In 30 seconds

Section titled “In 30 seconds”

Operators keep asking “which Claude do I use?” Chat is for conversations and quick tasks. Cowork is for autonomous multi-step work on your files. Code is for building and processing in a terminal. This page gives you a decision framework so you stop second-guessing which surface to open.

Decision tree

Section titled “Decision tree”

    A{What's the task?} -->|Quick question or brainstorm| B{Need file access?}
    A -->|Multi-step work on files| D[Cowork]
    A -->|Building software or data processing| E[Code]
    B -->|No| C[Chat]
    B -->|Yes, just reading| F{Complex or multi-file?}
    F -->|Simple, one file| C

    A -->|Browser automation| G{Extension or API?}
    G -->|Extension, point and click| H[Chrome extension]
    G -->|Programmatic, API-level| E

Start with the nature of the task, not the tool. The right surface follows from what you need to accomplish, not from habit or familiarity.

When to switch mid-task

Section titled “When to switch mid-task”

You do not have to pick one surface and stick with it. Many workflows benefit from starting in one place and moving to another.

Chat to Cowork. Start brainstorming or outlining in Chat. Once the plan is solid and you need Claude to create files, populate templates, or run multi-step processes, move to Cowork. Example: draft a reporting framework in Chat, then tell Cowork to build the actual spreadsheet and populate it from your data.

Chat to Code. You are discussing a data transformation in Chat and realise you need a script. Switch to Code to build it. Chat is great for figuring out what you want; Code is great for building it.

Cowork to Chat. A Cowork session produced a report. You want to discuss the findings, ask follow-up questions, or get a second opinion on the analysis. Copy the output to Chat for a conversational review.

Cowork to Code. Cowork automated a file-based workflow but you need something more robust, repeatable, or integrated with other systems. Code can turn that workflow into a proper script or pipeline.

Common mistakes

Section titled “Common mistakes”

Using Chat for file-heavy work. Chat can read uploaded files, but it cannot write to your filesystem, create folders, or process dozens of files in sequence. If your task involves creating or modifying files on your machine, you need Cowork or Code.

Using Cowork for quick questions. Cowork has startup overhead and is designed for autonomous, multi-step work. If you just need a quick answer, a rewrite of a paragraph, or a brainstorm, Chat is faster and simpler.

Defaulting to Code when you are not a developer. Code is powerful, but it runs in a terminal and assumes comfort with command-line tools. If you are an operator without a technical background, Cowork gives you most of the same file-processing power with a more approachable interface.

Forgetting about connectors in Chat. Many operators think they need Cowork to access Gmail or Slack. Chat also has connector access. If you just need to “check my Gmail for anything from Sarah today,” Chat handles that fine.

Running scheduled tasks in Code instead of Cowork. Cowork has built-in scheduling with /schedule. Code can do scheduling via cron, but it requires manual setup and maintenance. For most operator use cases, Cowork scheduling is simpler.

Five real examples mapped to the right surface

Section titled “Five real examples mapped to the right surface”

1. “Rewrite this email to sound more professional.” Surface: Chat. This is a quick, single-turn text task. Paste the email, get the rewrite, done.

2. “Go through my Downloads folder, rename all the Q1 invoices to a standard format, and move them to my Finance folder.” Surface: Cowork. This requires filesystem access, reading file contents, renaming, and moving files. Cowork handles this autonomously.

3. “Build me a Python script that pulls data from our API every hour and saves it to a CSV.” Surface: Code. This is a development task. Code can write the script, test it, and help you set up the cron job.

4. “Summarise the key themes from the last 20 Slack messages in #operations.” Surface: Chat. With the Slack connector enabled, Chat can pull and summarise this in a single response.

5. “Every Monday morning, check my Gmail, review my task list, and create a weekly priorities document in my Work folder.” Surface: Cowork with /schedule. This is a recurring, multi-step, file-creating workflow. Cowork’s scheduling feature was built for exactly this.
