Otterly AI pricing, explained

The mistake is comparing Otterly AI pricing by the monthly number alone. A team sees Standard at $189, then finds that it includes 100 search prompts and that the next 100 cost $99. The first figure is easy to spot. The usage limit is where the bill starts doing its quiet work.

This is the Otterly pricing page as we read it on 2026-09-10, with the prices re-checked on 2 Oct 2026. We have turned each published plan into a cost per search prompt, so you can test the price against your workload rather than admire the plan names.

Published plans

Otterly labels the monthly view “Monthly” and the annual view “Annually 15% off” on its pricing page. The monthly prices are Lite at $29, Standard at $189 and Premium at $489. The annual prices shown are $25, $160 and $422. The page describes Lite as being for “solo marketers, and small teams”, Standard as being for “SMEs and small marketing teams”, and Premium as being for “mid-sized companies & agencies”.

There is also Enterprise. Otterly lists it as “Custom” and “Starting from 1,000 search prompts”, with no dollar figure.

The prompt counts come directly from the page: “15 search prompts”, “100 search prompts” and “400 search prompts”. Otterly also says it tracks four engines: ChatGPT, Google AI Overviews, Perplexity and MS Copilot. These figures describe different units, so the table is a pricing comparison, not a like-for-like product comparison.

The prompt allowance is the main constraint.

For context, CiteGraph's pricing page lists Starter at $29 a month, with two projects, 10 questions each, three runs per question on four engines, six tracked rivals and 30 written pages a month. Growth is $69, with three projects, 10 questions each on four engines, 10 tracked rivals and 60 written pages. ChatGPT Only is $19, with one project and 20 questions, asked on ChatGPT only. Weekly scans ask each question three times on every plan; a scan you start on Growth asks it five times. These products use different units, so this is context rather than a like-for-like price claim. Our weekly research on who owns AI answers uses a different measure again.

The comparison is useful only after you define the unit.

Prompt costs

The entry plan looks expensive per prompt because its allowance is small. Lite works out at $29 divided by 15, or about $1.93 per search prompt. Standard is $189 divided by 100, or $1.89. Premium is $489 divided by 400, or about $1.22. These are calculations from the prices and limits printed by Otterly, not a claim that every prompt produces equal research value.

Annual billing changes the unit cost.

Using the annual prices shown on the page, Lite is about $1.67 per prompt, Standard is $1.60 and Premium is about $1.06. Otterly presents these as monthly equivalents under its annual view, so they should not be read as separate monthly contract prices.

Otterly also says, “Add 100 extra search prompts at $99”. That add-on works out at $0.99 per extra prompt. The page says additional AI engines can be bought in fixed packages for up to 1,000 prompts, and that customers with more prompts should contact support. Those packages are priced per plan: on 2 Oct 2026, Google AI Mode and Gemini were $9, $59 and $149 a month each on Lite, Standard and Premium, and Claude was $29, $109 and $439 a month. The extra 100 prompts are not available on Lite.

The four named engines are the only engines included in this public comparison.

Worked buying example

Suppose you need 100 search prompts each month and want the four engines Otterly names. Standard is the first published tier whose allowance reaches that workload. Start with the monthly price: $189. Divide by the allowance: $189 ÷ 100 = $1.89 per search prompt. Then divide by four engines: $1.89 ÷ 4 = about $0.47 per engine.

That is the monthly calculation.

On annual billing, the displayed monthly equivalent is $160. The same line by line calculation is: $160 ÷ 100 = $1.60 per prompt, then $1.60 ÷ 4 = $0.40 per engine. This uses the annual monthly equivalent shown on the page.

Annual billing gives the same workload a lower displayed unit cost.

Lite provides 15 prompts, so it does not cover a workload of 100. Premium provides 400 prompts, so it covers that workload with unused capacity if demand stays at 100. Enterprise is listed as custom, starting from 1,000 search prompts, with no published price.

A lower unit price can still leave you with unused capacity.

Count the questions you need to track, decide how often each one runs, and multiply that work before opening the checkout page. Otterly's public pricing does not explain whether a prompt means one question across all four engines, or how repeated runs are counted, so we do not assign an extra run cost.

Your workload comes before the plan name.

Limits of the data

This page compares prices, not output quality or citation accuracy. Nothing here tells you how Otterly performs in independent reviews. We can calculate the published cost per prompt, but we cannot tell you how useful each result will be.

Price is not a performance test.

Otterly does not publish an Enterprise price. It also does not explain how the public prompt count maps to repeated runs and question variants, so the figures above should be treated as a pricing comparison, not a complete usage forecast.

Some of the bill remains unknown.

Our data has a clear limit: we measured the published pricing sample on one reading date, not every possible contract or billing configuration. We measure samples; we print margins; we do not know what we have not measured.

Do these three things this week:

1. Count the search prompts you need in a normal month, including repeated checks.
2. Calculate your monthly and annual cost per prompt, then mark any unused allowance.
3. Add the published price of any extra engine package you need before treating four engines as your full monitoring cost.
