# Introduction to Plural: Robot & Avatar Platform

> Plural is a no-code SaaS platform by Humanizing Technologies for programming humanoid robots and 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 humanoid robots and virtual Avatars — all without writing a single line of code. Whether you want a robot 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.

## Supported devices

Plural works across four device types. Most documentation applies to all of them; where behaviour differs, pages are clearly marked with the device name (e.g. **Flow (NAO)** or **Change company logo (Avatar)**).

## 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 robots or 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.
