Monitor Websites and Alert on Changes

Introduction

Staying on top of changes across the web is tedious when done manually. Dume Cowork can run scheduled checks on any public webpage, compare against a previous snapshot, and alert you the moment something meaningful changes.

How It Works

Dume Cowork opens a real browser session, reads the target page, and stores a snapshot. On each subsequent run, it compares the new content against the stored snapshot and reports any differences.

Setting Up a Monitor

Create a scheduled task in Dume Cowork:

Every Monday and Thursday at 9 AM:
1. Open [competitor pricing URL]
2. Extract all plan names, prices, and feature lists
3. Compare with the snapshot from the last run
4. If anything changed, send me a Slack message listing exactly what changed
5. Update the snapshot with the new data

What You Can Monitor

Controlling Alert Sensitivity

You decide what counts as a change worth reporting:

• "Only alert me if a price changes by more than 10%"
• "Ignore changes to the blog section — only watch the pricing table"
• "Alert me for any new job posting in engineering or product"

Stored Snapshots

Dume Cowork stores a plain-text snapshot of extracted content locally. It does not store full page HTML, only the structured data you asked it to track. Snapshots are cleared after 90 days by default.

Combining with Other Automations

Chain the monitor with downstream actions:

If the competitor adds a new pricing tier, create a Jira ticket for our product team titled "Competitor pricing update — review needed" and attach the details.
