AEOeye vs Otterly.AI: Which Should You Use? (2026)

Choose AEOeye if you have not yet checked whether AI engines name you. Choose Otterly.AI if you already have a fixed list of buyer questions and need the answers refreshed daily, with history, exports and an API. The real question is whether you need a snapshot or a trend line.

• AEOeye fits: a first look at your visibility, a quick check on a prospect or competitor, or a budget of $29 once rather than a monthly bill.
• Otterly.AI fits: a team with a prompt list that wants to watch it move, an agency reporting to clients, or anyone who needs the data in Looker Studio or an API.

Our view: paying monthly to track a gap you have never measured is paying to watch. Spend the first hour on a snapshot, then decide whether the gap deserves a subscription.

The reverse also holds. Once an audit shows you are absent and you start fixing it, a one-off report cannot tell you whether the fix worked. That is the moment a tracker earns its fee.

AEOeye is a one-off audit; Otterly.AI is a monitor you subscribe to. AEOeye runs your buyer questions once and returns a report, while Otterly.AI re-runs a saved prompt set every day and charts what changes.

AEOeye. The free audit asks ChatGPT three unbranded buyer questions live. It shows the full answers, the competitors ChatGPT recommends instead, and starter fixes. The $29 one-time report adds Claude, Gemini, Google AI and Perplexity, grows to ten questions (the free three are kept), and adds a five-layer SEO foundation audit and a fix roadmap, with a PDF emailed to you. Each engine is tested at the default tier a free user would get. There is no subscription, and AEOeye is not a daily tracker.

Otterly.AI. According to its help center, you define prompts and it queries the engines for you every day. You then see whether your brand was mentioned, whether your site was cited and how you compare with competitors. Each prompt is tied to one country, so the same question in the US and the UK takes two prompt slots, per its prompt-limit guide.

They differ on how you pay, how often answers refresh and how you get the data out. The full table follows the sections; these four differences decide most purchases.

• Payment. AEOeye is a free audit, then $29 once. Otterly.AI charges $29, $189 or $489 a month for 15, 100 or 400 prompts, or $25, $160 and $422 a month billed annually. Prices are US dollars before tax, as of October 3, 2026; Enterprise is custom-priced from 1,000 prompts.
• Refresh. AEOeye gives one snapshot per audit. Otterly.AI runs every prompt daily, and you cannot trigger a run or change the frequency.
• Data access. AEOeye delivers a report and an emailed PDF. Otterly.AI offers CSV, JSON and PDF exports on all plans, per its export guide, and the Looker Studio connector from Standard up.
• Collection. Otterly.AI says it reads engines through their public web interfaces, using an API only for Claude. AEOeye tests each engine at the default free-user tier.

Otterly.AI also offers a 7-day free trial with no credit card and 50 prompts, over three times Lite's 15.

Otterly.AI is stronger wherever repetition matters: daily runs, history, exports, team reporting and integrations. A one-off audit cannot do any of these, and AEOeye does not try to.

Repetition is the strongest argument. In a SparkToro study, 600 volunteers ran 12 prompts 2,961 times across ChatGPT, Claude and Google's AI. There was under a 1 in 100 chance that ChatGPT or Google's AI would give the same brand list in any two responses. Otterly.AI's help center makes the same point: AI responses are not deterministic, and daily checks build the sample you need to see a signal. One audit answer is a screening result, not a measurement.

More advantages:

• History. Tracking starts when a prompt is created, with no backfill. A trend line exists only for the days you tracked, so starting sooner is the point.
• Integrations. API access, MCP access and the Looker Studio connector come with Standard and above; Standard allows 2,000 API requests a month.
• Engine coverage. Microsoft Copilot is in every plan. AEOeye does not test Copilot.
• Agencies. Standard and above include unlimited workspaces, and Agency Partner status raises Standard to 150 prompts.

An older criticism says Otterly.AI only monitors and never tells you what to fix. Its current pricing page lists Recommendations (three a week on Lite, unlimited above) and a GEO Audit, so do not rule it out on fixes.

AEOeye is stronger when you want an answer this hour without a subscription. For $29 once you get five engines; covering the same five on Otterly.AI costs $67 to $357 a month, because Claude and Gemini are paid add-ons.

The comparison is rough. Otterly.AI tracks 15 or 100 prompts daily, AEOeye asks ten questions once, and Google AI Overviews is only the closest match to AEOeye's Google AI. Still, for a first answer the gap is large.

Three other strengths:

• Nothing to cancel. The free audit and the $29 report are one-time. Otterly.AI says that after you cancel, tracked data and historical data are deleted, so export first.
• Default-tier testing. We test each engine as a free user would meet it, not with a stronger model than your buyers see.
• A starting point for fixes. The free audit names the competitors the engine recommends instead, and the report adds a fix roadmap.

What AEOeye does not do: daily runs, history, dashboards, or any guarantee that engines will recommend you.

In AEOeye's crawler access study (October 2026, 391 sites), our research crawler received HTTP 403 from otterly.ai for robots.txt, /llms.txt and the homepage. So we could read nothing about its AI-crawler policy or schema. That was one fetch on one day, most likely a bot challenge, and it says nothing about the product.

For comparison, aeoeye.com blocks no AI bot in robots.txt, names six of them explicitly, publishes an llms.txt and serves Organization, SoftwareApplication, Offer and FAQPage markup on its homepage. The per-site rows are in the study's CSV, and the method is on our AI crawler directory.

Run the free AEOeye audit first, then start Otterly.AI's trial with the same questions. Both cost nothing to try, and the comparison takes under an hour.

1. Write ten buyer questions that do not contain your brand name.
2. Run the free audit on three of them. Read the full ChatGPT answers and note who is named instead of you.
3. If you are absent, decide whether the $29 report's five engines are worth it.
4. Start Otterly.AI's trial and enter the same questions, one prompt per country you sell in.
5. Check the same prompts across several days. If the brand list keeps changing, you need a tracker; if it is stable and empty, you need fixes first.
6. Before paying Otterly.AI, read the pricing guide for add-on totals and our review for features beyond price.
