Which one should you use?
Honest answer: it depends on where you work. Many people use both.
Choose GPT-6.1 Workspace if…
- Gemini isn't available on your account or plan
- You prefer GPT models for writing

Why people look for a Gemini alternative
Gemini's side panel in Gmail and Docs is powerful, but it depends on your account type, plan and region. GPT-6.1 Workspace works for any Google account in desktop Chrome, because it's a browser extension rather than a Workspace feature.
How GPT-6.1 Workspace reads your Google files without a Google login
It never asks for your Google password or API permissions. When you ask about an open document, the extension reads it through the session you already have in that tab — the same way your browser shows it to you. Nothing is read in the background. Learn how it works.
Can I use both?
Yes — they don't conflict. Some people use Gemini for Drive-wide questions and GPT-6.1 Workspace for writing help and for websites outside Google.
