Understand the real difference between Claude Chat and Claude Code — and decide which one is right for your work.
Claude Code and Claude Chat both use the same underlying AI model. The difference is what they can do.
| Claude Chat | Claude Code | |
|---|---|---|
| Where | claude.ai in your browser | Terminal, VS Code, or desktop app |
| Can edit files on your computer | No | Yes |
| Can run commands | No | Yes |
| Can commit to GitHub | No | Yes |
| Can automate tasks | No | Yes |
| Remembers your project | Only with Projects (Pro) | Yes — reads CLAUDE.md always |
| Supports skills / slash commands | No | Yes |
| Supports hooks (auto-actions) | No | Yes |
| Can use MCP servers | Limited | Full support |
| Needs installation | No | Yes (5 min) |
| Good for writing, research, ideas | Yes | Yes |
| Good for building and automating | No | Yes |
Before you install anything, know which version you need:
| Web App | Desktop App | VS Code Extension | Terminal CLI | |
|---|---|---|---|---|
| Install needed | No | Yes (.dmg / .exe) | Yes (VS Code ext) | Yes (install script) |
| Reads your local files | No (cloud only) | Yes | Yes | Yes |
| Runs commands on your machine | No | Yes | Yes | Yes |
| Skills, hooks, MCP | Partial | Yes | Partial | Yes (full) |
| Works on mobile | Yes (iOS app) | No | No | No |
| Checkpoints / undo | No | No | Yes (inline) | No |
| Best for | Remote, no install | Visual, non-developer | VS Code users | Power users / scripts |
Our recommendation: Start with the Desktop App if you want the simplest experience. If you already use VS Code, install the extension instead. Switch to the CLI when you want full automation power.
Use Claude Chat when you want to think and write.

Use Claude Code when you want to build and automate.
- Edit files on your computer
- Build scripts that do things automatically
- Manage code and git repositories
- Create automations that run while you sleep

You'll get real value from Claude Code if any of these are true:
You don't need to be a developer. Claude Code is designed to help people who aren't programmers build things that work.
That's completely fine. Modules 1 and 2 alone will dramatically improve your AI output. Come back to Module 3 when you're ready to go further.
Here's what changes when you switch to Claude Code:
CLAUDE.md — A file you write once that Claude reads automatically. Your clients, your preferences, your rules. Loaded every session. No pasting.
Skills — Slash commands you invoke in one line. /insync-social Write a post about X — done.
Hooks — Automatic actions that happen without you asking. Format a file every time Claude edits it. Run a test every time code changes. Notify you when Claude finishes.
MCP servers — Connect Claude to Notion, Slack, GitHub, databases. Claude can read your Notion tasks, post to Slack, create GitHub issues — all from one conversation.
Subagents — Spawn specialized AI assistants for research, code review, security — each with their own focus, running in parallel.
