Otterly.AI vs SpyFu in 2026: AI-answer visibility monitoring vs SEO and PPC competitor research
Otterly.AI records brand visibility, answer position, citations, and GEO audit findings across four base AI engines from $29 monthly. SpyFu investigates competitors’ Google SEO and PPC history, keyword gaps, backlinks, rank movement, and reports from $39 monthly.
Otterly.AI
SpyFu- Otterly.AI Lite is $29 per month for four base AI engines, 15 prompts, one workspace, GEO audit, and citation-link analysis.
- Otterly.AI covers ChatGPT, Google AI Overviews, Google AI Mode, Perplexity, Microsoft Copilot, Claude, and Gemini, with more engines available as paid add-ons.
- SpyFu Basic is $39 per month for historical SEO and PPC competitor research and weekly rank tracking.
- SpyFu Pro + AI costs $119 monthly and adds API access, white-label reports, AI-powered recommendations, and 15-minute rank tracking.
- Otterly.AI includes a GEO audit and citation-link analysis on every listed tier, while API and MCP integration begin on Standard at $189 monthly.
- SpyFu has no AI model tracking, and Otterly.AI is not a documented replacement for historical PPC, organic keyword-gap, or backlink research.
Otterly.AI and SpyFu both help a marketer understand a competitive search landscape, but they observe different surfaces. Otterly asks whether a brand appears in monitored AI answers, where it appears, and which domains those answers cite. SpyFu asks which organic and paid Google keywords a competitor pursues, which PPC ads it has used, and how rankings and backlinks have changed. Choose Otterly for a GEO programme that needs answer-level evidence and recommendations. Choose SpyFu for search-marketing planning, historical PPC research, rank tracking, and agency reports. Neither turns a correlation into a conversion claim. An Otterly mention does not prove an AI answer drove revenue, and SpyFu’s competitive signals and estimated spend are not a rival’s account ledger. The tools can complement each other, but buying one instead of the other leaves a real blind spot if you need both AI-answer and Google-search evidence.
The tools at a glance
Otterly.AI
AI search visibility monitoring with answer position, cited-domain analysis, GEO audits, and optional API and MCP workflows
Otterly.AI is built for monitoring how a brand appears in AI-generated answers rather than studying a competitor’s Google keyword history. It tracks brand mentions across ChatGPT, Google AI Overviews, Google AI Mode, Perplexity, Microsoft Copilot, Claude, and Gemini. The product’s four base engines are supplemented by paid add-ons, so an evaluation should confirm the exact coverage required rather than treating every named engine as included at the Lite price.
Its meaningful features are answer and citation evidence. Otterly records whether a brand is present, where it appears in an answer, and which domains AI engines cite for category questions. The GEO audit adds recommendations intended to identify content and structural gaps. Those signals are useful for deciding what to investigate or improve, but they do not establish an exact traffic volume or financial return. Standard and Premium add API access and MCP integration, which gives an operations team a way to bring visibility data into an agent-assisted workflow.
Lite costs $29 monthly and includes 15 prompts and one workspace. Standard is $189, Premium is $489, and Enterprise begins from €1,000 monthly. There is no free tier, and white-label delivery is listed as contact-only on Enterprise. Otterly is the clearer purchase for SEO or content teams that need direct evidence about AI-answer visibility. It is not the right replacement for the historical PPC, backlink, and keyword-gap work that SpyFu covers.

SpyFu
SEO and PPC competitor intelligence with historical ad data, keyword gaps, 15-minute rank updates, API access, and branded reports
SpyFu is a Google-search research platform rather than an AI-answer monitor. It shows a domain’s organic keywords, paid keywords, historical ads, estimated activity signals, keyword overlap, gaps, ranking history, and backlinks. This is useful for a marketer entering a search market or trying to understand why a competitor’s conventional organic and PPC footprint differs from its own.
The platform pairs this research with rank tracking and reporting. Basic updates rankings weekly; Pro + AI and Team or Agency offer 15-minute updates. Pro + AI adds API access, white-label reports, and AI-powered recommendations based on the platform’s data. Historical records help form a search strategy, but the profile does not claim that they show a competitor’s actual cost, conversion rate, or profitability. SpyFu also does not track visibility inside AI-generated answers or referrals from AI models.
Basic is $39 monthly for one user. Pro + AI is $119 monthly for one user, and Team or Agency is $249 monthly for five users. It is the better buy for an SEO consultant or paid-search team that needs a practical competitor research workbench and client reporting. It cannot replace Otterly’s prompt-and-answer evidence, GEO audit, or citation analysis, so teams should keep the two research questions separate.
| Feature | Basic $39/month | Pro + AI $119/month | Team/Agency $249/month |
|---|---|---|---|
| API access | ✗ | ✓ | ✓ |
| White-label reports | ✗ | ✓ | ✓ |
| Rank tracking updates | Weekly | 15 min | 15 min |
| Users | 1 | 1 | 5 |
| AI-powered recommendations | ✗ | ✓ | ✓ |
| AI model tracking | ✗ | ✗ | ✗ |

Which should you choose?
Otterly.AIOtterly.AISpyFuSpyFuOtterly.AIThe decision is not really between two versions of competitor intelligence. Otterly measures the answer surface where an AI model may mention or cite a brand, then offers audit guidance. SpyFu measures the Google search and PPC footprint around a competing domain. A content team working on GEO should begin with Otterly because conventional ranking data cannot reveal an AI answer’s citations. A search team planning PPC and SEO activity should begin with SpyFu because a list of AI mentions cannot replace keyword or ad history.
Bottom line
Choose Otterly.AI for prompt-level AI visibility, answer position, cited-domain evidence, and GEO audit recommendations. Lite is the entry point, while Standard is necessary when API or MCP access is part of the workflow. Choose SpyFu for a lower-cost search and PPC competitor workbench with historical ads, keyword gaps, backlinks, fast rank updates, and agency reports from Pro + AI. Use both only when the organisation will act on both data sets, and do not turn either tool’s signals into unverified revenue claims.
Frequently asked questions
Is Otterly.AI or SpyFu better for finding out whether ChatGPT cites my company?
Otterly.AI is better for finding out whether ChatGPT cites your company because it is designed for monitored AI-answer visibility, answer position, and cited-domain analysis. SpyFu does not track AI model visibility and instead focuses on Google SEO and PPC competitor data.
Can SpyFu show the Google keywords a competitor uses while Otterly.AI cannot?
SpyFu can show a competitor’s organic and paid Google keyword history, overlap, gaps, and related ranking data because that is its core research workflow. Otterly.AI is designed to monitor AI answers and citations, so it should not be treated as a substitute for SpyFu’s conventional keyword research.
Which Otterly.AI plan includes API and MCP access for an agency workflow?
Otterly.AI Standard is the first listed plan with API access and MCP integration, and it costs $189 per month. Lite costs $29 per month but does not include either workflow feature, while Premium and Enterprise also include them. Confirm the prompt and engine configuration before selecting a tier.
Does SpyFu offer white-label client reports for SEO and PPC work?
SpyFu provides white-label branded reports from Pro + AI at $119 per month and Team or Agency at $249 per month. Basic at $39 per month does not include white-label reports or API access, so an agency should plan from Pro + AI rather than the entry tier.
Should a B2B content team replace SpyFu with Otterly.AI for GEO work?
A B2B content team should use Otterly.AI for GEO work when it needs direct evidence about AI answers, citations, and audit recommendations, but it should not assume Otterly replaces SpyFu’s Google keyword and PPC history. The two tools answer different questions and can be used together when both questions affect the plan.
