> Peec AI and Otterly.AI collect and count AI answers in similar ways. The difference is engine packaging: Otterly fixes four engines per prompt, Peec lets you choose three. For a buyer who wants Google's AI Mode and Gemini, that changes the cost of each useful answer.

[Peec AI](https://peec.ai) and [Otterly.AI](https://otterly.ai) both track how often AI answers mention a brand, and both sell plans you can buy online without a sales call. Both read answers from the AI apps that consumers use, both run every tracked question daily, and both price plans by the number of questions you track.

So what actually separates them? Our reading of both vendors' pricing pages and documentation, as of 15 October 2026, points to one decision: who chooses the AI engines each question runs on. Otterly fixes four engines for every question. Peec lets you choose three per project. That choice shapes which tool fits your buyers, what each useful answer costs, and what your headline number averages over.

## Why do the two tools look interchangeable?

First, the terms. A **prompt** is a question you ask the tool to track, such as "best CRM for small agencies". An **engine** is the AI product that answers it, such as [ChatGPT](https://chatgpt.com) or [Perplexity](https://www.perplexity.ai). An **answer** here means one prompt run on one engine on one day.

Both tools collect most answers through the public web interfaces of the AI apps, rather than through APIs, the paid programmatic access that AI companies sell to developers. Peec's documentation says it interacts with AI platforms "exactly as real users do". Otterly says the answers it captures are "identical to what your customers experience". Those are vendor claims; we found no independent test of either tool's accuracy.

The headline metrics are also built in a similar way. Peec's **Visibility** is the share of answers that mention your brand. Otterly's **Brand Coverage** is the share of prompt runs that mention your brand. Each one pools every engine you have switched on into a single percentage.

With so much in common, the feature lists alone do not separate the tools. The engine setup does.

## Which engines does each plan include, and who chooses them?

Otterly runs every prompt on four engines on all plans: ChatGPT, [Google AI Overviews](https://search.google/ways-to-search/ai-overviews/), Perplexity and [Microsoft Copilot](https://copilot.microsoft.com). Its pricing page sells [Google AI Mode](https://search.google/ways-to-search/ai-mode/), [Gemini](https://gemini.google.com) and [Claude](https://claude.ai) as paid add-ons. Its help centre does not say whether you can switch off one of the four base engines.

Peec's self-serve plans include three engines, chosen per project from six: ChatGPT, AI Mode, AI Overviews, Copilot, Gemini and [Naver AI](https://www.naver.com), the AI answer feature of the South Korean search portal Naver. Its documentation says three are selected by default and you can change them for each project. A fourth engine, including Perplexity, is a paid add-on. Claude appears only in the Enterprise column, marked "API".

*Engine packaging on self-serve plans, from each vendor's pricing page and help docs, 15 October 2026. Perplexity, Gemini and AI Mode sit on opposite sides in the two tools.*

| Engine | Otterly.AI | Peec AI |
|---|---|---|
| ChatGPT | Included on every prompt | One of six to choose from |
| Google AI Overviews | Included on every prompt | One of six to choose from |
| Microsoft Copilot | Included on every prompt | One of six to choose from |
| Perplexity | Included on every prompt | Add-on as a fourth engine |
| Google AI Mode | Add-on | One of six to choose from |
| Gemini | Add-on | One of six to choose from |
| Naver AI | Not listed | One of six to choose from |
| Claude | Add-on, collected via API | Enterprise only, marked "API" |

Otterly's help centre says it tracks Claude through the API, using the Haiku model with web search. That makes Claude in both tools a test of the model through its API, not monitoring of the consumer Claude app.

Those flipped lists lead straight to the bill.

## What does it cost to cover the engines your buyers use?

Start with list prices for the mid-tier plans, billed monthly. Otterly Standard costs $189 a month for 100 prompts. Peec Pro costs $245 a month for 150 prompts.

Add-on engines are priced per plan. On Standard, Otterly charges $59 a month each for AI Mode and Gemini. On Pro, Peec charges $85 a month for one extra engine. Peec's pricing page shows the lower annual-billing rate by default; we read the monthly rate from the price data in the page itself.

We priced two engine sets of four. Set A is Otterly's base four: ChatGPT, AI Overviews, Perplexity and Copilot. Set B is a Google-heavy set: ChatGPT, AI Overviews, AI Mode and Gemini. Each tool is priced on its own mid-tier plan, so the prompt counts differ: 100 at Otterly, 150 at Peec. The bills alone therefore do not compare like for like. Cost per answer does.

Our method is simple arithmetic. Answers per month are prompts × engines × 30 days. Cost per answer is the monthly price divided by those answers. A **wanted answer** is one from the four engines in the set; answers from any other engine the plan includes are not counted.

*Our calculation from list prices on monthly billing, read on both pricing pages on 15 October 2026. In Set B, Otterly's bill is lower, but each wanted answer costs more, because a third of its answers come from engines outside the set.*

| Scenario | Plan and add-ons | Price per month | Prompts × engines | All answers | Wanted answers | Cost per answer | Cost per wanted answer |
|---|---|---|---|---|---|---|---|
| Set A, Otterly | Standard | $189 | 100 × 4 | 12,000 | 12,000 | $0.016 | $0.016 |
| Set A, Peec | Pro + Perplexity | $330 | 150 × 4 | 18,000 | 18,000 | $0.018 | $0.018 |
| Set B, Otterly | Standard + AI Mode + Gemini | $307 | 100 × 6 | 18,000 | 12,000 | $0.017 | $0.026 |
| Set B, Peec | Pro + one extra engine | $330 | 150 × 4 | 18,000 | 18,000 | $0.018 | $0.018 |

In Set A, every Otterly answer is a wanted one, and its cost per answer is slightly lower. In Set B, Otterly has to add two engines to reach AI Mode and Gemini, while Perplexity and Copilot stay on. Of its 18,000 answers, 6,000 come from those two engines the set does not ask for. Peec's answers all come from the four engines chosen.

Annual billing lowers every price but does not change that pattern. Otterly's AI Mode and Gemini add-ons cost $610 a year each on Standard, about $51 a month.

*Our calculation on annual billing, shown as a monthly equivalent. The Set B gap per wanted answer narrows but remains.*

| Scenario | Price per month, annual billing | Cost per wanted answer |
|---|---|---|
| Set A, Otterly | $160 | $0.013 |
| Set A, Peec | $275 | $0.015 |
| Set B, Otterly | about $262 | $0.022 |
| Set B, Peec | $275 | $0.015 |

One more adjustment applies to AI Overviews. Google does not show an AI Overview for every search, and Otterly documents that it leaves those runs out of its counts. Its AI Overviews answers above are therefore a ceiling. Peec does not document how it counts runs where no Overview appears.

**What this means:** if your buyers use Perplexity and Copilot, Otterly's base plan covers them at the lower bill and a slightly lower cost per answer. If you want AI Mode and Gemini instead, Otterly charges for six engines to deliver four, and Peec's cost per wanted answer is lower.

The engine set changes more than the bill. It also changes what your headline percentage means.

## What does the headline number average over?

Both Visibility and Brand Coverage average across every active engine. Add an engine and you change the average, even if nothing changed in the AI answers.

At Otterly, an add-on engine joins the pool for all prompts. Adding Claude also mixes one API-collected engine into a pool of answers read from consumer apps. Otterly's rule on AI Overviews also applies here: days without an Overview drop out of the percentage.

At Peec, engines are set per project. Two projects can therefore average different engines, and so can one project before and after a change. Peec's charts mark model changes with vertical markers. Its API also offers "model channels", stable identifiers for an AI surface that stay constant when the underlying model is upgraded.

**What this means:** a Peec Visibility score and an Otterly Brand Coverage score are not comparable levels. They come closer only when both are limited to the same engines.

Once the engines are settled, a few smaller differences remain.

## What else differs once the engines are set?

*Other plan terms, from each vendor's pricing page and help docs, 15 October 2026. Country limits on both sides need confirming in writing.*

| Criterion | Otterly.AI | Peec AI |
|---|---|---|
| Countries | Country fixed when a prompt is created; pricing page says "50+", help centre says "70+" | Plan table lists 1 on Starter, 3 on Pro and Advanced, unlimited on Enterprise; Advanced card also says "Multi country"; FAQ says any supported country at no extra cost |
| API and MCP | API and MCP access from Standard | MCP listed; API on Enterprise |
| Free trial | 7 days, 50 prompts, no credit card | "Start free trial" button; terms not documented |

MCP, the Model Context Protocol, lets an AI assistant read data from another tool. Peec's pricing page does not say whether its country limit applies per project or per account, or how it fits the FAQ.

## Which fits whom, and what to check before buying?

Otterly fits a team whose buyers use Perplexity and Copilot and that wants the same four engines on every prompt. The cost of that approach is that you pay for all four, and any extra engine is added to every prompt.

Peec fits a team that wants Gemini or AI Mode without add-ons, tracks Naver in South Korea, or needs different engines for different projects. The cost of that approach is that you choose engines up front. Changing them later shifts the average, so a project's trend before and after the change is not like for like.

Before buying, ask each vendor in writing:

- Which engines does each plan include, and can any included engine be switched off?
- Does an add-on engine apply to one project or to all of them?
- How does adding or removing an engine affect historical charts and reports?
- Can every metric and export be filtered by engine?
- How do country limits work, and do extra countries use prompt slots?
- If you need Claude, which model is tested, and on which plan?
