Get the gist of a 40-reply email thread before you scroll
A 40-reply reunion thread shrinks to who's bringing what, the final date and the one question left for you.
Published . Steps as of November 2026.
How do I quickly summarize a long email thread in Gmail?
Open the thread in Gmail and read the AI Overview at the top, which pulls out the key points and replies. That fits a quick check. If you need to know what you still owe, ask Gemini in Gmail the follow-up prompt, or copy the thread into ChatGPT or Claude. As of November 2026, AI Overviews and Help me write are rolling out to personal Google accounts 18 and older with smart features turned on.
A sketch of what you'll get back.
Your prompt
Fill in your details. Skip any you like.
ChatGPT and Claude open with your prompt already typed in. Gemini can't be filled in from a link, so its button copies your prompt: paste it into the new chat.
The prompt that gets copied
Here's a long email thread I've been avoiding: [PASTE THE THREAD] (or just say "this thread" in Gemini in Gmail). It's about [THREAD TOPIC, e.g. planning the family reunion]. I'm [YOUR NAME]. Give me: 1) what's been decided, in 3 bullets or fewer, 2) what's still open, 3) anything someone asked me directly that I haven't answered, with who asked, 4) any dates, amounts or deadlines mentioned, latest version only (if people changed their minds, show only the final answer). Then draft a short, friendly reply from me that answers the open questions aimed at me in under 80 words.
Open a long thread in Gmail and read the AI Overview at the top for the key points and replies, then ask a follow-up so you know exactly what's decided and what you still owe.
