Start free. Upgrade when you're ready.
These plans are for Step 2 CK only. Step 1 is still in beta and stays free, so there is nothing to buy for Step 1.

Plans renew automatically at the same price until you cancel. Cancel any time from "Manage plan" and you keep your plan until the end of the period you paid for. By subscribing you ask for access straight away, so the 14-day right to withdraw no longer applies once your plan starts. Secure checkout by our reseller and merchant of record. Prices in USD; tax may be added at checkout. Refunds within 14 days, see our Refund Policy.
Questions
Can I cancel?
Yes, any time. Sign in, open this page and click "Manage plan", then choose Cancel subscription. You can also use the link in any receipt email, or email us and we will cancel it for you. You keep your plan until the end of the period you paid for, and you are not charged again.
What happens when I use my 60 Basic look-ups?
Everything else keeps working: flashcards, the QBank and the Concept Library have no limit. Your 60 look-ups come back every month on the day you subscribed (subscribe on the 25th and they refill on the 25th), or you can switch to Pro for 60 a day.
Can I switch between Basic and Pro?
Yes, any time, from "Manage plan" once you are signed in. The price is adjusted for the rest of your period.
I was a beta tester. Do I have to pay now?
Not straight away. As a thank you, Step 2 beta users get Pro free until November 7, 2026. You'll see your plan and its end date on this page. When it ends you move to the Free plan; you are never charged unless you subscribe yourself.
What about Step 1?
Step 1 is still in beta and free. These plans add nothing to Step 1, so please do not subscribe for it. Nothing on Step 1 is locked. New Step 1 sign-ups go to a waiting list for now.
Who handles the payment?
Paddle.com, our reseller and merchant of record, so your receipt and card statement will show Paddle. Subscriptions started before November 5, 2026 stay with Lemon Squeezy until they end. Either way, the reseller handles your card details and any sales tax or VAT; we never see your card number.
Do the plans work in the Anki add-on?
Yes. Sign in to the add-on with the same account and your plan applies there too. Look-ups in the add-on and on the website share the same allowance. Related concepts have their own: Free can try them on 3 cards, Basic gets 60 cards a month and Pro has no limit, so they never use up a look-up.
