Why this helps
Meeting preparation gets squeezed when context is shared in a DM and has to be reorganized from scratch.
- Reduce last-minute context gathering
- Clarify meeting goals and questions
- Create a brief that is easy to scan
Setup
Build it in a few focused steps.
- 1Connect Slack and Gamma to Notis once through the portal.
- 2Create Meeting Prep Brief as a new automation in the portal.
- 3Write one plain-language instruction asking Notis to turn meeting-related DMs into a short Gamma prep brief with background, goals, and questions.
- 4Select the Slack direct message trigger and choose a channel for run reports.
- 5Test with one real meeting context DM and check that the brief is useful before the meeting.
