What Can Gemini Do in Gmail? 4 AI-Powered Features Worth Using

Email remains essential for work, but managing dozens—or even hundreds—of messages daily drains your productivity. Google recognized this problem and integrated Gemini directly into Gmail as an intelligent AI assistant. What's interesting here is that Gemini goes way beyond simple composition. It can summarize lengthy email threads, suggest smart replies, adjust tone and style, search using natural language, and extract key information from your messages. If you're looking to maximize Gmail's AI capabilities, this guide covers the most practical Gemini features you should be using.
