Otterly.ai vs Heuriso: Features, Pricing and How They Work

Otterly vs Heuriso at a glance

The key differences in one place. Each row is covered in more detail below.

Which AI engines they track and how they collect answers

Both tools query AI models through the same interfaces people use, not through an API. That’s a real advantage: an answer in the ChatGPT or Perplexity window includes web search results and cited sources that an API often doesn’t return, so you see what your customer sees. The one exception is Claude in Otterly, which is accessed through an API. Every Otterly plan tracks four engines: ChatGPT, Google AI Overviews, Perplexity and Microsoft Copilot. Gemini, Google AI Mode and Claude are paid add-ons whose cost rises on higher plans. Heuriso covers five engines: ChatGPT, Gemini, Perplexity, Google AI Overviews and Microsoft Copilot. The Freelancer plan includes the first three, and PRO and Agency include all five at no extra cost.

Prompts

Both tools detect your website’s language when you add it and generate prompt suggestions in that language. You can edit or delete the suggestions and add your own prompts.

They differ in the kind of suggestions they make. Otterly mostly generates long, detailed questions (long-tail), such as “which travel agency in Denver has the best last-minute deals on domestic trips”. Heuriso mixes short phrases with long-tail questions, so alongside detailed questions you also get broad ones such as “travel agency Denver”. That way you can see whether your brand appears both for broad category searches and for specific buying questions. Heuriso also groups prompts into topics, which makes it easier to see which parts of your offer are visible and which are missing.

Whichever tool you use, review the generated prompts. They should sound like the questions your real customers ask.

Features: what you get in each tool

Brand visibility and Share of Voice

Both tools answer the same question: how often, and in which position, does AI mention your brand? Otterly shows Brand Coverage, the share of answers that mention your brand, along with position and Share of Voice against competitors. Heuriso goes a step further: Visibility Score combines in one number not only whether your brand appears, but where it appears in the answer and in what tone AI talks about it. A mention at the bottom of a list, or one with a caveat, counts for less than a first-place recommendation. Next to the score you’ll see Share of Voice, the number of mentions and the trend over time.

Competitors in AI answers

In Otterly, you pick the brands you want to compare yourself with. In Heuriso, competitors are pulled automatically from AI answers, so you see the companies models actually recommend next to your brand, including ones you might not have thought of. You can then add brands by hand or remove ones that aren’t real competitors. In both tools you can check which brands AI recommends, how often and in which position. When choosing competitors, think about your client’s market: comparing a local business with global brands says little about who AI recommends in its city.

Cited sources

Both tools analyze cited sources in a similar way. They count both domains and the specific URLs AI cited, track changes over time and classify each domain, for example as an industry publication, a forum, a roundup or a company website. So you see not only where AI gets its information, but which kinds of pages carry the most weight in your industry. That tells you where it’s worth being present: the pages AI relies on are also where your competitors appear.

Query fan-out

Fan-out queries are the extra searches a model runs to find the information it needs for an answer. Otterly shows predicted fan-out queries, while Heuriso records the queries read from the actual answers. In Heuriso you’ll see them for ChatGPT and Perplexity answers. They’re a useful input for content planning: if the model searches for “affordable accountant boston reviews”, you can check whether your client’s website covers that topic.

Recommendations and action plan

After a few days of monitoring, both tools generate a list of actions with a rationale and a priority, which you can add to your task list. The actions are different in nature, though. Otterly focuses mainly on content on your own site: it suggests new pages with a ready-made title, based on the prompts where your brand is missing and on competitor pages that AI cites. The implementation tips look similar for every task: write comprehensive content, analyze competitor pages, add structured data. Otterly also adds diagnostic alerts, for example when your brand doesn’t appear in any answer.

From the PRO plan up, Heuriso builds an action plan that covers both your presence on other websites and the content on your own site. Tasks appear only where the data points to a problem, so the list is shorter. A typical off-site task is “get a mention on the 4 pages AI cites for topic X”, with the list of URLs, how often the model used them, steps for each page and the condition that marks the task as done. Content tasks are based on fan-out queries: Heuriso suggests new content, or an update to an existing page, for the searches the model ran while answering your customers’ questions. In both tools these are suggestions to consider, not a guarantee of higher visibility.

Pricing and plans

Prices below were checked on Otterly’s pricing page on October 26, 2026, with monthly billing. Otterly shows prices in your local currency and lower rates for annual billing; add-on prices are listed before tax. See Otterly’s pricing.

Extra engines cost more. On Lite, Gemini and Google AI Mode cost $9 a month each, and Claude $29. On Standard, Gemini and AI Mode cost $59 each and Claude $109; on Premium, $149, $149 and $439 respectively. On Standard and Premium, every additional 100 prompts costs $99 a month.

Prompt limits are a shared pool for the whole account that you split across projects or reports, not a separate limit per client. Otterly explains how prompts are counted in its help center.

Example: an SEO freelancer with three clients

What you pay depends mostly on which AI engines you need.

Scenario A: ChatGPT, Gemini and Perplexity. These are three of the most widely used AI engines, each with a large user base. Heuriso Freelancer covers them for $29 a month. On Otterly Lite you have to add Gemini, so the price goes up to $38, and the limit is 15 prompts instead of 20. In this scenario Heuriso is cheaper.

Scenario B: ChatGPT, AI Overviews, Perplexity and Copilot. Otterly Lite covers these four engines for $29 a month and lets you track 15 prompts, five per client. With one project per client, Heuriso Freelancer fits the three-project limit, but it doesn’t include AI Overviews or Copilot. To track all four engines, you need the PRO plan at $79, which includes 100 prompts. In this scenario Otterly is clearly cheaper.
