The honest take
Otterly.ai was one of the first AI search monitoring tools. The main difference is coverage and pricing. Otterly starts at $29/month with 3 search engines. SignalKit tracks 7 LLMs, starts free, and charges $1 per prompt with no tiers.
At Otterly's $29/month entry price, you could track 29 prompts on SignalKit across all 7 LLMs. Otterly gives you fewer prompts across 3 engines for the same cost.
SignalKit also exposes a REST API and MCP server on every account, including free. Otterly does not advertise an API, which makes it harder to integrate results into your own workflows.
