Keep the exact review state available while feedback moves forward.
Trigger
Message Reaction Added
Triggered when a reaction is added to a message in Slack. Supports optional filtering by channel and emoji name.
Action
Take Webpage Snapshot
Tool to capture rendered HTML and screenshot of a webpage. Use when you need both DOM content and an image in one request with custom loading and capture settings.
Why this helps
Design review links change quickly, so the reviewed version can disappear before decisions are recorded.
- Preserves the visual and HTML state under review.
- Creates a simple handoff artifact for designers and founders.
- Reduces repeated screenshots and version confusion.

- 1Connect Slackbot and Cloudflare browser rendering once in Notis.
- 2Create an automation named Design review snapshot request.
- 3Tell Notis to snapshot the URL in any message receiving the agreed review reaction and include the message context.
- 4Pick Message Reaction Added as the trigger and choose where run reports go.
- 5Test by reacting to one design review link.
