- Otterly starts at $29/month with a 14-day trial; Optimus Pass offers a limited free snapshot with a verified account, plus a $199/month Professional plan for full diagnostics.
- Otterly tracks brand mentions across AI engines. Optimus Pass is built for a different job: the page conditions behind those mentions.
- The section below shows where each tool fits. Pick the one that matches the job you need done.
- Agencies can use both: Otterly for monitoring retainers and Optimus Pass for free prospect scans plus self-serve multi-client diagnostics.
The one-paragraph version
Otterly is an AI search monitoring platform used by marketing teams and agencies: you pick prompts, it runs them against ChatGPT, Google AI Overviews, Perplexity, and Copilot daily (Claude, Gemini, and Google AI Mode as paid add-ons), and reports brand presence, position, citations, and competitor share over time. Optimus Pass is a visibility and compliance diagnostic tool: it scans a URL you submit against 46 named on-page checks across SEO, GEO readiness, and AEO readiness, and separately scans ad copy against 65 risk detectors for 10 ad platforms. One reports what AI engines returned for tracked prompts. The other reviews observable page conditions and ad-copy risk signals; it does not verify future citations or ad approval.
Primary use case
Ongoing AI search visibility monitoring. You define search prompts, and Otterly tracks whether your brand appears in AI answers, in what position, with what sentiment, and which pages are cited - daily, over time, against competitors.
Page-level visibility diagnostics plus ad compliance. You submit a URL and get SEO (18 checks), GEO readiness (11 checks), and AEO Readiness - Beta (17 checks) findings, plus an ad-copy scanner with 65 risk detectors across 10 platform profiles.
How visibility is measured
Prompt execution against live engines. Four engines are included on every plan (ChatGPT, Google AI Overviews, Perplexity, Microsoft Copilot); Claude, Gemini, and Google AI Mode are paid add-ons. Metrics include a Brand Visibility Index, domain ranking, link-citation analysis, and agent analytics on Standard and above.
Static analysis of the page itself. The scan does not query AI engines; it evaluates on-page evidence - answer blocks, question headings, schema, author attribution, freshness, internal links, crawlability signals. Scores are 0-100 per dimension and are explicitly directional, not engine-verified.
Methodology and evidence transparency
Public pricing page lists plan contents in detail; product methodology is documented in its help center and blog, including GEO experiments. Engine sampling is live, so reported mentions reflect actual responses to your tracked prompts at run time.
The public methodology page (/methodology/visibility) documents each measured dimension, the evidence standard every finding carries, and what the diagnostics do and do not measure; each finding names the check it came from and states the evidence found, and the product states plainly that scores do not predict rankings, indexing, or citations. No engine-response claims are made, because none are measured.

What Optimus Pass does differently
- A limited free snapshot.Otterly's entry point is a 14-day trial of a subscription platform. Optimus Pass provides a one-page visibility snapshot after free account verification, with no credit card required.
- Named, checkable methodology. 46 named on-page checks (18 SEO, 11 GEO, 17 AEO Readiness - Beta) run on every page; the methodology page documents the measured dimensions and the evidence standard each finding carries, and each finding names its check and states the evidence it was based on. The product labels its scores as directional diagnostics and explicitly declines to promise rankings or citations.
- Compliance and visibility in one place.Teams running paid campaigns can scan ad copy against 10 platform risk profiles and audit the landing page's visibility readiness in the same workflow. Otterly does not offer ad-copy compliance scanning.
- A software workflow. Agency adds 250 monthly checks and multi-client organization to the self-serve diagnostic workflow.
What each tool is built to do
Otterly is built for ongoing monitoring. Optimus Pass is built for the page those engines read. The list below states what each side is built to do, so you can match it to the job you need done.
- Engine-response measurement. Otterly tracks mention rate, answer position, and citation share against live engines. That is its job. Our scope is the page.
- Longitudinal tracking. Otterly builds daily trend history across your prompt set and competitor set. Optimus Pass is a point-in-time analysis of one URL.
- API, MCP access, and reporting connectors. Otterly ships API and MCP access on Standard and above, plus a Looker Studio connector. Optimus Pass is a self-serve diagnostic.
- Scan volume. Otterly's GEO URL audits run at volume (1,000 to 10,000 per month depending on plan). Our free snapshot analyzes one page after account verification.
- Scale. Otterly is used by tens of thousands of marketing professionals, with named customer logos. Optimus Pass is a focused page-level diagnostic, and its agency workflow features are in Early Access.
Which fits your job
For the question “how often do AI engines mention my brand, where do we rank in their answers, and how does that move over time,” Otterly is built for that.
For the question “what observable page conditions should we review, and what risk patterns appear in this ad copy,” that is the job Optimus Pass is built for. Its findings do not predict rankings, citations, or ad approval.
Which should you choose?
Choose Otterlywhen the question is “how do we show up in AI answers over time, versus our competitors?” - ongoing multi-engine monitoring, prompt demand research, citation tracking, and client-ready reporting at agency scale.
Choose Optimus Passwhen the question is “what page conditions should we review, and what risk patterns appear in this ad copy?” - page-level diagnostics with named checks, a limited free snapshot after account verification, combined ad-compliance review, or a human-interpreted executive audit for a client.
Use both if you need the full loop: monitoring to detect visibility gaps, diagnostics to find and fix the on-page causes, monitoring again to confirm the change moved engine behavior.
