Thesia, inside your agent. The Aetherya MCP turns audience simulation into tools any agent can call.
Test a site, a headline or an idea against a synthetic audience without leaving the editor.
Capabilities
What your agentcan do with it.
Evidence from a synthetic audience, inside the loop, before a human reviews the work or a dollar is spent.
- 01Audit what it just builtYour agent audits a page, or walks a sign-up or checkout flow, and gets predicted friction, hesitation and drop-off back with concrete fixes.
- 02Decide before it buildsHand it a decision in plain English. Aetherya designs the study, builds the audience and quotes the price. Nothing runs until you approve it.
- 03Compare copy and creativeRank headline and ad variants, or pretest images and video, on predicted response, comprehension and trust, with the objections each one raises.
- 04Get a read in secondsCheck a handful of variants against a market population and see which archetypes favour each, before spending anything on the full study.
- 05Rehearse a postRun a post or an email through a synthetic audience first: predicted engagement, sentiment and representative reactions.
- 06Hand back a decisionAny finished run becomes a short brief with the answer, the reasoning, the risks and the next step, plus a link you can share.
