Quick verdict: choose Gemini if your business runs on Google Workspace, because it works inside Gmail, Docs, Sheets, and Drive and the $19.99 AI Pro plan includes 5 TB of storage. Choose ChatGPT if you want the most versatile standalone assistant with the widest range of third-party integrations. Individual plans cost about the same, so the deciding factor is where your team already works.

Which Is Better for Each Task?
Email and Documents
Edge: Gemini for Google Workspace users. Summarizing threads, drafting replies, and editing documents happen inside the apps. For Microsoft 365 users the advantage disappears.
General Writing and Analysis
Tie. Both handle drafting, summarizing, and spreadsheet analysis well. Test both on your own tasks.
Research
Slight edge: Gemini, thanks to Deep Research and Google Search grounding. ChatGPT’s research tools are also strong.
Images and Video
Tie for images; edge Gemini for video, which is included on paid Google AI plans.
Automation and Integrations
Edge: ChatGPT. It is supported by more third-party tools. Gemini works best when your workflow stays inside Google’s apps. See Zapier vs Make vs n8n.
Value
Edge: Gemini for users who also need cloud storage, since AI Pro bundles 5 TB.
