Test your ad before
you spend a dollar on it.
Hyper Sling scores your creative against a compendium of AI personas across five foundation models — then ranks your variants against the one baseline that matters: whether a persona predicts real outcomes better than the raw model. A focus group in minutes, not weeks.
Early access for software builders and marketers. We email rarely and never share your address.
Upload your headlines, copy, and CTAs. Hyper Sling permutes them into a variant matrix — your components, never AI-invented ones.
Every variant is judged by a weighted set of personas across five models, each measured against a no-persona baseline.
Ship the winner to your ad platform — or dry-run the whole flow first, spending nothing.
Built on one discipline: a persona only earns its vote if it predicts reality better than the vanilla model. No eloquence, no vibes — measured signal.
