What does the free plan include?

Free is free for everyone, always, with no card. You get all 12 areas and every topic in the standard version, plus one new area's AI version each day (there's no lifetime cap). You also get the standard whole-life synthesis, the goal tracker, weekly reviews, monthly check-ins, your library, printing and exporting, and one re-take after 90 days. If you've already used today's AI area, the page says "tomorrow: next area".
