AdSpy vs Otterly.AI in 2026: Meta ad research vs AI search visibility monitoring
AdSpy searches Facebook and Instagram advertising with filters for creative, comments, demographics, affiliates, and landing-page technologies. Otterly.AI tracks a brand’s appearance and citations across AI search engines from $29 per month.
AdSpy
Otterly.AI- AdSpy publishes a Facebook and Instagram archive of more than 213 million ads, with filters across 225 countries and 88 languages.
- AdSpy’s differentiators are public-comment, affiliate-network, affiliate-ID, Offer ID, and landing-page-technology searches.
- AdSpy publishes one $149-per-month subscription with virtually unlimited use, but no public API or integrations in the reviewed profile.
- Otterly.AI tracks ChatGPT, Google AI Overviews, Google AI Mode, Perplexity, Copilot, Claude, and Gemini, with four base engines and add-ons by plan.
- Otterly Lite is $29 monthly for 15 prompts, while API and MCP integration start on Standard at $189 monthly.
- Otterly’s GEO audit and citation analysis are optimization inputs, not a competitor’s paid-social creative archive.
These tools should not be treated as substitutes. AdSpy is a research database for visible Facebook and Instagram ads. Otterly.AI is a GEO monitoring product that checks brand visibility, answer position, citations, and cited domains across AI search engines. AdSpy costs $149 per month for virtually unlimited use as published, which makes sense only if its specialist Meta filters regularly shorten real investigation work. Otterly starts at $29 per month for 15 prompts across four base engines, but API and MCP access begin at Standard for $189 per month. Choose AdSpy when the question is how an affiliate, competitor, or offer is presented in Meta advertising. Choose Otterly when the question is whether AI answers cite or rank your brand and what gaps a GEO audit identifies. Neither reveals private ad spend, conversions, or profitability.
The tools at a glance
AdSpy
Facebook and Instagram ad database with deep creative, comment, demographic, and affiliate filters
AdSpy is narrowly built for Facebook and Instagram advertising research. The company describes a searchable archive of more than 213 million ads, 30 million advertisers, 225 countries, and 88 languages. A researcher can begin with ad text, advertiser name, or URL, then narrow visible ads by reactions, media type, last-seen activity, and longevity. Its purpose is to find patterns in public creative and offers, not to operate an ad account or report a brand’s campaign outcomes.
The specialist filters are why some researchers will choose it over a broader library. AdSpy publishes public-comment search, location, gender, age-range, affiliate-network, affiliate-ID, Offer ID, and landing-page-technology fields. An affiliate marketer can investigate an Offer ID, trace how it is being positioned, inspect visible public feedback, and study the landing-page route. Those signals are useful for forming an original creative or offer hypothesis. They do not expose audience settings, paid conversions, revenue, margin, or the advertiser’s actual return.
The public commercial offer is simple: virtually unlimited use for $149 monthly, with a stated full refund within 24 hours. That price is defensible for repeat Meta investigations, but hard to justify as a general marketing dashboard. The reviewed pages do not establish team controls, a reporting layer, API access, or integrations. Choose it for recurring Facebook and Instagram intelligence where its filters matter, not for AI-search rank monitoring or a broad paid-media operations stack.

Otterly.AI
AI visibility monitoring with GEO audits, citation analysis, API, and MCP support
Otterly.AI answers a different kind of competitive question: whether your brand appears in AI-generated answers and which domains those answers cite. It monitors ChatGPT, Google AI Overviews, Google AI Mode, Perplexity, Microsoft Copilot, Claude, and Gemini. Plans include four base AI engines, with Gemini, Google AI Mode, and Claude available as paid add-ons in the reviewed profile. This is monitoring for generative search, not a catalog of paid Meta creative.
The product adds a GEO audit, domain ranking, citation-link analysis, and answer-ranking monitoring. That lets a team see not only whether it appears, but where it sits in an answer and which competitor domains are earning citations. The audit produces optimization recommendations intended to improve AI-search visibility. Those recommendations are useful inputs for content and technical decisions, although they do not prove that a change will improve a commercial result or explain a competitor’s Facebook and Instagram targeting choices.
Lite costs $29 monthly for 15 prompts and one workspace. It is a sensible monitoring entry point for a solo marketer or small in-house team, but it does not include API access or MCP integration. Standard is $189 monthly and Premium is $489, both with API and MCP access; Enterprise begins from €1,000 monthly. Otterly is the better fit when a repeatable AI-visibility programme is required, while AdSpy remains the better specialist tool for Meta offer research.

Which should you choose?
AdSpyAdSpyAdSpyOtterly.AIOtterly.AIAdSpy is a specialist research purchase and Otterly.AI is an ongoing monitoring purchase. AdSpy earns its higher entry price only when an analyst repeatedly needs its Meta-specific investigation fields. Otterly earns its place when AI-generated answers have become a visibility channel that a team needs to measure over time. A company running both Meta acquisition and AI-search content may use both products, but their outputs should never be conflated: visible paid ads are not citation data, and a cited domain is not evidence of a profitable Facebook campaign.
Bottom line
Choose AdSpy for deep Facebook and Instagram offer research, particularly when comment, affiliate, Offer ID, demographic, or landing-page filters will be used regularly. Choose Otterly.AI for multi-engine AI visibility tracking, GEO audits, answer ranking, and citation intelligence, starting at $29 monthly if 15 prompts and dashboard access are sufficient. Upgrade to Standard only when API or MCP workflows are needed. Neither product replaces campaign reporting from your own ad accounts.
Frequently asked questions
Is AdSpy or Otterly.AI better for researching Facebook ads before launching an ecommerce offer?
AdSpy is the better choice for researching Facebook ads before an ecommerce offer launch because it is built around visible Meta creative, comments, affiliate fields, Offer IDs, and landing-page technologies. Otterly.AI tracks AI-answer visibility and citations, not Facebook or Instagram ad creative.
Can Otterly.AI tell me which competitor Facebook ad is driving the most sales?
Otterly.AI cannot tell you which competitor Facebook ad is driving the most sales because it monitors AI-search visibility, citations, and answer ranking rather than advertiser conversion or revenue data. AdSpy can reveal public Meta ad patterns, but it also cannot access a competitor’s private spend, sales, or margin.
Which AdSpy or Otterly plan includes API access for an agency workflow?
Otterly.AI Standard, Premium, and Enterprise include API access and MCP integration in the reviewed pricing table, while Otterly Lite does not. AdSpy’s reviewed public pages do not establish an API or agency reporting integration, so it should be treated as a research interface rather than a data source for automated reporting.
Is Otterly.AI Lite enough for a small team tracking ChatGPT and Google AI visibility?
Otterly.AI Lite is enough for a small team that needs dashboard monitoring of 15 prompts across four base AI engines and can work without API or MCP access. The reviewed profile lists additional engine add-ons separately, so confirm the exact engine mix before assuming Lite covers every Google or AI platform you need.
Can AdSpy or Otterly.AI prove that a competitor marketing tactic works?
Neither AdSpy nor Otterly.AI can prove that a competitor marketing tactic works because neither exposes the competitor’s private conversion, revenue, spend, or margin data. Use AdSpy to develop a Meta creative hypothesis and Otterly to identify AI-search gaps, then validate either decision with your own first-party performance data.
