Accessible Tools

Open-source tools built for blind and low-vision users — designed to be fully usable with screen readers and keyboard navigation.

Quick start

All projects in this repository share a single virtual environment at the repository root:

# Windows (PowerShell)
python -m venv .venv
.\.venv\Scripts\Activate.ps1

# macOS / Linux
python3 -m venv .venv
source .venv/bin/activate

Always activate .venv before running any project or its tests.
