# On Book Product Family

> **Product scope:** On Book Pro documents production-management workflows. On Book Rehearsal documents proposed personal rehearsal workflows.

***

## Products

| Product | Documentation Scope | Purpose |
|:---|:---|:---|
| On Book Pro | Product documentation | Production management for stage managers, production teams, and collaborators |
| On Book Rehearsal | Proposed / pre-launch | Personal rehearsal and memorization companion |

## Shared Concepts

Both products are intended to share:

* On Book account identity
* Script understanding workflows
* Theatre vocabulary
* AI-assisted script processing

## Separate Promises

Do not assume every Pro feature exists in Rehearsal or every Rehearsal page describes shipped behavior.

Use page notes only when the reader needs a real availability or usage boundary:

* **Stable**: shipped and documented accurately.
* **Requires access**: available only when a project or account has the named access flag.
* **Proposed / pre-launch**: intended behavior, not a current production promise.
