[![Codacy Badge](https://app.codacy.com/project/badge/Grade/35ac8625a2bc4eddbff23dbc61bc6abb)](https://www.codacy.com/gh/doccano/doccano/dashboard?utm_source=github.com&utm_medium=referral&utm_content=doccano/doccano&utm_campaign=Badge_Grade)

doccano is an open-source text annotation tool for humans. It provides annotation features for text classification, sequence labeling, and sequence to sequence tasks. You can create labeled data for sentiment analysis, named entity recognition, text summarization, and so on. Just create a project, upload data, and start annotating. You can build a dataset in hours.

## Demo

Try the [annotation demo](http://doccano.herokuapp.com).

## Features

- Collaborative annotation

- Dark theme

## Usage

There are three options to run doccano:

- pip (Python 3.8+)
- Docker
- Docker Compose

### pip

To install doccano, run:

```bash
pip install doccano
```

By default, SQLite 3 is used for the default database. If you want to use PostgreSQL, install the additional dependencies:

```bash
pip install 'doccano[postgresql]'
```

and set the `DATABASE_URL` environment variable according to your PostgreSQL credentials:

```bash
DATABASE_URL="postgres://${POSTGRES_USER}:${POSTGRES_PASSWORD}@${POSTGRES_HOST}:${POSTGRES_PORT}/${POSTGRES_DB}?sslmode=disable"
```

After installation, run the following commands:

```bash
# Initialize database.
doccano init
# Create a super user.
doccano createuser --username admin --password pass
# Start a web server.
doccano webserver --port 8000
```

In another terminal, run the command:

```bash
# Start the task queue to handle file upload/download.
doccano task
```

Go to .

### Docker

As a one-time setup, create a Docker container as follows:

```bash
docker pull doccano/doccano
docker container create --name doccano \
-e "ADMIN_USERNAME=admin" \
-e "[email protected]" \
-e "ADMIN_PASSWORD=password" \
-v doccano-db:/data \
-p 8000:8000 doccano/doccano
```

Next, start doccano by running the container:

```bash
docker container start doccano
```

Go to .

To stop the container, run `docker container stop doccano -t 5`. All data created in the container will persist across restarts.

If you want to use the latest features, specify the `nightly` tag:

```bash
docker pull doccano/doccano:nightly
```

### Docker Compose

You need to install Git and clone the repository:

```bash
git clone https://github.com/doccano/doccano.git
cd doccano
```

_Note for Windows developers:_ Be sure to configure git to correctly handle line endings or you may encounter `status code 127` errors while running the services in future steps. Running with the git config options below will ensure your git directory correctly handles line endings.

```bash
git clone https://github.com/doccano/doccano.git --config core.autocrlf=input
```

Then, create an `.env` file with variables in the following format (see [./docker/.env.example](https://github.com/doccano/doccano/blob/master/docker/.env.example)):

```plain
# platform settings
ADMIN_USERNAME=admin
ADMIN_PASSWORD=password
[email protected]

# rabbit mq settings
RABBITMQ_DEFAULT_USER=doccano
RABBITMQ_DEFAULT_PASS=doccano

# database settings
POSTGRES_USER=doccano
POSTGRES_PASSWORD=doccano
POSTGRES_DB=doccano
```

After running the following command, access .

```bash
docker-compose -f docker/docker-compose.prod.yml --env-file .env up
```
