# Kranth FAQ

## What is Kranth?
Synthetic audience infrastructure: adversarial AI personas stress-test ideas before real strangers do.

## Does it predict the market?
No. It surfaces objections and themes. It is not a forecast.

## How many personas?
50 to 1,000 per simulation. Free plans cap at 100. Paid plans cap at 1,000.

## What is A then B?
One room, two versions. Same people hit A, we rewrite B from what they hated, they hit B. You get a call: ship B, keep A, or split. That is the simulation, not a second bill.

## How is the score calculated?
Weighted average of persona sentiments; dashboard maps −1…+1 to 0–100 with 50 = neutral. Hostile reactions count more. Compare runs show both scores.

## API?
Yes. REST + SSE. Keys `kr_live_…`. Spec: https://kranth.ai/docs.txt and OpenAPI.

## Training on my data?
Off by default. Enterprise can lock no-training contractually.

## vs human panels?
Panels win for lived experience. Rooms win for speed, cost, and adversarial coverage before you spend on panels.

## vs surveys?
Surveys count preferences. Rooms stage pushback and multi-angle dissent.
