Useful prompt-led query and volume intelligence, but the official product pages do not establish a conventional keyword database or keyword difficulty suite.
The Grüns case study says Athena's Prompt Planner identified high-monthly-search prompts using volume and mention intelligence across ChatGPT, Perplexity, and AI Overviews. https://athenahq.ai/case-studies/10-6pp-sov-gruns-ai-search-case-study

Semrush

Pro+ includes multi-location/device tracking: https://www.semrush.com/pricing/seo-ai-search/
Technical SEO
Diagnostics
How strong the tool is for crawling, audits, indexability, metadata, status codes, and technical site health.
AthenaHQ
Some technical AI-crawler and structured-content support is present, but the site does not document a broad technical SEO audit/crawl module.

Semrush
Official pages support content optimization and describe content workflows, but do not establish a full native publishing workflow for the core product.

AthenaHQ
The product has a free Essential tier and a free audit CTA, but the official pages do not show a separate catalog of standalone free SEO tools.

Market proof
Estimated customer or user scale based on public claims, with source claims stored separately for auditability.
AthenaHQ

Semrush
Official company materials provide meaningful adoption figures, though the clearest paying-customer figure is from 2023.

Agent readiness level
Automation
How ready the product is to operate as or inside an AI agent workflow, based on tracked subcriteria for autonomy, controls, integrations, memory, and evaluation.

Agent-native features are central: Ask Athena, Athena AI agent, recommendation/content agents, and an Athena Citation Engine.

Semrush
MCP access and API data integration provide machine-access paths, but the evidence does not establish a broadly autonomous SEO agent.
Starter includes MCP access and Advanced includes API data integration: https://www.semrush.com/pricing/seo-ai-search/
Ease of use and autonomous level
Automation
How easy it is for a team to reach useful outcomes, and how much work the product can perform autonomously after setup.
AthenaHQ
High assisted autonomy for diagnosis and recommended execution, with evidence of self-learning and largely self-running Enterprise workflows; human review remains relevant.
Starter advertises self-learning content improvement, while the Grüns customer says the Enterprise platform largely runs itself and describes human-in-the-loop proofreading. https://athenahq.ai/pricing https://athenahq.ai/case-studies/10-6pp-sov-gruns-ai-search-case-study
Semrush
AI-powered recommendations and AI visibility features assist workflows, but human execution remains necessary.
