What Is claude.com — Claude's Official Service Operated by Anthropic
claude.com is the official web service for "Claude," the AI assistant developed by Anthropic, an AI safety research organization. While claude.ai was the common URL in the past, claude.com is now the official address, and the Japanese version is accessible at claude.com/ja.
The site's tagline is "Think fast, build faster." It is positioned as a service that delivers two core values: quickly organizing your thinking through chat, and rapidly executing real tasks with Cowork and Claude Code (Source: claude.com).
Among generative AI services alongside ChatGPT and Gemini, Claude is particularly known for long-document processing, coding assistance, and safety considerations. As of 2026, multiple models are available including Sonnet 4.6 as the flagship, along with Opus 4.8 and Haiku 4.5.
Access URLs and Supported Devices
You can access Claude's official service through the following channels.
| Access Method | URL / Where to Get It |
|---|---|
| Web browser | claude.com |
| iOS app | App Store — "Claude" |
| Android app | Google Play — "Claude" |
| Desktop app | Download from claude.com (Mac/Windows) |
The browser version requires no additional installation, making web access the fastest way to get started. The desktop app offers conveniences not available in browsers — such as pinned windows and notification integration — making it well-suited for developers and power users.
Features Available on the Free Plan
The Free plan is completely free with no credit card required. Key features are as follows (Source: claude.com/pricing).
- Chat: Conversations with the latest model (Sonnet 4.6). Fully supports Japanese
- Code generation: Writing and debugging code in multiple languages including Python, JavaScript, and SQL
- Web search: Real-time supplementary search for the latest news and public information
- Artifacts: Preview HTML/React components, graphs, and documents in-place and generate shareable URLs
- File uploads: Attach PDFs, images, and text for data analysis
- Conversation history: Past sessions are automatically saved and can be referenced continuously
The Free plan has usage limits, and once you reach the daily message cap, temporary restrictions apply. When you find yourself hitting those limits frequently, that is a good signal to consider upgrading to a paid plan.
Pro and Max Plan Pricing and Differences
| Plan | Monthly Price | Key Additional Features |
|---|---|---|
| Free | Free | Core features: chat, web search, Artifacts, etc. |
| Pro | $17/month (annual) – $20/month (monthly) | Claude Code, Claude Cowork, Claude Design, multi-model selection |
| Max 5x | From $100/month | 5× the usage of Pro, priority access during peak load |
| Max 20x | From $200/month | 20× the usage of Pro, early access to all features |
Pro includes all Free features plus Claude Code (terminal-integrated coding), Claude Cowork (task delegation and file operations), and Claude Design (UI design generation). For individual users who regularly use coding assistance or complex document creation, Pro offers excellent value for money.
Max is aimed at power users who want to avoid hitting usage limits during intensive work sessions. It is suited for use cases such as API development or large-scale content processing that involve sending many messages per day.
Team and Enterprise Plan Overview
Two plans are available for organizations.
Team costs $20 per seat per month (standard) or $100 per seat per month (premium — 5× the usage of standard), and supports SSO (Single Sign-On), a centralized admin console, and enterprise search integration. It is ideal for teams using Claude across multiple members.
Enterprise includes features for organizations with strict security requirements, such as HIPAA compliance, SCIM provisioning, audit logs, and custom data retention settings. Pricing is based on a custom quote, so you will need to contact Anthropic through the form on the official website.
6 Key Features on the Site
Artifacts — Output Code, Documents, and Visuals In-Place
Simply type something like "Create an HTML landing page" in the chat, and the resulting artifact — complete with a preview — appears in the right pane. You can also use the Publish feature to generate a URL and share it with others.
Projects — Organize and Continue Topic-Based Conversations
You can divide workspaces by topic — such as "coding assistance" or "marketing strategy review" — and manage conversations accordingly. Related files and past insights are accessible within the same project, allowing you to continue working with full context carried over.
Web Search — Real-Time Supplementation with the Latest Information
This feature compensates for the knowledge cutoff (the date beyond which Claude's training data does not extend). Search queries are automatically appended to your prompt, providing answers that cite the latest news, research findings, and exchange rates.
Claude Code — Terminal-Integrated Development Support
You can call Claude from IDE extensions for VS Code, JetBrains, or the terminal to request code reviews, bug fixes, and test generation. Its greatest strength is making consistent changes across multiple files (available on Pro plans and above).
Claude Cowork — Task Delegation and Autonomous Execution
You can delegate browser operations, file generation, and external tool calls to Claude. This enables autonomous task processing that goes beyond simple conversational responses — for example, "Fill out and submit this form" (Pro plans and above).
Extended Thinking
For questions requiring complex mathematics or multi-step reasoning, Claude expands its thinking steps internally before answering. This can be toggled alongside quick-response mode depending on your use case.
Differences Between the Web, Desktop, and Mobile Apps
| Feature | Web | Desktop App | Mobile App |
|---|---|---|---|
| Installation | Not required | Required (Mac/Win) | Required (iOS/Android) |
| Voice input | Browser-dependent | ○ | ○ |
| Notifications | ✗ | ○ | ○ |
| Pinned window | ✗ | ○ | — |
| Push notifications | ✗ | ○ | ○ |
For getting started quickly, the web version is the easiest choice. For continuous use on a PC, the desktop app is recommended. If you want to use Claude on the go or take advantage of voice input, the mobile app is the right fit. Since all platforms share the same account, you can also mix and match depending on your needs.
