Most people use one mode of Claude. There are three. Here's what each one actually does.
Chat, Co-work, or Code:
Which mode does what
Three modes. One is a food court. One is your kitchen. One is your whole restaurant. By the end of this guide you'll know exactly which one to use and when.

Insight 01
Three Modes. One Cooking Show. One Kitchen. One Restaurant.
Most people only watch the cooking show. That's where 90% of Claude's power stays untouched.
Most people only watch the cooking show. They ask Claude questions and copy answers into their own tools. That's 10% of what Claude does.
Cooking Show
Chat
You watch the chef on TV. They walk you through every step. You head to your own kitchen to cook it yourself.
The chef talks. You do the work. Great for questions, research, and brainstorming.
Your Kitchen
Co-work
The chef comes to your kitchen. Opens your fridge, cooks, plates it up. You watch.
Claude does the task. Inside a safe sandbox. Great for documents, scheduled work, connectors.
The Restaurant
Code
You hand over the keys. They run the whole place. Multiple kitchens. Multiple chefs.
Full access, multi-agent workflows, persistent memory. Great for complex systems and projects.
Hover a panel to go deeper. Each mode has its own job.
Insight 02
Chat: The Cooking Show
Fast answers, cross-session memory, works with what you upload. Great for thinking. Limited for shipping.
Quick questions with clear answers
Ask anything. Get a concise answer. No setup, no files touched.
Brainstorming and thinking aloud
Use it as a thinking partner. Push an idea around until the shape is right.
Research and summaries
Pull together context on a topic. Ask follow-up questions without losing the thread.
Getting advice before you decide
Pressure-test a plan before you commit time and money to it.
Superpower
Remembers every conversation you've ever had
Your name, your role, your clients, your preferences. Walk back in six months and it already knows you.
Risk
Cross-chat memory can leak across clients
Information from Client A could quietly influence responses about Client B. Use Code or Co-work for anything sensitive.
Insight 03
Co-work: The Chef In Your Kitchen
Claude does the task inside a safe sandbox. Connect your apps and step away.
How a Co-work session flows
You ask
"Draft my weekly client report from these 4 calls."
Claude plans
Opens connectors, pulls transcripts, drafts the report.
You review
Pop in, give feedback, pop out. Claude finishes.
Delivered
Doc saved to Drive, shareable link ready.
The Sandbox
Safe by default. Limited by design.
The chef works in a safe zone. They can't accidentally break anything outside the boundaries. Good for safety. Means less flexibility than Code.
The Automatic Car
Easier to drive. Worse fuel economy.
Co-work uses more tokens than Code because extra orchestration runs under the hood. Fine for short tasks. Expensive at scale.
Scheduled work
Co-work can run on a schedule. Weekly client report every Monday. Daily LinkedIn summary. Monthly pipeline review. Set it once, it runs forever.

Insight 04
Code: The Chef Runs The Whole Restaurant
Full access, multi-agent workflows, persistent briefing. The most power at the best token economics.
The Manual Car
Harder to learn. Better fuel economy.
Code uses tokens efficiently once configured. Best choice at scale. Not for day-one users.
Multi-agent workflows
Five agents for the price of one.
Sub-agents share the prompt cache. Run research, drafting, and review in parallel without paying five times.
IDE stack
Where should Claude Code actually live?
Not sure? Start with the Desktop App. Move to Antigravity if you live in Google.
Insight 05
The Live Scenario Switcher
Pick a real task. See how each mode handles it side-by-side.
Pick a real task. See how each mode handles it side-by-side.
Perfect fit. Fast, conversational, no setup.
Talks through angles, pushes back, suggests pricing ladders.
Works but slow. No real benefit over Chat.
Would open a doc you don't need yet.
Way too much machinery for a thinking session.
Spins up a project you'll never use.
Best fit is highlighted with a gradient border. Try every scenario. The pattern becomes obvious fast.
Insight 06
The Memory Difference Is The Whole Game
Chat remembers every chat. Code and Co-work start fresh. One is a feature. The other is a risk.
Chat
Remembers everything across every chat
Your name, role, clients, preferences. Walk back in six months, it already knows you.
Risk: Client A context could leak into Client B answers.
Co-work & Code
Starts fresh every session
Knows nothing about you by default. Sounds annoying. Is actually a feature for client work.
[ clean desk on every session ]
Feature: Client A can never leak into Client B.
The fix for Code: CLAUDE.md
A plain text file that lives in your project folder. Tells Claude who you are, what the project is about, where important files live, and how you like to work. Get it right and Claude walks into every session already briefed.
Insight 07
MCPs: The Power Adaptor For Your Tools
Claude plugs into almost anything. The mode decides how much control you get over the plug.
The power adaptor
Your phone works in Australia. Europe needs an adaptor. An MCP is that adaptor.
You don't need to remember the acronym. Just know that Claude can plug into your tools. Chat has built-ins. Co-work adds more. Code gives you full control over what's connected and how.
