Gemini is a catch-all hub for Google AI tools. It's not just a basic chatbot anymore — Gemini powers your Android voice assistant, works as the Spark personal productivity agent, and houses custom models like Omni. One such AI tool is the Gemini Daily Brief, which Google describes as an AI agent designed to preview your day in the morning. I already used a similar Google AI agent, CC, in Gmail for the same purpose. I wasn't in a rush to switch to Gemini Daily Brief for that reason, but after giving it a shot, I stopped checking my morning emails from CC.
