Why this helps
A quick check can slip away when turning it into a separate task feels like extra overhead.
- Capture one-off checks in the place you already send requests.
- Keep the requested steps and result together.
- Reduce the mental load of remembering to test later.
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 in plain language.
- 3Use one instruction to run only the requested safe browser inspection for URLs you DM and summarize what happened.
- 4Select the Slack direct message trigger and a channel for run reports.
- 5Test with one safe page and a clear inspection request.
