// The stakes
Your buyers already moved. Your visibility hasn't.
Every glowing point is a hub where buyers now ask an AI before they ask a search box. The question is whether the answer names you.

Search had ten blue links. The answer has one.
AI engines don't list options — they name a winner. Miss the answer and a competitor is named in your place, on every prompt.

Teams stopped guessing what the models say
“We were invisible in ChatGPT for our own category. Six weeks after shipping Synthic's schema and llms.txt, we're the first brand it names — and we can prove it with the raw answers.”
Priya Nadecki
VP Marketing · Northwind Labs
“The hallucination scan caught pricing Grok had flat-out invented about us. Fixed the same day with the generated schema.”
Devin Alarcon
Founder · Cobalt
“Finally a GEO tool that shows the raw answer behind every number. No black box, no vanity score — my board actually trusts it.”

What Synthic is, in plain terms
Written answer-first on purpose — the same structure Synthic engineers into your site so an AI engine can quote it cleanly.
What is Synthic?
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.
How is Synthic different from traditional SEO tools?
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.
Which AI engines does Synthic track?
Synthic runs live against ChatGPT (OpenAI), Gemini (Google), Claude (Anthropic), Perplexity and Grok (xAI) — the major answer engines your buyers ask.
How does Synthic measure my visibility?
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.
Who is Synthic for?
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.
Is my first audit really free?
Yes. You can run your first AI visibility audit free, with no credit card, and see exactly how the engines describe your brand today before deciding to go further.
The answer is being written right now.
