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?'

Which tool monitors more AI engines?

TrustData probes ChatGPT and Perplexity on every tier and reads Google AI Overviews per tracked keyword. Gemini, Claude, Mistral, DeepSeek and Google AI Mode are per-tier add-ons rather than bundled. Otterly covers ChatGPT, Perplexity, Google AI Overviews, and Copilot on its standard plan, with Gemini available as a paid add-on. Every TrustData tier ships ChatGPT and Perplexity probes plus Google AI Overview tracking, and Gemini, Claude, Mistral and DeepSeek are per-tier add-ons from EUR 15 a month, so you pay for the engines your buyers actually use.

Is TrustData cheaper than Otterly for AI visibility?

It depends on what you need, and the honest answer is often Otterly. Its Lite plan starts at USD 29/month with 15 prompts, and Standard at USD 189 adds API and MCP access. Competitor pricing checked August 2026. If AI visibility monitoring is the only thing you want, that is the right purchase and TrustData is the wrong one. TrustData starts at EUR 199/month (Measure) with 50 monitored prompts, 3,000 probes, first-party tracking, multi-touch attribution, tracking integrity and alerting. It is built for brands spending EUR 50K/month or more on ads, where one subscription replaces a GEO tool plus an attribution tool plus a tracking monitor. Below that spend, a standalone GEO tool is the better fit.

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. Measure (EUR 199/month) gives you 50 monitored prompts and 3,000 probes/month on ChatGPT and Perplexity plus Google AI Overview tracking, with Brand Health Score and share of voice. The five other surfaces are per-engine add-ons from EUR 15/month. You can use it purely for GEO monitoring, though if that is all you need, a standalone GEO tool will cost less.

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: AI Visibility Monitoring Compared

Otterly.ai is a standalone AI visibility monitoring tool. TrustData includes AI visibility in every plan alongside attribution, budget optimization, and incrementality testing. Here's how they compare.

By Martin Préjean·Founder

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 199/month. If AI visibility is the only thing you need, Otterly is the cheaper and more appropriate purchase.
Microsoft Copilot coverage: Otterly probes Copilot. TrustData does not, so a brand whose buyers work inside Microsoft 365 will have a gap.
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

Probe volume: up to 24,000 probes a month on Prove against Otterly's prompt-based tiers. On raw baseline engines Otterly is ahead, at four included against our three, so the comparison to make is depth per prompt rather than logos on a page.
Both Google surfaces: AI Overview tracking ships with every tier, and Google AI Mode is available as an add-on priced per tracked keyword. Otterly reads AI Overviews only.
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 Optimize (EUR 497/month) you get 150 monitored prompts, 9,000 probes, and full marketing analytics: attribution, tracking integrity, paid optimization. Otterly's Premium (EUR 989/month) gives you 1,000 prompts and AI monitoring only. The comparison is one subscription against three.

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.
