Why this helps
Review requests get acknowledged, but the follow-up to locate the asset can still slip through.
- Turns a deliberate reaction into a consistent lookup.
- Keeps the image search tied to the reviewed message.
- Makes existing alt text easy to inspect before feedback.
Setup
Build it in a few focused steps.
- 1Connect Slack and Alttext ai to Notis once through the portal.
- 2Create the automation in the portal or ask Notis to set it up conversationally.
- 3In one instruction, tell Notis to search Alttext ai for the image referenced by a review message when the agreed reaction is added, then report matching results.
- 4Choose Message Reaction Added and select a channel for run reports.
- 5Test by adding the agreed reaction to a real image review message.
