Claude is an AI assistant built by Anthropic. But calling it a chatbot undersells what it has become. In 2026, Claude is an entire platform: a web chat, a desktop agent that controls your computer, a coding tool that lives in your terminal, a design tool that creates prototypes and slides, and an extension that works inside your own Chrome browser. It spans several products, each solving different problems.
The Claude Ecosystem in 2026
- Claude Chat ( claude.ai + mobile apps): Browser-based chat. Write, research, analyze, brainstorm. Projects for persistent context. Web search and memory built in.
- Claude Cowork: Autonomous agent. Reads and writes your files. Plugins, skills, connectors, scheduled tasks. Creates documents, spreadsheets, presentations, PDFs. Lives in the desktop app (macOS and Windows), and now also runs on web and mobile in beta.
- Claude Code (terminal CLI): AI coding agent in your terminal. Writes, tests, commits. Works directly in your codebase. VS Code extension available.
- Claude Design (design tool): Prompt-to-prototype. Slides, one-pagers, UI mockups. Applies your design system automatically. Exports to PDF, PPTX, HTML, or Canva.
- Claude in Chrome (browser extension): Claude in a side panel of your own Chrome. It can read the page you are on and, on paid plans, click through websites for you while you watch.
- Claude for Microsoft 365: Claude inside Excel, PowerPoint, and Word as add-ins, working directly in your real files.
- Claude API (developer platform): Build Claude into your own apps. Pay-as-you-go pricing.
There are more specialist corners (Claude Science for researchers, Claude Tag for Slack teams), but the ones above are what almost everyone uses.
Understanding the Models
Claude is not a single model. Anthropic offers a family of models, each optimized for different tasks. Knowing which to use is one of the most important things you can learn.
- Sonnet 5: The daily driver for writing, analysis, and everyday work.
- Opus 5: Deep reasoning and complex agent tasks.
- Fable 5.1: The premium tier above Opus. Anthropic's most intelligent generally available model, built for the hardest work.
- Haiku 4.5: The fast one, for quick, high-volume tasks.
The Claude 5 Family
The lineup runs Haiku 4.5 at the fast end, Sonnet 5 in the middle, Opus 5 for deep reasoning, and Fable 5.1 as the flagship at the top. Older models stay available in the picker if you have a workflow tuned to one.
Use Sonnet 5 for 80% of your work, Opus 5 for deep reasoning and long agent tasks, Fable 5.1 when you need maximum capability, and Haiku 4.5 when speed matters most.
Effort Control
You can control how hard Claude works on a response. The model menu next to the send button holds both the model choice and an effort setting: low, medium, high (the default), and on the top models an extra-high and max level. There is also a Thinking toggle that lets Claude reason step by step before answering (on Fable 5.1 and Opus 5, thinking is always on). Low effort is great for simple questions. High and above are better for complex research, analysis, and writing tasks.
Claude Design
Claude Design is Anthropic's design product, still labelled beta. It lets you collaborate with Claude to create polished visual work: prototypes, slides, one-pagers, pitch decks, and UI mockups. Think of it as having a designer on call 24/7.
What You Can Create
- Interactive prototypes from static mockups, shareable for user testing
- Slide decks from rough outlines, exportable to PDF, PPTX, HTML, or Canva
- Feature flows that product managers can hand off to developers
- One-pagers and marketing materials with professional layouts
- UI and UX mockups that follow your company's design system
Design System Integration
During onboarding, Claude Design builds a design system for your team by reading your codebase and design files. Every project after that automatically uses your colors, typography, and components. You can refine designs by commenting inline on specific elements, editing text directly, or tweaking spacing, color, and layout with live controls.
Claude Cowork
Cowork is the feature that turns Claude from a chatbot into a real agent. It runs inside the Claude Desktop app (macOS and Windows), can read and write files on your computer, execute code, search the web, and complete multi-step tasks autonomously. It is available on Pro, Max, Team, and Enterprise plans, and a beta version now runs on web and mobile too, with the local file work still happening through the desktop app.
Plugins
Plugins bundle skills, connectors, and sub-agents into a single install that turns Claude into a specialist. The plugin marketplace launched in February 2026 and includes plugins for legal, financial services, code review, and more. Install them from Customize > Plugins > Browse plugins. Paid plans only.
Skills
A skill is a markdown file that teaches Claude how to do one specific thing. Skills fire automatically when relevant context appears, and in Claude Code and the Microsoft 365 add-ins you can also trigger them directly as slash commands like /review-contract. You can create your own custom skills for workflows specific to your job, on every plan including Free.
Connectors
Connectors link Claude to external services: Google Drive, Gmail, Google Calendar, Slack, Outlook, SharePoint, OneDrive, Microsoft Teams, and more. Once connected, Claude can pull data from these services and act on it. Add them from Customize > Connectors.
Memory
Claude now remembers things across conversations. Memory is on by default for Free, Pro, and Max (off by default on Team and Enterprise), and you can see and edit everything it holds under Settings > Memory, organized into topics. If you would rather it remember nothing, turn it off in the same place.
Scheduled Tasks
Set Claude to run tasks automatically on a schedule. Daily morning briefings, weekly reports, hourly data checks. Scheduled tasks have access to your connectors, files, and skills, and they run in Anthropic's cloud on schedule, even when your computer is off or closed. The one exception is a task that needs a folder on your own machine, which has to run locally while the computer is awake. (Claude Code has its own version of this, called Routines, for scheduled coding automations.)
Claude in Chrome
Claude in Chrome is a browser extension from the Chrome Web Store that puts Claude in a side panel of your own browser. It can read the page you are looking at, summarize it, answer questions about it, and on paid plans it can act: clicking through sites, filling forms, and completing tasks in your logged-in sessions while you watch. Turn it on under Settings > Connectors > Claude in Chrome, then enable it per chat. It pauses before anything sensitive, and banking sites are blocked by default.
Claude Code
Claude Code is a command-line AI coding agent that lives in your terminal or VS Code. It reads your codebase, plans changes, writes code directly in your files, runs tests, and commits. Unlike chatting with Claude and copy-pasting code, Claude Code works directly in your project. Available with Pro ($20/mo), Max ($100-200/mo), or an API key.
Pricing Plans
- Free ($0/mo): Sonnet 5 and Haiku 4.5, limited messages, 5 projects, image analysis, web search, memory, skills, and connectors.
- Pro ($20/mo, or $17/mo billed annually): Opus 5, Sonnet 5, Haiku 4.5 and the older models, 5x usage, Claude Code, Cowork, Design, Science, Claude for Microsoft 365, and the Thinking toggle. Fable 5.1 is available on Pro but runs on pay-as-you-go usage credits from the first message, not on the plan's allowance.
- Max 5x ($100/mo): All models. 5x Pro usage, priority access, max output limits. Fable 5.1 is included up to half your weekly limit, then it switches to credits or another model.
- Max 20x ($200/mo): All models. 20x Pro usage, early features, highest limits, same Fable 5.1 rule as Max 5x.
- Team (from $25/seat, $20 on annual billing): All models, shared projects, admin controls, SSO. A premium seat tier with much higher usage runs $125/seat ($100 annual). Standard seats run Fable 5.1 on credits, premium seats get the Max rule.
- Enterprise ($20/seat/mo on annual billing plus usage at API rates): the self-serve version of the big-company plan, with admin controls over which models and effort levels people can use.
Pro at $20/month is the sweet spot for most people. You get Opus 5 and Sonnet 5, Claude Code, Cowork, Design, and unlimited projects. Upgrade to Max if you hit the usage cap regularly, or if you want Fable 5.1 as part of the plan rather than on credits.
