●●SolidSolve My ProblemShip It

Competitor monitoring that filters noise with AI summaries—but Phantom Buster and native CI tools exist.

Strengths
  • •AI-driven noise reduction (cosmetic diffs excluded) is genuinely useful for alert fatigue
  • •Founding member co-development model invests users in product direction early
  • •Launched today with founder access model shows lean, responsive iteration
Weaknesses
  • •Semantic monitoring exists (Phantom Buster, Change Detection, built-in GA alerts) but not widely positioned
  • •No pricing published and no traction data; 'early' and 'built alongside small group' suggests pre-PMF

Post Description

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.
