📈 Anki Invest: turn your reviews into a stock portfolio and donate to charity

Study in Anki, and give to charity for real. Your reviews earn play money. Give it to St. Jude Children's Research Hospital, Doctors Without Borders or Feeding America on ankitrade.org, and the site's owner donates the real dollars it becomes. Free, no ads, and you never pay a cent.

How giving works

• $5,000,000 of play money becomes $1 that the site's owner donates. Gifts start at $500,000 (10¢) and go in steps of a cent.
• You pick the charity: St. Jude Children's Research Hospital, Doctors Without Borders or Feeding America.
• Each month's totals are donated after the month ends, and the Donate page lists what was sent.
• Real studying only: accounts at least a week old with 500 reviews can give, and every gift is checked for farmed reviews before it counts.

How studying pays

• $100 a review of an average card, from $60 to $200 by how hard the card is.
• $5,000 for the daily goal: 50 reviews, or every card due today done (at least 10).
• $3,000 more for finishing every card due today.
• Streaks: $500 more on the daily goal for each day of your streak after the first, up to $10,000.

Grow it first, if you like. On ankitrade.org your play money also buys stocks, ETFs and crypto at live market prices, and calls and puts from real option chains. Climb the leaderboards, take ten short lessons that pay $2,500 each ($25,000 for all ten), and read a weekly check-up on your portfolio written by Claude. The more it grows, the more you can give.

It all lives in Anki. Click Invest in Anki's toolbar for a panel with your portfolio and your stocks at live prices; click again to hide it. Every page of the site, Donate included, opens in its own Anki window, already signed in. A box under your deck list shows your portfolio live too: the total, its line, buying power, what you've invested and your reviews today (make it one line or hide it with its own buttons).

Setup: install, restart Anki, then Anki Invest → Account… and sign in with your AnkiWeb email and password (checked with AnkiWeb once, never stored), or make an account with one click. Reviews you've already done today count right away.

Only real studying counts. Answers faster than 0.8 seconds, more than 3 answers to one card in a day, and trivial or look-alike generated notes don't earn; a day can't pay for more reviews than its study time allows. Reviews done on your phone count once desktop Anki has them, as long as they're from today or the two days before.

Play money only. It can't be bought, sold or withdrawn. Giving it to charity is the one way it becomes real money, and the site's owner pays for that. Nothing on the site is financial advice.

Privacy: the add-on sends your review counts for each day (how many, how long they took, how hard the cards were), how many cards are still due, and your time zone. Since 1.5.0 it also sends a short summary of each day's answers, so farmed reviews can be caught: how long they took, the cards' intervals, which buttons you pressed, how much is written on the cards, and the text of the few cards you answered most that day, shortened. Only the site's owner sees that summary; it never changes what you earn, and it's deleted after 90 days. You can delete your account and everything in it from the site's Account page.
