About us

We watch the web so your team doesn't have to.

Page Deltas started with a simple frustration: keeping tabs on competitor pricing, public docs, careers boards, and policy pages meant refreshing the same tabs over and over — and still missing the changes that mattered. So we built a platform that does the watching for you, and uses AI to tell you only about the changes worth knowing.

Our mission

Page Deltas is built for product, marketing, and competitive intelligence teams who can't afford to be the last to know. We fetch the pages you care about on a schedule, extract the meaningful content, and run every detected change through an LLM that filters out the noise and summarizes what actually changed. When something matters, we ping you wherever your team already works — Slack, Discord, Microsoft Teams, email, or a signed webhook.

What we believe

Signal over noise

The web changes constantly, and almost none of it matters. Everything we build is in service of surfacing the handful of changes that actually do.

Build it to last

Monitoring is only useful if you can trust it. We invest in robust infrastructure that keeps working across 99% of the public web, day in and day out.

Respect your time

We'd rather send you one perfect alert than ten you have to triage. AI does the filtering and summarizing so your inbox stays calm.
