Probes that show you what models actually say: and how to change it.
Auxy is the AI Visibility Platform. Probes run across Gemini, ChatGPT, and Claude to tell you what those models say about your brand. A Content Optimizer ships the line-level edits to change what they say next.

Selection rate is the new ranking signal.
For two decades the relevant unit of measurement in search was the click. A human read a result, decided to read more, and clicked through. The metric that mattered was CTR.
The shape of search has changed. Increasingly the entity choosing where to ground an answer is a model, not a person. The question to measure is no longer did a human click my link, it is did the model pick my content as the source it grounded on. That answer is being decided millions of times a day, and your visibility in AI search depends on it.
Auxy is built to measure that selection moment, diagnose why your content is or is not being picked, and produce the changes that move it.
Six probes that map your visibility surface.
Each probe is independently useful. Together they compose into a measurement-to-action pipeline.
Visibility Tracking. Nightly grounded probes against your tagged entities and locations. Per-entity and aggregate visibility scores across Gemini, ChatGPT, and Claude, with weekly drift alerts.
Citation Mining. Which URLs and domains the model actually cited for queries in your category. Aggregated, ranked, tied back to the prompts that surfaced them, broken down per provider.
Associations (E2B / Q2B / B2E). Three directional probes mapping which brands the model associates with your entities, with your queries, and which entities it associates with your brand. Confidence-scored.
Relevance Scoring. Binary yes/no probes asking each model whether your brand is relevant to a query or entity, repeated for statistical confidence. Trended over time, per model.
Page Grounding. Compares the grounded response against the source page line by line. Surfaces what survived, what was lost, and what was distorted. Line-level fidelity scoring against the claim.
Treewalker. Logprobs-based probing of what a model recalls about your brand without web search. Token-level confidence with alternative-token branches. Tells you if the gap is parametric or grounded.
Measurement that ships an edit, not just a number.
Measurement is the diagnostic layer. The treatment is the change you make on the page. Auxy ships both.
The Content Optimizer iterates on your page or its extractive snippet against a simulated AI ranker, learning what wins via Bayesian Beta-posterior updates over a seven-class rank-factor taxonomy. Every round produces a concrete, line-level edit with measured before-and-after lift attributable to that change.
What you hand your content team is a list of edits to ship. What you hand your board is the before-and-after on the visibility curve.
Multi-provider, mechanistic, property-scoped.
Auxy probes the same query in parallel across Google Gemini, OpenAI GPT, and Anthropic Claude. Each surface is treated as a first-class measurement target with its own grounding behavior, citation conventions, and parametric memory.
The working method is mechanistic interpretability: rather than guessing how a model decides, we probe it like a black box. Treewalker walks the logprobs token tree. Page Grounding reconciles claims against sources. Veracity scores fidelity per claim. Recommendations are evidence-led rather than folk theory.
Data lives in PostgreSQL, scoped per Property. Multi-property accounts, role-based access (Owner, Editor, Viewer), team membership, and an audit-friendly schema are built in. Backed by three years of LLM-grounding research at DEJAN.
