Signum.AI tracks how a brand and its competitors appear in AI answers across ChatGPT, Perplexity and Gemini, with Claude, Grok and DeepSeek also shown on the homepage, and reports what drives those appearances. Features are visibility tracking, an AI visibility landscape showing competitors, source and citation analysis, monitoring of market signals such as reviews, news and website changes, an activity feed with email alerts, and recommendations for improving visibility.
Measuring whether a brand is named, cited or recommended in AI answers is the reporting layer generative-search optimisation lacks, and source analysis is the useful part: knowing which pages and publications the models draw on tells a team where to earn coverage. AI answers vary between runs and between users, so treat any visibility score as a sampled estimate and look at trends across a large set of prompts rather than single readings. The homepage cites customer results such as a 27% visibility increase for Mindshare and 35% more AI-generated answer appearances for MyFundedCapital; those are vendor-reported.
A free AI Checker tool gives partial data on visibility score, sources and industry landscape with no card. The Pro plan is $49 a month with email support, and Enterprise is custom and adds API and webhook integrations and a dedicated support manager; paid plans carry a 14-day money-back guarantee. The pricing page states no limits on prompts or tracked engines, so ask what the $49 covers before assuming it matches your prompt list. The site claims more than 4,000 users and a 4.9 G2 rating.
