Outcome

Looped into a never-ending email thread about planning a weekend trip, Android Police's Ben Khalesi tapped Gemini's summary in Gmail instead of reading about 20 messages. He says it returned a neat recap: the Airbnb in Perth booked for July 12–14, who was handling groceries, the 9 am meeting point and a reminder to bring sunscreen.

Prompt Recreated prompt

The source didn't share its exact prompt, so we wrote this from what it describes.

Run this task now, exactly as written below. Everything you need is here, so start straight away and only stop if something required is missing or a rule below tells you to.

Goal: Summarize this long email thread into the decisions, who's doing what, and anything I still need to do.

Fill in before running:
- The thread: [OPEN IT / PASTE IT]
- What I care about most: [dates, costs, my tasks]

Rules:
- List confirmed decisions separately from things still being discussed.
- Give each task with the person responsible.
- Include dates, times and places exactly as written in the emails.
- Don't reply to anyone.
- Check facts that can change (prices, opening hours, dates, availability, rules) against the official source, and tell me anything you couldn't verify.

Output: A short recap: decisions, who's doing what, meeting times, and my open to-dos.

You'll know it worked when: I could join the plan without reading the whole thread.
