# sirefs

> sirefs is an AI visibility tool and GEO audit. It tracks whether AI answer engines (ChatGPT, Google AI Overviews, Google AI Mode, Gemini, Perplexity, Microsoft Copilot, Claude, Grok) mention, rank, recommend and cite a brand compared with its competitors, shows which sources they cite, and audits how ready a website is to be read and quoted by AI engines. Tagline: "How are you being referenced by SIs?" Built by Uneven Bits ApS, Copenhagen, Denmark.

## Key facts

- Every engine on every paid plan: all 8 engines from Starter up. The free plan covers the six consumer-app engines.
- Unit: a prompt is one question in one market (country and language). Each prompt is checked on every engine in the plan, at the plan's frequency. No credits, no per-engine multiplier.
- Collection: the answers each consumer app shows a logged-out visitor, collected server-side through data vendors (method "ui", or "serp" for Google's AI Overviews and AI Mode). Claude and Grok can't be read logged out, so they come from the official APIs (method "api"). The method is shown on every number; methods are never mixed in one trend.
- Statistics: every rate comes with its sample size and a 95% Wilson interval; a change counts only when a two-proportion test gives p < 0.05 with at least 20 answers on each side.
- GEO audit: 26 checks in five groups (access, readability, identity, content, presence), scored 0 to 100. The free check shows 11 checks, a free account 22, paid plans all 26.
- Markets: 14 (US, UK, Canada, Australia, Ireland, Denmark, Sweden, Norway, Finland, Germany, Netherlands, France, Spain, Italy), each in its own language.
