AI Assistant Built for Helpful, Harmless Conversations
What is Claude?
Claude is Anthropic's AI assistant for writing, research, document analysis, coding, and agentic work. Claude is known for careful reasoning, strong long-document handling, artifacts for live previews, Projects for shared context, and Claude Code for terminal-based software engineering workflows on supported paid plans. Current Claude subscriptions include Free, Pro, Max 5x, Max 20x, Team, and Enterprise options, with usage limits that vary by model, demand, and plan. Claude is built around Anthropic's safety-focused training approach and is widely used by teams that value nuanced writing, code review, and large-context analysis.
Key Features of Claude
Large Context Analysis
Claude can analyze long documents, PDFs, codebases, transcripts, and research material in one conversation. Higher-tier plans and enterprise offerings provide more room for heavy document and coding workflows.
Artifacts for Live Previews
Claude renders code, documents, diagrams, and prototypes in an interactive side panel. This makes it useful for drafting UI, editing documents, and iterating on structured outputs.
Projects with Custom Knowledge
Group related Claude conversations into Projects with shared files, instructions, and working context so repeated research or writing workflows stay grounded.
Claude Code
Claude Code brings Claude into terminal-based development workflows for codebase exploration, edits, tests, and refactors. Availability and limits depend on the current paid plan.
Vision and Document Understanding
Upload images, charts, PDFs, screenshots, and structured documents. Claude can summarize, extract, compare, and explain visual and written information.
Strong Writing and Coding
Claude is frequently chosen for polished writing, long-form reasoning, code review, debugging, and multi-file software tasks where careful explanations matter.
