Start learning. No account needed.
One plan, paid monthly or yearly. Only Pro takes a card, and its 7-day trial charges nothing until it ends.
Free for 7 days, then $9 a month. Cancel before then and you pay nothing.
A session is one topic explored across six stages. The two guest sessions are a one-time allowance; free sessions and code reviews reset each calendar month. Reading articles and exploring Studio figures never uses a session.
Frequently asked
What counts as a session?
A session is one topic worked through in six stages, started from your workspace. Continuing or reloading a session you already started does not use another one.
What does Pro add?
Unlimited study sessions and unlimited Practice code reviews. Everything else is free already: the Library, and every Studio figure with its SVG and PNG exports.
Should I pay monthly or yearly?
It is the same plan either way. Monthly is $9 a month. Yearly is $72, which works out at $6 a month. You can switch from Profile, under Manage billing, and Stripe shows any prorated amount before you confirm.
How does the free trial work?
First-time subscribers get 7 days free on either billing period. You enter a card at checkout and are not charged until the trial ends. Cancel before then and you pay nothing.
Can I cancel anytime?
Yes. Open Profile and choose Manage billing to cancel with Stripe, update your payment method, or download invoices. You keep Pro until the end of your trial or billing period. If you need help, email liminalmlprep@gmail.com.
What stays free in Studio?
All of it. Every figure, in either theme, with SVG and PNG export. You do not need an account.
Do you offer a student discount?
If you have a promotion code, enter it on the Stripe checkout page. Students and open-source contributors can email liminalmlprep@gmail.com.
What happens to my work if I stop paying?
Nothing is deleted. Your profile and sessions stay, and the free allowances apply again: 8 sessions and 5 Practice code reviews per calendar month.
Which payment methods can I use?
All major credit and debit cards, plus Apple Pay, Google Pay and Link, through Stripe Checkout. Stripe never shares your card details with us.
Which model powers LiminalML? Can it be wrong?
LiminalML is built on Claude through the Anthropic API. Like any language model it can be confidently wrong, so every derivation step is shown for you to check, and anything important should be verified against a primary source.
Is my data private?
Study stores account data in Supabase with access limited to your user ID. Relevant profile context, messages, answers and code are sent to Anthropic to generate feedback. We do not train models on your content. You can delete sessions in the app, or contact support for an account export or deletion. The Privacy page lists every processor.
