Buying a GEO tool by headline price gives different answers depending on whether you're a solo operator or an agency. We split the math both ways for the 5 mainstream GEO tools as of May 2026.
Single-brand entry pricing (USD / month)
| Tool | Entry tier | AI platforms covered | White-label | API/MCP | Agency-friendly |
|---|---|---|---|---|---|
| Arenza Free | $0 | 1 (ChatGPT) | No | No | No (1 brand, 10 prompts hard cap, 1 manual scan/week) |
| Arenza Pro | $9.99 | 1 (ChatGPT) | No | No | No (1 brand, 50 prompts; extras at $0.25/prompt-month) |
| Arenza Protect | $99 + usage | 10 (ChatGPT, Gemini, Perplexity) | Yes | Yes (MCP + REST) | Yes (multi-brand) |
| Arenza Enterprise | $999 + usage | 10 | Yes (full theming) | Yes | Yes + SSO + SOC 2 + dedicated CSM |
| Ahrefs AI Search Lite | $24 | 1 (ChatGPT only) | No | No | No (1 site, capped queries) |
| Ahrefs AI Search Pro | $49 | 1 (ChatGPT only) | No | No | No (1 site) |
| Peec.ai | $89 | 4 | No | No | No (1 brand) |
| Semrush AI Toolkit | $139+ (Semrush base) | 3 | No | No | No |
| Profound | $499+ | 4-5 | Enterprise tier | Enterprise tier | Limited |
Arenza Pro at $9.99/mo is the cheapest serious GEO tool on the market — ~58% cheaper than even Ahrefs AI Search Lite ($24/mo, capped queries), ~80% cheaper than Ahrefs AI Search Pro ($49/mo), and ~89% cheaper than Peec ($89/mo) for the same single-brand ChatGPT-tracking job. Plus it adds Arenza's Accuracy pillar (wrong-claim detection + fix suggestions) and Slack + Lark alerts that none of those competitors ship at the entry tier.
Agency math: 20 client brands
Pro is single-brand by design — for agencies the right Arenza tier is Protect at $99/mo + usage. Base includes 1,000 scans + 10 findings + 5 deployed fixes/mo across the entire workspace; overage runs $0.05/scan + $1/finding + $5/fix. Multi-brand workspace, all 3 AI platforms, white-label, MCP server, REST API are all included.
| Tool | Per-brand cost | 20 brands total | Notes |
|---|---|---|---|
| Arenza Protect | ~$4.95/mo + usage | $99/mo base + overage | Single workspace; overage scales with scan/finding/fix volume, not brand count |
| Peec.ai | $89/mo | $1780/mo | Per-site multiplier; no white-label |
| Ahrefs AI Search | $49/mo | $980/mo | Per-site multiplier; ChatGPT only; no white-label |
| Profound | ~$300/mo (negotiated) | ~$6000/mo | Enterprise contract; CSM-driven |
| Semrush AI Toolkit | bundled in Semrush | ~$$$/mo | Bundled; need full Semrush + add-on |
For an agency with 20 client brands, Arenza Protect at $99/mo base is 94% cheaper than Peec ($1780 → $99), 90% cheaper than Ahrefs AI Search ($980 → $99), and ~$5,900/mo cheaper than Profound (~$6,000 → $99). Add usage on top — for an agency running, say, 3,000 scans + 20 findings + 10 fixes a month across 20 brands, overage adds $135.00 (= $100.00 scans + $10 findings + $25 fixes), bringing the all-in to roughly $234.00/mo. Still under half of Profound's base.

Honest acknowledgments — where Arenza is NOT the cheapest
- Free trials: Peec and Profound run longer demo windows. Arenza Free is permanent but hard-capped at 1 manual scan/week, 10 prompts, ChatGPT only, single brand.
- Single-brand 1-LLM use case where you only care about ChatGPT: Arenza Pro at $9.99/mo wins on sticker, but if your team already pays for the full Ahrefs SERP toolkit, the bundled AI Search add-on may be incremental-cost-only and feel "free".
- Bundle pricing: if you already pay for Semrush, the Semrush AI Toolkit add-on is incremental cost only — looks cheap as a delta. Honest standalone cost of Semrush base is $$$/mo though.
