The honest take
Otterly.ai was one of the first AI search monitoring tools. The difference worth looking at is coverage and the shape of the bill. Their entry plan was published at US$29 per month for 15 prompts across 4 search engines, with extra engines as paid add-ons. SignalKit tracks seven AI platforms and charges US$3 per tracked question per region per month, with no tiers.
On those published figures, 15 questions in one region cost US$45 per month on SignalKit with all seven platforms, against Otterly's US$29 plan covering 15 prompts on 4 engines. That is not a like-for-like price: the platform sets, the monitoring schedules and what counts as a prompt differ, so compare the contents rather than the two numbers.
SignalKit exposes a REST API and MCP server on every account. Otterly's published plans include API and MCP access on Standard and Premium.
Common questions
Can I import my Otterly prompts into SignalKit?
Yes. Paste them into the prompt list when you create a project, or POST them to /api/prompts.
Does SignalKit track Google AI Overviews like Otterly does?
Yes. Google AI Overviews is one of the seven AI platforms SignalKit tracks, available on every account. It is measured through SerpAPI rather than a chat API, and it runs on Mondays and Thursdays rather than daily.
