Common questions

What counts as a daily insight credit?

Each new concept, framework, or abstract you explore in the graph uses one credit. Re-visiting previously explored nodes is always free.

Can I cancel anytime?

Yes. Subscriptions are month-to-month with no commitment. Cancel in one click from your account page.

What makes this different from book summaries?

Summary services tell you what a book says. Margin Notes shows you how ideas connect across books — with 17 typed relationships, cross-book analysis, and 938 individually written analytical posts.

How many books are in the graph?

Currently 14 deeply processed books with 300+ queued for ingestion. The graph grows every week, and every new book enriches every existing connection.
