ChatGPT vs Claude

ChatGPT

OpenAI's conversational AI assistant

ChatGPT is an AI assistant from OpenAI. People use it to ask questions, write and edit text, brainstorm, analyse documents and data, write and debug code, generate images, learn new subjects and carry out tasks, through a conversational interface on the web, desktop and mobile apps. Its launch in November 2022 marked a turning point for artificial intelligence. ChatGPT reached a huge user base faster than almost any consumer product before it, introduced the general public to large language models and started the wave of generative AI products and investment that followed. It remains the most widely used AI assistant. The product has expanded far beyond text chat. It can search the web and cite sources, analyse uploaded files such as PDFs and spreadsheets, run code to analyse data and create charts, generate and edit images, and hold real-time voice conversations. Custom GPTs let users and companies build specialised assistants for particular tasks, projects organise chats and files around a goal, memory allows it to remember preferences across conversations, and deep research produces long, sourced reports on complex questions. Agent capabilities let it carry out multi-step tasks on the web on the user's behalf. ChatGPT has a free tier and paid subscriptions that offer more capable models, higher usage limits and advanced features, plus Team and Enterprise plans with administration, privacy commitments and data controls for organisations. Developers access the underlying models separately through OpenAI's API. The limitations are those of current language models. It can state incorrect information confidently, its knowledge has cut-off dates unless it searches, and outputs need checking for important decisions. Privacy and data-handling policies matter for sensitive information, and organisations often prefer business plans that exclude their data from training. Alternatives include Claude from Anthropic, known for writing quality and long documents; Google Gemini, integrated with Google's services; Microsoft Copilot for Microsoft 365 users; Perplexity for answer-engine search with citations; Meta AI inside Meta's apps; and Mistral's Le Chat. Choose ChatGPT when you want the most widely used general-purpose AI assistant with a broad feature set.

Claude

AI assistant from Anthropic

Claude is an AI assistant made by Anthropic, an AI safety and research company. People use Claude to write and edit, analyse documents and data, research topics, write and review code, and work through complex problems in conversation, on the web, desktop and mobile apps. Anthropic was founded by former OpenAI researchers with a focus on AI safety, and that emphasis shapes how it describes Claude's development, including its constitutional approach to training models to be helpful, honest and harmless. Claude has developed a reputation for strong writing quality, careful reasoning and the ability to work with long documents, since its models support very large context windows that can take in entire reports, contracts or codebases at once. The product includes features for sustained work. Projects group conversations with shared files and instructions, artifacts display documents, code and interactive content alongside the chat so users can iterate on them, and research features search the web and compile sourced answers. Claude can connect to tools and data sources through integrations, including the open Model Context Protocol that Anthropic introduced, which lets AI applications connect to external systems. Claude Code is a command-line and IDE tool that lets developers delegate programming tasks to Claude in their own environment, and it has become widely used among software engineers. Claude has a free tier and paid individual plans with higher usage limits and access to more capable models, plus Team and Enterprise plans with administration and data controls. Developers and businesses access Claude models through Anthropic's API and through major cloud platforms. Like all language-model assistants, Claude can make mistakes, including stating incorrect information confidently, so important outputs should be verified. Usage limits on plans are a common consideration for heavy users. Alternatives include ChatGPT from OpenAI, the most widely used assistant; Google Gemini, integrated with Google Workspace; Microsoft Copilot for Microsoft 365; Perplexity for search-focused answers; GitHub Copilot and Cursor for coding; and Mistral's Le Chat. Choose Claude when you want an assistant suited to long documents, careful writing and coding work.
