+# Joplin Tool for Open WebUI
+
+## Description
+
+Permet a Effi de lire et ecrire des notes dans Joplin via l'API Clipper (locale). Gestion de notes, notebooks et TODOs directement depuis le chat.
+
+**Important** : L'API Clipper fonctionne uniquement quand l'app Joplin desktop est ouverte et le Web Clipper active (Options → Web Clipper).
+
+## Installation
+
+1. **Admin Panel** → **Tools** → **Create Tool** (ou +)
+2. **Name** : `Joplin`
+3. **Description** : `Notes Joplin. Commandes: list_notebooks(), list_notes(notebook_id), get_note(id), create_note(title, body, notebook_id), update_note(id, title, body), search_notes(query), create_notebook(name), add_todo(note_id, text), toggle_todo(note_id, completed)`
+4. **Coller le code ci-dessous**
+5. **Save and Activate**
+6. **Configurer les Valves** via la roue crantee :
+   - `joplin_url` : `http://192.168.1.11:41184` (IP du PC ou Joplin est ouvert)
+   - `joplin_api_token` : votre jeton API (Options > Web Clipper > Jeton d'authentification)
