Scrunch focuses on connecting AI visibility to real traffic and revenue, plus producing machine-readable content for AI agents. Bidvix focuses on diagnosing a domain and handing you a fix list. Both care about measurement, but they start from different ends of the funnel.

Where Scrunch is stronger
AI referral attribution as a product. Scrunch treats AI-driven traffic and revenue as the headline metric, with dedicated instrumentation. If your board asks "what revenue did AI bring us", that framing is its home turf.
Agent-experience tooling. Scrunch invests in making brand content readable and actionable for AI agents, beyond plain text summaries.
Brand-side workflow. Its positioning suits marketing teams that want a managed, attribution-oriented view.
Where Bidvix is stronger
Diagnosis depth. Bidvix runs a full technical audit alongside visibility measurement: crawlability, titles, meta descriptions, heading order, thin content, duplicate metadata, broken internal links, AI crawler access and llms.txt. Scrunch is not a site auditor.
Affordability and API. Free diagnosis, a low-cost Pro plan, and a credit-based API make Bidvix practical for a single exporter or an agency running checks programmatically.
Claim accuracy checks. Bidvix cross-checks factual statements AI makes about your brand against your own published facts. This catches "AI says we charge X" errors that pure attribution cannot see.
Verifiable sampling. Every sampled answer is inspectable, so mention and citation numbers can be traced to the source response.
Complementary, not identical
It is entirely reasonable to use both: Bidvix to find and fix what makes you invisible, Scrunch to quantify the revenue that results. The mistake is buying an attribution tool when the underlying problem is that your site is not readable by AI crawlers — attribution will simply report zero.
A practical test
Connect your analytics and ask each vendor two questions:
- How many sessions and how much revenue came from AI platforms in the last 30 days?
- Which pages are blocked from AI crawlers, and which lack an
llms.txt?
A pure attribution tool answers (1) well. A diagnostic tool answers (2) well. If you cannot answer (2), attribution numbers will stay flat no matter what you spend.
