Both recipes are indeed similar. The difference are explained in more detail in the [textcat.correct docs](https://prodi.gy/docs/recipes#textcat-correct) and the [textcat.teach docs](https://prodi.gy/docs/recipes#textcat-teach) but the main difference is that in the base behaviour the `teach` recipe has a model in the loop that updates as you give it labels while the `correct` recipe does not.

That said, you can configure `textcat.correct` to also allow the model to update _and_ you can configure a `--threshold` to tune how examples are pre-selected for annotation. The `textcat.teach` recipe, on the other, allows for a `--patterns` parameter. This allows you to supply a path to match patterns file to filter out examples containing terms and phrases. The matched spans are also highlighted when labelling.
