Keep Your Decisions Visible: From Slack Chatter to Notion Action Items
You decide something in Slack. Five hours later, you've forgotten the nuance. With this automation, key decisions become live Notion tasks you can't miss.
Trigger
Channel Message Received
Triggers when a message is posted in a channel, excluding direct messages.
Action
Insert row database
Creates a new page as a row in a database.
Why this helps
Neurodivergent founders often struggle with working memory. Decisions made in Slack threads feel urgent in the moment but vanish from focus when you switch to other apps. By the time you return, the context is gone, and the decision either repeats or falls through.
- Preserve decision context in one searchable place without re-reading threads
- Reduce working memory load by offloading to Notion's persistent record
- Catch decisions that would otherwise fall through cracks between apps
Setup
Build it in a few focused steps.
- 1Connect Slack and Notion to Notis (one-time setup in the portal).
- 2Ask Notis in plain language: 'When I post a decision in the team Slack channel, create a task in my Notion task database with the full message so I can find it later'.
- 3Select 'Channel Message Received' as your trigger.
- 4Choose a Slack channel where your team discusses decisions.
- 5Pick a Notion database to store your decision tasks, then test with a real message in the team channel.
Questions about this workflow
Will every Slack message create a Notion task?
No. Notis uses your plain-language instruction to decide which messages matter. Tell Notis which channel to watch and what kind of messages count as decisions (e.g., 'messages starting with DECISION:'), and it filters the rest.
Can I add extra context like the author's name or timestamp?
Yes. Your Notis prompt can ask for any metadata you want Notis to capture, such as the author, timestamp, or thread link. Notis will pull that information automatically.
What if I need to filter by reaction instead of channel message?
Use the 'Message Reaction Added' trigger instead. Team members can react with an emoji (e.g., 'pushpin'), and Notis will create the task only on reacted messages.
