Google Gemini
Google's AI assistant, deeply integrated with Workspace and Search.
Gemini is Google's AI assistant, with the advantage of tight integration into Gmail, Docs, Sheets and Search for users already in the Google ecosystem. It is available as a standalone chat app and embedded directly inside Workspace apps.
For teams already paying for Google Workspace, the integration can be more valuable than a separate assistant; for others it competes directly with ChatGPT and Claude on general capability.
