Which AI tool should my SME choose?
Answer
The one that fits where your documents live: Copilot if you work in Microsoft 365, Gemini if you are on Google Workspace, ChatGPT Business or Claude Team if you want a standalone workspace. For an agent to act inside your software, you also need a connection to your systems: that is engineering work. Start by listing three repetitive tasks: the choice then almost makes itself.
Choose a business plan, never a free version for company data. Then test two tools for a week on three real tasks with five people, measuring quality, time and corrections. Products change every quarter: keep your instructions and templates in your own documents so that you can switch tools.
