Claude Code vs Claude.ai: What's the Difference?

Claude Code vs Claude.ai is a comparison that trips up a lot of people, including developers. Both are Anthropic products that use Claude models. That is where the similarity ends.

One is a browser-based chat interface for general knowledge work. The other is a terminal-based autonomous coding agent that reads files, executes commands, and manages your git repository. This article clears up exactly what each product is and which one fits your workflow.

Key Takeaways

• Claude.ai is a web chat product: It runs in the browser, handles conversation and document work, and requires no technical setup.
• Claude Code is a terminal coding agent: It runs in the CLI, accesses your filesystem, executes shell commands, and completes development tasks autonomously.
• Same models, completely different products: Both use Claude Sonnet by default, but the agent architecture, use case, and interface are entirely different.
• Claude.ai suits knowledge workers and general users: Writers, analysts, researchers, and anyone who needs AI assistance outside of a development workflow.
• Claude Code suits software developers: Engineers who want to delegate implementation tasks, run autonomous test-fix loops, or integrate AI into their CI/CD pipeline.
• Pricing overlaps but is not identical: A Claude.ai Pro subscription ($20/month) includes Claude Code access, but high-volume developer use requires Max ($100/month) or direct API.

What Is Claude.ai?

Claude.ai is Anthropic's browser-based AI assistant. It runs at claude.ai, requires no installation or technical configuration, and is designed for general knowledge work across all skill levels.

You open a browser, type a prompt, and receive a response. No terminal, no setup, no file access.

• Primary use cases are broad: Drafting and editing text, summarising documents, answering questions, analysing uploaded files, coding assistance in a chat context, and research.
• The interface is a conversation thread: Users type prompts and receive responses. There is no file system access, no command execution, and no autonomous task loops.
• Available on web, iOS, and Android: Designed for accessibility across devices and technical skill levels.
• Three plan tiers exist: Free (usage-limited), Pro ($20/month with higher limits and priority access), and Team/Enterprise for organisations.
• No local access of any kind: Claude.ai works with files you upload to the conversation. It cannot access your machine or run anything locally.

If you are looking for a native desktop app rather than a browser tab, see what Claude Desktop offers as an alternative to the web interface.

What Is Claude Code?

Claude Code is Anthropic's official CLI coding agent. It runs in the terminal via npm install -g @anthropic-ai/claude-code, requires Node.js 18+, and operates as an autonomous agent that completes multi-step development tasks.

This is not a chatbot with a dark background. Claude Code reads and writes your files, executes shell commands, manages git, and completes tasks without requiring a prompt after each step.

• Primary use cases are development-specific: Building features end-to-end, autonomous test-fix loops, codebase refactoring, debugging, documentation generation, and CI/CD integration.
• The interface is a terminal REPL: Claude Code runs in your terminal or headlessly in automation pipelines. There is no browser interface.
• Autonomous multi-step execution: Claude Code can plan, implement, test, fix, and commit without a human prompt at each stage.
• MCP integrations extend its reach: Claude Code connects to external tools and services via Model Context Protocol integrations, including direct Supabase database access.
• CLAUDE.md provides persistent project memory: A configuration file at the project root gives Claude Code context about the codebase and conventions across all sessions.

For the full technical picture of what Claude Code is and how it works, the complete guide to Claude Code covers its architecture, tool access, and setup in detail.

What Can Each One Do — and What Can It Not?

The clearest way to understand the difference is by capability. Claude.ai handles knowledge and conversation work. Claude Code handles implementation and execution work. They do not overlap.

The mistake most developers make is using Claude.ai for coding tasks and expecting it to execute. It explains and suggests. It does not implement.

<div style="overflow-x:auto;"><table><tr><th>Capability</th><th>Claude.ai</th><th>Claude Code</th></tr><tr><td>Draft and edit text</td><td>Yes</td><td>Limited</td></tr><tr><td>Summarise documents</td><td>Yes</td><td>No</td></tr><tr><td>Answer general questions</td><td>Yes</td><td>Yes (not optimised)</td></tr><tr><td>Code explanation in chat</td><td>Yes</td><td>Yes</td></tr><tr><td>Read/write local files</td><td>No</td><td>Yes</td></tr><tr><td>Execute shell commands</td><td>No</td><td>Yes</td></tr><tr><td>Run and fix tests autonomously</td><td>No</td><td>Yes</td></tr><tr><td>Manage git commits and branches</td><td>No</td><td>Yes</td></tr><tr><td>Integrate with CI/CD pipelines</td><td>No</td><td>Yes</td></tr><tr><td>Access the internet autonomously</td><td>No</td><td>Via MCP only</td></tr></table></div>

• Claude.ai cannot touch your machine: No local filesystem access, no command execution, no git management. These are hard limits, not feature gaps.
• Claude Code cannot replace a general assistant: It answers questions but is not optimised for research, writing, or document summarisation tasks.
• The execution gap is the key difference: Claude Code actually writes code into your files, runs it, and fixes it if it fails. Claude.ai suggests code you then copy and paste yourself.

How Do the Pricing Models Compare?

A Claude.ai Pro subscription at $20/month includes Claude Code access at the equivalent usage tier. Developers using Claude Code heavily will need Max ($100/month) or direct API access.

The confusion point is that Pro technically covers both products but at a usage level that does not support daily professional developer work.

• Free tier does not include Claude Code: The free Claude.ai plan gives browser access only. Claude Code requires at least a Pro subscription or an API key.
• Max ($100/month) adds Opus access: Claude Code Max includes Claude Opus for complex reasoning tasks and 5 times the usage of Pro.
• Direct API billing is per token: $3 per million input tokens and $15 per million output tokens for Sonnet 3.5. No subscription required. Most cost-effective for teams.
• Pro limits are real: Developers who run multiple Claude Code sessions daily will exhaust Pro tier usage. Plan for Max or API access if Claude Code is part of your daily workflow.

Which One Should You Use — and When?

Use Claude.ai for knowledge and writing work. Use Claude Code for software development work. Use both if you do both. They are not competitors; they serve different parts of a workflow.

The wrong-tool failure mode is common: developers who use Claude.ai for coding assistance and are frustrated that it "does not actually do anything" are using the wrong product.

• Use Claude.ai for writing and research: Document summarisation, drafting, Q&A, data analysis from uploaded files, and general knowledge work all belong in Claude.ai.
• Use Claude Code for development tasks: Building features, running test-fix loops, refactoring code, debugging, and integrating AI into a CI/CD pipeline belong in Claude Code.
• Use both if your work spans both: Claude Code in your dev environment, Claude.ai for everything else. They complement each other.
• Developers expecting execution from Claude.ai will be disappointed: Claude.ai discusses code. Claude Code implements it. That distinction is the whole article.

For further distinctions within Anthropic's developer-facing product line, Claude Cowork vs Claude Code explains the difference between collaborative and autonomous modes.

If Claude Code is the right fit, the guide to install and configure Claude Code takes you from zero to first session in under 15 minutes.

Conclusion

Claude Code and Claude.ai are not different versions of the same thing. They are fundamentally different products built for different users.

Claude.ai is a browser-based AI assistant for knowledge work. Claude Code is a terminal-based autonomous coding agent for software development.

If you are a developer, install Claude Code and run it on one real task today. If you need a general AI assistant, Claude.ai's free tier covers most use cases without any setup.
