Opplurk

Opplurk watches public pages and reports what changed. The user points it at a pricing page, changelog, careers board or product listing; Opplurk re-scrapes on a schedule, converts the page to clean markdown and hashes it so cosmetic churn such as whitespace or script tags does not register as a change. When the hash moves, it diffs the new version against the previous one line by line and stores both. Alerts reach Slack, email or a plain JSON webhook, optionally with an AI summary of what moved and why it might matter, and an AI noise filter scores changes against what the user said they cared about.
