Evertune

Evertune is a Generative Engine Optimization (GEO) and AI brand-intelligence platform that helps brands, marketers, and agencies understand, measure, and influence how they appear in AI-driven recommendations. As discovery shifts from traditional search engines to conversational answer engines like ChatGPT, Claude, Gemini, and Perplexity, Evertune tracks brand visibility and sentiment across 10+ AI models, analyzes how large language models describe a brand versus its competitors, and delivers prescriptive message and content briefs to improve that positioning. The platform combines large-scale prompt testing (100,000+ prompt responses per report via direct base-model API access), the EverPanel consumer panel, daily consumer-app data, an AI Brand Index and AI Brand Score, content activation, and AI advertising. Founded in 2024 by operators who helped scale The Trade Desk, Evertune is backed by Felicis and serves customers including Roku, WPP, athenahealth, and HexClad. Evertune is a data consumer of the major model APIs; it does not currently publish a first-party developer API, SDK, or OpenAPI.

Evertune is profiled on the APIs.io network. Tagged areas include Company, Generative Engine Optimization, AI Search, Brand Monitoring, and Marketing Intelligence.

Evertune’s developer surface includes documentation, pricing, engineering blog, signup flow, YouTube channel, authentication, and 13 more developer resources.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/evertune: open an issue to ask a question, or submit a pull request to add artifacts.

  detail: 'Evertune is a consumer of the model providers'' APIs rather than a publisher of one — its own FAQ says base-model
    data is "reachable only through direct API integration with the model provider" — and it ships no developer surface of
    its own: the pricing page''s two demo-led tiers name no API access, the Intercom help center holds three end-user articles,
    and app.evertune.ai is a closed SPA whose backend is undocumented; the only machine-readable thing Evertune serves is
    the Auth0 OIDC discovery document on auth.evertune.ai, which signs users in to that app.'
