Which AI should I use? / Gemini vs ChatGPT if you live in Google or Microsoft apps

⚖️ Gemini vs ChatGPT if you live in Google or Microsoft apps

“I use Gmail and Google Docs (or Outlook and Office). Which AI fits best?”

Short answer: If you live in Gmail, Docs and Drive, Gemini is the most natural fit, because it's built into those apps on paid Google AI plans. If your work runs on Microsoft apps like Outlook, Excel and Teams, ChatGPT and Claude both connect there: Claude offers Microsoft 365 and Outlook add-ins on paid plans, and ChatGPT can work in Teams and use Excel. For chores that cross both worlds, our everyday pick Grok Bot signs in to the tools you already use.

Tips

Turn on only the connections you need, and check what each one can read or change.
Use a work account's approved AI if your employer has one; don't move company files to a personal AI.
Ask for drafts, then read and send emails yourself.
Review connected apps every few months and remove ones you don't use.
