CwikCard turns a question CSV into flashcards and schedules them with spaced repetition, the way Anki does: each time you see a card you rate how well you remembered it, and that rating decides when you see it next.

Getting started

1. Get a question CSV. The easiest way is QuizQrusher's AI workflow, which writes one from your lecture slides. Its header row is Category, Question_Text, Option_1 … Option_6, Correct_Option_Number. Download an example CSV
2. On Decks, choose Add a deck and drop the CSV in. Or press Try a sample deck to look around first.
3. Press Study. Read the front, recall the answer, press Show answer (or Space), then rate yourself: Again, Hard, Good or Easy.
4. Come back each day. The deck list shows what's waiting: newlearningto review.

Making cards

Every row of the CSV becomes one note. Its question goes on the front, its correct option on the back, and its category becomes the card's tag. The other options are kept too: Settings > Studying can show all the answer choices on the front (multiple-choice style) or list them on the back.

• Direction: each deck can show Front → Back (question first), Back → Front (answer first: recall the question it belongs to), or Both, which makes two cards per note that are scheduled separately. Change it in the deck's options.
• Updating a deck: if you get a new version of the CSV, open the deck and use Update from CSV. Cards whose category, question and correct option didn't change keep their progress.
• Editing: press E while studying, or Edit in Browse, to fix a card's wording. Edits stay with the deck and the card keeps its progress.

Studying

Rating	Use it when	What happens
Again 1	You forgot or got it wrong	The card comes back in this session, and its next interval shrinks.
Hard 2	You got it, with real effort	A shorter step than Good.
Good 3	You got it after a moment's thought	The normal next step. Use this most of the time.
Easy 4	It was instant	A bigger jump, so you see the card less often.

The small times under the buttons show when you'll see the card again for each choice. New cards first go through short learning steps (by default 1 and 10 minutes) before they graduate to days. A forgotten review card goes through relearning steps the same way.

Each deck shows at most 20 new cards a day by default, so a big deck is spread over days instead of buried in one sitting. Change the limits in the deck's options, or press Learn more new cards when you finish. The day rolls over at 4 AM (Settings > Studying), so a late-night session still counts as today.

Scheduling

Pick a scheduler for each deck in its options. You can switch at any time; cards keep their due dates.

• FSRS (recommended): the Free Spaced Repetition Scheduler that Anki uses today. It tracks how stable each memory is and how hard the card is for you, and schedules the next review for when you're likely to still remember it at your desired retention (90% by default; higher means more frequent reviews). CwikCard uses FSRS-5 with its standard parameters.
• SM-2 (classic Anki): each card has an ease (250% to start). Good multiplies the interval by the ease, Hard by 1.2 and lowers the ease, Easy adds a bonus and raises it, and Again lowers it and starts relearning. The graduating interval, easy interval, ease, bonuses and interval modifier are all in the deck's advanced options.
• Leitner boxes: the paper-flashcard method. Cards move up a box when you get them right (Easy skips a box) and back to box 1 when you miss them. Box 1 is reviewed every day; the default boxes are 1, 2, 4, 8, 16 and 32 days apart.

Like Anki, intervals of a few days or more get a little random fuzz so cards learned together don't all come due on the same day. A card you keep forgetting (8 lapses by default) is a leech: it's tagged so you can find it in Browse, or suspended if you set the deck to do that.

Practice rounds

Practice round runs through cards without touching their schedule, for cramming before an exam or drilling a weak category. Choose which cards (all, flagged, ones you've struggled with, never studied, or missed today), which categories, the direction (or mixed), and how many. Cards are shuffled with the same shuffle engine QuizQrusher uses for questions, which never repeats the previous order. With Repeat missed cards on, a card you miss comes back a few cards later until you get it.

Keyboard and touch

Key	Action
Space or Enter	Show the answer; once it's shown, rate Good (Got it in a practice round)
1 2 3 4	Again, Hard, Good, Easy (in a practice round: 1 Missed it, 3 Got it)
Z or Ctrl+Z	Undo the last answer, bury or suspend
F or *	Flag or unflag the card
B	Bury: hide the card until tomorrow
S or @	Suspend: hide the card until you unsuspend it in Browse
E	Edit the card
+ and -	Bigger or smaller card text
Esc	End the session
?	Show the shortcuts
/	In Browse, jump to the search box

On a phone or tablet, tap the card to show the answer, then swipe it right for Good or left for Again (Got it or Missed it in a practice round), or use the buttons. Swipes can be turned off in Settings.

Managing cards

• Flag marks a card to come back to; practice rounds and Browse can show just the flagged ones.
• Bury hides a card until tomorrow. Suspend hides it until you unsuspend it in Browse; use it for cards you already know cold or don't need.
• Browse lists every card with its state and due date. Search it, filter it (new, learning, due today, flagged, suspended, buried, leeches), and flag, suspend, edit or reset cards from there. Reset makes a card new again.
• When Both directions are on, a note's two cards aren't shown in the same session, so one doesn't give away the other.

Saving and backups

• Every answer saves in this browser right away. Nothing is uploaded.
• Export deck (in a deck's tools) downloads one deck with its progress as a .json file; Settings > Data > Export all saves every deck and your settings. Bring either back with Add a deck. Use them to move to another device or browser.
• Safari can delete a site's data after about seven days without a visit, and private windows keep nothing, so export now and then.

Install it as an app

On the hosted site, CwikCard can be installed like an app and then opens without an internet connection. In Chrome or Edge, use the install icon at the right end of the address bar. On an iPhone or iPad, in Safari, tap Share, then Add to Home Screen. When a new version is out you'll see "A new version of CwikCard is ready": press Reload.

The down arrow next to the CwikCard name opens a menu of the other study apps: QuizQrusher for practice quizzes, and InfoBase for searching your slides and textbooks. Home, at the bottom, goes to the study apps homepage.

Settings

The ⚙ in the top right corner. Appearance (theme, accent color, color-blind-safe colors, reduced motion), text (size, line spacing, an easy-to-read font, card text size), studying (category tags, answer choices, next-review times on the buttons, keyboard hints, swipes, the timer, when the day rolls over), defaults for new decks, and data tools (storage use, Export all, Clear all). Each deck's own options (scheduler, direction, daily limits, steps) are on the deck's page.

Privacy

• Your decks, progress and settings stay in this browser. Nothing is uploaded.
• The app loads nothing from other sites; its fonts and icons are built in. It doesn't collect usage statistics.
• Found a bug or have an idea? Use the feedback form (Google Forms, opens in a new tab).
