EVERY LESSON INCLUDES • A working thesis the author defends, not just summary • 4–6 chapters of structured argument with a clear ramp • Predictions before answers — calibrate your gut before the lesson tells you • Real cases with named companies, real numbers, and honest "this is composite" notes where it isn't verifiable • Five interactive moves: quizzes, drag-drop matches, group-chat dialogs, message-flow walkthroughs, case studies • A metaphor per chapter that makes the idea stick WHAT MAKES LIMNI DIFFERENT • Lifetime ownership — buy once, keep forever. No subscription tax. • Honest voice — the author argues a position, then defends it. You'll know if you agree or disagree. • Fixed cases over generated examples — when a case is composite, we say so. • On-device, private — no accounts, no email, no tracking, no servers. Your reading progress lives only on your phone. • Free first lesson — sample lesson 1 of any course before you decide to unlock the rest. WHO IT'S FOR • PMs and technical builders who want a working frame on a project worth understanding • Curious adults who want to actually learn AI craft, not just "stay current" • Indie taste — readers who buy at $0.99–$1.99 because they appreciate the craft WHO IT'S NOT FOR • Anyone wanting auto-generated content or AI-generated "courses" • Subscribers — Limni is pay-once • People who want certifications, badges, or homework checks NEW COURSES SHIP EVERY FEW WEEKS The developer ships courses on their own schedule.
