🔗 Which AI is best at combining information?
Combining information – that is, gathering several sources, documents, or topics into one – is one of the most valuable uses of AI. Here, the trio clearly differs.
🔍 Google Gemini – best for combining public information
Gemini retrieves information in real-time from multiple sources and displays source links. The paid Deep Research mode automatically analyzes dozens of sources at once – the best tool for research.
🧠 ChatGPT – excellent for analyzing your own documents
In the ChatGPT Plus version, you can upload multiple files (PDF, Word, Excel) and ask the AI to combine their information. The memory feature maintains context across multiple conversations.
🏢 Microsoft Copilot – best for combining a company's own data
Copilot directly accesses content from SharePoint, OneDrive, and Outlook – without you having to copy anything. The best choice when you want to combine a company's own documents, emails, and meeting notes.
💡 Summary: For combining public information → Gemini. For analyzing your own files → ChatGPT. For compiling internal company data → Copilot.
🎨 Images and writing – which AI excels?
Creating images and quality writing are two different things – and different AIs excel at them in different ways.
🧠 ChatGPT – best for writing and image creation
ChatGPT is clearly the best of the three for creative writing – blog posts, marketing texts, stories, and social media posts are generated quickly and with high quality. The Plus version also has DALL-E 3 directly integrated – you can create images from text descriptions within the same conversation.
🔍 Google Gemini – image analysis, not creation
Gemini is excellent at image analysis – you can upload an image and ask Gemini to explain what it shows. Image creation is possible in the Advanced version with the Imagen model, but the quality does not reach DALL-E 3's level.
🏢 Microsoft Copilot – images with Designer, writing in Office context
Copilot uses Microsoft Designer for image creation (DALL-E-based). For writing, Copilot particularly excels in Office documents – drafting Word reports, PowerPoint presentations, and Outlook messages.
💡 Summary: Creative writing + image creation → ChatGPT Plus. Image analysis → Gemini. Office documents → Copilot.

ChatGPT is the most versatile – best for writing and coding, but the free version does not retrieve information in real-time. Microsoft Copilot is superior in the Microsoft ecosystem, but its full benefits require an expensive M365 subscription.
