Every Announcement Becomes Changelog History: Slack to Notion
Your team announces a new feature in Slack. Notis automatically adds it to your Notion changelog so users and stakeholders can find the update in one reliable place.
Trigger
Channel Message Received
Triggered when a message is posted in a Slack channel (public, private, or multi-party IM). Does NOT match direct messages.
Action
Add multiple content blocks (bulk, user-friendly)
Efficiently adds multiple standard content blocks to a notion page in a single api call with automatic markdown parsing. the 'content' field in notionrichtext blocks now automatically detects and parses markdown formatting including headers (# ## ###), bold (**text**), italic (*text*), strikethrough (~~text~~), inline code (`code`), links ([text](url)), and more. ideal for bulk content creation, ai agents, and replacing multiple individual add page content calls. supports automatic text formatting, content splitting, and up to 100 blocks per request.
Why this helps
Announcements happen in Slack but never make it to your public changelog. Neurodivergent founders struggle to maintain a consistent, up-to-date product changelog because updates are announced everywhere except where they need to be. Users miss important features, and the team loses track of what's been shipped.
- Keep your changelog current without manual copying
- Ensure users and stakeholders always know what's new
- Create a permanent, searchable record of all product announcements
Setup
Build it in a few focused steps.
- 1Connect Slack and Notion to Notis in the portal.
- 2Tell Notis: 'When the team posts an announcement in the announcements channel, add it to my Notion changelog with the date, feature description, and impact on users.'
- 3Select 'Channel Message Received' as your trigger and specify your announcements channel.
- 4Point Notis to your Notion changelog page or database.
- 5Test by posting a sample announcement and verify it appears in Notion.
Questions about this workflow
Can Notis format the changelog entry automatically?
Yes. Tell Notis the format you want (e.g., 'date - feature name - brief description - user impact') and it will structure entries consistently.
Can I tag announcements by feature, team, or priority?
Absolutely. Your Notis prompt can ask it to analyze the announcement and add tags like 'backend feature,' 'UI improvement,' or 'critical update.'
What if I want to filter out internal-only announcements?
Tell Notis to only log announcements from specific channels (like 'customer-updates') or that contain certain keywords, and skip internal-only messages.
