SecondDoor and Otterly.AI
The affordable entry point to AI search monitoring, with a static readiness audit.
Claims about Otterly.AI checked August 2026. Their site.
What it is
Austrian-built Otterly monitors brand mentions and link visibility across AI search, from $29 a month, with higher tiers at $189 and $489. It holds a 4.8 of 5 rating across roughly 42 G2 reviews and integrates with Semrush. Its GEO Audit checks crawlability and content extractability, static checks that reviewers rate well at the price.
What it does well
- The lowest serious entry price in the category.
- A static readiness audit bundled with citation monitoring, which most Camp A tools lack entirely.
- Well reviewed for what it is, with no enterprise sales motion required.
Choose Otterly.AI when
- You want citation monitoring on a small budget and a basic readiness check in the same tool.
- You already work in Semrush and want the integration.
What SecondDoor measures that it does not
- A real walk instead of a static audit: SecondDoor drives a browser through your funnel twice on every scan, and unmeasured is reported as unmeasured rather than passed.
- The human to agent comparison and the Door Gap number.
- Fix files generated from your own scan evidence.

Common questions
Otterly's audit says my site is fine. SecondDoor found problems. Why?
A static audit checks that pages can be fetched and parsed. SecondDoor also attempts the journey: find the product or the signup, see a price, reach the point of action. Sites regularly pass the first test and fail the second, because the failure lives in the funnel rather than in any single page.
The comparison that settles it is your own site. A free scan takes about a minute and the report is permanent.
