Draw any ontology you want, the way you want. Intuitive drag-and-drop interface with customizable nodes and relationships.

Save, view, and edit your ontologies in our built-in manager. Access your projects later with just one click.

Export your ontology to multiple formats:

• OWL (Web Ontology Language)
• XML (Structured data)
• SVG (Scalable vector graphics for diagrams)

Build better ontologies with real-time feedback. The console suggests modeling best practices and detects inconsistencies.

Write correct class axioms effortlessly with guided syntax support and auto-completion.

Designed for everyone—from beginners learning ontologies to advanced researchers. Clean UI with contextual help.

Includes a simple yet powerful thesaurus editor for lightweight vocabulary management.

Quick-access knowledge base for reference ontologies:

1. Clone the repository to your computer;

2. Inside the project's main folder, create a file named: .env;

(You can skip steps 2 and 3 by navigating to the folder in a terminal and using the command "copy .env.example .env")

3. Copy the contents of the .env.example file to the newly created .env file;

4. Access the repository via a terminal and run the command: composer install

5. Still in the terminal, generate an application key with the command: php artisan key:generate

6. Configure the .env file with your local database settings;

Example:

DB_DATABASE=your_database_name
DB_USERNAME=your_username
DB_PASSWORD=your_password

7. In the terminal, run the migrations with the command: php artisan migrate --seed;

Note: The "--seed" flag is only for seeding the database. If you don't want the database pre-populated, remove this flag from the command.

8. To run the project, use the command: php artisan serve;

9. Access the URL provided in the terminal.
