Key takeaways
- Mentionable's biggest selling point is price and engine coverage (all 7 engines, no add-on fees), but it scans roughly twice a week by default and does nothing to help you write or publish content once you spot a gap.
- If you want a platform that also fixes the problem it finds, Promptwatch and AthenaHQ are the two real "full-stack GEO" options, with Promptwatch adding crawler logs and Reddit/YouTube citation tracking that neither Mentionable nor AthenaHQ has.
- If you're already paying for Semrush, its AI Visibility Toolkit is a reasonable bolt-on, but reviewers have caught it generating nonsensical recommendations (one review literally shows it claiming 2 x 5 = 12).
- Otterly.AI and Peec AI are the closest in spirit to Mentionable: cheap, monitoring-focused, daily scans, but both gate some engines behind paid add-ons, which Mentionable doesn't do.
- Profound and Rankscale sit at opposite ends of the enterprise spectrum: Profound has quietly dropped its self-serve tiers in favor of a trial-then-sales-demo model, while Rankscale is one of the cheapest credit-based options if you don't need Claude very often.
Why people look past Mentionable
Mentionable does one thing well: it tracks all 7 major AI engines (ChatGPT, Claude, Gemini, Perplexity, Copilot, Google AI Mode, Google AI Overview) for a flat fee, with no per-engine upsell. That's genuinely rare. Otterly and Peec both gate Claude or Gemini behind add-ons, and Mentionable doesn't.
But it's a one-person product. Built and run solo by a French developer, launched in January 2026, no outside funding. That's not automatically bad, but it shows up in two places. First, the scan cadence on paid plans defaults to around twice a week rather than daily, which matters if you're trying to catch a citation drop the morning after it happens. Second, Mentionable is purely a measurement layer: no content drafting, no content calendar, no CMS publishing. It tells you what's missing and leaves the writing to you. For a lot of small teams that's fine. For teams that want the gap closed automatically, it's the reason to look elsewhere.
Promptwatch
Promptwatch is the platform to look at if you want more than a scoreboard. It tracks ChatGPT, Claude, Gemini, Perplexity, Grok, Copilot, DeepSeek, Mistral, Meta Llama, Google AI Overviews and Google AI Mode, and it backs that up with a dataset Mentionable simply can't match: over 4.5 billion citations, clicks and prompts analyzed, 1,840+ paying customers including Duolingo, Yelp and Typeform, 4.7/5 on G2.
What actually separates it from Mentionable is the "why" and the "then what." Promptwatch's Agent Analytics shows real AI crawler logs, ChatGPTBot, ClaudeBot, PerplexityBot and 400+ others, so you can see whether a bot even read the page before deciding why it isn't citing you. Mentionable has no equivalent. Promptwatch also tracks Reddit and YouTube citations specifically, which matters more than it sounds: Promptwatch's own research on Reddit's collapsing share of ChatGPT citations (https://promptwatch.com/data/reddit-citations-are-dropping-in-chatgpt) shows reddit.com's share of ChatGPT Search citations fell from roughly 4% to 0.5% in a single day in August 2026, the kind of shift you'd want flagged automatically rather than discovered by accident.
Then there's the content side. Content Agents plan, write and publish GEO-optimized pages straight to Webflow, Framer or WordPress, and Unified Actions turns your visibility and crawler data into a prioritized to-do list instead of a dashboard you have to interpret yourself. Mentionable's MCP server lets you query your own data through an AI assistant, but it won't write the page for you.
Pricing: Essential $99/mo, Professional $249/mo, Business $579/mo, all with a 7-day free trial. That's more than Mentionable's Growth tier (EUR 79/mo), but you're paying for crawler logs, content generation and a materially bigger engine list.
Best for: teams that have outgrown "just tell me if I'm mentioned" and want a platform that also does something about the gaps it finds.
AthenaHQ
AthenaHQ is the other full-stack option, and it's worth a look specifically because it now has a genuinely free tier (Essential, 300 credits, unlimited members, tracking ChatGPT, Perplexity, AI Overviews, Gemini and Copilot) before you hit the $295/mo Starter plan. That's a lower bar to entry than Promptwatch or Scrunch, and notably lower than most of the category.
Where it differs from Mentionable: content optimization with brand-voice enforcement, citation intelligence that surfaces outreach opportunities, and agency workspaces with role-based access. Where it falls short of Promptwatch: no crawler-log equivalent, and several enterprise features (Knowledge Base/claim review, SSO, BI integrations) are locked to the custom Enterprise tier, so the jump from Starter to "actually enterprise-ready" is steep. Profound's own comparison blog calls out AthenaHQ as "not the best for enterprises" for exactly this reason, which is a fair point even coming from a competitor.
Best for: mid-market growth teams that want content optimization without committing to Promptwatch's higher starting price, and who are comfortable starting on a free tier before scaling up.
Semrush AI Visibility Toolkit
If you already pay for Semrush, the AI Visibility Toolkit is the path of least resistance: it plugs AI tracking into the same dashboard as your keyword, backlink and content data, and that context can genuinely help, since the entity and topical-authority signals that move your Google rankings also move your AI visibility.
But be careful with the "insights" it generates. One independent review (Overthink Group) documented the toolkit producing outright incoherent recommendations, including a math error claiming 2 x 5 = 12, and misidentifying which competitor a brand was actually losing ground to in a gap-analysis report. That's not a nitpick, it's the kind of thing that erodes trust in every other number on the dashboard. Semrush also reportedly dropped its free AI visibility tier after Adobe's $1.9 billion acquisition closed in August 2026, so AI tracking now starts around $99/mo as an add-on with no free trial.
Mentionable, by comparison, is a much smaller and more focused tool, but at least it isn't trying to generate automated strategic advice on top of the raw numbers.
Best for: existing Semrush customers who want AI visibility folded into their existing SEO workflow and are willing to sanity-check its auto-generated recommendations.
Otterly.AI
Otterly is the closest thing to a direct Mentionable competitor on price. The Lite plan is $29/mo (15 prompts) and the Standard plan is $189/mo (100 prompts, API, MCP, Looker Studio connector), both with a 14-day free trial.
The catch, and it's the same catch Mentionable solves: Otterly's base coverage is only 4 engines (ChatGPT, Google AI Overviews, Perplexity, Microsoft Copilot). Claude, Gemini and Google AI Mode are separate paid add-ons. If your brand lives or dies by Claude citations, that changes the real monthly cost quickly. On the plus side, Otterly does have GEO audits covering 25+ on-page factors, which Mentionable doesn't offer, and its tracking is daily by default rather than twice a week.
Best for: budget-conscious SMBs who mostly care about ChatGPT and AI Overviews and don't mind paying extra if they later need Claude.
Peec AI
Peec sits a notch above Otterly in price and depth. Current pricing is Starter EUR 85/mo (50 prompts, 3 models of your choice, 1 project), Pro EUR 205/mo, Advanced EUR 425/mo (350 prompts, multi-country tracking, Looker Studio), with Enterprise custom pricing unlocking up to 13 LLMs and SSO.
The standout feature here is actually the "act" side: Peec has brand-attribute and objection tracking, SKU-level AI Shopping visibility, a crawlability audit covering 40+ bots, and an AI agent with prebuilt and custom skills. That's meaningfully more action-oriented than Mentionable. The trade-off is the same one Otterly has: base tiers only include 3 models of your choice, and extra models, Claude specifically, are paid add-ons. Mentionable's flat 7-engine-for-everyone model is sim
