# Potato — Multi-Field Spans

Span annotation across multiple text fields.

A live demo of **[Potato](https://www.potatoannotator.com)** — the free, self-hosted annotation platform for NLP,
agentic, and GenAI research, configured entirely through YAML.
Visit **[www.potatoannotator.com](https://www.potatoannotator.com)** for docs, the schema gallery, and more demos.

## Try it out

1. Enter any username to log in (no password required).
2. Read the item shown in the main panel.
3. Annotate using the schemes on the right.
4. Click **Next** to continue.

> **Run your own copy:** this demo is generated from a project in the Potato repo. Clone it and
> start that project directly — no HuggingFace account needed, and no concurrency limit:
> `python potato/flask_server.py start <example>/config.yaml -p 8000`.
> Duplicating a Space instead requires a HuggingFace PRO, Team or Enterprise plan, because
> Docker Spaces run on compute.

> Annotations in this demo are ephemeral. To collect and keep data, deploy your own
> Space — see the [deployment guide](https://github.com/davidjurgens/potato/blob/master/deployment/huggingface-spaces/deploy.md).
