How to Use the Extension

Using the Writer browser extension is simple and intuitive. Enhance your text directly from any webpage in three easy steps.

Self-Hosting the API Backend

Deploy your own Writer API server for complete data privacy. Your text never leaves your infrastructure — full control, full privacy.

Quick Start

1. Prerequisites

Ensure you have Docker and Docker Compose installed on your system.

docker --version
docker-compose --version

2. Create Environment File

Copy the example environment file and configure your settings:

cd api
cp .env.example .env
nano .env # Edit with your settings

3. Start the Container

Launch the API server with Docker Compose:

docker-compose up -d
docker-compose ps # Verify it's running

4. Configure the Extension

Point Writer to your self-hosted API:

API Endpoint: http://localhost:3001
API Token: (from your .env)
