AEOeye vs Nightwatch: AI Visibility Tracking Compared (2026)

Nightwatch is an SEO rank tracker that added AI visibility tracking. Its homepage describes daily positions on Google, Bing, YouTube, DuckDuckGo and Yahoo, rank history stored since 2012, and checks from 107,000+ locations in 190+ countries.

The AI module sits inside that product, next to keyword research, a site audit, white-label reports and an SEO agent. Plans are priced by keywords tracked (500, 2,500 or 7,500), with AI prompts as a second allowance, per the pricing page. That shape suits an SEO team and fits badly if you only want AI answers.

When we checked Nightwatch's own site for AEOeye's crawler access study on 3 October 2026, its robots.txt blocked none of the AI crawlers we tested and named none, and /llms.txt returned a 404. The served homepage HTML carried FAQPage, SoftwareApplication, Offer and AggregateRating schema but no Organization type (schema injected by JavaScript would not show in our fetch). That is a fact box, not a verdict on the product.

Nightwatch asks AI platforms the prompts you supply, on a schedule, and reports whether and where your brand appears. Per its help docs, each prompt gets a provider, country and language, and results list detected brands, position, sentiment and cited domains. The default refresh is daily.

Dashboards cover visibility, share of voice, sentiment, cited sources and a Source Matrix that the docs label beta. Nightwatch's AI share-of-voice guide defines share of voice as your brand mentions divided by all brand mentions across tracked prompts. The idea comes from advertising, where share of voice measures one company's slice of category spending.

The headline feature is Citation Intelligence, which joins ranking changes to AI citation changes. Its premise, stated on the AI tracking page, is that ChatGPT, Claude, Gemini and Perplexity cite what ranks on Google. We think that is half true. Nightwatch's own blog says the overlap is real but "not a direct one-to-one relationship", and that ChatGPT and Perplexity regularly surface lower-ranking pages.

Google says AI Overviews and AI Mode may use query fan-out and show a wider, more diverse set of links than classic search. A University of Toronto study found AI search leans heavily toward earned media over brand-owned content. So the rank-to-citation link is most useful for Google's own AI surfaces; for ChatGPT or Claude recommendations, whether third-party sources name you matters at least as much.

They answer different questions. Nightwatch monitors a fixed prompt set every day inside an SEO subscription. AEOeye runs a one-time audit of the questions buyers ask and shows the real answers. AEOeye is not a daily tracker and does not pretend to be.

• Free start: AEOeye's free audit asks ChatGPT three unbranded buyer questions live and shows the answers in full, plus the competitors AI recommends instead. Nightwatch offers a 14-day trial on every plan.
• Engines: the $29 AEOeye full report adds Claude, Gemini, Google AI and Perplexity and ten questions, each engine at the default tier a free user sees. Nightwatch's engine list varies by page (see below).
• Price basis: AEOeye is $0 or $29 once, with no subscription. Nightwatch starts at €99 a month (€79 billed yearly) as of October 2026.
• Setup: AEOeye needs a brand name. Nightwatch needs a domain, keywords and a prompt list.

Nightwatch's own pages disagree on engines. The pricing page lists ChatGPT, Claude, Gemini, Perplexity, AI Mode and AI Overview on every plan. The AI tracking page's FAQ names Microsoft Copilot and does not mention AI Mode or AI Overview, and a help article dated 27 February 2026 omits Claude and reserves Gemini for plans with 300+ prompts. Confirm in the trial what your plan runs.

It is enough when rank tracking is already a paid, ongoing job. Then AI prompts come inside the plan, there are no per-seat fees, and Citation Intelligence puts rankings and AI answers in one report. For agencies that is a real saving over a second subscription.

On the pricing page, Starter includes 50 AI prompts, Professional 150 and Agency 500, with white-label reports and Looker Studio from Professional. Monthly billing is €99, €199 and €499; yearly billing brings those to €79, €159 and €399 a month. Older write-ups, including an earlier version of this page, described a separate AI add-on of about $99 a month. The current pricing page shows none, so treat that figure as outdated.

For a price-and-value view, see is Nightwatch AI tracking worth the price.

You need one when AI answers are the whole job: many prompts, many engines, and enough repeat runs to trust the numbers. That is where Nightwatch's allowance is thinnest, because answers vary from run to run.

SparkToro, working with Gumshoe.ai, had 600 volunteers run 12 prompts through ChatGPT, Claude and Google's AI a combined 2,961 times in late 2025. There was under a 1 in 100 chance of the same brand list twice from ChatGPT or Google's AI. They suggest 60 to 100 runs per prompt and treat visibility percentage, not position, as the usable metric.

Nightwatch's Starter plan allows 1,500 AI answers a month for 50 prompts, which is our arithmetic for 30 per prompt. Because the docs set one provider per prompt, we read that as one engine, once a day. Check whether a prompt counts once per engine before you budget.

Peec defines monthly answers as prompts times active models times frequency. Entry prices per prompt sit in the same range across these tools; the difference is sampling depth. Compare options in our AI visibility tracker roundup and best AI visibility tools.

Choose by the job you have today, not by the logo. Run a snapshot first if you have never seen what AI says about you, because the snapshot tells you whether you have a presence problem or a measurement problem.

1. You already pay for rank tracking, or run an agency: start Nightwatch's trial. Test Citation Intelligence on keywords you rank for, and check the engines and answers per prompt.
2. You need to know today whether AI names you: run the free AEOeye audit, then the $29 report for five engines and ten questions. No subscription.
3. You need hundreds of prompts and deep sampling: use a dedicated tracker, or see the Nightwatch alternatives.

Many teams do 2 then 1: snapshot first, then a monitoring subscription once the numbers justify it.
