One of these tools costs $29 a month to start. The other starts at $99 and goes deeper than almost anything else in the category. So PromptWatch versus Otterly is not really a fight over who is best. It is a question of how much depth you need, and how much you want to spend to get it. We use PromptWatch every day to track Arfadia's own AI visibility, so we will be upfront about our bias, then give Otterly a fair hearing, because for some teams it is the smarter buy.

PromptWatch in Brief
PromptWatch is an all-in-one AI visibility platform that tracks how your brand shows up across more than ten engines, including ChatGPT, Gemini, Claude, Perplexity, Google AI Overviews and AI Mode, Meta, DeepSeek, and Grok. It does not stop at measurement. The Answer Gap report finds prompts where competitors appear and you do not, then helps you generate articles to close the gap. It also tracks citations from YouTube and Reddit, logs how AI crawlers hit your site, and reports real referral traffic from AI platforms. Pricing is transparent and self-serve, running from around $99 a month to about $579 a month, with a 7-day free trial. It is the tool we run for Arfadia and our clients, and we cover it in depth in our PromptWatch review.
Otterly AI in Brief
Otterly is the easiest, cheapest way into AI search monitoring. Its Lite plan starts at $29 a month for around ten tracked prompts, with Standard at $189 for 100 prompts and Pro at $989 for 1,000, on a transparent prompt-based model. It covers six engines in total, but only four come in the base plans: Google AI Overviews, ChatGPT, Perplexity, and Microsoft Copilot. Google AI Mode and Gemini are paid add-ons that run from $9 to $149 a month depending on your tier. Where Otterly earns real credit is its GEO audit and predictive scoring, which estimates how likely AI engines are to cite a page before you publish it, plus content briefs and a tidy Semrush integration. It is monitoring and guidance, not content generation, and it appeals strongly to budget-conscious teams and anyone already living in Semrush.

Where Each Tool Pulls Ahead
PromptWatch wins on breadth and execution. You track far more engines without paying extra, you see citations from YouTube and Reddit that most tools ignore, and you can generate content to fix the gaps you find, all in one place. For an agency running serious GEO work, that all-in-one depth saves real time. Otterly wins on price and friction. Thirty dollars gets you started, the interface is clean, and the predictive scoring that grades a page before you publish is genuinely useful. If you already run Semrush, the integration makes Otterly an easy add to a workflow you know.
Ten-plus engines, content generation, and gap-closing without bolt-ons or overages.

Engine Coverage: Why Breadth Matters
Here is a detail that is easy to miss. Your visibility is not one number, it is a different number on every engine, and the engines you track shape what you can even see. PromptWatch covers more than ten out of the box, so you catch where you stand on Claude, Grok, DeepSeek, and Meta, not only the big three. Otterly's base plans watch four, and two of the fastest-growing surfaces, Google AI Mode and Gemini, sit behind paid add-ons. If your buyers ask Gemini, that blind spot is real. It matters in dollars too. Traffic from AI answers converts well above ordinary search, as the numbers in our AI search and GEO statistics make clear, so missing an engine can mean missing your best-converting visitors. Catching and closing those gaps is the whole point of generative engine optimization.
The Real Cost at Scale
Otterly's prompt-based pricing is honest, but it climbs. Lite at $29 covers around ten prompts, fine for a single brand finding its feet. Step up to 100 prompts and you are at $189 for Standard, while serious tracking at 1,000 prompts runs $989, all before any add-ons for AI Mode or Gemini. PromptWatch's tiers, roughly $99 to $579, fold far more engines into every step. The rough rule of thumb: Otterly is cheaper to start, and PromptWatch is often cheaper once you track several brands or want full engine coverage, because you are not stacking prompt overages and per-engine add-ons. Run your own numbers against your real prompt count first. If you want help matching tools to an actual program rather than a price tag, that is what our GEO services are for.
Can You Use Both?
Some teams do, at least for a while. A common path is to start on Otterly for cheap, fast monitoring, learn what to track, then graduate to PromptWatch once you need broader engine coverage and content generation. Others keep Otterly inside their Semrush routine for quick checks while running PromptWatch as the deeper system of record. There is no rule against it. Just watch the combined cost, since Otterly's prompt-based pricing climbs quickly once you move past the Lite plan. For most teams, picking one and committing beats paying for two halfway.
How We Compared Them
The PromptWatch details come from our own daily use across Arfadia's projects and client work. The Otterly figures come from its public pricing and several independent 2026 reviews, since we do not run it day to day and will not pretend otherwise. Pricing and plan limits change often in this market, so confirm the current numbers on each vendor's site before you buy. Our aim here is an honest read of fit, not a feature count for its own sake.
The Verdict
PromptWatch is the deeper, broader tool, and it is the one we trust to watch Arfadia's place in AI answers. It earns the pick for any team that will actually use the breadth and wants to act inside one platform. Otterly is not a lesser version of that. It is a different, lighter product that nails the entry price, the ease of starting, and the rare trick of scoring content before you ship it. If money is tight, or you are testing the waters, or you already run Semrush, Otterly is a smart, honest choice. Match the tool to your stage, not to the longer feature list.
Whichever you pick, the score only improves when you do the work. Our guide to AI visibility optimization shows how, and our roundup of the best AI visibility and GEO tools ranks the full field.
