Make Slack decisions easier to remember
Turn a decision shared in a channel into a compact visual record with the outcome and next step.
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
Convert HTML to Image
Tool to convert HTML content into an image. Returns either a downloadable file or a JSON payload containing id and url, depending on the upstream API behavior.
Why this helps
Important decisions get lost in discussion threads, leaving people unsure what was agreed.
- Make the agreed outcome easier to find in a channel.
- Keep the next action visible alongside the decision.
- Reduce repeated clarification messages.
Setup
Build it in a few focused steps.
- 1Connect Slack and Html to image to Notis once.
- 2Create an automation in the portal or ask Notis to create it in plain language.
- 3Write one instruction asking Notis to create a decision card from messages that state a clear decision.
- 4Select Channel Message Received and choose where run reports should appear.
- 5Test with one real decision message.
Questions about this workflow
Will it identify decisions from every discussion?
Use a clear Slack message stating the decision, and phrase the instruction to create a card only when an outcome is explicit.
Can the image be treated as the permanent record?
The original Slack message remains the source. The image is a convenient visual summary.
