The index of what AI recommends.

Each month, Citewake asks ChatGPT, Claude, Gemini and Perplexity the questions buyers ask. It keeps every answer, and measures who they recommend, who they cite, and which sources list whom.

The first index publishes early 2027. The method is public now.

Illustration of the method, not real results. One buyer's question goes to four AIs, each searching the web on its own. One reader goes through all four answers side by side and marks every brand by its role.

AI names three to five brands. Nobody can see why, or track it.

Ask an assistant for the best tool for a job and it gives you a short list, mostly the biggest names. Whether a brand is on that list now shapes who gets considered.

But each answer is private, the sources behind it shift, and tomorrow's answer may differ. There is no public record of what the AIs recommended, which pages they relied on, or how that changes month to month.

Citewake is that record. Fixed questions, asked the same way on a schedule, with every answer kept as evidence.

How it works

Every observation passes through three separate compartments, each with its own rules.

  1. The prompt

    The question goes to each AI exactly as written, through its official API. No memory, no custom instructions, no system prompt. Answers are never cached or reused; every observation is a fresh request.

  2. Each AI's own search

    Each AI searches the web with its own search, reads what it finds and answers. The search is never shared and never substituted, because which pages each AI finds and trusts is a large part of what Citewake measures.

  3. The analysis

    One judge, the grand master, reads all four answers to a question side by side, with their citations. It resolves each brand to the same entity in all four and holds every AI to one standard.

The grand master classifies. It doesn't judge.

For every brand in every answer it records the exact words, and the role: recommended, a neutral mention, or negative. A brand is kept only if its name, alias or domain appears in the answer text and the quoted words are found verbatim. It never adds a brand that isn't there and never adds an opinion.

Three measures, each with a fixed denominator

Each one counts one thing, so a young brand has real numbers that move before it is ever recommended. Every rate is shown per AI, per tier and overall, with a 90% interval.

Recommendation Rate

Cited-page Presence

How often the third-party pages the AIs cite list the brand.

Supporting, and labelled as such: Neutral and Negative Mention Rates, kept apart from recommendations; Competitive Share, which is relative and can fall when rivals gain; and Reported Retrieval Presence, shown per AI only where that AI's API reports it.

No combined score yet. A single 0–100 number is held until the pilot shows that combining the measures adds information beyond them, and that its weights hold on data they weren't tuned on.

Categories

Each category is defined by the job a buyer wants done, with stated boundaries. The first three are markets we know well, so every classification can be checked by hand. More follow as the index grows, each indexed when there's demand for it, and every lookup on this page counts.

Brands enter only through evidence: when an AI names them, or a cited page lists them. Nobody can submit, request or pay for inclusion. Products made by our team are in these categories, measured by the same rules with no adjustment. How we handle that.

Principles

The rules the index is held to, written into the method.

  • Every answer kept

    The full answer, its citations, and a snapshot of every cited page, forever. Any published number can be recomputed after the live pages change.

  • A public, versioned method

    The scored questions and the method are published. Any change makes a new version, dated in the changelog. Numbers are compared within a version only.

  • No paid inclusion

    Nobody can buy a place, a number or a correction. Our own brands are measured by the same code, with no manual adjustment.

  • Corrections added, not overwritten

    The original stays. A corrected figure is published beside it with the date, the cause and the evidence.
