What are the best AI tools for business?

Best overall AI stack for most businesses: ChatGPT Team/Enterprise for general productivity, Microsoft Copilot for Microsoft 365 if your company lives in Office, Claude Team/Enterprise for long-document work and careful writing, Google Gemini for Workspace for Google-based teams, and Zapier or Make for automating workflows across apps.

If you only choose one, pick the assistant that fits your existing work suite: Microsoft Copilot for Microsoft 365, Gemini for Google Workspace, or ChatGPT if you want the most flexible standalone AI workspace.
