I’ve been building Adversa [1], a tool that monitors competitor websites and explains what actually changed.
Most monitoring tools alert every time anything changes. That usually ends up being navigation tweaks or small copy edits. After a while the alerts just get ignored.
Adversa focuses on meaningful updates instead. It detects changes across competitor pages and uses AI to summarise what changed and why it might matter.
I originally built it because I was manually checking competitor pricing pages and changelogs. I also wanted something practical for smaller SaaS teams. A lot of existing tools are either enterprise-priced or the free tiers are too limited to be useful.
Still early and trying to learn what people actually want from this kind of tool.
