There are comparison pages written to make the other product look small. This is not one of them. Otterly does its job well at a price almost anyone can justify, and plenty of readers of this page should buy it. What follows explains where the two products part ways, so you spend the right amount for the stage you are at. The full market view is in our UK B2B AI visibility tools roundup.
What is Otterly.AI?
Otterly.AI is an AI search monitoring tool from Austria, founded in 2024 by Thomas Peham, Klaus-M. Schremser and Josef Trauner, a team with a previous exit (Usersnap) behind them. It has grown past 30,000 users as a lean, focused company, picked up a Semrush technology partnership in January 2025, and won at the European Search Awards 2026.
The product does what it promises: it monitors AI search and shows you where your brand appears, with a setup process that takes minutes rather than meetings. Pricing starts at $29 per month; current plans are on Otterly.AI's pricing page.
How much does Otterly.AI cost?
Otterly.AI starts at $29 per month, which makes it one of the most affordable ways into AI visibility monitoring anywhere in the market. At that price the decision barely needs a business case: if AI search matters to you at all, $29 per month to see whether you show up is easy to justify.
For contrast, our ladder starts free (the AI Visibility Check, then Sentinel Free with one brand, five prompts, a monthly refresh and category history included) and runs through Sentinel Basic at £199 per month, Standard at £499 and Pro at £999, then Fortitude Forge from £3,950 per month. We are not the cheap option and we do not pretend to be. The two products are priced for different jobs, which the rest of this page explains.

What Otterly.AI does well
Plenty, which is why it has passed 30,000 users.
- The lowest-friction entry point in the market. From $29 per month with a setup measured in minutes, Otterly removes every excuse for not knowing whether AI mentions your brand. As a first step into AI visibility, nothing beats it on effort-to-insight.
- Recognition that means something. A Semrush technology partnership since January 2025 and a European Search Awards 2026 win are independent signals of quality, not self-awarded badges.
- Lean and focused. Otterly has grown to 30,000+ users as a lean company doing one job well, without bloating the product or the price. That discipline shows in how quickly you get value from it.
Where Fortitude is different
The difference is depth and destination, not quality. Otterly answers "does AI mention us?" quickly and cheaply. Fortitude exists for everything that question opens up.
Depth: buyer-intent prompts and named competitors. Sentinel runs a canonical library of buyer-intent prompts per category, the questions real buyers ask when they are choosing, and reports named-competitor share of voice across them. Knowing you are mentioned is the start; knowing that two named rivals appear in answers where you do not, and in which buying scenarios, is what you can act on. Our prompt design is documented on our methodology page.
Coverage: five engines including Claude. Sentinel tracks ChatGPT, Claude, Gemini, Perplexity and Google AI Overviews on every tier, including the free one. Check otterly.ai for their current engine list and make sure the engines your buyers actually use are covered before you commit to any tool, ours included.
History: your category's past, on day one. Any monitoring tool starts recording when you subscribe. The Registry, our longitudinal record of how AI engines answer buyer-intent prompts per category, means new Sentinel customers receive up to twelve months of their category's history at signup. Month one arrives as a trend, not a baseline, and trends are what reveal whether an engine has been drifting towards a competitor for two quarters.
Destination: the work gets done. This is the largest difference. Monitoring, at any depth, describes the problem. Our ladder ends with Fortitude Forge, from £3,950 per month, where we do the content, digital PR and website work, with delivery quoted as human-equivalent time at roughly half human-equivalent cost (the in-house alternative runs £165k to £255k per year), and the results reported on the same Sentinel chart that found the problem. We have not found another UK provider that combines a tracking platform and a managed delivery service on one continuous ladder from free to full service. If you are unsure whether you need a tool, an agency or both, that exact guide is the place to start.
A fair summary: monitoring versus moving the number. Otterly is a very good way to watch the number. Fortitude is built so that, when you are ready, someone owns making it go up.
Choose Otterly.AI if... / Choose Fortitude if...
Choose Otterly.AI if:
- You just want to know whether AI engines mention your brand, at the lowest price and effort in the market. We mean it: start there.
- Your budget for this sits at the $29 per month level and a clear monitoring signal is all you need this quarter.
- You value fast setup and a focused tool over depth you may not use yet.
- You are pre-revenue or early stage and the considered-purchase dynamics of UK B2B do not apply to you yet.
Choose Fortitude if:
- You need to know which named competitors AI recommends instead of you, across buyer-intent prompts, not just whether you are mentioned.
- Claude coverage matters: our five engines include it on every tier.
- You want up to twelve months of your category's history on day one rather than starting from zero.
- You want a ladder that ends with the work being done, by the same company that measures it, accountable to the same chart.
