# Introduction to Plural: Avatar Platform

> Plural is a no-code SaaS platform by Humanizing Technologies for building interactive virtual Avatars using a visual flow builder.

Plural is a no-code SaaS platform built by Humanizing Technologies that lets you design, deploy, and manage interactive experiences for virtual Avatars — all without writing a single line of code. Whether you want an Avatar to greet visitors at a trade show, guide patients through a hospital, or power a virtual customer-service agent on a smart TV, Plural gives you the tools to build it in minutes.

## The Avatar

Plural runs as a browser-based virtual Avatar on any device with a modern web browser — smartphone, computer, smart TV, or kiosk. There is no app to install: open a link and the Avatar is ready to interact.

## Key concepts

Understanding four core concepts will help you get the most out of Plural:

**Projects** — A Project is the container for your entire interactive experience. One project can target multiple Avatars at once, each represented by its own frame inside the flow builder.

**Flow Builder** — The visual canvas where you design your experience. You connect Elements together with arrows to define the conversation or interaction flow.

**Elements** — The building blocks you drag onto the canvas. Elements include things like *Robot Says* (speech), *User Input*, *Image Display*, buttons, timers, and more. A rich library of Elements lets you build sophisticated interactions without code.

**GOs** — The in-platform credit unit used for AI-powered features like Text-to-Speech (TTS) and Speech-to-Text (STT). Testing in Preview Mode without speech recognition enabled does not consume GOs.
