Where should I start?

Instead of describing what you want, show the AI two or three examples. Few-shot prompting is often the fastest way to get consistent output.
Bad output is almost never random. It's a clue. Here's how to diagnose and fix a broken prompt instead of just mashing the regenerate button.
AI-assisted coding is not magic and not cheating. It is a new way of working where a model drafts, you decide. Let's draw a map before we start building.
Time to get hands on. Install a real AI coding editor, sign in, and write your first line together. No credit card required to start.
Let's make something real. A single-page site with HTML, CSS, and a little interactivity. You plan, the AI drafts, you review and ship.
Bring it all together. Pick one of three starter projects, plan it, build it with AI, and deploy it. You are now a builder who ships.
Claude.ai and the Anthropic API both run Claude. So why do they cost different amounts? Pull apart the two doors into the same model.
Artifacts is Claude's canvas. Charts, code, docs, and interactive React components render live next to the chat.
Deep Research is Gemini's multi-step research agent. You ask a question; it plans, searches, reads, synthesizes, and delivers a report.
v0 by Vercel turns a prompt, screenshot, or Figma file into a working Next.js app deployed in one click.
Upload a PDF, a set of docs, or a research paper. NotebookLM produces a two-host podcast conversation about the material.
A Space is a bookmarked, collaborative research context. Your sources, your prompts, your team — all persistent.
Midjourney is the artist favorite. FLUX.2 Pro is the API-native challenger. Here is which one to pick depending on what you are making.
GitHub Copilot was the first AI coding assistant at scale. Look at what it is great at, where Cursor and Claude Code have passed it, and whether the $10 subscription still makes sense.
v0 by Vercel generates working React and Next.js code from prompts. Look at what it nails, what it still gets wrong, and why it's changed how startup MVPs get built.
Reading and writing files is where real scripts start. Learn the with-statement, path handling, and JSON round-trips.
Stable Diffusion, Midjourney, and DALL-E all trace back to LAION, an open dataset of 5 billion image-text pairs. It changed AI, and started a legal storm.
