Claude

What is Claude?

Claude is Anthropic’s AI assistant that writes and edits text, analyses long documents, researches topics and writes code from plain-language prompts. Anthropic, an AI company founded in 2021, offers it on web, desktop and mobile.

Claude AI runs on a family of language models named Opus, Sonnet and Haiku, trained with a written set of principles that Anthropic calls a constitution.

Key Features

Claude’s key features are long-document analysis, web search, Artifacts and file creation, Projects and memory, connectors to other apps, a Research mode and the Claude Code coding agent, on web, desktop and mobile.

• Long-document analysis: Reads and reasons over large files in one conversation, so you can summarise a report, compare documents or question a contract without splitting it into parts.
• Web search: Brings current information into answers. Anthropic lists web search in the Free plan, so it does not need a subscription.
• Artifacts and file creation: Builds documents, spreadsheets, slides and small apps you can keep. The Free plan can create Artifacts and create or edit files using code execution.
• Claude Code: A coding agent that works in your terminal and codebase. It is included from the Pro plan at $20 a month, or $17 a month billed annually.
• Projects and memory: Keep files, instructions and context together across chats. Free accounts get up to 5 projects and memory across conversations, and Pro makes projects unlimited.
• Connectors and extensions: Link Claude to the apps and tools your team already uses, on every plan including Free. Pro adds Claude in Chrome and Microsoft 365.
• Research and scheduled tasks: Pro adds the Research feature for longer investigations and lets you hand off and schedule tasks, so Claude can work on a job in the background.
• Model choice: Claude runs on the Opus, Sonnet and Haiku model families. Paid plans unlock more Claude models than the Free plan offers.
• Voice mode and incognito chats: Both are listed in the Free plan, so you can talk to Claude or keep a conversation out of your history without paying.

Pros

Claude’s main advantages are natural long-form writing, strong coding through Claude Code, a free plan that includes web search, memory and file creation, and admin and security controls on Team and Enterprise.

• Writing quality: Produces natural, well-structured long-form text, which makes it a common choice for reports, articles and careful editing.
• Strong at coding: Claude Code is included from the Pro plan at $20 a month, so developers get a terminal coding agent without a separate purchase.
• Capable free plan: Web search, memory, file creation, code execution, Artifacts, connectors and up to 5 projects cost nothing. Usage limits are the main difference from paid plans.
• Clear upgrade path: Max starts at $100 a month and offers 5 or 20 times more usage than Pro, with higher output limits and priority access at busy times.
• Business controls: Team adds SSO, central billing and admin controls from $20 per seat a month on annual billing. Enterprise adds SCIM, audit logs, a compliance API, custom data retention and IP allowlisting.
• Runs on every main platform: Claude works on the web, in desktop apps for macOS and Windows, and in iOS and Android apps, with the same account and chats.
• Published principles: Anthropic trains Claude with a written set of principles it calls a constitution, so the rules for how it should behave are public.

Cons

Claude’s main drawbacks are that it has no built-in image generator, Free and Pro usage is capped by five-hour and weekly limits, exact limits are not published, and heavy use costs $100 a month or more.

• No image generation: Claude does not create images natively. Anthropic’s pricing page lists no image generator, so you need a separate tool for AI images.
• Usage limits: Free and Pro users can hit caps during heavy use. Pro has a session limit that resets every five hours plus a weekly cap across all models, according to Anthropic’s help centre.
• Limits are not published as numbers: Anthropic describes Pro only as “more usage” than Free. The real allowance varies with message length, attached files, conversation history and the model you pick.
• Heavy use is expensive: Max starts at $100 a month, and Team premium seats cost $100 per seat on annual billing or $125 monthly, five times the $20 to $25 standard seat.
• Enterprise cost is hard to predict: Enterprise is priced at $20 per seat a month plus usage billed at API rates, so the total depends on how much each team uses it.
• Can be cautious: It sometimes declines or hedges on borderline requests, which can slow down work on sensitive but legitimate topics.
• Answers need checking: Like any AI assistant, it can be wrong. Check figures, quotes and any legal, medical or financial point against an original source.

Who is Using Claude?

• Developers: Write, review and debug code.
• Writers and marketers: Draft and edit long-form content.
