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 4-day free trial on all plans. Paid plans start at €79/month Growth (40 prompts, 3 LLMs chosen from 7, 2 projects), then €149/month Pro (80 prompts, 4 LLMs, 4 projects), and Agency at €299/month with 5,000 credits, unlimited projects, and up to 7 LLMs.
Otterly doesn't offer a free tier, but they have a 4-day trial. Their Lite plan starts at $29/month with 15 prompts across 4 LLMs. The Standard plan jumps to $189/month for 100 prompts and unlimited workspaces. One thing worth noting: Google Gemini isn't included in the base plans. If you need it, that's an additional $9 to $149/month depending on your tier.
The math shifts based on your needs. Mentionable lets you choose from 7 platforms (ChatGPT, Perplexity, Gemini, Grok, Copilot, Google AI Mode, Google AI Overview) without surprise add-ons: 3 LLMs on Growth, 4 on Pro, up to 7 on Agency. Otterly's add-on structure can push costs up if you need specific platforms like Gemini.
What Mentionable does well
The MCP integration is what sets Mentionable apart from every other tool in this category. Mentionable ships a public MCP server. 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 is dashboard-only.
Every paid plan lets you pick from the full 7-LLM roster. No figuring out which platforms cost extra, no surprise fees. Growth activates 3 LLMs of your choice, Pro 4, Agency up to 7. Otterly's add-on structure (notably Gemini at $9 to $149/month extra) can push costs up if you need specific platforms.
The 4-day free trial lets you plug Mentionable into your AI agent and run a real workflow before paying. Less commitment to test if the integration changes how you work.
Agency customers get a one-shot GEO audit: a client-ready white-label report (competitor podium, prompt coverage heatmap, top citation sources, quality backlinks, AI-generated diagnostic, recommended content plan). 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 15 to 20 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 (6-section 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's more affordable plans track weekly or bi-weekly, which is fine for most use cases but less granular.
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. The MCP integration plus 7-LLM coverage on every plan makes 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, multi-country tracking (50+), or daily checks per project, 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 4-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.
