Concepts you can scrub & feel.

Skip the 40-page docs. Every explainer turns a tricky AI, Claude Code, MCP, or cloud idea into a live, animated diagram you can drag, scrub, and break — so the concept finally clicks in minutes, not hours.

How it works

Three steps. The idea sticks.

01

Read the 60-second analogy

Every concept opens with a short, plain-language story. No jargon, no fluff — just the mental model you need.

02

Scrub the live animation

Press play, drag the timeline, or tap the arrow keys. Watch each step fire frame-by-frame until the flow makes sense.

03

Push the sliders to the edge

Tweak every parameter. The diagram updates instantly so you feel the trade-offs and remember the limits.

AI Coding Assistants Compared: Cursor vs Copilot vs Claude Code

Three philosophies — Copilot completes, Cursor edits, Claude Code drives. Pick by how much agency you want the AI to have.

GitHub Copilot vs Claude Code: Inline vs Agentic

Copilot speeds up typing. Claude Code finishes tasks. Different jobs, different tools — and increasingly, the same engineer uses both.

AI Code Review: How LLMs Catch Bugs Humans Miss

AI code review is a tireless first-pass reviewer. It misses architectural nuance but rarely misses an off-by-one. Use it as the floor, not the ceiling.

Agentic Coding: From Autocomplete to Autonomous Engineer

Agentic coding is when the AI plans, edits, runs tests, and iterates — without holding your hand at every step. The unit of work shifts from "line" to "task."

Cursor: The AI-Native Code Editor Pattern

Cursor takes VS Code and rebuilds the editor around AI — multi-file edits, tab-to-accept, repo-aware chat. The "editor as AI surface" approach.

Spec-Driven Development With AI Coding Agents

When the AI is the implementer, the spec is the lever. Tight specs ship fast and clean; vague specs ship vague code. Treat the spec like the new keyboard.

Function Calling: How LLMs Use Your APIs

You describe a function in JSON Schema; the model decides when to call it and produces typed arguments. The bridge from "pretty text" to "real action."

Structured Outputs and JSON Mode: Reliable LLM Responses

Stop parsing prose. Constrain the model's output to a schema and your downstream code stops guessing. The single biggest reliability lever in LLM apps.

LLM Streaming: Why First-Token Latency Beats Total Time

Streaming sends tokens as the model produces them. Total wall-time is similar; perceived speed is dramatically better — and lets you cut off when the answer is good enough.

API Rate Limits, RPM, and TPM Explained

Two budgets you cannot ignore: requests per minute and tokens per minute. Understanding both — and the burst behaviour around them — keeps your prod stable.

LangChain vs LlamaIndex: When to Pick Which

LangChain is the kitchen-sink agent framework. LlamaIndex is the RAG-focused data framework. Same neighbourhood, different specialities.

OpenAI SDK vs Anthropic SDK: API Patterns Compared

Same family of APIs, different shapes. Knowing the differences saves an afternoon of head-scratching when porting code between providers.
