New: dynamic cards that adapt as you learn
Flashcards that look the way you write them
Rcll is a flashcard app for people who learn with Markdown, code and math. Write cards the way you think, and study them with spaced repetition and dynamic cards that hide more of the answer as you improve.
Features
Built for what you actually study
Formulas, code, vocabulary or definitions: Rcll keeps your cards readable and schedules them for you, so you spend your time remembering, not managing.
Dynamic cards
Write an answer as a list or mark {{gaps}}. Rcll hides some of it while you study, and more as you get better.
Spaced repetition
FSRS, a modern scheduler, brings each card back right before you would forget it. You set how much you want to retain.
Routines
Collections defined by rules: tags or text. New cards that match join on their own. Study with spaced repetition or a fresh shuffle.
Cards from your PDFs
Drop in lecture notes and get draft cards to edit, keep or skip. AI only runs when you ask, and suggests tags on request.
Math, code and tables
Markdown with LaTeX, fenced code and tables, rendered on both sides exactly the way you typed it.
Progress you can see
A daily goal, your streak, a year of activity and your recall rate, all on one page.
Phone and keyboard
Install Rcll to your home screen and swipe to answer, or study at your desk without touching the mouse.
Tags & instant search
Tag cards by topic and find anything by its front, back or tags as you type.
Your data, stored plainly
Cards are saved as the exact Markdown you wrote, never converted or locked into a format.
Dynamic cards
Cards that get harder as you get better
A flashcard usually asks the same thing forever. A dynamic card hides part of its answer and shows you the rest as a hint. As you improve, the hints fade until you recall the whole answer on your own.
- 1No extra workEvery list item on the answer side is a part. For anything else, wrap it in {{double braces}}.
- 2It adaptsA new card starts by hiding one part. Recall it and Rcll hides more; miss something and it eases off.
- 3Tap what you missedInstead of grading yourself, mark the parts you got wrong. Rcll rates the card for you and hides your weak spots more often.
Recall the blanks first.
Live demo
Write a card. Watch it render.
This is the same renderer the app uses. Edit either side and flip the card to check your answer.
Try an example:
Markdown, tables, code and $math$. Every line break and blank line shows up exactly as you type it. List items and {{gaps}} on the back become parts of a dynamic card.
Click the card or press Space to flip
How it works
Three simple steps
- 1
Write
Create cards in Markdown, or let AI draft them from a PDF. The preview shows exactly how they will look.
- 2
Collect
Group cards into routines by tag or search. New cards that match are added automatically.
- 3
Study
Rcll schedules your reviews and hides more of each answer as you get better at it.
Roadmap
What's next
Import & export
Bring cards in from CSV or other flashcard apps and take your data with you any time.
Planned
Offline studying
Keep reviewing without a connection and sync your answers once you're back online.

Questions
Is Rcll free?
PLACEHOLDER: describe pricing here once it is decided.
Why is there no lifetime plan?
Because the AI features cost money every time you use them. Each set of cards drafted from a PDF and each answer checked runs a large AI model that we pay for per use, month after month, for as long as you study. A one-time price works for software that costs nothing once it is sold, but ours keeps costing as long as you use it. A lifetime plan would have to be priced very high, or the AI features would have to get worse for lifetime users over the years. A subscription keeps the price fair and the AI features as good as they are today.
What are dynamic cards?
Cards whose answer has parts: list items, or anything you wrap in {{double braces}}. While you study, Rcll hides some of the parts and you recall them. It starts with one and hides more as you improve. After revealing, you tap what you missed and Rcll rates the card from that.
Does Rcll schedule my reviews?
Yes. Spaced routines use FSRS to show each card right before you would forget it. Every routine keeps its own schedule, and you choose the target retention. Shuffle routines go through every card once in a fresh order instead.
Is there a mobile app?
Rcll runs in the browser and can be installed to your home screen: on iPhone, open app.rcll.pro in Safari and choose Share, then Add to Home Screen. Study sessions are made for touch, with swipe to answer. Native apps are on the roadmap as an idea we are exploring.
How does Rcll use AI?
Only for things you ask for: drafting cards from a PDF, suggesting tags for a card, and, in routines with active recall turned on, writing short exercises and checking your answers. Drafts are never saved until you review and keep them.
Which Markdown features are supported?
GitHub-flavoured Markdown: bold, italics, lists, tables, links and fenced code blocks, plus LaTeX math with $…$ and $$…$$. Line breaks and blank lines appear exactly as you type them.
Which languages does the app support?
English and German. Your cards can be in any language.
Can I import cards from other apps?
Import and export are planned. See the roadmap for what is coming next.
