Scrape webpage content using CSS selectors
A tool to extract structured content from a webpage by specifying css selectors. the tool navigates to the specified url, waits for the page to load (including parsing and executing javascript), and returns the selected elements in a structured json format.
Why this helps
A saved page may have changed by the time you return, leaving your old notes out of date.
- Refresh page details when you are ready to revisit the topic.
- Use an existing Slack action as a lightweight restart cue.
- Reduce uncertainty about whether an old note still matches the 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 in plain language.
- 3Tell Notis in one instruction to fetch current headings and selected page text when you remove your chosen reaction from a URL message, then report the source link.
- 4Choose the Slack reaction removed trigger, specify the intended reaction and channel if available, and pick a report channel.
- 5Test by removing the chosen reaction from one real public webpage message.
Questions about this workflow
Why use reaction removal as the signal?
It can serve as a deliberate cue that you are returning to a saved topic and want current page details.
Will it track edits continuously?
No. It fetches when the Slack reaction is removed; it is not continuous monitoring.
