Show HN: Adversa – Monitor competitor websites with AI summaries

Hi HN,

I built Adversa to solve a problem I kept running into while working on SaaS projects: tracking competitor changes.

I was manually checking competitor pricing pages, landing pages, and feature pages to see if anything had changed. Tools exist that detect page changes, but they mostly send raw diffs or visual alerts.

Adversa monitors competitor webpages and uses AI to explain what actually changed and why it might matter. The goal is to filter out cosmetic updates and highlight meaningful changes like pricing shifts, new features, or messaging changes.

For example: • pricing updates • new product features • positioning changes on landing pages

Instead of sending raw diffs, the system generates a short explanation of the change.

The project is still early and I launched it today. I’d really appreciate feedback from the HN community, especially around:

• whether the summaries are useful • what competitor signals people actually care about • anything confusing in the product

Thanks for taking a look.
