Slack are adding the ability to have unread messages in channels and threads summarised for you.
In channels and DMs, you can summarise just your unread messages, the last seven days or a custom date range (desktop only).
- Open the channel or DM you'd like to summarise.
- Click Summarise in the top right-hand corner.
- Choose an option to generate your summary, which will appear when it's ready.
- If you'd like, click the More details icon to view the summary's sources.
Note: Summaries can take longer to generate for larger time frames or message histories. We’ll notify you when your summary is ready, so feel free to take a break or move on to other work in the meantime.
