Every play, in full: the observations, the evidence and what it does not establish, and the sources. The Duolingo playbook stays free too. You can read it all without an account, and copy five records a month into your agent in one click. Copying the same record again that month is free; reading never counts.

Every curated playbook after Duolingo — each groups plays into a path for one kind of product — and the Motifs MCP, so your coding agent can pull a record itself instead of you pasting it. Both are in development: founding members get each one as it ships, along with every later collection.

Sign in with the email you paid with. We email you a link — there is no password to set — and your playbooks and unlimited copying are there when you land. On a new device, do the same.

The library is young. The first 100 members pay $30 once or $4.99 a month and keep that price, in exchange for backing it early. After the first 100 the price goes up.

Yes, whenever you like. Everything free stays free, and the founding price is held for as long as you stay subscribed.
