Your customers no longer start all their searches on Google, and organic traffic trends show this across the board. An increasing share of purchasing decisions now involves ChatGPT, Gemini, Claude, and other tools like Perplexity, which people turn to for advice on which tool to choose, which service provider to contact, and so on.
If your brand doesn’t appear in the responses from these “LLM” response engines, you’re losing visibility with your prospects. That’s the whole point of GEO (Generative Engine Optimization), and a new category of software has just emerged to manage it. Mentionable is one such tool: a French platform, available starting at €79 per month, that’s garnering a lot of positive buzz in the French-speaking SEO community.
What is the real value of the data it provides? Is it useful even if you’re not an SEO expert? We put Mentionable to the test—here’s our full review.
Sommaire
Our Review of Mentionable: A Summary
| Perimeter | Score | Our opinion |
|---|---|---|
| Overall rating | 4,2 | Mentionable is a French GEO tool that tracks your visibility in the results of 8 AI search engines, identifies who the AI systems are citing instead of you, and tells you where to take action. It’s very comprehensive for its price, developed by a solo developer who’s iterating at a rapid pace. It’s an excellent entry point into GEO, provided you’re willing to accept that the product is still in its early stages. |
| Getting started | 4,3 | You start with an onboarding process that analyzes your site and automatically generates your follow-up prompts. You’ll get your first data in less than an hour. The real learning curve is that of GEO itself, not the tool. |
| Functional depth | 4.5 | The scope is impressive for a product that’s only been around for six months: multi-engine tracking, competitors, sources, fan-out queries, missed citations, page audits, quantified backlinks, Reddit signals, MCP… |
| Data Quality | 4,0 | Fan-out queries and missed citations are data you won’t find anywhere else at this price. On the other hand, the scan frequency depends on your credit budget, and AI traffic attribution remains an estimate (though all tools of this type face the same challenge). |
| Quality-price ratio | 4,6 | All 8 AI engines are included in every plan, with no additional charges per LLM. Compared to competitors who charge extra for each engine or reserve the most essential features for enterprise contracts, this is the key selling point. |
| Maturity | 3,7 | Launched in January 2026, run by a single person, with about 50 client brands. The product is evolving faster than its own showcase website. We love the speed—we’ll keep that in mind. |
Mentionable offers a 4-day free trial—no credit card required—on all of its plans. That’s enough time to run your first scans and find out what AI says (or doesn’t say) about your brand.
GEO in Two Minutes (and Why It Matters to You)
When you ask ChatGPT a question, it doesn’t just give you ten blue links. It breaks your question down into sub-queries (the so-called “fan-out queries”), queries traditional search engines, reads a handful of pages, and synthesizes an answer by citing three to five sources. No Page 2, no 8th position. Either you’re one of those sources, or you’re invisible.
GEO is about maximizing your chances of being cited and recommended in LLM responses. In practice, this involves structured content that AI systems can easily extract, as well as external validation: customer reviews, comparisons, industry publications, forum discussions, and so on. AI systems trust what third parties say about you at least as much as they trust your own website.
Important note: GEO does not replace SEO; it builds on it. AI systems use search engines to find their sources and analyze your pages based on their structure. A poorly optimized website will also be poorly cited. This is exactly where GEO tools like Mentionable come in: they measure your presence in AI-generated responses and then tell you where to focus your efforts first.
Who is behind Mentionable?
Mentionable was launched in mid-January 2026 by Alexandre Rastello, a French full-stack developer who is building the product on his own, without raising any funds. Six months later, the tool claims to have about 50 brand clients and more than 100,000 prompts executed each month.
This “solo builder” profile isn’t just a detail—it’s the product’s signature. The founder publicly documents everything on LinkedIn: his recurring revenue, his pivots, the features he cuts, and even his mistakes. The very concrete result for you: velocity. The pace is that of a product being built in real time, often in response to customer feedback posted the previous week.
The tool is supported by a small ecosystem: a free 74-lesson GEO training course (which was originally paid), a directory of manually verified agencies, and an open-source playbook for integrating Mentionable data into your workflows.
Buying a tool from a freelancer changes the dynamics at both ends of the experience. Support comes directly from the founder, and a feature request can be delivered in just a few days. On the other hand, the tool’s long-term viability depends on a single person, and the roadmap can shift quickly. This isn’t a deal-breaker in our view, given the price and the lack of a long-term commitment, but keep it in mind, especially if you plan to use it as the basis for an agency offering.
Getting Started on Mentionable: A Carefully Crafted Onboarding Experience
Setup begins with a single piece of information: the URL of your homepage. Mentionable analyzes your site, identifies your brand name, any aliases you may have, and a description of your business. Everything is editable, and we strongly recommend that you review this description: it sets the tone for everything that follows.
You then specify the target country and language, along with any additional context if needed (such as a sector-specific focus). The tool then generates about 15 purchase intent prompts tailored to your market.
It’s not about definitions, but the actual phrases a buyer types in. You sort through the suggestions, add your own, and then select which models to use from the eight available (ChatGPT, Claude, Perplexity, Gemini, Grok, Copilot, Google AI Mode, and Google AI Overviews).
The first scan starts right away, and the first results come in within minutes. It takes less than an hour from the time you create your account until your dashboard starts providing you with very concrete insights into your site’s visibility in LLMs.
Your prompts are the foundation for everything else. Take the time to refine them from the start, focusing on phrasing that reflects purchase intent within your core market. A sloppy setup on day 1 means a month of mediocre data.
What Mentionable Teaches You (and What You Couldn’t Have Guessed)
Rather than a random list, here’s what the tool offers at each stage of your GEO work: measuring, understanding, and taking action.
1 – Measure: Your Share of Voice Compared to Competitors
The dashboard tracks the trends in your mentions scan by scan, the search queries where you rank highly, and your share of voice in the market.
Here’s an interesting detail: you don’t have to list your competitors—Mentionable detects them directly in the AI’s responses, and you can either confirm or dismiss them. The prompt-by-prompt breakdown shows where you’re leading and where you’re falling behind.
In terms of traffic, a Google Analytics 4 integration isolates sessions originating from AI and tracks their share of your user acquisition. This is useful for objectively assessing this channel, with one caveat: when AI does not pass a referrer, attribution is based on estimates. Consider these figures as rough estimates.
2 – Understanding: Sources, Fan-Out Queries, and Missed Citations
The “Sources” section lists the domains that AI systems cite in response to your prompts, along with their citation patterns and the specific pages used—whether those pages are displayed explicitly in the response or simply accessed in the background. This is your roadmap to the media that matter: if a comparison site or review platform consistently influences responses in your market, you’ll know where your brand needs to appear. Managing your customer reviews also becomes a full-fledged GEO strategy in its own right.
Fan-out queries take it a step further. These are the subqueries that the AI runs behind the scenes before providing an answer. Mentionable collects and categorizes them. You’ll discover the actual angles from which AI approaches your topic (and these are all content ideas that no traditional keyword tool will give you).
And then there are the missed citations—a truly unique feature. The tool identifies responses based on your own pages… without mentioning your brand. Each instance identified links to an audit of the relevant page to help you understand what’s holding things up.
Fan-out queries and missed citations alone make the tool worth it. This is data that’s impossible to reconstruct by hand—even if you spent your days on ChatGPT—and it turns a tracking spreadsheet into an action plan. That’s where Mentionable goes beyond being just a “thermometer.”
3 – Take Action: Page Audits, Quantified Backlinks, and Reddit Signals
The page audit analyzes a URL the way an AI crawler would and generates a list of fixes prioritized by impact: heading structure, content extractability, structured data, and freshness.
The backlinks module matches your opportunities with the prices listed on link marketplaces: you can see which domains AI tools are already citing in your market and how much it would cost to appear on them. This is useful if you have a budget to invest in link building.
A quick note on Reddit signals—another module offered by Mentionable. It’s well known that AI loves Reddit, and Mentionable identifies discussions relevant to your brand, ranks them by potential, and even suggests draft responses in three different tones.
AI-generated Reddit replies that mention your brand—when done without subtlety—have a name: astroturfing. Communities quickly spot it and penalize it for the long term. Use these drafts as a starting point, respond only when you have a genuine contribution to make, and be true to who you are.
The final component of the system is the action log. Every GEO action you take (a post, a link-building campaign) is logged and appears as a marker on your visibility graph. It’s a simple yet valuable tool for linking your efforts to their results.
MCP: Your GEO data directly in Claude or ChatGPT
This is Mentionable’s most innovative offering and a rarity in the category to date: an MCP (Model Context Protocol) server that exposes all your GEO data to your AI tools. In practice, you can query your citations, sources, fan-out queries, or visibility by persona using natural language, directly from Claude, ChatGPT, or Cursor. Mentionable’s official playbook provides ready-to-adapt workflows, from audits to client reporting.
The founder is also steering the company toward a strategic shift: turning Mentionable into a geospatial data infrastructure rather than just another dashboard. If your teams are already working with AI agents, this is a real differentiator. Integration is available starting with the Pro plan.
The Agency Division: GEO’s Sales Machine
This is the least prominent section of the website, yet it is very interesting. Mentionable has built a comprehensive GEO audit production pipeline for agencies and consultants.
The one-time audit generates a report in just a few minutes that’s ready to be delivered to a client: competitive ranking, prompt heatmap, key market sources, backlink opportunities, a written analysis, and a content plan. The audit can be run again each month to track progress in your reports.
Bulk mode takes things to a whole new level: up to 500 audits run simultaneously on the same set of prompts, with the cost spread across an entire niche. Here’s a typical scenario: you compile a list of websites in a specific segment, launch the audits, export the results to your lead generation tool, and each prospect receives a personalized audit addressed to them, complete with your call to action (CTA). The GEO audit goes from being a deliverable to a closing tool.
The entire platform is fully white-labeled for agencies: your logo, your colors, your name, your support email address, and even your own domain name. Mentionable is completely hidden.
How much does Mentionable cost?
Mentionable offers three plans, all excluding tax, with an approximate 17% discount for an annual commitment.
| Plan | Growth | Pro | Agency |
|---|---|---|---|
| Monthly price | €79 | €149 | 299 € |
| Annual subscription | €66/month | 124 €/month | 249 €/month |
| Projects | 1 | 3 | Unlimited client projects |
| Tracked prompts | Up to 115 | Up to 231 | Up to 385 |
| Monthly scan credits | 1,500 | 3,000 | 5,000 + usage at €0.02 per scan |
| AI Engines | The 8 | The 8 | The 8 |
| MCP Integration | No | Yes | Yes |
| White-label and client audits | No | No | Yes |
| For whom | A brand just starting its tracking | Multiple brands or projects running simultaneously | Agencies and consultants |
Regarding the logic behind the credits:
- One credit equals one scan: a prompt queried on a search engine for a specific persona. With 1,500 credits, for example, you can run 45 prompts across the 8 search engines four times a month. Your credit allowance therefore determines the number of prompts, the search engines covered, and the frequency of use.
- Page audits and Reddit enhancements draw from the same pool (expect to use about 100 credits per page audit as of this writing).
- On Agency, once you exceed 5,000 credits, the billing model switches to pay-as-you-go with a monthly limit that you set.
Each plan includes a 4-day free trial with no credit card required, and monthly subscriptions can be canceled at any time. There is no permanent free plan, but three free tools that require no registration let you get a first impression: an AI visibility check, a page GEO audit, and an llms.txt generator.
Four days of trial is short for a tool whose value is revealed over time. Prepare your list of prompts before creating the account, configure everything on the first day, and push the scan frequency to the maximum. This will give you three real days of comparable data to judge for yourself.
. You get a free 4-day trial—no credit card required. It’s a smart move before committing to a subscription.
Our verdict: Who is Mentionable designed for?
Mentionable is right for you if:
- Do you run an SME or a consulting firm and want to know—with data to back it up—whether AI can help you succeed without an enterprise-level budget?
- Your marketing team already has a solid grasp of SEO and is looking to add a geographic layer using a robust management tool.
- If you’re an agency or a consultant looking to launch a GEO offering, the white-label audit and bulk mode are a powerful sales tool.
- Your teams are already working with Claude or AI agents and want to integrate GEO data into their workflows via the MCP.
Skip it if :
- You are a large enterprise with strict compliance and integration requirements: documented APIs, certifications, and SLAs.
- Are you looking for a tool that does the work for you? Mentionable tells you what to fix and where to focus, but you still have to create the content and build backlinks yourself.
- You have to keep track of dozens of markets and languages at the same time.
Final rating: 4.2/5. In our view, Mentionable is the best entry point into GEO for the French-speaking market. The data is unique, the scope of functionality is impressive for the price, and the agency component opens up real business opportunities. The main concern remains the youth of the product and the organization behind it. At this price and with no commitment, giving it a try is well worth it.
Mentionable is the obvious choice for getting started with GEO without an enterprise budget: tracking of 8 AI engines, missed citations, white-label audits, and MCP, starting at €79 per month. Take advantage of the 4-day free trial to see for yourself.
