Catch the lies before your customers do.
Engines answer confidently, and sometimes they are confidently wrong about you — old pricing, a discontinued product, a competitor's feature attributed to yours. Synthic crawls your site for ground truth, asks each engine about you, and checks every claim against what you actually say.

01 — Ground truth
Your site is the source of truth. Literally.
At scan time Synthic crawls your pages and uses that content — and only that content — as the reference. Each claim an engine makes is a verdict against it: supported, contradicted, or not addressed. The correction for a contradicted claim is written from your own pages, so it is publishable as-is.
- Crawled live, never cached from a previous scan
- Claim-by-claim verdicts with the supporting passage
- Corrections drawn from your own content

engine claims
What each engine says when asked about you
| verdict | meaning |
|---|---|
| accurate | supported by what your site says |
| inaccurate | contradicted by your site — correction written from your own content |
| unverifiable | your site is silent — a page to write, or a claim to let stand |
severity: low · medium · high — high for wrong pricing, wrong product claims, brand confusion
02 — Triage
Fix the brand-damaging errors first.
Wrong pricing and mistaken identity are 'high'. A slightly stale team size is 'low'. Findings land in the Action Center ranked by severity, and alerts can fire the moment a new high-severity finding appears — to Slack or email.
- Severity: low · medium · high
- Alert rule: engine invents something about you

Every engine connected to your workspace. The free plan scans with Gemini; paid plans scan all five.
Can Synthic fix my site for me?
No — it writes the correction and you publish it. Synthic never writes into your site.
