Mark a webpage for a screenshot with a reaction
A lightweight reaction can turn a shared page into a visual snapshot for the team.
Trigger
Message Reaction Added
Triggered when a reaction is added to a message in Slack. Supports optional filtering by channel and emoji name.
Action
Screenshot Webpage
Tool to take a screenshot of a specified webpage within a session. use when you need a visual png snapshot of a live page. example: "capture a 1280×720 screenshot of https://example.com".
Why this helps
A request for a visual check can disappear into conversation before anyone captures the page.
- Use a reaction as a clear cue for visual capture.
- Keep the screenshot request attached to the webpage message.
- Reduce the chance a small review task gets lost.
Setup
Build it in a few focused steps.
- 1Connect Slack and Anchor browser to Notis once in the portal.
- 2Create an automation in the portal or ask Notis to capture a screenshot when a chosen reaction is added to a message with a webpage link.
- 3Describe the reaction, linked page, and session context in one plain-language instruction.
- 4Pick the Slack Message Reaction Added trigger, configure its optional emoji or channel filter, and choose a run-report channel.
- 5Test by reacting to a real message with a webpage link and an available browser session.
