Best French and European GEO tools in 2026

Generative Engine Optimization, or GEO, is the practice of optimizing your presence in answers from generative AI engines like ChatGPT, Gemini, Perplexity, and Copilot. The category has exploded in two years, driven by the massive adoption of ChatGPT, which has reached 900 million weekly users since February 2026.

Most GEO platforms come from the United States. For a French or European company, three criteria often matter as much as the features, namely GDPR compliance, EU data residency, and real French-language support. This lens guides our selection, which is distinct from our general GEO tools comparison.

Before comparing brands, ask the right questions about your real constraints. A brilliant tool that is not GDPR-friendly can become a problem for a legal team or a large account.

The criteria to check first:

• Engine coverage, namely ChatGPT, Gemini, Perplexity, Copilot, Grok, and Google AI Mode.
• GDPR compliance and data location, ideally hosting within the European Union.
• French-language support, both for the tracked prompts and for the interface and onboarding.
• Analysis depth, either simple mention tracking or content audits and recommendations.
• SMB-friendly pricing, with a reasonable entry point and clear prompt quotas.

Hikoo is a French AI visibility platform, often described as the Google Search Console for AI. The starting point is simple. Your customers already ask ChatGPT, Gemini, or Perplexity which provider to pick, and most brands have no idea what those assistants say about them. Hikoo measures those answers every day, with a GDPR-friendly approach, so you can run AI answers as an acquisition channel like any other.

It all starts with your site. Once it's connected, Hikoo builds prompts from the questions your customers actually ask, then queries the engines daily. Depending on the plan, up to seven engines are tracked, namely ChatGPT, Gemini, Perplexity, Copilot, Claude, Grok, and Mistral's Le Chat, with Google AI Overviews and AI Mode as add-ons. For a European brand, having Mistral in the mix matters.

Four modules then cover the loop. Hikoo Analyzer audits, page by page, how AI engines read your site and, more to the point, what they can't find on it. Hikoo Spotlight tracks your mentions, citations, positions, and sentiment, market by market. Hikoo Battlemap compares your share of voice with your competitors' and shows which sources get them cited instead of you. Hikoo Elevate turns all of that into prioritized actions and article topics to win the spot back. The MCP server is included in every plan, so ChatGPT, Claude, or any MCP client can query your data without leaving the chat.

On pricing, a Free plan with no credit card gets you started with 10 prompts on ChatGPT. Lite costs EUR 69 a month for 30 prompts on ChatGPT and Gemini. Growth, at EUR 179, goes up to 80 prompts and adds Perplexity and Copilot. Scale, at EUR 389, opens all seven engines with 200 prompts and 20 tracked competitors. The 7-day trial needs no card, and the free audit gives you a first diagnosis in 30 seconds without creating an account.

Hikoo is mainly built for SMBs and agencies that want to tie their AI visibility to revenue without hiring a data team. Agencies get preferential pricing and a white-label kit to run several clients. More than 200 brands already use the platform.

Mentionable is a French tool that pitches itself as the GEO data layer for your AI. It tracks your brand every day across seven engines, ChatGPT, Claude, Perplexity, Gemini, Copilot, Google AI Mode, and Google AI Overview, then exposes that data (prompts, fan-out queries, citations, competitors, link-building opportunities) to any MCP-compatible agent.

Its first differentiator kicks in after measurement. On every tracked prompt where the engines answer without mentioning you, Mentionable writes a full markdown page with its JSON-LD, then checks whether the engines pick it up. The second is integration, with a public MCP server on the Pro and Agency plans that opens your tracking to Cursor, n8n, or any other MCP client. A built-in AI assistant in the dashboard, competitive analysis, and a weekly email summary round out the package.

On pricing, Growth starts at EUR 79 a month for 115 prompts and one project, Pro moves to EUR 149 for 231 prompts and three projects, and Agency at EUR 299 includes 5,000 credits, unlimited projects, white-label, and a one-shot GEO audit. All seven engines are included from the entry plan, and the 7-day trial needs no credit card.

Mentionable is built for consultants, founders, and in-house teams whose daily tool is already an AI agent, and who want it to work on real GEO data instead of making things up. The flip side, a team that stays in the dashboard only misses its main strength, and the on-page GEO audit is lighter than what audit-focused tools offer.

Mangools is a Slovak vendor, based in Bratislava, that has built SEO tools since 2014 with a reputation for being accessible and simple. Its AI Search Watcher module is a rank tracker dedicated to generative engines. It runs each prompt several times to smooth out the probabilistic nature of AI answers, then reports an average position, a visibility score, the citations you earn, and a side-by-side comparison with your competitors across ChatGPT, Gemini, Claude, Mistral, and Llama.

The free tier lets you track up to five brand prompts with a weekly email report, which makes it a low-risk entry point for an SMB that wants to test GEO before paying. A subscription to AI Search Watcher alone starts around 15 dollars per month on annual billing, and the full suite around 30 dollars, a clearly lower price point than the specialized platforms.

On the content side, Semji is a French vendor that added a GEO layer to its Content Intelligence platform. Rather than stopping at mention tracking, it ties your AI visibility to your editorial output. It analyzes visibility gaps between Google and generative engines, spots topics where your brand is not cited, and prioritizes the content to create or update to close those gaps. It is the most relevant option for a team that already runs an editorial calendar and wants to steer it toward AI answers.

For very small teams, Otterly AI is a deliberately simple Austrian monitoring tool. It tracks your brand presence and the links cited in ChatGPT, AI Overviews, Perplexity, and Microsoft Copilot answers, with Google AI Mode and Gemini as paid add-ons. Its appeal comes from fast onboarding and a $29 Lite plan, suited to a team starting out that wants to understand where it appears before investing in a full platform.

Peec AI is built in Germany and processes data inside the EU. It tracks six standard engines, ChatGPT, Google AI Mode, AI Overviews, Microsoft Copilot, Perplexity, and Gemini, with three models included per plan and each extra one billed at EUR 30, 70, or 140 depending on tier. The grid is public, EUR 85 to 425 a month, and seats stay unlimited. Its Source Identification traces where mentions come from, across review sites, social, and press, which makes it a good fit for a team that wants multi-country analytics. Claude sits outside the standard set, arriving with the agency and Enterprise offers.

Meteoria is French and hosts in Europe. Its catalogue holds seven engines, ChatGPT, AI Overviews, AI Mode, Gemini, Perplexity, Copilot, and Grok, but here is what to check before signing, every plan queries only 3 of your choice, Enterprise included, with the rest billed as extras. The analysis is then structured by tags, personas, locations, products, and purchase intent. Starter begins at EUR 75 for 25 daily prompts, Pro at EUR 175 for 100 prompts, Advanced at EUR 420 for 300 prompts with AI log analysis, and Enterprise from EUR 700. Seats, projects, and countries are unlimited on every plan.

The table below summarizes the European options we could verify. We prefer a short, honest list over a padded one. Each tool answers a different need, from multi-engine tracking to content optimization.

The right tool depends on your maturity and your constraints. Here is a quick read by the most common profiles.

• You want to steer your AI visibility end to end with a French vendor and a free audit, look at Hikoo first.
• Your team already works with an AI agent and wants to plug it into real GEO data, or even have the missing pages written, Mentionable is designed for that use.
• You want simple, affordable AI rank tracking to get started without a big budget, Mangools and its AI Search Watcher do the job.
• Your priority is producing content optimized for both Google and AI engines, Semji addresses that editorial use.
• You are a very small team that wants to start simply, a light monitoring tool like Otterly AI is enough to begin.
• Your legal team requires European hosting, favor a provider based in the European Union and GDPR-friendly from the start.

The GEO market is young and some claims deserve a careful look. Stay factual and test before you commit.

A few points to watch:

• Be wary of rankings that mix agencies and software, because these are two different categories.
• Check the real data location, because a European headquarters does not always guarantee hosting within the European Union.
• Do not rely on a single engine, because your audience may sit on ChatGPT as much as on Perplexity or Copilot.
• Ask for a trial or an audit before paying for an annual plan, to validate the relevance of the tracked prompts.

The GEO landscape is still dominated by US tools, but Europe is catching up fast. Hikoo flies the French flag with a complete, GDPR-friendly platform, Mentionable turns your GEO data into fuel for your AI agents, Meteoria plays the heavily segmented measurement card, and Peec AI brings multi-country analytics out of Germany. Mangools adds affordable AI rank tracking from Slovakia. Semji and light monitoring tools like Otterly AI round out the picture for more targeted needs.

If you are a French SMB, the simplest move is to start from a measured baseline. Run a free audit of your site to gauge your current visibility across AI engines, then pick the tool that matches your maturity and your data constraints. That is the best way to turn GEO into a measurable channel rather than a bet.
