Is a Python API implemented for Interactive Learning?

Hi! I’m new here and I’m still learning, sorry if this is not the place for a question like this.

I’m trying to run interactive learning outside of the command line. Is it possible?

What I really want is to continue training a model on new entities, sentences and stories. Is there an API for that or do I have to retrain the whole model every time I add new data?

Interactive learning points me to believe I don’t need to retrain the whole model, but what would I have to do if wanted to build a custom interactive learning interface?
