About
Claude is an AI assistant built by Anthropic, an AI safety and research company founded in 2021. It handles writing, research, analysis and coding, and is widely regarded as one of the strongest assistants for long documents, careful writing and software development.
Writers, analysts, consultants and developers use Claude to draft and edit long-form text, summarise and compare large documents, analyse spreadsheets and build software. Developers often use Claude Code, Anthropic’s agentic coding tool, which works in the terminal, desktop app and code editors.
As of October 2026, Claude has a Free plan and a Pro plan at $20 a month ($17 a month billed annually). Max plans cost $100 or $200 a month for much higher usage, and Team and Enterprise plans add admin and security controls. API usage is billed separately per token.
Features and integrations
-
Long-Context Analysis: Claude can read and compare large documents such as contracts, financial reports, research papers and codebases in one conversation, and answer detailed questions about specific sections.
-
Projects: Projects keep files, instructions and chat history together for ongoing work, so Claude keeps the same context across many conversations and teams can collaborate on shared knowledge.
-
Artifacts: Claude can turn responses into standalone documents, web pages, interactive tools and charts that appear beside the chat and can be edited, published and shared.
-
Claude Code: Anthropic's agentic coding tool works in the terminal, desktop app and code editors. It reads a codebase, writes and edits files, runs commands and helps ship features and fixes.
-
Research and Web Search: Claude can search the web and compile cited answers or longer research reports, making it useful for market research, fact-finding and background reading.
-
Connectors and Agents: Claude connects to tools such as Google Drive, Gmail, Slack and Notion, and Anthropic offers agents for Chrome, Excel and PowerPoint that carry out tasks directly in those apps.
Pros and cons
Pros
- High-quality writing: Claude is known for clear, natural writing and good control over tone, which makes it a popular choice for reports, articles, proposals and editing work.
- Handles long material well: It can read and reason over large PDFs, contracts, research papers and codebases in a single conversation, which reduces the need to split work into small pieces.
- Leading coding tools: Claude Code lets developers hand off real coding tasks such as writing features, fixing bugs and reviewing pull requests from the terminal or desktop app.
- Shareable outputs: Artifacts turn Claude's answers into documents, web pages, interactive apps and charts that users can view, edit and share.
Cons
- No photo-style image generation: Unlike ChatGPT and Gemini, Claude does not create photo-realistic images, so visual content needs a separate tool.
- Usage caps: The Free and Pro plans have usage limits, and long sessions with large files can reach them faster than expected.
- Expensive power tiers: Heavy users and developers who need more capacity must move to Max plans at $100 or $200 a month.
