# Key concepts

> How Versive is organized: studies, AI tests, personas, credits, and workspaces

A quick tour of the building blocks you'll see everywhere in Versive.

## Studies

A **study** is research with real participants: an AI-moderated survey or interview that participants complete through a link, an embed on your site, or a recruited panel. Studies collect **interviews** (individual participant sessions) as responses, and can be paused or archived at any time. See [Studies overview](/studies/overview).

## AI tests

An **AI test** simulates users instead of recruiting them: AI personas evaluate a Figma prototype, a live website, or uploaded design images and produce transcripts, findings, and prioritized recommendations in minutes. See [AI tests overview](/ai-tests/overview).

## Personas

**Personas** are reusable AI participant profiles. You can write them by hand or generate them from your own research files (interview transcripts, survey exports, research docs). Personas power [AI tests](/ai-tests/overview) and can also take your studies as [simulated participants](/studies/launch-and-sharing#simulate-ai-test-participants) — a great way to test a study before launch. See [AI personas](/ai-tests/personas).

## Credits

Usage on Versive is measured in **credits**, shared across both product lines:

| Action                                                              | Credits                              |
| ------------------------------------------------------------------- | ------------------------------------ |
| Completed interview (Regular AI engine)                             | 1                                    |
| Completed interview (Realtime AI engine)                            | 2                                    |
| AI test run — Figma prototype or image test (per persona execution) | 1                                    |
| AI test run — website test                                          | 1 (up to 2 with extended step limit) |

Study creation and AI analysis are unlimited on all plans — credits are only consumed when responses or test runs actually complete. We also offer cheaper credits for non-AI surveys (the Survey engine) — contact [support@getversive.com](mailto:support@getversive.com) if you'd like to set that up.

## Templates

The **Library** holds reusable building blocks: question templates, study templates, and email outreach templates, organized into color-coded categories. See [Templates & the Library](/platform/templates).

## Organizations

Everything in Versive lives inside an **organization** — your team's workspace. An organization has its own members, folders, studies, AI tests, persona library, templates, billing, and API keys. If you belong to several organizations (common for agencies running research for multiple clients), you can switch between them from the workspace menu.

## Folders

**Folders** organize your studies and AI test projects. Folders can be nested, and each folder has an access policy that controls what other members of your organization can do inside it — from full access down to invite-only. See [Folders & permissions](/platform/folders-and-permissions).

## Roles

Access is controlled at two levels: **organization roles** (Owner, Admin, Creator, and Member) and **study/folder roles** (Owner, Full access, Editor, Commenter, and Viewer). See [Organizations & roles](/platform/organizations-and-roles).
