# Glossary

> The words this documentation uses, defined plainly.

## Account

You: one sign-in, one profile. An account can belong to several workspaces.

## Audit trail

A record of every merged change, who approved it and when.

## Builder

The part of Automo Build that reads your message, plans the change, writes the code and checks the result.

## Conductor

The orchestration layer for running many projects at once: fleet view, Protected Code Zones, moderation and live health. See [Conductor](/collaborate/conductor).

## Credit

The unit building work is measured in. See [How credits work](/plans/how-credits-work).

## Custom domain

A domain you own, pointed at a project, so the app lives at your address.

## Custom sandbox

A sandbox image that wraps AI-assisted engineering around an existing stack such as Rails, Java, Go, Python or Node.

## Database

The part of the app that remembers things after the browser closes. Records live in tables with access rules.

## Doctor

A read-only AI SRE that diagnoses problems on the live app and drafts a fix for approval. See [Doctor](/publish/doctor).

## Environment

Either **preview** (where you are working) or **live** (what other people see). Publishing moves the preview to live.

## Guardrails

Governance for AI changes: business areas, risky-change detection, plain-English policies, human review and an audit trail. See [Guardrails](/build/guardrails).

## Integration

A service connected to a project, such as a payment provider, an email sender, a calendar or an AI model.

## Live

The published version of the app, served on its address or your custom domain.

## Migration

A structured change to a database that already contains data, such as adding a column. Migrations need care and a backup.

## Preview

The always-current version of the project while you build. Customers do not see it.

## Project

One app: its code, database, history and publishing settings.

## Protected Code Zone

An area of code, such as billing or auth, locked so the AI cannot change it without the required approval.

## Publish

The action that makes the current preview the live app.

## QA

Automated testing that replays key journeys in a browser and gates publishing. See [Automated QA](/build/automated-qa).

## Role

What a person is allowed to do in a workspace. Separate from the roles inside your app.

## Secret

A private value, such as an API key, used only by server code and never placed in browser code.

## Security scanning

Static scans, dependency checks and live probes that confirm real vulnerabilities. See [Security scanning](/build/security-scanning).

## Server function

Code that runs on the server rather than in the browser. Used for anything that needs a secret or a trusted check.

## Version

A saved state of a project after a change.

## Webhook

An automatic message from one system to another when something happens.

## Workspace

The shared home for a team: members, projects, billing and integrations.
