Make personal follow-ups harder to lose
When a DM captures a commitment, create a compact visual cue with the person and next step.
Trigger
Direct Message Received
Triggered when a new direct message (DM) is sent to a user in Slack. Catches all DMs across all DM channels.
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
Small follow-ups in DMs are easy to forget once the conversation is closed.
- Bring a personal commitment back into view.
- Keep the next action tied to its context.
- Reduce the need to search old DMs for what you promised.
Setup
Build it in a few focused steps.
- 1Connect Slack and Html to image to Notis once.
- 2Create the automation in the portal or ask Notis in plain language.
- 3Give one instruction to create a follow-up prompt image when a DM to you contains a clear commitment.
- 4Choose Direct Message Received and select a run-report channel.
- 5Test with one real follow-up DM.
Questions about this workflow
Will this remind the other person?
No. It creates an image for you from the DM; it does not send a message to anyone.
What makes a useful prompt?
A clear person or context and one concrete next action make the visual more useful.
