Claude AI is Anthropic’s flagship AI assistant, loved by writers and developers for its long memory, careful reasoning and natural writing voice.
What is Claude AI?
Claude is a conversational AI built by Anthropic, a company founded by former OpenAI researchers with a strong focus on AI safety and helpfulness. It is known for its long context window, nuanced writing style, careful reasoning and ability to follow complex instructions across very long conversations and documents.
You can use Claude for free at claude.ai, where you get access to a strong default model that handles writing, summarisation, coding, brainstorming, document analysis and research with impressive consistency. The paid Pro plan unlocks higher limits and access to the most advanced reasoning model.
Claude AI Key Features
- Massive context window. Claude can read entire books, long PDFs, codebases or research papers in a single prompt without losing track of the details.
- Natural, thoughtful writing. Many writers prefer Claude’s tone for blogs, essays and long-form content because it sounds less robotic than competitors.

- Projects and artifacts. Save reusable knowledge in Projects and let Claude build interactive artifacts like web pages, charts and small apps directly in the chat.
- Computer use and tool use. Advanced features let Claude operate a computer, call APIs and chain tools together for agentic workflows.
- Document and image analysis. Drop in PDFs, screenshots, spreadsheets or photos and ask Claude to extract, summarise or transform the content.
