What is the difference between TrustData and Otterly.ai?

Otterly.ai is a standalone AI visibility monitoring tool that tracks brand mentions across AI search engines. TrustData is a full marketing analytics platform that includes AI visibility monitoring in every plan, alongside multi-touch attribution, budget optimization, anomaly detection, and incrementality testing. Otterly answers 'where does my brand appear in AI search?' TrustData answers that plus 'which channels drive revenue and where should I spend next?'

Is TrustData cheaper than Otterly for AI visibility?

It depends on what you need. Otterly's Lite plan starts at EUR 29/month with 15 prompts, which is cheaper if you only want basic AI monitoring. But TrustData's Track plan at EUR 49/month includes 1,000 AI probes plus first-party tracking, attribution, and alerts. If you need both AI visibility and marketing analytics, TrustData is significantly more cost-effective than running Otterly alongside a separate attribution tool.

Does Otterly.ai have marketing attribution?

No. Otterly.ai is focused exclusively on AI search visibility monitoring. It does not provide first-party tracking, multi-touch attribution, conversion deduplication, budget optimization, or any traditional marketing analytics capabilities. If you need attribution, you would need a separate tool alongside Otterly.

Can I use TrustData just for AI visibility?

Yes. Every TrustData plan includes AI visibility monitoring. The Track plan (EUR 49/month) gives you 1,000 probes/month across 2 engines (ChatGPT, Gemini) with Brand Visibility Index and share of voice. You can use it purely for GEO monitoring without touching the attribution or optimization features.

What is generative engine optimization (GEO)?

Generative engine optimization (GEO) is the practice of optimizing your content so that AI search engines (ChatGPT, Gemini, Perplexity, Claude) mention and recommend your brand in their AI-generated answers. GEO is to AI search what SEO is to Google's traditional results. Both TrustData and Otterly provide GEO monitoring tools, but TrustData adds content experiment capabilities with before/after proof.

TrustData vs Otterly.ai: Two Different Approaches to AI Visibility

Otterly.ai is a purpose-built AI visibility monitoring tool. It tracks how your brand appears in AI-generated answers from ChatGPT, Perplexity, Google AI Overviews, and Copilot. It does one thing and does it well.

TrustData is a full marketing analytics platform that includes AI visibility monitoring in every plan, alongside first-party tracking, multi-touch attribution, budget optimization, and incrementality testing. AI visibility is not an add-on; it's built into the core product.

The choice depends on what you need: if AI visibility monitoring is your only requirement, Otterly is a focused tool for that. If you need AI visibility and marketing measurement in a single platform, TrustData eliminates the need to stitch together multiple tools.

Where Otterly Wins

Lower entry price: EUR 29/month for basic AI monitoring vs TrustData's EUR 49/month.
Google AI Overviews tracking: Otterly monitors Google's AI Overview results directly. TrustData focuses on standalone AI engine responses.
Simplicity: If you only need AI visibility monitoring and nothing else, Otterly is a lighter tool with no extra features to ignore.
Semrush integration: Available as a Semrush App Center plugin if you already use Semrush.

Where TrustData Wins

More engines, more probes: 7 engines and up to 50,000 probes/month vs 4 engines and up to 1,000 prompts.
No per-engine add-ons: All engines included in the tier price. No surprise costs for adding Gemini or new engines.
Full marketing stack: AI visibility + attribution + budget optimization + incrementality in one platform. No need to combine Otterly with a separate attribution tool.
Content experiments with proof: Natural control groups and adjusted before/after verdicts tell you whether a content change actually improved AI visibility, not just whether mention rates went up.
GEO page audits: Automated content scoring that tells you which pages need optimization for AI extractability.
Cost efficiency at scale: At the Optimize tier (EUR 497/month), you get 10,000 probes across 7 engines plus full marketing analytics. Otterly's Premium (EUR 989/month) gives you 1,000 prompts and AI monitoring only.

Which One Should You Choose?

Choose Otterly if: AI visibility monitoring is your only need, you already have attribution covered by another tool, and you want the lowest possible entry price for basic brand monitoring.

Choose TrustData if: You need AI visibility monitoring and marketing measurement in a single platform. If you're currently paying for both an analytics/attribution tool and a GEO monitoring tool separately, TrustData consolidates both, often at a lower total cost.

The fundamental difference: Otterly is a monitoring tool. TrustData is a measurement platform that includes monitoring. The question is whether you need the full stack or just the monitoring layer.
