## What it is
OpenBoard is an open-source cross-platform interactive whiteboard application designed primarily for classroom use in schools and universities. It supports writing and annotation with a graphics tablet, interactive whiteboard, or mouse, and is built with Qt for Windows, macOS, and Linux.

## Use cases
- interactive whiteboard software for classrooms
- annotate lessons on a tablet or smartboard
- free whiteboard app for teachers
- draw and write on screen during lectures
- dual-screen teaching with tablet and projector
- open-source alternative to commercial whiteboard software

## When to choose
- you are a teacher or lecturer needing a free whiteboard for class
- you use an interactive whiteboard, graphics tablet, or dual-screen setup
- you need a cross-platform tool on Windows, macOS, or Linux
- you want an actively maintained, community-driven open-source project

## When to avoid
- you need collaborative cloud-based whiteboarding with remote teams
- you want a lightweight quick-sketch tool rather than full classroom software
- you require platforms outside Windows, macOS, or Debian-supported Linux
