Due Crew -- study with friends!

Your friends' studying next to yours, on Anki's Decks screen.

Studying for a big exam is more fun with friends! Due Crew puts your crew on Anki's Decks screen: who's studied today, who's studying now, how far each of you has gotten. Above them is your own day: what's due, what your plans open, your to-dos. You only see people you've added, and they see you once they add you back. Your cards never leave your computer.

Your crew

Cheers. Point at a friend's name, tap 🎉 Cheer, and a little show lands on their Decks screen, a different one each time, with your note. Or draw them something: your Pip holds it up, and it stays pinned beside their board.

Study rooms. 25-minute rounds with your crew, the timer in Anki's top bar, breaks together. Each of you sits in the room as your own Pip, in your own colour. Rain, a fire, waves or brown noise if you like.

• Stuck on a card? Ask your crew. Anyone who has it down can send a tip, which shows next time the card comes up.
• Good-luck cards. Leave a line the night before a friend's exam.
• Profiles. Half a year of a friend's studying, and your days in a row together.
• Shared decks. The decks you have in common, side by side.
• Status, exam and away dates, just-show-up mode, six accent colours, and your board and log on duecrew.com.

Squads and bingo

A squad is a group with a code: a class, a study group, the people in your year. Every Monday it gets a new 3×3 card of studying squares: an early start, twenty minutes without a break, a day with nothing left due, new cards three days in a row. Most need more than one of you, and the middle unlocks when enough of you do something together. Three in a row is bingo. Under the squad, the week adds up: "23 study days between 5 of you".

Your day

Above the board is yours.

• Today is what's due, what your plans open, ticking itself as you review, and your own to-dos. Type "every mon" and one comes back each week.
• Upcoming is the next two weeks, and Later whatever has no day yet.
• QBank QIDs: after a practice block, paste the IDs of the questions you missed. Unsuspend their cards, or study them now.
• Fifteen? One click in Anki's top bar starts fifteen minutes of study, your plans' decks first. At the end: take five, go again, or stop there. Your crew sees you're studying. Not started by your usual time? Today nudges you.
• Insights, for any deck: your reviews for the next six weeks, counted from your own reviews, and what stopping new cards before your exam would do (one click to stop, one to start again); the cards Anki won't show you before your exam; the leeches Anki stopped showing you, one button each to bring them back; what isn't sticking yet; and a map of what you know, by topic or by the week you started it. It's worked out in your Anki and never sent; copy the map as a picture or as text if you want to share it.
• Your year. From 1 December, your year in Anki as a short story, made on your computer from your own reviews. Tools → Due Crew → Your year… has any year Anki remembers.

Pip, the square from the logo, keeps you company: heads down in a fifteen, breathing with you on a break, a hop when the day's done, a wave when you're back. It keeps still with Reduce motion on, and Settings turns it off.

Study plans

Plan a class's or a crew's studying, in Anki (Tools → Due Crew → Plans → New plan…) or on a calendar at duecrew.com: pick chapters from a deck, set a pace, mark the exam, and share the code. Everyone following gets that day's cards each morning. Behind? Catch up or Push my dates back.

• Your week. You › Plans shows the plan's seven days; click one for its assignments. Following two plans? Switch between them by name.
• Your plans… in Anki: the plan's weeks and dates beside your deck, Insights (the workload week by week, how much of the deck it covers), and its settings. An author's changes wait under the plan until sent.
• Each morning, in Anki. Cards open in Anki on your computer, after its sync; sync again and your phone has them. Studying on your phone first? Your plans… › Settings › More › Open early.
• Hold back. A deck with every card showing? Follow holds the later dates back until their day.
• Study a date, or a quiz. Each date has Study: its cards in one deck, a cram before class. Three days before a quiz, Study for it puts every date that preps for it in one deck, the shakiest first.
• Your own pace. Follow a plan with its cards opening When I'm ready: Up next opens the next date, first in Anki's line of new cards, or opens it by itself once you've seen most of the last one. Your pace and when it gets you to the end show underneath.
• Draft it with your own AI. Tools → Due Crew → Plans → Export cards for my AI, then the plan's AI prompt (Plan the dates, or Tag by objective) (the format). Your cards stay on your computer.
• Plan tags. A plan can put its own tags on your notes (DueCrew::Block_1::Lecture_12), so a lecture's cards are one click away in Browse. Its authors make them in Anki or on duecrew.com.
• A plan's squad. See who showed up today, ask and answer questions, and play bingo with everyone on the plan.
• Plans can have co-authors (each says yes first), notes for followers on a video or a card, go in your calendar app, and be shared in the library.

In Anki's browser

Right-click a card, or a tag in the sidebar:

• Why isn't it showing? Suspended, buried, past today's new-card limit, not due till Friday: each in Anki's own words, with Anki's own fix, one Undo away.
• Open its cards / open these. Unsuspends a tag's cards, or the ones you picked, first in line for new cards. Leeches stay suspended.
• Show on my plan finds the date a card belongs to, and Tag for a plan is for a plan's authors.

Share

Share your day, week, year or all time as a picture, made in Anki. Pip hops across your week. Pick which numbers show, then copy or save it. It goes only where you paste it.

Install

Tools → Add-ons → Get Add-ons, code 2035408484. Needs Anki 2.1.55 or newer. Restart Anki after installing.

Get started

1. Click Start with your email on the Decks screen and type in the code we send you. No password.
2. Paste an invite, or a class, squad or plan code, on the welcome screen. Or copy your invite and send it to a friend.
3. Someone added you? Click Add back.

Privacy

Your stats go only to people you've added and squads you join. Choose what you share in Settings → Privacy, or pause at any time. Anyone else sees your name and emoji, nothing more. Card text never leaves your computer: a crewmate sees a card's text only if they have the same card, and a plan holds card and note IDs, which each follower's Anki looks up in its own copy. Insights, your topic map, your year and your progress on each bingo square stay on your computer. Your email is used to sign you in. Your own to-dos are kept with your settings, so every computer has them; only you see them. If you write in, Sam, who runs Due Crew, can look up your account, your squads and who's on your crew list to fix problems; never how you study, and each look is logged. Feedback you send goes to Sam with your name. Deleting your account deletes your data. Accounts with no activity for 12 months (24 when paused) are deleted with everything in them; opening Anki with Due Crew on, or signing in at duecrew.com, counts. The add-on and server are on GitHub.
