This article is part of our guide on how to track AI mentions.
Otterly is one of the more established AI visibility platforms, founded in 2023. Otterly is used primarily by agencies and marketing teams for brand monitoring across AI search engines, covering ChatGPT, Perplexity, Microsoft Copilot, and Google AI Overviews in its base plans.
If you're evaluating AI visibility tools, here's a detailed breakdown of how Otterly works, what Otterly costs, and how Otterly compares to Mentionable's full AI visibility stack.
How does Otterly track AI visibility?
Otterly monitors brand mentions across 4 LLMs (ChatGPT, Perplexity, Microsoft Copilot, Google AI Overviews) on a daily basis. Users manually define the search prompts to monitor, and Otterly checks daily whether the brand appears in AI-generated responses.
Otterly also provides GEO audits that analyze 25+ on-page factors influencing how AI models perceive content. These audits cover content structure, citation authority, and semantic relevance, with specific recommendations for improving LLM visibility.
Notably, Otterly does not include Google Gemini or Google AI Mode in its base plans. Both require paid add-ons ($9-$149/month depending on plan tier), which means tracking all major LLMs with Otterly costs more than the advertised base price.
Otterly supports tracking across 50+ countries, which is useful for brands running international campaigns or monitoring AI visibility across different markets.
How much does Otterly cost in 2026?
Otterly's Lite plan starts at $29/month for 15 prompts and 1 workspace. The Standard plan jumps to $189/month for 100 prompts with unlimited workspaces. Premium costs $489/month for 400 prompts.
Google Gemini and Google AI Mode are not included in any Otterly base plan. Both require paid add-ons costing $9-$149/month depending on the plan tier. Tracking all major LLMs with Otterly costs more than the advertised base price.
| Plan | Price | Prompts | LLMs included | Workspaces |
|---|---|---|---|---|
| Lite | $29/month | 15 | 4 | 1 |
| Standard | $189/month | 100 | 4 (+add-ons) | Unlimited |
| Premium | $489/month | 400 | 4 (+add-ons) | Unlimited |
| Enterprise | Custom | Custom | All | Unlimited |
Additional prompts can be purchased at $99/month per 100 prompts.
What does Otterly do well?
Otterly's GEO audit feature is genuinely useful. While most AI visibility tools only report whether a brand is mentioned, Otterly analyzes 25+ on-page factors and provides specific recommendations for improving content for LLM citations.
Otterly's daily tracking frequency means brands catch visibility changes within 24 hours. If a competitor starts appearing more frequently in ChatGPT responses, Otterly surfaces that quickly.
Otterly's workspace system is well-designed for agencies managing multiple client accounts. All Otterly plans include unlimited team members, which removes per-seat pricing friction.

What does Mentionable offer beyond basic tracking?
Otterly focuses on brand monitoring with on-page GEO audits. Mentionable provides a broader AI visibility stack with deeper competitor and source intelligence, plus two differentiators unique to Mentionable in April 2026: a public MCP server and a one-shot white-label GEO audit.
- 7 LLMs to pick from, no add-ons. Otterly's base plans include 4 LLMs. Google Gemini and AI Mode cost extra ($9-$149/month). Mentionable lets users choose 3 LLMs on Growth, 4 on Pro, and up to 7 on Agency across ChatGPT, Perplexity, Gemini, Grok, Copilot, Google AI Mode, and Google AI Overview, with no add-on costs.
- Automatic prompt generation. Otterly requires manual prompt entry. Mentionable scans the user's URL and auto-generates 15-20 relevant prompts, saving setup time.
- Full competitor and source stack. Mentionable extracts and ranks every competitor mentioned alongside the user's brand, tracks every source domain cited by LLMs, and surfaces content opportunities. Otterly focuses on brand mention monitoring.
- MCP integration. Mentionable is an AI visibility tracker with an MCP server. Users can query their visibility data directly from Claude Desktop, Cursor, ChatGPT, or Claude Code. Otterly does not offer MCP access.
- One-shot white-label GEO audit (Agency). The Mentionable Agency plan includes a client-ready GEO audit with 6 sections: competitor podium, prompt coverage heatmap, top citation sources, quality backlinks, AI-generated diagnostic, and recommended content plan. Otterly's GEO audit analyzes on-page factors but is not a packaged deliverable for consultants to hand to clients.
- AI traffic attribution. Mentionable's tracking pixel identifies visits from LLMs that appear as "direct" in Google Analytics. Otterly does not offer traffic attribution.
- Scalable pricing. Mentionable Growth is €79/month for 40 prompts, Pro is €149/month for 80 prompts across 4 projects, and Agency is €299/month with 5,000 credits, unlimited projects, and up to 7 LLMs.
Start tracking your AI visibility across 7 LLMs with Mentionable's 4-day free trial, no credit card required.
