A quick AI summary lets you understand the context, decisions made, and action items without scrolling through the full history.<\/p>\n<h3>Expected benefits<\/h3>\n<ul>\n<li>5-10 minutes saved per long thread<\/li>\n<li>Faster context switching between conversations<\/li>\n<li>No missing important details buried in replies<\/li>\n<li>Easier to bring new people up to speed<\/li>\n<\/ul>\n<h3>How it works<\/h3>\n<p>Gmail thread reaches 10 messages -> trigger automation -> extract full thread content -> send to Claude API for summary -> create Gmail label with summary text or add as note -> optionally send summary to Slack\/email.<\/p>\n<h3>Quick start<\/h3>\n<p>Manually identify 3-5 of your longest active email threads. Copy them into Claude and create summaries. Test the format, then build automation for threads that cross the 10-message threshold.<\/p>\n<h3>Level-up version<\/h3>\n<p>Add structured summaries: key decisions, action items with owners, open questions, and next steps. Automatically update the summary when new replies are added.
