Generative Engine Optimization (GEO) tools measure how AI assistants like ChatGPT, Gemini, Claude, and Perplexity describe a brand to its users. As of May 2026 there are five mainstream tools competing for SEO/GEO agencies and brand teams.
This page compares them by listed monthly price, AI assistant coverage, agency-friendliness (white-label, bulk import, MCP), and what you actually get for the money. All prices are USD list, billed monthly, as of 2026-05-03.

Why Arenza is the cheapest serious GEO tool
Two angles, depending on the buyer.
Single-brand operators (in-house marketing, founders, indie SEOs)
Arenza Pro at $9.99/mo is roughly ~80% cheaper than Ahrefs AI Search ($49/mo) and ~89% cheaper than Peec ($89/mo) for the same job — weekly ChatGPT tracking on one brand with accuracy + fix suggestions, Slack + Lark alerts, 50 prompts (extras at $0.25/prompt-month).
SEO/GEO agencies (10–200 client brands)
Pro is single-brand by design — the agency tier is Arenza Protect at $99/mo + usage. Multi-brand workspace, all 3 AI platforms, white-label, REST API, MCP server, and 1,000 scans + 10 findings + 5 deployed fixes/mo included. Overage is $0.05/scan + $1/finding + $5/fix.
- Arenza Protect: $99/mo base + usage. 20 client brands all live in one workspace; white-label is per-brand.
- Ahrefs AI Search: $49/mo per site. 20 client brands → $980/mo total. No white-label.
- Profound: starts at $499/mo with per-brand seat charges; agency rate cards typically land at $300+/brand.
The architecture is what makes Arenza cheaper: a single tenant holds many brands, probes batch through one router across all 10 LLM endpoints, and white-label is a row-level setting rather than an enterprise upsell.
What you give up at this price
Honesty up front — Arenza is a 2026 entrant. You are not getting Ahrefs' 12-year-old backlink graph, and you're not getting Profound's enterprise-grade SLA + dedicated CSM. What you get is the GEO half of the job — measurement plus accuracy plus fix prescriptions — at agency-scale pricing.
When to pick something else
- You need traditional Google SERP rank tracking on top of AI visibility → Ahrefs / Semrush bundles win on breadth.
- You need a hands-on consulting relationship with the vendor → Profound has a managed-service motion.
- You only track one brand and care about ChatGPT only → Arenza Pro at $9.99/mo undercuts Ahrefs AI Search ($49/mo) by ~80%; if you already pay for the Ahrefs SERP toolkit and want it bundled, stay on Ahrefs.
