Evertune

The Solution & Approach

Evertune's flagship AI Brand Index measures how often and how prominently a brand surfaces in AI answers to category questions like "what's the best espresso machine under $200," when the brand is not named in the prompt. It tracks nine AI surfaces (ChatGPT, Gemini, Claude, Perplexity, Meta, DeepSeek, Copilot, Google AI Overviews, and AI Mode) and runs more than 100,000 prompts per brand report. The Index resolves to three scores: a Visibility Score for frequency of appearance, an Average Position for where the brand lands in the answer, and a combined AI Brand Score.

The angle is statistical scale plus adtech pedigree. Felicis contrasted Evertune's 100,000+ prompts per report against competitors that "prompt the model just a handful of times." The founding team came out of The Trade Desk, and through 2026 Evertune extended from measurement into media activation: programmatic AI retargeting with Index Exchange and The Trade Desk, affiliate activation with impact.com, B2B partner activation with PartnerStack, and a paid-placement ad agent, Visibility Boost, that buys ChatGPT ad placements against the queries where a brand's organic AI visibility is weakest.

That media-buying step is the category POV. Evertune is the first tracked AEO/GEO vendor to ship a paid-placement agent on top of its measurement layer, moving from measuring AI visibility to buying it. Its Topic Relevance and Brand Relevance metrics push a related argument that citation frequency is not influence. In one internal test the most-cited source ranked 33rd in actual influence, and the 48th most-cited source was the most influential.

Best for

Enterprise marketing teams that want out-of-prompt AI brand measurement at statistical scale and a path from measurement into media activation.

Pricing & trial

Sales-led with no public pricing; a third-party comparison puts it around $36K per year, and there is no listed free trial. Pricing.

Agent Experience

How you build on this platform (or wire it into your own agents):

Thin platform to build on: the docs are a roughly six-article help center with no public API reference, and Evertune's direct model access powers its own reports rather than a developer surface you build on top of.
