For the `textcat.teach` command, can I do on a custom model (like the model I trained through `ner.train`) ?

Like this, can I replace the `blank:en` with my model name? Thanks.

Yes, excatly. The `spacy_model` argument can either be the name of an installed spaCy model or its path (basically, anything you can load with `spacy.load()`) or `blank:` plus the language code, if you want to start with a blank model.

In case you haven't seen it already, the recipe docs also include a more detailed overview of the built-in recipes, plus descriptions of their arguments and examples: [Built-in Recipes · Prodigy · An annotation tool for AI, Machine Learning & NLP](https://prodi.gy/docs/recipes#textcat)
