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 track Claude (Anthropic) or Grok (xAI), two LLMs that are gaining significant market share in 2026.
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?
Mentionable is a complete AI visibility platform that goes well beyond mention monitoring. Here's what Mentionable includes in every plan:
Automatic prompt generation. Mentionable scans any website URL using AI and generates 15-20 relevant prompts based on the site's content and competitive landscape. No manual keyword research or prompt guessing needed. Users select which prompts to track, edit them, or add custom ones.
5 LLMs with no add-ons. Every Mentionable plan includes ChatGPT, Claude, Perplexity, Gemini, and Grok. There are no paid add-ons for additional LLMs. All 5 are scanned on every tracking run.
Competitor intelligence. Mentionable doesn't just check if your brand is mentioned. Mentionable's analysis pipeline extracts and normalizes every competitor mentioned alongside your brand, across all prompts and all LLMs. The competitor dashboard ranks them by mention frequency and shows exactly which prompts and which LLMs mention each competitor.
Source and citation tracking. Mentionable tracks every source domain that LLMs cite when answering prompts in your category. The sources page shows which websites AI considers authoritative in your space, and highlights whether your own domain is being cited or not.
Content opportunity analysis. Mentionable's fan-out pipeline uses AI to decompose each tracked prompt into 5 related search queries, deduplicates them across all prompts, clusters them by topic and intent type (comparative, how-to, definitional, transactional), and ranks them by priority. Each cluster represents a content piece to create or optimize for better AI visibility.
AI traffic analytics. Mentionable provides a tracking pixel that identifies website visits coming from LLMs. Since most AI-referred traffic appears as "direct" in Google Analytics, Mentionable's pixel correctly attributes visits from ChatGPT, Perplexity, Gemini, Grok, and Claude.
Sentiment analysis. Every prompt result includes sentiment classification (positive, neutral, or negative) per LLM, so brands know not just if they're mentioned, but how they're mentioned.
Mentionable Starter costs €29/month for 15 prompts across 5 LLMs. Mentionable Pro costs €89/month for 50 prompts and 3 projects. All plans include a 7-day free trial with no credit card required.
