Capture a visual snapshot of a shared launch page

Give launch discussions a visual reference that is easy to revisit and compare.

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

Take Screenshot

A tool that captures a screenshot of a webpage using browserless's screenshot api. the tool takes a url and returns either a png or jpeg image. it includes options for full page capture, image type, quality, and clipping coordinates.

Why this helps

A page can change after feedback starts, leaving you unsure what the team was reviewing.

  • Keep a visual reference alongside the launch conversation.
  • Make feedback easier to ground in the page version people saw.
  • Reduce repeated trips back to a changing live page.

Setup

Build it in a few focused steps.

  • 1Connect Slack and Browserless to Notis once through the portal.
  • 2Create an automation in the portal or ask Notis to set it up conversationally.
  • 3In one prompt, ask Notis to capture a full-page screenshot for launch URLs shared in the chosen channel and report the source link.
  • 4Select the Slack channel message trigger and a channel for run reports.
  • 5Test by posting one real launch-page URL.

Questions about this workflow

Can the screenshot capture the full page?

The Browserless screenshot action supports full-page capture. Include that preference in your instruction.

Will it capture every channel message?

The prompt should specify that Notis should act on launch-page URLs, so unrelated messages are not treated as launch pages.
