AthenaHQ lists a free Essential plan, a self-serve Starter plan and a custom Enterprise plan, all metered in credits, where one credit is one AI response. Essential covers ChatGPT, Perplexity, Gemini, Google AI Overviews and Copilot; Starter tracks 11 models, adding Google AI Mode and Claude among others. PromptSignal tracks seven engines, publishes its measurement method, and adds white-label, private cloud or on-premise deployment and custom work built by our engineers.
Where AthenaHQ is strong
AthenaHQ is easy to try: Essential is free, with starter credits and unlimited users. On paid plans, prompts and competitors are unlimited, and you choose which models run on which days of the week, so credit spend follows the schedule you set. More models are available on request.
It pairs measurement with tools to act. Ask Athena, an in-app copilot, answers plain-language questions from your visibility, citation and competitor data. Paid plans add on-page and off-page actions and a content optimization agent, and Enterprise adds the Athena Citation Engine. A Shopify integration publishes optimized product content and attributes revenue to AI search, and GA4, Search Console and Webflow connect as well. The Responses page keeps each full answer with its sources and your brand's rank, and paid plans export it to CSV. Developers get an API on paid plans, as an add-on on Starter, and MCP setup for Claude.ai.
Agencies get discounted partner licenses, multi-brand management and pitch workspaces. AthenaHQ's enterprise page lists SOC 2, GDPR and the NIST Cybersecurity Framework at Tier 3.
Where PromptSignal differs
A published method. PromptSignal publishes its methodology: six engines are captured from the same interfaces your buyers use, Claude is measured through its API with web search, and visibility is the share of runs that name you. Prompts can run in 72 countries and 32 languages, every 48 hours by default. AthenaHQ's public pages do not say how it collects answers, and its metric glossary sits inside the app.
White-label. PromptSignal offers white-label with your logo, your colors and your own domain, set up with our team. AthenaHQ's agency page does not mention white-label, though its dashboards can be embedded by iframe.
Deployment and custom work. PromptSignal offers private cloud or on-premise deployment, delivered with our engineers, and our engineers build custom engines, markets, prompt sets and integrations. AthenaHQ does not publish a private cloud or on-premise option.
How to choose
AthenaHQ suits teams that want to start free, need a long model list on a self-serve plan, or sell on Shopify. PromptSignal suits teams that need to show stakeholders how each number is measured, agencies that need the app under their own brand, and companies that need it in their own cloud or data center.
