Claude AI: what it does, what it costs, and how to start

Claude is a general-purpose AI assistant built by Anthropic, an AI safety company valued at $380 billion with a $14 billion run-rate revenue. Think of it as a thinking partner for writing, analysis, research, brainstorming, and coding help. Anthropic calls it "a space to think," with no ads and no sponsored content.

You can access Claude through the web at claude.ai, desktop apps for macOS and Windows, mobile apps, or—if you're building software—through the API, AWS Bedrock, Google Vertex AI, and Microsoft Foundry. For most knowledge workers, the web and desktop apps are all you need.

One distinction worth making early: Claude (the chatbot at claude.ai) and Claude Code (a terminal-based coding agent) are different products. Claude is the conversational assistant you type questions into. Claude Code is a specialized agent that developers run from their terminal to write and edit software autonomously. Both use the same underlying models, but they serve different workflows. This guide focuses on Claude, the assistant. Curious how Claude stacks up against ChatGPT?

Claude comes in three tiers, each tuned for a different balance of intelligence, speed, and cost.

The quick guide: Pick Opus for complex reasoning and multi-step work. Pick Sonnet for everyday tasks where speed and quality both matter. Pick Haiku when you need answers fast and cheap—batch processing, quick lookups, high-volume automation.

Opus 4.6, the latest release, leads all frontier models on benchmarks like Terminal-Bench 2.0 (agentic coding) and Humanity's Last Exam. It also introduced adaptive thinking—the model reads contextual clues to decide how deeply to reason before answering, letting developers balance intelligence, speed, and cost without switching models.

Claude packs more features than most people realize. Here's what each one does and who gets access.

• Artifacts. Claude can generate self-contained content—documents, code, interactive apps—in a dedicated panel beside the chat. You can toggle between preview and code view, iterate in real time, and share artifacts via a public link. Available on all plans, including Free.

• Projects and knowledge bases. Organize conversations around specific topics. Each project carries its own custom instructions and document library, so Claude stays focused on your context. Paid plans only.

• Memory. Claude synthesizes summaries of your conversations and updates them every 24 hours. It learns your role, communication style, project details, and preferences over time. You can view, edit, pause, or reset memory in Settings. Paid plans only.

• Web search. Powered by Brave Search, Claude can pull live information from the web. No more stale answers on current events. Paid plans only.

• Advanced Research. Need a deep dive? Claude can research a topic for up to 45 minutes, searching the web, Google Workspace, and connected services simultaneously, then deliver a comprehensive report with citations. Available on paid plans.

• Integrations (MCP). The Model Context Protocol is an open standard—Anthropic calls it "USB-C for LLMs." Current partners include Atlassian (Jira/Confluence), Zapier, Slack, GitHub, and more. Team and Enterprise users also get connectors for Google Drive, Gmail, Calendar, and Microsoft 365.

• Claude Code. A terminal-based coding agent that independently accomplishes chains of complex tasks. Integrates with VS Code and JetBrains IDEs. Available on Pro, Max, Team, and Enterprise plans.

• Cowork (Computer Use). Claude interacts with your desktop—viewing your screen, clicking buttons, typing text. Currently a research preview on Max plans, available on macOS and Windows.

• Extended thinking. All current Claude models pause and reason through multi-step logic before responding, improving performance on complex reasoning, math, and coding tasks.

Consumer plans

The sweet spot: Pro at $20 per month is the best starting point for individuals. It unlocks every core feature—model selection, Projects, memory, web search, Claude Code, and integrations. The Max tiers are for power users who hit Pro's usage caps regularly.

Team plans

For small businesses, Team Standard gives you everything Pro offers plus SSO, spending controls, and shared connectors—starting at $20 per seat on annual billing.

Enterprise

Enterprise pricing is usage-based: a per-seat fee (billed annually) plus a shared organizational token pool at standard API rates. Two purchase paths exist—self-serve (credit card, no trials) and sales-assisted (invoicing, HIPAA-readiness, custom contracts). No public pricing; contact Anthropic's sales team. Enterprise adds audit logs, SCIM provisioning, custom data retention, and an enhanced 500K context window on Sonnet 4.5.

Freshness warning: Pricing changes frequently. All figures last verified February 2026.

Every AI tool has tradeoffs. Here are Claude's, stated plainly.

• Hallucinations. Like all large language models, Claude can generate plausible-sounding but incorrect information. Anthropic acknowledges this directly: "While these techniques significantly reduce hallucinations, they don't eliminate them entirely." Always verify critical facts.

• Knowledge cutoff. Claude's training data has a fixed cutoff—August 2025 for Opus 4.6. Web search (paid plans) fills the gap for current events, but Claude cannot know what it has not seen.

• No image generation. Claude can analyze images you upload, but it cannot create images, videos, or audio. For image generation, you need a different tool.

• Usage caps. All plans—including paid ones—have session-based and weekly usage limits. Anthropic does not publish exact numbers; limits vary by model, conversation length, and system demand.

• Over-cautiousness. Claude sometimes refuses requests that are safe. This stems from Anthropic's constitutional AI safety training. If Claude declines a reasonable request, try rephrasing.

• No persistent state without memory. On the Free plan, every conversation starts fresh. Even with memory enabled (paid plans), Claude stores synthesized summaries, not verbatim transcripts.

Since August 2025, Anthropic's data-sharing policy for consumer plans is opt-in, not opt-out. Here's how it works.

If you opt in to "Help improve Claude" (Settings > Privacy), Anthropic may use your conversations for model training and safety improvements. Retention: up to five years.

If you opt out, your conversations are retained for 30 days, then deleted. No training use.

How to check your setting: Go to Settings > Privacy > toggle "Help improve Claude" on or off.

Who this applies to: Free, Pro, and Max users only. Claude for Work, Claude for Government, Claude for Education, and API users (including AWS Bedrock and Google Vertex AI) are not affected—their data is never used for training.

One important detail: if you opt out after previously opting in, new conversations stop being used for training, but data already processed remains in the training set. For a deeper look at responsible AI policies, see AI governance.

Claude works best when you bring it a specific task. Here are eight ways knowledge workers use it every day.

• Drafting emails and reports. Paste your notes, tell Claude the audience and tone, get a polished draft in seconds.
• Summarizing long documents. Upload a 50-page PDF and ask for a one-page executive summary. Claude handles up to 200K tokens of context (1M in beta).
• Brainstorming campaign ideas. Describe your product and target market. Claude generates angles, taglines, and content hooks you can riff on.
• Analyzing spreadsheet data. Upload a CSV and ask Claude to spot trends, calculate metrics, or build a chart as an Artifact.
• Writing and debugging code. Describe what you want to build or paste an error message. Claude writes, explains, and fixes code across dozens of languages.
• Preparing meeting briefs. Feed Claude an agenda and background docs. Get a structured brief with key questions, risks, and talking points.
• Translating content. Claude handles translation with context awareness—it preserves tone, not just words.
• Research synthesis. Drop in multiple sources and ask Claude to identify agreements, contradictions, and gaps across them.
