Otterly AI Review: Features, Pricing, and the Free Alternative Worth Knowing

Otterly AI is an AI search visibility platform that tracks how your brand appears in ChatGPT, Perplexity, Google AI Overviews, Gemini, and Copilot. It is one of the most affordable and easiest tools to start with, priced from $29/month. The trade-offs are prompt caps, paid engine add-ons, and no free-forever plan, so it fits budget-conscious teams that want quick monitoring, not owners who want to run at scale for less.

What is Otterly AI?

Otterly AI is a Vienna-based monitoring platform for answer engine optimization (AEO), launched in 2024 and built for marketers and agencies who want to measure AI visibility quickly. It tracks whether AI answer engines name your brand, link your site, and which sources they cite. It earned a place on Gartner's 2025 Cool Vendors list for AI in marketing and reports a user base in the tens of thousands.

The core idea behind Otterly AI is a shift from keywords to prompts. Instead of asking "where do I rank for this term," it asks "does the AI mention my brand when a user asks this question." That reframing matters because answer engines increasingly return one synthesized answer rather than a list of blue links, so presence inside the answer becomes the metric that drives discovery.

Which AI engines does Otterly AI track?

Otterly AI tracks seven surfaces in total: ChatGPT, Perplexity, Google AI Overviews, Google AI Mode, Gemini, Microsoft Copilot, and Claude. The important detail is that core plans include only four engines. Gemini and Google AI Mode are billed as paid add-ons, so teams that need full coverage should price those extras before comparing Otterly to all-in tools.

This add-on model is easy to miss when you compare base plan prices. A $29 headline rate covers four engines; adding the two Google surfaces most brands care about pushes the real monthly cost higher. Always compare tools against the exact engine list you need, not the label on the cheapest tier.

What features does Otterly AI offer?

Otterly AI covers the full monitoring loop: it finds the prompts that matter in your category, checks them daily across engines, stores answers for historical comparison, and recommends fixes. Alerts flag when visibility drops, which helps with brand-crisis situations. The feature set is broad for the price and aimed at non-technical marketers who want results within an afternoon.

Its main features include:

• Brand Visibility Index, how often your brand appears across your tracked prompts.

• Link Citations Analysis, every domain and URL cited in AI answers, checked over time.

• GEO Audit with SWOT, a structured read on where your content is strong or weak for AI.

• Prompt and keyword research, generates prompt variations and query fan-out from seed keywords.

• Crawlability Checker and Content Audit, audits whether AI bots can access and use a page.

• API and MCP server, available on higher tiers for teams that want to pull data into their own stack.

• Multi-country tracking, coverage across 50-plus markets, with unlimited team members on every tier.

How much does Otterly AI cost?

Otterly AI uses three self-serve tiers plus a custom Enterprise plan, with roughly 15% off annual billing. There is a 7-day free trial with no credit card and around 50 prompts, but no free-forever plan. Prices scale mainly on prompt volume and engine add-ons rather than seats.

Two costs are easy to overlook. Prompt overages run about $99 per 100 extra prompts, and the Gemini and Google AI Mode add-ons are billed separately. For a small brand tracking a handful of prompts, Lite is a real plan. For anyone monitoring dozens of prompts across all engines, the effective monthly cost climbs quickly.

What are Otterly AI's pros and cons?

Otterly AI's biggest strength is accessibility: transparent public pricing, a usable $29 entry tier, and fast self-serve onboarding. Its biggest weakness is that everything meaningful, more prompts, more engines, API access, sits behind higher tiers or add-ons, and there is no free option to run indefinitely.

Pros

• Genuinely usable entry plan at $29/month, not a decoy tier.

• Transparent, published pricing with no "contact us" wall until Enterprise.

• Unlimited team members on every plan.

• Broad engine coverage and 50-plus market tracking.

• Gartner Cool Vendor recognition and a large, established user base.

Cons

• No free-forever plan, the trial is time-limited.

• Gemini and Google AI Mode cost extra, inflating the real price.

• Low prompt ceilings on lower tiers; overages are expensive.

• Output-only monitoring, it tracks what AI shows, not real crawler visits to your site.

• You pay a platform subscription on top of the underlying AI usage.

Who is Otterly AI best for?

Otterly AI is best for small in-house teams, solo marketers, and agencies that want to start measuring AI visibility this week without a procurement process. It suits users who track a modest prompt set, value a clean interface over deep configuration, and are comfortable paying a fixed monthly subscription for convenience.

It is a weaker fit for brands that need to track many prompts across every engine, teams that want to own their raw data, and owners who would rather pay AI providers directly than pay a platform markup on every response. Those needs point toward a bring-your-own-tokens model instead.

What is the main limitation of Otterly AI?

The main limitation of Otterly AI is its cost structure: you pay a monthly platform fee, and that fee bundles both the software and the AI usage into one marked-up subscription. As your prompt count and engine list grow, the price scales with them, and the two Google engines many brands care about are not even included in the base plans.

This is the standard model across most AI visibility tools, and it is exactly where a free, bring-your-own-tokens platform changes the maths, because it removes the platform markup entirely and lets you pay the AI providers directly for only what you use.

Otterly AI vs a free, bring-your-own-tokens alternative

If your main hesitation with Otterly AI is the subscription and prompt caps, Llumo is worth a direct comparison. Llumo is a free, self-hostable AI visibility platform: you connect your own API keys, pay the providers directly, and use the platform itself at no cost, with unlimited projects and no per-engine add-ons.

The cost difference is concrete. As a worked example, monitoring 150 prompts daily across seven engines costs roughly $100/month in direct API fees with Llumo, while the platform stays free, versus a subscription plus add-ons on a tool that caps prompts and gates engines. Many API providers also offer free credits for small users, so a brand tracking a light prompt set can often run Llumo at close to zero.

For agencies specifically, Llumo runs every client from one workspace through its AI visibility tracker for agencies, and teams focused on a single engine can start with the free ChatGPT tracker. The positioning is simple: Otterly rents you access to AI visibility data; Llumo hands you the platform and lets you own the data and the spend.

Frequently asked questions

Is Otterly AI free? 

Otterly AI is not free to use long-term. It offers a 7-day free trial with no credit card and around 50 prompts, but there is no free-forever plan. The cheapest paid tier is Lite at $29/month. Teams wanting an ongoing free option should look at bring-your-own-tokens platforms like Llumo, which stay free and charge only for direct API usage.

How much does Otterly AI cost? 

Otterly AI costs $29/month for Lite, $189/month for Standard, and $489/month for Premium, with a custom Enterprise tier and roughly 15% off annual billing. Prompt overages run about $99 per 100 prompts, and Gemini and Google AI Mode are paid add-ons, so the real cost depends on your prompt volume and engine list.

Which AI engines does Otterly AI track? 

Otterly AI tracks ChatGPT, Perplexity, Google AI Overviews, Google AI Mode, Gemini, Microsoft Copilot, and Claude. Core plans include only four engines, and Gemini plus Google AI Mode are billed as add-ons. Compare any tool against the exact engines you need rather than the base-tier label.

What are the best Otterly AI alternatives? 

Common Otterly AI alternatives include Profound, Peec AI, Scrunch AI, and Llumo. Profound and Peec target larger teams at higher prices, while Llumo takes a free, bring-your-own-tokens approach: you connect your own API keys, pay providers directly, and use the platform at no cost with unlimited projects.

Does Otterly AI track real AI crawler visits? 

Otterly AI focuses on output monitoring, it tracks what AI engines show in their answers, not real AI crawler visits to your website. To see whether AI bots are actually crawling your pages, you would pair it with server-log or crawler-tracking analysis, since output monitoring alone gives an incomplete picture of AI visibility.

Ready to Track AI Visibility Without the Extra Platform Cost?

Otterly AI is a solid option for teams that want simple, subscription-based monitoring. But if prompt limits, engine add-ons, and rising monthly costs are holding you back, Llumo offers a more flexible alternative. Connect your own API keys, track visibility across major AI engines, manage unlimited projects, and keep greater control over your data and usage costs. You pay the AI providers directly while the platform remains free.
