What is Claude?

Claude is the AI assistant built by Anthropic, a company founded in 2021 by former OpenAI researchers with a specific focus on AI safety. Where some competitors chase flashy features, Claude has stayed narrower and more deliberate: a chat assistant that reads documents, writes and edits text, works through code, and reasons carefully about whatever you put in front of it. That restraint shows up in daily use as a model that tends to do what you actually asked, rather than what it assumes you meant.

The product has grown well beyond a single chat window. Alongside the web and mobile apps, Claude now includes Projects for organizing ongoing work, Artifacts for generating and editing documents, code and mini-apps inside the conversation, and Claude Code, a dedicated coding agent that can work across an entire codebase from the terminal or an IDE. Anthropic ships new model versions on a fairly regular cadence, and the underlying models have moved from a 200,000-token context window to a 1-million-token window on the top-tier models, which matters if you regularly paste in long documents, contracts, or large codebases.

Our verdict

4.7 / 5

Claude's strength is consistency: it follows instructions closely, handles long or technical material without losing track, and rarely needs to be re-prompted to get a usable answer. That focus comes at a cost — no built-in image generation, and a smaller add-on ecosystem than ChatGPT's. For writing, research, and coding work where precision matters more than extra features, it's one of the strongest options available; for users who want one app to also generate images or plug into a huge marketplace of third-party tools, it may need to sit alongside another assistant rather than replace it entirely.

FAQ

Is Claude free to use?

Yes. The Free plan gives access to Claude Sonnet 5 with daily usage limits. Paid plans raise those limits and unlock more capable models.

Can Claude generate images?

No, Claude does not generate images natively. It focuses on text, documents, code, and data analysis instead.

What's the difference between Claude Pro and Claude Max?

Pro is Anthropic's standard paid plan at $20/month. Max is a higher tier for heavy users who need substantially more usage, particularly for Claude Code.

Does Claude have a mobile app?

Yes, Claude has official apps for iOS and Android, alongside the web app and desktop apps for macOS and Windows.

What is Claude Code?

Claude Code is Anthropic's coding agent, used from the terminal, desktop app, or an IDE, that can plan and carry out multi-step coding tasks across a codebase.

How large a document can Claude handle?

Claude's top-tier models support context windows up to 1 million tokens, roughly several hundred pages of text in a single conversation.
