The tools at a glance
Athena HQ
Free-to-start GEO audit platform with citation gap analysis and API access on paid plans
Athena HQ is a generative engine optimization platform built around a free GEO audit, paired with paid plans that unlock deeper analysis. It tracks brand appearances across ChatGPT, Claude, Gemini, and Perplexity on all tiers, including the free Essential plan. The standout feature is the Essential tier itself: a genuine free plan that runs a real audit of your AI citation performance, surfaces which competitors are winning in your category, and identifies content gaps that may be holding your brand back.
The paid plans focus on depth rather than coverage. Citation source tracking, unlimited competitor benchmarking, and API access unlock at the $295/month Starter tier, with no mid-priced option in between. The content gap analysis is the centerpiece of the platform: Athena HQ compares your site content coverage to the topics AI models are pulling from competitor sites, and flags specific topic areas to prioritize in your content calendar.
The main friction versus Otterly.AI is engine coverage and entry price point. Athena HQ covers 4 engines and has a free tier plus a $295/month jump to API access; Otterly.AI covers 7 engines starting at $29/month but locks API access to Standard. For teams whose priority is free entry plus Claude coverage, Athena HQ is the practical choice. For teams whose priority is broader engine coverage at $29/month, Otterly.AI is the more appropriate fit.

Otterly.AI
Track brand visibility across 7 AI engines from $29/month with API and MCP support
Otterly.AI is an AI search monitoring platform that tracks how and where a brand appears across ChatGPT, Google AI Overviews, Google AI Mode, Perplexity, Microsoft Copilot, Claude, and Gemini. It positions itself as a generative engine optimization (GEO) tool, meaning it goes beyond showing where a brand appears and actively recommends changes to improve citations.
The platform launched with one of the most competitive price points in the category. At $29/month for the Lite plan, teams get real tracking across all 7 AI models, answer ranking monitoring, and citation link analysis. That is significantly cheaper than most dedicated AI visibility tools, which tend to start at $79 to $99/month for comparable coverage.
The trade-off versus Athena HQ is API access timing and the absence of a free tier. Otterly.AI's Lite plan gives a solid monitoring dashboard but no API access and no MCP integration. Teams that want to pull data into their own tools or connect Otterly to an agent stack will need to upgrade to the Standard plan at $189/month. For solo marketers or small in-house teams who just need visibility data without the technical plumbing, the Lite plan is hard to beat on price.
