AEOeye vs Otterly.ai: An Honest Head-to-Head (2026)

The cleanest way to think about it: AEOeye answers "where do I stand today?" for free, and Otterly.ai answers "how is my position changing over time?" for a monthly fee.

AEOeye runs a blind, multi-engine audit on demand. You enter a brand and questions, and it queries ChatGPT, Perplexity, Google AI, Claude and Gemini together, then shows whether each engine recommends you, where you rank, and which competitors come up instead. There's no trial countdown and no contract — you can run a check before deciding anything.

Otterly.ai is a monitoring platform. You set up a list of tracked prompts, and it re-runs them on a schedule (daily on paid plans), building history, share-of-voice charts, citation tracking and page-level GEO audits over time. That recurring structure is its real value — and the reason it's a paid subscription rather than a free tool.

Neither model is "better" in the abstract. If you need a fast read or you're not ready to commit budget, the free audit wins. If you need a documented trend line for a team or client, the monitoring platform earns its keep.

Headline numbers can mislead here, so it's worth being precise. AEOeye queries ChatGPT, Perplexity, Google AI, Claude and Gemini as part of its standard audit — there are no per-engine upgrade fees to unlock any of them.

Otterly.ai's base plans (Lite, Standard, Premium) track four engines by default: ChatGPT, Google AI Overviews, Perplexity and Microsoft Copilot. Gemini, Google AI Mode and Claude are paid add-ons layered on top of your plan — roughly $9 to $149/month each depending on tier, and Claude's add-on can run higher on larger plans. Notably, Otterly covers Microsoft Copilot in its base tier, which AEOeye does not query today.

So the comparison isn't simply "more engines vs fewer." Otterly can cover a broader set including Copilot, but only its first four come without extra cost; full coverage means stacking add-ons, and a $189/month plan can climb past $300 before every engine is on. AEOeye's five engines are included from the first free run, with Copilot the notable gap. Match the list against the engines your buyers actually use before deciding which breadth matters.

AEOeye is free to start with no contract and no trial clock — you can run an audit without entering payment details or committing to a term.

Otterly.ai has no free-forever plan. It offers a 14-day free trial, then three tiers: Lite at $29/month (about 15 tracked prompts), Standard at $189/month (100 prompts) and Premium at $489/month (400 prompts). Annual billing saves roughly 15%.

The pricing gap most reviewers flag is the jump from Lite to Standard. Fifteen prompts on the $29 plan is enough to dabble but, by many accounts, too few to run a serious monitoring program — and the next step up is a roughly 6x leap to $189 with nothing in between. Extra prompt packs run about $99/month each, and engine add-ons stack on top, so real-world costs can scale faster than the headline price suggests.

That said, Otterly's higher tiers buy real infrastructure: API access, an MCP server, a Looker Studio connector and large audit allowances. If you'll use those, the price reflects genuine capability rather than markup.

Being fair means naming Otterly's real advantages, because there are several.

First, longitudinal data. Otterly's scheduled daily tracking builds the historical trend lines, share-of-voice over time and citation history that a one-shot audit can't produce. If you need to prove movement to a client or the board, that history is the deliverable.

Second, integrations and scale. The Standard and Premium tiers include an API, an MCP server and a Looker Studio connector, plus large audit and request allowances. That makes Otterly a better fit for agencies wiring AI-visibility data into existing dashboards and reporting workflows.

Third, page-level GEO audits and Copilot coverage in the base plan. Otterly's GEO Audit inspects individual pages for citation-readiness, and Copilot is included without an add-on.

AEOeye is newer and lighter on enterprise analytics and historical dashboards — its deeper multi-engine querying activates with usage rather than arriving fully built out on day one. If mature reporting is your priority today, Otterly is the safer pick.

One recurring critique of monitoring-first tools is that they tell you where you stand without telling you what to do next. As one Reddit reviewer put it about Otterly, it "tracks the source but gives zero actionable strategy on how to restructure content to get cited." Its GEO Audit flags issues, but reviewers note it stops short of step-by-step fixes, and it doesn't tie AI mentions to traffic or conversions — so the loop from visibility to revenue stays open.

AEOeye's blind, side-by-side engine results are designed to make the gap obvious fast: you can see exactly which competitor an engine names instead of you, and on which questions, which points toward what to fix first. It's worth being honest that AEOeye is also primarily a diagnostic — neither tool is a full content-production or attribution suite, and you'll still bring your own GEO strategy to either one.

The practical takeaway: if your team already knows what to do with a visibility gap and needs ongoing measurement, Otterly's tracking is valuable. If you mainly need to see the gap clearly and cheaply right now, start with AEOeye's free audit.
