Tools to measure your clients' AI visibility: a comparison for agencies
Checking by hand whether a client appears in ChatGPT works exactly once: the week you prepare the meeting. By the third week, with five clients and four AIs, you've turned someone on your team into a screenshot-making machine (the maths of what that costs, here). At some point a tool becomes necessary, and the market has filled up with options priced from 29 to over 2,000 dollars a month.
The problem with almost every comparison is that it's written for brands measuring themselves. An agency buys with three other criteria in front of it: cost per client (because the tool cost comes out of your margin), multi-client management (separate workspaces, not everything mixed in one dashboard) and language and market (your clients sell in Spanish; the AIs answer differently in Spanish). This comparison uses those criteria. Prices verified in June 2026; in this market they change fast, so check before you sign.
The tools, one by one
PromptWatch — the most complete product, built in dollars and in English
The European reference in the sector (Amsterdam, 2025). Prices: Essential 99 $/month (50 prompts, 1 site, 1 user), Professional 249 $/month (150 prompts, 2 sites) and Business 579 $/month (350 prompts, 5 sites, with a prior demo). Its strength is depth: real logs of the AI crawlers via CDN, attribution of traffic arriving from AIs, analysis of which sources each engine cites, and agency-specific features such as a client portal.
Through an agency lens: to handle 5 clients you need the Business plan, which works out to roughly 116 $ per site a month, and the user caps (1/2/5 by plan) pinch in a team. Reviews note a learning curve and a dense interface, and the whole product is in English and dollars, with no focus on the Spanish market. A serious tool if you handle clients selling in English-speaking markets. Detailed comparison: Surfeo vs PromptWatch.
Otterly.AI — the cheap entry point that climbs in price fast
Lite 29 $/month (15 prompts), Standard 189 $/month (100 prompts), Premium 489 $/month (400 prompts), with Gemini/AI Mode as an add-on from 9 to 149 $/month and a 15% annual discount. It includes GEO audits of URLs, a useful extra.
Through an agency lens: the Lite plan is perfect for testing the concept with one client, but 15 prompts fall short for serious tracking, and splitting the Standard's 100 across several clients leaves each one with a minimal sample. It isn't designed as a multi-client tool with separate workspaces. Detailed comparison: Surfeo vs Otterly.
Peec AI — for SEO teams, with opaque pricing
Berlin-based, geared towards SEO teams. Its site publishes no figures; 2026 sources put the Starter at around 89 €/month (25 prompts) and the Pro at around 199 €/month. A solid product for analysis, but the pricing opacity makes budgeting a productised service harder, and 25 prompts for ~89 € is one of the highest costs per prompt on the list. Detailed comparison: Surfeo vs Peec AI.
Profound — enterprise, out of the league for SME agencies
No public pricing and no self-serve sign-up; third parties report anywhere from around 399-499 $/month up to 2,000-5,000+ $/month at enterprise level. It's the option for large American brands with a platform budget. If your agency handles multinationals, ask for the demo; if it handles SMEs, the cost per client doesn't add up even if you cheat.
Semrush AI Toolkit and Ahrefs Brand Radar — the suite add-ons
If you already pay for an SEO suite, its AI module is the path of least friction. Semrush AI Toolkit: 99 $/month per domain, on top of a Pro plan at 139.95 $/month (or Semrush One from 199 $/month). Ahrefs Brand Radar: an add-on at 398 $/month (selected platforms) or 699 $/month (all of them), on top of a base plan from 119 €/month.
Through an agency lens, the lethal detail is Semrush's "per domain": 10 clients is 990 $/month for the add-on alone, plus the suite. And Ahrefs doesn't drop below hundreds of dollars before the first client. These are modules designed for a brand to monitor itself, not for portfolios. Detailed comparison: Surfeo vs Semrush.
SE Ranking — the most reasonable of the suite add-ons
AI add-on at 79 €/month (63.20 € annually) on top of its Core plan at 87.20-109 €/month: around 150-188 €/month in total. If you already use SE Ranking for your portfolio's SEO, it's a sensible extension. The limitation is the same as all add-ons: AI visibility is a module bolted onto an SEO suite, not a multi-client product designed to deliver each client their own.
Surfeo — built for Spanish agencies with an SME portfolio
This is our house, so judge with that in mind; the numbers are public. The agency plan: 20 €/month for the base account plus 35 €/month per client on the Starter tier (40 prompts, ChatGPT + Gemini + Perplexity, 6 pieces of content/month, analysis of the main competitor, weekly tracking) or 79 €/month on the Growth tier (75 prompts, 4 AIs including Claude, 16 pieces of content/month). Up to 10 clients, each in its own separate workspace and with the full product -the same one a direct client would buy at 39/99 € retail-, PDF reports for your reporting, extra team seats at 19 €/month and 3 pitch workspaces to audit potential clients before signing. All in Spanish and built on Spanish market data (study of 9,865 SMEs).
What we're not: if you need CDN-level crawler logs or you handle enterprise brands in English-speaking markets, PromptWatch or Profound will give you more depth.
The table through an agency lens
| Tool | From | 10 clients (approx.) | Real multi-client? | Spanish |
|---|---|---|---|---|
| PromptWatch | 99 $/month | >1,158 $/month (2× Business) | Partial (sites by plan) | No |
| Otterly.AI | 29 $/month | 489 $+ (shared prompts) | No | Partial |
| Peec AI | ~89 €/month | No public price | Partial | No |
| Profound | ~399 $+/month | Thousands of $/month | Enterprise | No |
| Semrush AI Toolkit | 99 $/domain + suite | ~1,130 $/month | Per domain | Partial |
| Ahrefs Brand Radar | 398 $/month + suite | 398-699 $ + base | Limited | Partial |
| SE Ranking | ~150 €/month total | On request | Limited | Yes |
| Surfeo Agency | 55 €/month (base + 1 client) | 370-810 €/month | Yes (10 workspaces) | Yes |
The maths that matter: with 10 clients on Surfeo you pay between 370 € (all Starter) and 810 €/month (all Growth) — 37 to 81 € per client. If you charge for the service in the usual Spanish range of 300-900 €/month per client (the ranges, here), the tool eats less than 15% of the revenue. With suite add-ons or dollar-priced plans, that percentage shoots up or there's simply no multi-client structure to spread across.

Frequently asked questions
Can I start without a tool, by hand?
For a client's first audit, yes, and it's actually wise: you understand the work before automating it. For the weekly tracking of a portfolio, no: AI answers change constantly and a one-off manual measurement isn't comparable month to month.
What happens if a tool changes its prices?
It will: this market is two years old and prices move every quarter. We verified this data in June 2026; treat any comparison (this one included) as a snapshot, not a contract, and confirm on the provider's site before budgeting your service.
Do I need the tool to cover all 4 AIs?
For SME clients, ChatGPT, Gemini and Perplexity cover the vast majority of real usage in Spain. The fourth (Claude) adds value mainly in B2B and technical profiles. That's why a cheaper 3-AI tier makes sense for the local client and the full one for whoever can justify it.
Does the tool do the service for me?
No, and be suspicious of any that promises it. The tool measures, alerts and generates drafts; the judgement -which sources to fix, what content to publish, how to tell the client- is your service and it's what you're paid for. The tool replaces the screenshots, not your team.
The best way to evaluate any of these tools is with a real case on the table. Take the free AI visibility test with a client from your portfolio and, if you want to see how your account would look on the agency plan, the numbers are on the pricing page.
