Learn it once.
Remember it for good.
Docki pairs every deck with a Document — the lesson — and Flashcards to remember it. AI writes the cards, explains what you select, and a proven scheduler brings each one back right before you’d forget it.
- Vocabulary & knowledge decks
- Phone, tablet & desktop
- Imports Anki decks
See Docki in action
The real app, on the web and on your phone — from reading a lesson to remembering it.
Active recall + spaced repetition
The two best-studied ways to remember for the long term, built into every deck.
Each dot is a review. Memory resets to full and then fades more slowly than before.
Retrieve, don’t reread
Every card asks before it tells. Pulling the answer out of memory is what makes it stick — rereading only feels like learning.
Right before you forget
The FSRS scheduler learns how well you know each card and brings it back just as it starts to fade. Each review keeps it longer.
Honest self-grading
Again, Hard, Good or Easy — one tap or one key. Type the answer when you want to be strict with yourself.
Everything you need to learn and keep it
From the first lesson to the hundredth review.
Vocabulary decks
Pick the language you learn and the one you think in. Each word becomes a card with a photo, meaning, pronunciation with audio, an example sentence and its translation — filled in for you.
AI writes your cards
AI reads the deck’s Document and drafts flashcards and quizzes, each linked to the section it came from. It also checks what your cards still miss.
Select to learn
Select any passage of a Document to have it explained, simplified or illustrated with an example — or add it straight to a card.
Edit with AI
Turn a paragraph into a diagram or a table, rewrite it more clearly, make bullet points or fix the spelling. Review the change before it lands.
Every device, in sync
Your decks, documents and progress are saved to your account and follow you from laptop to phone. Study on the bus, edit at your desk.
Swipe & smooth animations
On a phone, swipe a card right or left like a deck of cards; on a desktop, use the keyboard. Cards flip, fly and spring back smoothly.
Anki integration
Bring the decks you already have: import .apkg and .colpkg packages with their images and audio, and choose whether each becomes a knowledge or a vocabulary deck.
Read aloud
Natural voices read your Documents and play the pronunciation when a vocabulary card flips.
Type the answer
Type what you remember and see exactly what you got right, letter by letter.
Quizzes
Check a whole lesson at once with a quiz AI writes from the deck’s Document.
Rich cards
Bold, colors, lists, code, images, audio, video and Mermaid diagrams — on both sides of a card.
Progress you can see
Today’s queue and stats show what’s due, what you’ve learned and how your memory is growing.
Select a passage. Ask about it. Keep it.
Your Document is the source of truth. AI works on the part you point at, and you decide what stays.
How retrieval strengthens memory
Reading a page again feels productive, but it mostly builds familiarity. Retrieval practice — recalling information without looking — forces the brain to rebuild the path to a memory, and every rebuild makes the next one easier. Spacing those attempts out over growing intervals turns short-term effort into long-term knowledge.
When you try to recall something, your brain has to search for it and reconnect the pieces. That effort is the workout: the link gets stronger each time, so the memory comes back faster and lasts longer.
Three steps, then a habit
Add a Document
Write a lesson, paste your notes or a chapter, or import an Anki deck. For vocabulary, just list the words.
Let AI make the cards
Generate flashcards and quizzes from the Document. Edit anything — every card keeps a link to where it came from.
Review a little every day
Recall, grade yourself, move on. Docki schedules each card so a few minutes a day keeps everything fresh.
Your decks follow you
One account, every device — and the Anki decks you already have.
Multiple devices
Changes sync to your account as you make them. A layout made for phones, with big buttons and swipe gestures.
Anki integration
Import .apkg and .colpkg packages — cards, images and audio — keeping their deck structure. Turn them into vocabulary decks to get photos, pronunciation and examples.
Start remembering what you learn.
Write a lesson, let AI turn it into cards, review a few minutes a day. Docki handles the rest.
