Google is extending access to its Gemini AI side panel to personal Gmail accounts on Android devices, initially launched for Workspace applications in June. Users may need to restart their Gmail app to activate the feature, which is now appearing for non-Workspace users. The Gemini side panel enhances the email experience by summarizing threads, suggesting responses, assisting in drafting emails, and facilitating inquiries to find specific information. It is powered by the Gemini 1.5 Pro language model and aims to help users navigate lengthy email exchanges efficiently.
