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. Restore Purchases brings everything you bought back to any device signed into the same Apple ID.

Prepare for Anthropic's Claude Certified Architect – Foundations (CCA-F) exam with a study companion built around how the exam actually tests you: scenario-based questions about real architectural decisions. EVERY DOMAIN, EVERY TOPIC Browse all five CCA-F domains — Agentic Architecture & Orchestration, Tool Design & MCP Integration, Claude Code Configuration & Workflows, Prompt Engineering & Structured Output, and Context Management & Reliability — with concise topic summaries and curated links to official documentation, Anthropic Academy courses, and conference talks. ORIGINAL ARCHITECTURE DIAGRAMS Per-topic diagrams show how Claude, the Agent SDK, Claude Code, and MCP servers fit together — agent loops, tool-use flows, context windows, multi-agent orchestration. Zoomable and fully offline. ADAPTIVE PRACTICE QUIZ Hundreds of original, scenario-style practice questions modeled on the exam format (never real exam content). The quiz adapts: domains you miss show up more often, domains you ace fade back. Every question explains why the right answer is right — and why the tempting one is wrong — with a citation into the official docs. KNOW WHERE YOU STAND Daily and weekly progress stats plus a per-domain strength radar mapped to the official exam weightings. One tap starts a focused quiz on your weakest domain. AI TUTOR, GROUNDED IN THE DOCS Stuck on a concept? Ask the built-in AI tutor (Claude, via Amazon Bedrock). Answers are grounded in official Claude, Claude Code, and MCP documentation and cite their sources. The tutor stays on topic and will not provide real exam questions or answers. OFFLINE-FIRST, PRIVACY-FIRST All study content works offline — only the AI tutor needs a connection. No account, no sign-up, no ads, no tracking. The first domain and 10-question practice quizzes are free; a one-time Premium Unlock opens all five domains, the full question bank, longer quiz modes, and unlimited AI tutor use. Content is refreshed weekly against the latest official documentation. This app is not affiliated with, endorsed by, or sponsored by Anthropic, PBC.
