Quick answer
MentionLab.ai (the "Blue" agent, published by KOMTOP SARL, a French company verifiable in the public register; nothing to do with mentionlab.io or .co) overhauled its offer on 17 July 2026, during the day: a single Blue Business plan at €89 excl. VAT per month per site, €129 shown struck through, for 30 articles, with auto-publishing, citation tracking advertised in ChatGPT and Perplexity and, new that day, a "backlink exchange network." The old Starter plan at €29 excl. VAT for 5 articles disappeared from the public pricing. The tool suits a French-speaking SME that wants a high monthly volume in French, at a contained price, from an identifiable vendor. It suits you poorly if you require an auditable AI tracking method, a documented link network (the terms from the same day don't govern it), or substantial independent feedback. An on-the-record analysis, recaptured 17 July 2026 at end of day, with no hands-on test; I run a competitor, SEOryon, so judge my facts on their sources.
Key takeaways
- The 17 July 2026 overhaul: a single plan at €89 excl. VAT/month (struck through: €129), 30 articles, Starter withdrawn from the public pricing.
- The terms, updated the same day, confirm €89 excl. VAT and 30 articles: marketing price and contractual price are aligned.
- The "backlink exchange network" is listed in the pricing but absent from the terms: credits, preview, and attributes not documented.
- A 5 day trial with automatic conversion; trial articles count against the first month's quota; no B2B refund afterward.
- Each additional language costs €30 excl. VAT/month; each additional site, a separate subscription.
Method for this review
Public pages captured 17 July 2026, with a second capture at end of day after the vendor's revision: French and English pricing, terms of sale, product page, case studies, company register. No account opened. "Not publicly documented" means not findable in those sources. The cluster's full method: the comparison of the six tools.
What MentionLab genuinely does well
First, identity: it's one of the few players in the panel that's fully traceable. KOMTOP SARL, SIREN 909 980 765, active, registered in 2022 in Lorient, founded by Matthieu Carcenac and Baptiste Lacroix, backed by an SEO agency started in 2020 per the about page. For a B2B purchase, that traceability has value.
Next, the product promise is coherent: Blue analyzes real volumes and the pages already ranking in the top 10 to calibrate length and structure, checks the site's existing content to avoid cannibalization, advertises figures checked at the source and a 20 point review, publishes to WordPress, Framer, Webflow, Shopify, PrestaShop, or a webhook, and exports in Markdown or HTML. The new quota of 30 articles at €89 excl. VAT gives an apparent cost of 89 ÷ 30 = €2.97 excl. VAT per article, the lowest in the panel in euros; capacity, not quality, as always.
Finally, the day's contractual alignment deserves noting: the terms rewritten on 17 July 2026 state in black and white €89 excl. VAT per month per site for 30 articles. A marketing price confirmed by the contract on the same day is better than this category's average.

| Item | Value captured | Source and date |
|---|---|---|
| Blue Business | €89 excl. VAT/month per site (struck through: €129) | FR pricing · 17/07/2026, end of day |
| Quota | 30 SEO and LLM articles/month; unused quota lost | Terms · 17/07/2026 |
| Additional language | €30 excl. VAT/month per language | Terms · 17/07/2026 |
| Trial | 5 days, free, automatic conversion unless cancelled | FR pricing · 17/07/2026 |
| Former Starter | €29 excl. VAT/5 articles: withdrawn from the public pricing on 17/07/2026 | recapture finding |
First year: 89 × 12 = €1,068 excl. VAT for one site and one language; add 30 × 12 = €360 excl. VAT per additional language, and a full subscription per additional site. VAT is added at the applicable rate. The struck-through €129 displays no promotion end date: treat €89 as today's price, not as a given.
The trial in practice
Five days, sign-up via Google or email then Stripe. Two contractual rules to know before starting: the subscription starts automatically at the end of the trial unless cancelled, and the articles produced during the trial are deducted from the first paid month, they aren't added to it. Cancellation is done from the dashboard and takes effect at the end of the period. No refund afterward, not even pro rata: the contract is explicitly reserved for businesses, with no consumer right of withdrawal.
AI citation tracking: advertised, not auditable
The plan lists "AI citation tracking: ChatGPT and Perplexity." What's publicly missing: the number of questions tracked, how they're selected, the frequency, the repeats in the face of non-deterministic answers, the exact definition of a citation (link, domain, or a simple mention), and the raw export. Some vendor pages also mention Claude, inconsistently; I only record ChatGPT and Perplexity, which appear in the pricing. Treat this module as a useful bundled signal, not as an auditable measuring instrument, and ask the questions from my grid on choosing an AI citation tracker during the trial; to build your own indicators, the guide to measuring AI visibility gives the protocol.
The new backlink network: the line to document first
This is the overhaul's most significant change: "Backlink exchange network" now appears in the plan's features. Yet the terms updated the same day say nothing about it: no credit system described, no right of preview, no attributes, no exit rules. A link exchange commits your pages (you host outbound links) and your inbound link profile: before activating anything, get in writing the exact mechanics, the right of refusal placement by placement, and the attributes used. Google lists excessive exchanges intended to manipulate rankings among its examples of link spam; without predicting a penalty, apply the diligence checklist for link platforms to this network as to any other.
Case studies: eight files, one origin worth knowing
MentionLab publishes eight case studies with Search Console screenshots, including Aquaclim Service (7,330 clicks, 419,000 impressions, 1.75% CTR over three months), Vision Plus (498 clicks, 15,600 impressions, 3.19% CTR, an AI citation claimed), ClemCo Digital (6,390 clicks over twelve months), Eduniversal (28,100 clicks, 5.05 million impressions), and Best Masters (28,200 clicks). Two limits to keep in mind: these are figures published by the vendor, with no audited baseline and no separation from other actions; and the about page ties those results to the agency method guiding Blue, not necessarily to eight standalone deployments of the SaaS. They prove documented agency expertise, not a guaranteed result of the software.
On independent reviews, the 17 July finding still holds: no G2, Capterra, or Trustpilot corpus attributable to mentionlab.ai specifically. It's a young product; the absence of feedback isn't a hidden defect, it's a purchasing data point.
Cancellation, refund, ownership
| Topic | What the terms of 17/07/2026 provide |
|---|---|
| Cancellation | At any time from the dashboard; effective at the end of the paid period |
| Refund | None once started, not even pro rata, outside mandatory law; a B2B contract |
| Content ownership | To the client after payment; the client remains responsible for review and publishing |
| Quota | Not carried over from one month to the next |
| Guarantees | A best efforts obligation; no ranking or traffic guaranteed; liability capped |
How SEOryon differs
Two French products, two philosophies. MentionLab has just added a link exchange network; SEOryon won't have one: the backlinks module informs (domain rating, referring domains, broken links), it places nothing, and it's now the only one of the six tools in the comparison in that position. On AI measurement, the SEOryon audit queries ChatGPT, Claude, Gemini, and Perplexity with real buyer questions you can view and edit, where MentionLab advertises ChatGPT and Perplexity with no published method. On production, SEOryon has you approve each topic and inject your expertise before the writing, then verifies facts and sources before publishing (dead links dropped, competitors never cited). On the other side, be honest about the numbers: since the overhaul, MentionLab offers 30 articles at €89 excl. VAT while SEOryon Growth produces 30 for €149; if cost per published article is your first criterion, MentionLab wins that column. SEOryon's entry plan is €39/month for 10 articles, a 3 day trial with a card, €0 charged, 3 real articles published on your site: cancel before day 3 and you pay nothing. .
Who it fits, who it doesn't
A good fit: a French-speaking SME wanting 30 articles a month in French for under €100 excl. VAT, from a legally identifiable vendor, with a first level of AI tracking. To avoid without written answers: teams that require an auditable tracking methodology, brands that refuse any link exchange or want its mechanics documented at minimum, multi-site or multilingual organizations that should first price €89 per site plus €30 per language.
FAQ
What did the 17 July 2026 overhaul change?
Three things, on the same day: the single plan moves to €89 excl. VAT/month for 30 articles (the offer was €79 excl. VAT for 20 that same morning), the €29 excl. VAT Starter entry point disappears from the public pricing, and a backlink exchange network appears in the features. The terms were updated immediately after and confirm the new price.
Does the trial require a card and renew by itself?
Sign-up goes through Stripe and the subscription starts automatically after the 5 days unless cancelled; the articles generated during the trial are deducted from the first month. Cancel from the dashboard before the trial ends if you're not continuing.
How much does an additional language cost?
€30 excl. VAT per month per language, provided for in the terms. A site in three languages therefore comes to 89 + 30 + 30 = €149 excl. VAT per month.
How are ChatGPT and Perplexity measured?
The vendor publishes neither a question panel, nor a frequency, nor repeats, nor a definition of a citation. Ask for those during the trial; without them, compare exported observations rather than scores, as explained in measuring AI visibility.
Do the case studies prove the software's results?
They document real Search Console trajectories published by the vendor, drawn from the agency method that inspired Blue. With no audited baseline and no separation from other actions, they prove expertise, not a reproducible causality of the SaaS alone.
