otterly pricing
Otterly sells three self-serve plans: Lite at $29 a month for 15 prompts, Standard at $189 for 100, and Premium at $489 for 400, each about 15% cheaper billed annually. Standard is the tier compared here, since 15 prompts is not a comparison. It adds API access, MCP access, and Agent Analytics, and extra prompts are $99 per hundred.
Every plan includes the same four engines: ChatGPT, Google AI Overviews, Perplexity, and Microsoft Copilot. Claude, Gemini, and Google AI Mode are sold separately, priced by tier. Enterprise starts from $1,000 a month.
Against that, Centium is one price: $99 a month billed annually buys 120 prompts, six models, 720 responses per refresh, unlimited seats, and export, with no engine sold separately. The ranked comparison of eight AI visibility platforms covers the rest of the field, and Centium’s pricing page has the three cadences.
included or an add-on
Otterly’s four included engines are a reasonable starting set, and its unlimited seats and daily tracking are both genuinely good. The question is what happens when your buyers are somewhere else.
Claude is $109 a month on Standard. Gemini is $59. Google AI Mode, which Otterly bills separately from AI Overviews, is another $59. Adding all three costs $416 a month, or about $353 billed annually, and buys five of Centium’s six models on 100 prompts. Grok is not sold at any price, so the sixth is out of reach.
Centium is $99 a month for all six, on 120 prompts, with no engine to unlock. Four engines against six is the whole gap: every Centium reading is 720 AI responses against 400, 80% more each time you measure. AI models are non-deterministic, and a wider sample is the only thing that separates a real position from noise. Otterly refreshes daily and Centium does not, so this is a comparison of how much each reading sees, not how much arrives in a month.
Query fan-out, AI crawler access, export, and the full archive ship with every Centium plan. Cadence is the only choice you make.
- You want measurement depth: 720 AI responses in every reading against Otterly’s 400, 80% more each time you measure.
- Your buyers use Claude, Gemini, or Google AI Mode, and you would rather not pay per engine for them.
- You want a fixed price for complete coverage instead of a base plan plus add-ons.
- Grok matters to your category. Otterly does not sell it at any tier.
- You want to see which publications and pages a model cited, not only how often your name came up.
- You need API or MCP access. Otterly includes both on Standard; Centium gets your data out through exports instead.
- Microsoft Copilot is part of how your buyers search. Centium does not cover it.
- A number every morning matters more to you than how much sits behind each one.
centium or otterly.
Otterly Standard is $160 a month billed annually for 100 prompts across four AI engines: ChatGPT, Google AI Overviews, Perplexity, and Microsoft Copilot. Claude, Gemini, and Google AI Mode are paid add-ons on top. Centium is $99 for 120 prompts across all six of its models with nothing to add, which is 720 AI responses in every reading against 400, 80% more each time. Otterly refreshes daily, so that is a comparison per reading rather than per month.
Otterly Lite is $29 per month for 15 prompts, Standard is $189 for 100, and Premium is $489 for 400, each about 15% cheaper billed annually. Standard adds API access, MCP access, and Agent Analytics. Extra prompts are $99 per 100 per month. Enterprise starts from $1,000 a month.
Only as paid add-ons. On the Standard plan they are billed monthly at $109 for Claude, $59 for Gemini, and $59 for Google AI Mode, or $1,100, $610, and $610 a year. Grok is not offered at any tier. Centium includes ChatGPT, Claude, Gemini, Google AI Mode, Perplexity, and Grok on every plan at no extra cost.
Adding Claude, Gemini, and Google AI Mode to Otterly Standard costs $416 a month, or about $353 a month billed annually. That buys five of Centium’s six models on 100 prompts, since Grok is not available. Centium is $99 a month billed annually for all six on 120 prompts.
No. Otterly Standard is $160 per month billed annually against Centium at $99, and $189 against $119 month to month. Otterly Lite is cheaper at $29, but covers 15 prompts rather than 120.
Centium, if you want every model included rather than metered. It runs six AI models on 120 prompts for $99 a month with no per-engine add-ons, where matching that coverage on Otterly Standard runs to $416 a month and still leaves out Grok. If you need API or MCP access, Otterly Standard has both, where Centium gets your data out through CSV and XLSX exports instead.
