ChatGPT, Microsoft Copilot or Claude – which AI fits your working day? All three are powerful language AIs, but they have different strengths. Knowing them lets you pick the right tool instead of just the best-known one.

In short: ChatGPT is the versatile all-rounder with the largest ecosystem. Microsoft Copilot is the best choice if you work in Microsoft 365 (Word, Excel, Outlook, Teams) every day. Claude excels at long texts, careful writing and large documents.

ChatGPT: the versatile all-rounder

ChatGPT by OpenAI is the best-known language AI and a true all-rounder: writing texts, researching, developing ideas, generating images and much more. Thanks to its large ecosystem of apps and extensions, it is a good starting point for almost any task.

Microsoft Copilot: strong in the Microsoft 365 world

Microsoft Copilot plays to its strength right where you already work: inside Word, Excel, Outlook and Teams. It summarises emails, creates drafts and analyses data – and business data stays within Microsoft 365. Ideal for companies already using Microsoft 365.

Claude: strong with texts and documents

Claude by Anthropic is considered especially careful in writing and strong with long documents. It can process large amounts of text at once, summarise and edit cleanly, and also help with programming tasks.

Which AI should you choose?

If you work in Microsoft 365 every day, Copilot is the obvious choice. If you need a flexible all-rounder for many tasks, ChatGPT fits. For demanding, long texts or documents, Claude is strong. Many companies deliberately combine several models.
