OpenAIGeneral assistant for writing, analysis, images and research
by Google
Google's assistant, connected to Search, Workspace and Android
Gemini is Google's assistant, available as a standalone application and embedded across Gmail, Docs, Sheets, Meet, Chrome and Android. Its advantages come from that placement: it can draft inside a document, summarise a thread in your inbox, search your own files, and answer with live web grounding. It generates and edits images, analyses uploaded documents and video, offers a research mode that produces long sourced reports, and includes a canvas for iterating on documents and small applications. It suits Google Workspace users, Android owners and anyone who wants an assistant sitting where their work already lives. The limitations are consistency and control: quality varies between the standalone app and the in-product integrations, features roll out unevenly across countries and account types, and the most capable modes require a paid Google AI subscription that also bundles storage and other services you may not need.
Open gemini.google.com and sign in with a Google account; the free tier covers everyday use and a paid subscription unlocks the stronger models, longer research runs and higher generation limits. Connect the apps you use through the settings panel, since the assistant is far more useful once it can read your files, mail and calendar with permission. In Workspace, call it from the side panel of Docs or Gmail rather than switching to the standalone app, as the in-context version already has the document. Use deep research for anything requiring sources, and expect it to take several minutes and produce a long report you should check. Two practical notes: availability of individual features differs by country, account type and age, so a feature described online may simply not appear for you; and workspace administrators control whether the integrations are enabled at all, which is the usual reason a business account behaves differently.
