Otterly.AI vs Promptwatch at the entry end of AI visibility

Two cheap ways in that are not the same product

Most comparisons in this category are between products aimed at companies with a procurement process. This one is not. Otterly.AI and Promptwatch are both reachable by a marketing team with a corporate card, and both publish enough on their pricing pages to be evaluated without a call. That makes the differences unusually easy to see, and unusually decisive.

Otterly.AI's pricing page, fetched on 3 September 2026, sells search prompts. Lite is $29 a month for fifteen. Standard is $189 for a hundred. Premium is $489 for four hundred. Enterprise is custom, stated as starting from $1,000 a month. Every tier tracks the same four assistants — ChatGPT, Google AI Overviews, Perplexity and Microsoft Copilot — and every tier carries unlimited team members. Annual billing takes 15 percent off, bringing Lite to $25, Standard to $160 and Premium to $422.

Promptwatch's pricing page, fetched the same day, sells subscriptions. Explore is $0. Essential is $95. Professional is $245. Business is $579. There is a custom option, and a toggle separating brands from agencies. What the page does not carry is a prompt count, a seat count, or a per-tier statement of which models are watched. Its site says the product monitors all AI models and names ChatGPT, Gemini, AI Overviews, Claude and Grok among them.

Those are two different theories of what you are buying. Otterly thinks you are buying a measured quantity of monitoring. Promptwatch thinks you are buying access to a tool. Both are defensible, and they lead to very different evaluations.

The allowance question, which is the whole comparison

If you can only look at one row, look at this one. Otterly tells you what its price buys and Promptwatch does not.

The practical consequence is that an Otterly quote can be turned into a cost per tracked prompt and a Promptwatch quote cannot. At $189 for a hundred prompts, Otterly Standard is a number you can defend in a budget meeting and revisit when your prompt set grows. Promptwatch Professional at $245 might be much better value or much worse, and nothing on the page settles it.

This cuts against Promptwatch in a shortlist, but it is worth being precise about what the criticism is. It is not that Promptwatch is expensive — it may well not be. It is that the page does not let you find out, so a buyer who needs to model cost against a growing prompt set has to open a conversation to do arithmetic that Otterly lets them do in a browser tab. For a self-serve purchase, that is real friction, and it is the reason a lot of teams shortlist Otterly and never get as far as asking Promptwatch.

The reverse criticism applies to Otterly and is just as real: a published allowance is only reassuring if the allowance is enough. Fifteen prompts is not a category. It is a handful of queries you have decided in advance are the important ones, which assumes you already know which queries matter — often the very thing you bought the tool to find out. Otterly's honest entry point for a real programme is Standard, at $189, and that lands above Promptwatch's Essential at $95.

Coverage: four named assistants against an unbounded claim

Otterly names four assistants and holds the list constant across every tier. ChatGPT, Google AI Overviews, Perplexity and Microsoft Copilot. Nothing on the pricing page indicates that a more expensive plan watches more of them; what you buy as you move up is prompts.

Promptwatch states that it monitors all AI models, and its site names ChatGPT, Gemini, AI Overviews, Claude and Grok among them.

Two of those named models — Claude and Grok — do not appear on Otterly's published list at all. This is the one place in this comparison where the difference is not a matter of packaging philosophy but of what the product does. If your buyers ask Claude about your category, or if Gemini matters to you, Otterly's published four does not cover it and Promptwatch's stated list does. That is a concrete reason to choose Promptwatch, and it does not depend on price.

The counterweight is enforceability. "All AI models" is a claim with no boundary, and the pricing page does not attach it to a tier. Otterly's four is a smaller promise that is easier to hold the vendor to. In an evaluation, ask Promptwatch to confirm in writing which models your plan actually watches, and treat the answer, not the homepage line, as the fact.

What the pages say about who is buying

Promptwatch names its buyer out loud: agencies managing AI search for multiple brands. Its price ladder is consistent with that, since a $95 tier can be attached to a client engagement in a way that a $295 floor cannot, and the pricing page carries a brands-versus-agencies toggle.

Otterly does not narrow its buyer on the page, but the shape of the product implies one. Unlimited team members on every plan, including the $29 tier, plus API and MCP access from Standard upward, describes a team that wants the data somewhere other than the vendor's dashboard. The MCP line is the most interesting detail on either page: it means visibility data can be read from inside an AI assistant, which is a small but genuinely differentiated capability that Promptwatch's pricing page does not mention.

The trial and the free tier are not the same offer

Otterly states that a free trial is provided for new users with no commitment required before purchase. It does not state a length. Promptwatch offers a plan priced at zero rather than a time-boxed trial, which never expires but whose limits the page does not describe.

For this category, the free plan is the better structure in principle, because AI visibility numbers only stabilise over weeks and a short trial often ends before the data means anything. But Promptwatch's version gives you no way to know in advance what the free plan will let you see, so the advantage is theoretical until you sign up. Otterly's is time-bounded but at least tells you which product you are trying, because its tiers are explicit.

The middle of the ladder, where most teams actually land

Entry tiers get the attention and middle tiers get the money, so it is worth walking the ladder properly.

Otterly's ladder is arithmetic. Fifteen prompts at $29, a hundred at $189, four hundred at $489, and an enterprise conversation stated as starting from $1,000 a month. Divide those out and the cost per tracked prompt falls sharply as you climb — the Lite tier is by far the most expensive per prompt, and Premium the cheapest of the self-serve three. That is the normal shape of volume pricing, and it means Otterly rewards a team that knows its prompt set is going to grow. Annual billing takes a further 15 percent off, publishing $25, $160 and $422 as the discounted monthly rates, which is a discount you can budget against rather than negotiate for.

Promptwatch's ladder is $0, $95, $245, $579 and custom, with no allowance attached to any rung. What that means practically is that you cannot tell whether moving from Essential to Professional buys you more prompts, more brands, more models, more history, or something else entirely. The page presents the ladder as a progression and does not say what progresses.

Between the two, the interesting overlap is around $189 to $245. Otterly Standard at $189 gives you a hundred prompts, four assistants, unlimited seats, and API plus MCP access. Promptwatch Professional at $245 gives you a tool that says it monitors all AI models, including Claude and Grok, and does not say how many prompts it will monitor them for. If your category lives on ChatGPT and Perplexity, the Otterly side of that trade is easy to justify. If your buyers are developers who ask Claude, the Promptwatch side is, and no amount of published arithmetic changes it.

The enterprise floors are worth noting too, because they are rarely published at all. Otterly states that its custom tier starts from $1,000 a month. Promptwatch's Business tier is $579 with a custom option above it and no stated floor. Knowing where the sales conversation begins is genuinely useful when you are deciding whether to start one, and Otterly is the only side of this pairing that tells you.

Where each one wins

Otterly.AI wins on transparency and on unit economics. Every tier states its prompt count, seats are unlimited from $29, annual pricing is published, API and MCP access are named, and even the enterprise conversation has a published floor. A buyer can build the entire business case from the pricing page, which is rarer in this category than it should be.

Promptwatch wins on coverage and on entry. It names Claude and Grok, which Otterly's published list does not include; it has a genuinely free plan rather than a trial; and its paid ladder starts at $95, below the $189 tier where Otterly's prompt allowance becomes realistic for most categories. If you are an agency, it also says, in its own words, that it was built for you.

Neither is the right answer for a team with several hundred prompts and a tight budget. Otterly's four hundred prompts costs $489 a month and Promptwatch will not tell you what its equivalent is. That is the point at which this shortlist should widen rather than narrow.
