mobile-first
Install it to your phone, tablet, or desktop — or just use it in the browser. Responsive everywhere. Nothing to download from an app store.
The principles we're holding ourselves to — in the open.
We tag every promise honestly. Live means it's true today. Building means we're working on it — and saying so.
The core is free — forever
No trial countdown, no ads, no caps on folders, cards, or decks. The forever-free core is everything you study with — the optional Plus tier only ever adds extras, never takes away what's free now.
No dark patterns
No manufactured urgency, no buried settings, no growth tricks at your expense. Your review screen is for reviewing.
Spaced repetition you can understand
Transparent Leitner boxes 0–8. You can see exactly which box every card is in — no algorithm grading you in secret.
Your data is yours — export it any time
Free export is live today: take your entire collection — or just the folders you choose — as one JSON file, cards with their folder paths and formatting included. Older CSV exports still import. Your data is never locked in.
Works offline. Syncs across devices.
The whole app works offline — study, edit and organise with no connection. Your changes queue up and sync across your devices when you're back online, with a visible “last synced.” A dropped connection never loses your work.
A fair-pricing promise
Plesica Plus is live — and the fairness rules shipped before we asked for a cent: prices up front, no hidden trials, the renewal date always visible, and cancelling is one click — right in the app, never “contact support”. It's all public in our Pricing & Refund Policy.
Plesica is a young, independent project. You won't find invented star ratings, user counts, or testimonials here — faking social proof would betray the whole point. See exactly where things stand in the changelog.
The core is free forever. Plus is optional.
The free core stays free — every card, folder, deck and study mode. The optional extras that cost real server money are live now: Plesica Plus and a one-time lifetime supporter tier — priced fairly, and impossible to get trapped in.
Everything you use today
Unlimited cards and folders — rich text with images & audio by link included — both study modes, Leitner spaced repetition, full offline mode, sync across devices, and lossless JSON import & export (your old CSVs still import). This is the core — it never moves behind a paywall.

A small monthly or yearly subscription for the extras that cost us real money to run. First up: AI Scan — photograph a page, get cards drafted into the right folders, with €1 of AI usage included every month and an optional +€1 top-up. Cancel in one click, any time.
Lifetime supporter
One payment, every Plus feature forever. For people who want an independent, honest flashcards app to exist.
The fair-pricing rules are built into the app: the price and renewal date always visible, no hidden trials, payment and card details managed right in the app, and cancelling is one click — never “contact support”.
