Use Gemini to clear email and compare trip options

A writer used Gemini Agent Mode to sort recent mail and help book a Tokyo hotel while leaving final approval for later.

What they did
Amanda Caswell turned on Agent Mode in Gemini 3.1 Pro and pointed it at her Gmail. She asked it to scan the past day of messages, pull out items that needed a response, archive newsletters she had already handled, and prepare a draft reply to the newest email. She then used it for travel planning, asking for a Tokyo trip so Gemini could open booking sites through Project Mariner and check live room prices.
How it went
Gemini archived the mail and left reply drafts ready for her to review. For the trip, it compared hotel rates and placed a 24-hour hold on a room. The account did not include timing data or any other measured result.
Tips
Keep a final review step before anything is sent or booked. Agent Mode requires a Pro or Ultra plan, and the draft still needs your click before it goes out.
