Make a launch brief visual in seconds
When your launch details land in Slack, turn the key message, date, and call to action into a ready-to-review visual.
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
Launch details are scattered in chat, making it easy to postpone the graphic or miss a key fact.
- Convert launch details into a consistent graphic without switching to a design app.
- Make the date and next step easier for teammates to spot.
- Keep launch preparation moving while the message is fresh.
Setup
Build it in a few focused steps.
- 1Connect Slack and Html to image to Notis once in the portal.
- 2Create an automation in the portal, or ask Notis to create one in plain language.
- 3In one instruction, ask Notis to make a launch graphic from each relevant Slack message and share the result in the run report.
- 4Choose Channel Message Received as the trigger and select a channel for run reports.
- 5Test with one real launch brief in Slack.
Questions about this workflow
What should the Slack brief include?
Include the launch name, date, key benefit, and call to action. Notis can use the message context to compose the graphic.
Can I review the image before sharing it?
Yes. Have the automation report the generated image so you can review it before using it elsewhere.
