That’s not a PyTorch question, so you might won’t get the right answers here.
Having said that, you can expose the functionality of your models via an API. For example, I use Falcon 1 for that. Your API has to offer at least one endpoint to upload the content (e.g., /upload) that

listens to uploaded text files or links
processes the content (e.g., making a prediction using your trained models)
returns all the data needed to visualize the results

The you can build any kinde of Web frontend that uses the API. But again, I’m not a Web developer, and this is the wrong forum for this type of question :).
