TriRank is a mixed-to-good fit for AI search audit companies. Its $399 AEO / AI Visibility Audit is a one-time diagnostic with 5-7 business-day delivery, but platforms disagree on whether $399 is one-time or monthly and whether Google AI Overviews is covered.
Helium SEO is a qualified but contested fit for AI search audit buyers. Two of seven AI platforms named it, citing the AI Deep Dive Audit's 250+ prompt testing and citation analysis. However, no public pricing, contract terms, or independent validation exists for the audit.
Profound is a good fit for AI Search Audit Companies that need multi-engine visibility monitoring, citation tracking, competitor benchmarking, and prompt intelligence — but the fit is conditional, not clean.
Indexable AI is a good fit for enterprise buyers wanting a fast, human-led AI search audit. Its 14-Day AI Search Audit covers six AI platforms, competitor prompt and citation analysis, schema review, and a stack-ranked 30-day execution plan. Pricing is not published, and methodology claims are company-reported.
AI Search Engineers is a mixed-to-conditional fit for AI search audit buyers. Three of seven platforms named it, citing controlled prompt testing, citation inventories, and competitor displacement, but pricing is undisclosed and independent evidence is thin.
Peec AI is a good-to-strong fit for marketing teams wanting recurring AI visibility auditing rather than a one-time report. It tracks prompt-level visibility, benchmarks competitors, analyzes citations, and ranks next actions, but it does not execute content, authority, or technical fixes.
LLMAudit is a reasonable fit for U.S. marketing teams wanting lightweight AI visibility monitoring plus technical website-readiness audits across ChatGPT, Perplexity, Gemini, and Claude, if they can interpret results and execute fixes internally. Pricing and citation depth remain unclear.
optiseo is a weak-to-uncertain fit for AI Visibility Audit Services. Only 2 of 7 AI platforms named it, and its AI Visibility Dashboard is unlaunched with no confirmed pricing, features, or launch date.
Ahrefs Brand Radar is a qualified but contested fit for AI visibility audit services. It offers a large prompt index, competitor benchmarking, and citation reporting, but independent testing documents severe ChatGPT and Perplexity undercounting, and platform fit ratings split from strong to weak.
AthenaHQ is a good fit for marketing teams wanting recurring, cross-platform AI visibility auditing with prompt-level monitoring, competitor comparison, and citation analysis. Two of seven AI platforms named it, both at rank 2, but pricing and free-tier details conflict across sources.
ViAudit is a partially verified fit for AI visibility audit services. Two of seven platforms named it, both at rank 1. Its reported Agency Plan ($599/month) covers seven engines, competitor share of voice, citation tracking, and a 25-factor GEO audit, but pricing and outcomes lack independent validation.
