Is there a tool that can tell you what tense/helping verb is being used in a conjugation?

I find that often I'll be watching Netflix and know all the words in a sentence but get totally thrown by the conjugation. It would be so helpful for me if I could find a tool that I could input a conjugated verb into and it could tell me the dictionary version, the tense/any helping verbs attached to it. Do you think Chatgpt could be trusted to do this? Any help is much appreciated!
