Pill is prominence, 0–100. Every row opens the answer it was scored from.
A different instrument. Search told you where you ranked. The answer layer decides whether you are named at all.
FIG.01
Measured, not modelled
Every score is computed from answers that are stored verbatim. Where nothing was measured the cell says so with an em dash.
FIG.02
Traced to the sentence
Open any number and the reply it was read from is underneath it, exactly as the engine returned it.

5 engines, one loop
ChatGPT, Claude, Gemini, Perplexity and Grok, each queried through its own official API on the same prompt set.
01Where the blind spot is
Your buyers already moved to the answer layer, your measurement hasn't
Analytics stop at the click
Search Console tells you where you rank. It says nothing about what ChatGPT told a buyer this morning, because that conversation never reached your site.
An answer names one winner
A results page lists ten options and lets the reader choose. An answer names a brand — and every answer that skips you is naming someone else.
Models describe you from memory
What an engine says about your pricing, your category, your founding year is assembled from whatever it absorbed. Nobody is checking it against your own site. That is the part that gets expensive.
02Measure
Every engine, one evidence base
Your buyers' questions go to every engine through its official API. Each answer is stored exactly as it came back, then scored — named or not, how prominently, in what tone.

They can only cite what they can read
An engine that cannot fetch your pages will answer from memory instead. Synthic checks all 16 AI crawlers against your robots.txt and headers, and shows which ones are being turned away.

The stakes
The shift already happened. The measurement is what's missing
Every figure here is somebody else's published research, linked. Synthic exists because the answer layer got this big before anyone could tell you where they stood inside it.

Questions
Frequently asked questions
Everything worth knowing before your first audit. If it isn't here, write to us — a person answers.
Synthic is an AI search visibility platform. It measures how often AI answer engines — ChatGPT, Gemini, Claude, Perplexity and Grok — mention and cite your brand, gives you an AI Visibility Score, and produces a grounded plan to improve it.
Traditional SEO tools track where you rank on Google. Synthic tracks what AI engines actually say about you — measuring brand mentions in real, verbatim answers rather than modeled estimates, and labelling each mention as retrieval-verified or training-based.
Synthic runs live against ChatGPT (OpenAI), Gemini (Google), Claude (Anthropic), Perplexity and Grok (xAI) — the major answer engines your buyers ask.
Synthic fires your buyers' real questions at each live engine multiple times, stores every verbatim answer as evidence, and scores your mention rate, prominence, sentiment and share of voice against competitors — with a confidence reading, because AI answers vary run to run.
Founders, marketers, and SEO or GEO agencies who need to see and improve how their brand shows up in AI-generated answers — the new front page of the web.
