Inside AI is an interactive field guide to how AI agents and large language models actually work, built for the curious skeptic. Learn from the source, not the hype. No accounts. No ads. No tracking. No internet required. Everything runs on your device. START HERE Where does AI actually live? See the data center, the many copies of a model, and how agents and tools really fit around it. WATCH AGENTS WORK See a live two-agent Writer ↔ Reviewer loop pass work back and forth until it's approved — a feedback loop you can actually watch, step by step. UNDERSTAND THE AGENT'S TOOLKIT Tool-calling, ReAct, RAG, MCP, multi-agent pipelines, A2A, computer use, prompt injection and reliability — the patterns behind every modern AI agent, each shown as a hands-on demo you can poke at. SEE INSIDE THE MODEL Tokens and the context window. Next-token prediction, one piece at a time. Attention weights across a sentence. Parameters and training with real gradient descent. Quantization, and which small models fit on your own device. Watch the ideas behind every LLM come to life. MEANING, LIMITS & CONTROL Embeddings and cosine similarity. Vector databases. Hallucination — and how grounding fixes it. Bias. Structured output. WORK WITH MODELS Prompts and chain-of-thought. Reasoning models with a thinking budget. What the model actually receives on each turn, and what it keeps when a long chat overflows. Evaluation, benchmarks, and how leaderboards get gamed. BUILD A SECOND BRAIN Turn a folder of linked markdown notes into an AI-queryable knowledge base — that's RAG, pointed at your own notes. Explore the bundled vault of 42 linked concept notes. REAL OR MOCK — ALWAYS LABELED Every demo carries a REAL or MOCK badge. REAL means genuine logic is running on your device. MOCK means it's a scripted illustration. You always know exactly what's running — no smoke, no mirrors. Most demos are scripted, and every one says so with a MOCK badge. That's why you can trust the ones marked REAL. RUNS ANYWHERE Works on any iPhone or iPad running iOS 17 or later. The demos use scripted mock agents, so no Apple Intelligence and no special hardware is required. Whether you're a developer, a student, or just AI-curious, Inside AI replaces buzzwords with understanding — one interactive concept at a time. Free to use. If it helps you, there's an optional tip jar — but nothing is ever gated.
