Pricing
PaidVisibilityStack starts at $800/month and is structured around two models. The self-serve agentic platform includes access to all three engines (Crawl Assurance, Topical Authority, Trust Signal), Prompt Analytics, the Communities module, and ongoing support from an AI Search Optimisation specialist. This is suitable for marketing teams that want to run GEO in-house with expert guidance. Guaranteed Outcomes plans are the managed service tier where VisibilityStack puts specific results in writing. Three outcome packages are available: AI Search Accuracy (fixing what AI gets wrong about your brand), AI Search Visibility (guaranteed to get your brand cited in AI answers within 120 days), and AI Search Leads (turning AI search demand into a measurable pipeline). These plans include the Demand Engineering System — a research-led methodology combining human experts with AI agents. All plans require a demo call via visibilitystack.ai/get-ai-search-action-plan. No free trial is available, but a free AI Search Action Plan audit can be requested before committing to a paid plan.
FreemiumFree: unlimited basic searches with Sonar, capped Pro Searches (~3-5/day), limited file uploads. Pro: $20/month ($16.67/month billed annually) — unlimited Pro Search, ~20 Deep Research queries/day, model switching across GPT, Claude, Gemini and Sonar, image/video generation, and Comet Plus included. Max: $200/month ($167/month billed annually) — unlimited Deep Research, Perplexity Computer with a large monthly credit pool, Model Council, and priority access to new models. Education Pro: $10/month for verified students via SheerID. Enterprise Pro: $40/seat/month; Enterprise Max: custom pricing (reported around $325/seat/month) with SSO, audit logs, and data-retention controls. The Comet browser is free for everyone. The Sonar API is billed separately, pay-as-you-go by tokens and search-context size.

VisibilityStack

VisibilityStack Pros & Cons

Pros

  • Three-engine architecture covers all layers AI systems evaluate — crawl access, topical authority, and trust signals — in one unified platform rather than 4-5 separate tools
  • Guaranteed Outcomes plans put results in writing — the only GEO platform offering a 120-day guarantee on AI search citation visibility
  • Published B2B case studies with specific pipeline numbers — SponsorCloud ($2.16M), Burrwood Veterinary (10x leads), Bryt Software ($847 → $284 CAC)
  • Tracks citations across ChatGPT, Perplexity, Google AI Overviews, and Copilot with prompt-level evidence — not just aggregate scores
  • Communities module monitors Reddit, YouTube, and Quora brand mentions — surfaces the third-party signals AI engines actually use for recommendations
  • Co-founder transparency — Pushkar Sinha published an honest comparison including VisibilityStack alongside 7 competitors with a bias disclosure, signalling integrity

Cons

  • Starts at $800/month — one of the most expensive tools in the GEO category, making it inaccessible for solo creators, small businesses, or teams under $5M ARR
  • Primarily built for B2B SaaS — explicitly less suited to e-commerce, consumer brands, or non-B2B verticals
  • No free trial — evaluation requires booking a demo and engaging the sales team
  • Requires commitment to either a managed service (Guaranteed Outcomes) or a self-serve platform with specialist support — not a simple SaaS sign-up
  • Newer platform (founded early 2025) — fewer third-party reviews and less independent validation than older SEO tools like Surfer SEO or Clearscope
  • The Demand Engineering System relies heavily on expert-plus-agent collaboration — teams wanting a purely self-serve tool may find the human-in-the-loop requirement adds friction
Perplexity

Perplexity Pros & Cons

Pros

  • Every answer includes transparent, checkable source citations
  • Genuinely useful free tier with no credit card required
  • Model-agnostic: choose the best AI model per query instead of being locked to one
  • Comet browser brings agentic search directly into everyday browsing, and it's free
  • Fast, cited answers for research-heavy and time-sensitive queries

Cons

  • Max tier is a steep 10x price jump from Pro ($20 to $200/month)
  • Citations occasionally don't fully match the underlying claim, requiring manual verification
  • Sonar API pricing is separate from subscriptions and can be harder to budget for
  • Not built for workflow/task automation like CRM updates or ticket handling
  • Weekly/monthly usage caps on some features can be a surprise for heavy users
