If you're comparing Mentionable and Otterly, you've already figured out that AI visibility matters. Both tools track how LLMs see your brand, but they take fundamentally different approaches: Otterly is a dashboard-first tracker, Mentionable is a GEO data layer that plugs into your AI agent.
How they compare at a glance
Mentionable offers a 7-day free trial, no credit card required. Paid plans start at €79/month Growth (up to 115 prompts, all 7 AI engines, 1 project), then €149/month Pro (up to 231 prompts, all 7 AI engines, 3 projects), and Agency at €299/month with 5,000 credits, unlimited projects, and all 7 AI engines.
Otterly doesn't offer a free tier, but they have a free trial. Their Lite plan starts at $29/month with 15 prompts across 4 engines (ChatGPT, AI Overviews, Perplexity, Copilot). The Standard plan jumps to $189/month for 100 prompts and unlimited workspaces. One thing worth noting: Google AI Mode, Gemini and Claude aren't included in the base plans. Each is a paid add-on (Gemini alone is an additional $9 to $149/month depending on your tier).
The math shifts based on your needs. Mentionable includes all 7 AI engines (ChatGPT, Claude, Perplexity, Gemini, Copilot, Google AI Mode, Google AI Overview) on every plan without surprise add-ons. Otterly's add-on structure can push costs up if you need specific platforms like Gemini or Claude.
What Mentionable does well
Mentionable was built as a GEO data layer for your AI agent. Its MCP server, included on Pro and Agency, lets you plug it into Claude Desktop, Cursor, Claude Code, n8n or any MCP-compatible client and your AI agent queries your tracking, fan-out queries, citations and competitors directly. No tab-switching, no copy-pasting. Your briefs, audits and status checks come out with your real GEO data underneath. Otterly also offers MCP from its Standard plan, but its workflow remains dashboard-first.
Inside the dashboard, every plan also includes an AI assistant. Ask it why a competitor gets cited more often and it answers from your own tracking data, then links to the page where you can act.
Every paid plan includes the full LLM roster. No figuring out which platforms cost extra, no surprise fees. All 7 AI engines are available on every plan, Claude included. Otterly's add-on structure (notably Gemini at $9 to $149/month extra) can push costs up if you need specific platforms.
The 7-day free trial lets you track your own prompts and see real results before paying, no credit card required. MCP access then comes with the Pro and Agency plans.
Agency customers get a one-shot GEO audit: a client-ready white-label report (competitor ranking, personas, competitor matrix, prompt coverage, recommendations, content ideas, top sources). Useful for consultants and agencies who need a shareable deliverable to send clients.
The prompt suggestion feature is useful if you're not sure what to track. Enter your URL, and Mentionable suggests up to 40 relevant prompts based on what your business does. You pick the ones that matter, add custom ones if you want, and start tracking. Less research upfront.
What Otterly does well
Otterly's GEO audits analyze 25+ on-page factors that influence AI visibility. If you want to understand why you're not appearing (not just that you're not), this gives you actionable data to work with. Note that Otterly's audit is an on-page factor report, not a client-ready deliverable. Mentionable Agency's one-shot GEO audit is structured differently (a white-label report made for sharing with clients).
Their workspace organization is built for agencies managing multiple clients. Mentionable has projects, but Otterly's structure is designed specifically for agency workflows with client separation.
Geographic coverage is another strength. Otterly supports 50+ countries with localized tracking. If you're running international campaigns and need to know how AI responds in different markets, that matters.
Otterly also checks daily by default. Mentionable does the same on every plan, so scan frequency is not what separates the two.
Which one fits your workflow?
If your daily tool is already an AI agent (Claude Desktop, Cursor, n8n, or any MCP client) and you want it to work with your real GEO data instead of generic suggestions, Mentionable is built for that. All 7 AI engines on every plan, plus the native MCP integration on the Pro and Agency plans, make it the right starting point for consultants, founders and in-house teams who want to stop copy-pasting from dashboards.
If your workflow lives inside a dashboard and you need detailed on-page GEO audits or multi-country tracking (50+), Otterly's depth matches those requirements. The higher price reflects the broader feature set.
Both are solid tools. The choice comes down to where your workflow happens. Try Mentionable's 7-day free trial first if you want to plug GEO data into your AI stack. Look at Otterly if you need on-page audit depth and geographic coverage in a standalone dashboard.
