Choose a model

AlchemyAPI is trained on billions of webpages and can detect and extract information such as concepts, entities, sentiment, and keywords. Alternatively, you can train a custom model to identify specific entities and typed relations that are unique to your domain or industry, for example law or finance.

Choose which model to try:

The default public model is trained with English websites and news content.
The example custom model is trained on traffic incident reports, and will find specific entities in text such as part of car, accident outcome, or impact instead of merely understanding general entities like automobile.
