# Demo / Try Model

The **Try Model** view (`/demo`) is a lightweight sandbox for testing model
behavior without creating a full annotation project.

## What it is for

- quick model sanity checks
- ad-hoc text exploration
- testing concept filters before project setup

It does **not** persist annotation decisions like a project workflow does.

## Workflow

1. Select a **Model Pack**.
2. Optionally add CUI filters:
   - pick concepts from the concept picker, or
   - paste a comma-separated CUI list.
3. Optionally enable **Include sub-concepts**.
4. Enter or paste free text.

The text is annotated automatically after a short pause or when focus leaves the
editor.

## Output panels

- **Main text panel**: highlighted entities in context.
- **Concept Summary**: details for the selected entity.
- **Meta Annotations Summary**: model-predicted meta annotation values (if
  available in the model pack).

Double-clicking the rendered text switches back to edit mode.
