# Thesia Platform Overview

Thesia, by Aetherya, tests a page, a message, a price, an ad or a post on a simulated audience before it goes out. It reports what people would likely do, where they would hesitate, and why, with the evidence behind each result. Every result is a simulated prediction, not real-user data.

## What it does

- **Reads**: 2–5 variants of copy, an offer, a page, a creative or a video read against a market population in seconds. Counted against a monthly read allowance.
- **Studies**: message tests, concept tests, pricing sensitivity (Van Westendorp), focus groups, one-on-one interviews, feature adoption and open decisions. Each returns a verdict, segment differences, objections and quotes.
- **Site audits**: simulated visitors open a URL in a real browser, or walk a flow such as sign-up or checkout, and report friction, hesitation and drop-off with fixes.
- **Creative pretests**: image and video ads compared on a simulated audience.
- **Post simulations**: a social post or an email tried before it goes out.
- **Audiences**: describe a segment in plain language ("first-time SaaS buyers in Germany") and Thesia generates the people, or ask them open questions directly.
- **Decision briefs**: any finished run becomes a short brief with the question, the answer, the reasons, the risks and what to do next, and a link you can share.
- **Metis**: the assistant on paid plans. It runs all of the above from a conversation and remembers your work.

## Key concepts

| Term | Meaning |
|---|---|
| Session | The unit that full simulations are priced in through the API and MCP. The app shows the same usage as a share of your plan |
| Read | A fast population estimate. It uses the read allowance, not sessions |
| Persona | One simulated person in an audience |
| Audience group | A named list of personas that a study can target |
| Audit | A simulated browser run over a URL or flow, returning findings and fixes |
| Study | A structured run of one research method against an audience |
| Autopilot | One plain-language question that Thesia turns into a designed, priced study. Nothing is spent until the price is accepted |
| Brief | The short decision document built from a finished run |

## API and MCP access

Thesia is available as a REST API and an MCP (Model Context Protocol) server. Both need an `aeth_live_` API key created in the dashboard.

- REST API base: `https://api.aetherya.ai/api`
- MCP: [/mcp.md](/mcp.md), as the `@aetherya/mcp` npm package or the hosted server at `https://mcp.aetherya.ai/mcp`
- API quickstart: [/agent.md](/agent.md)
- OpenAPI schema: [/openapi.json](/openapi.json)

## How to read the results

Results are simulated. Every signal comes from a simulated audience and predicted behavior, not from real people. Use them to decide what to change and what to test with real customers.
