If I am able to do something in the future should I use "I am able to do it in the future" or "I will be able to do it in the future"? Is there a difference?

As you probably already know, there is a difference between saying I am able to do something, and I will be able to do something. The first says I can do it now, while the second says I can do it some time in the future.
However, we have to re-evaluate this when you add an adverb of time that is already in the future. If I say I am able to do something in the future, it's not clear whether I can or can't do it now. The default assumption is I can't do it now, otherwise I would just say that I can do it. For example:
When can you mow the lawn?
I can do it. (I can do it now)
I am able to do it this afternoon. (I can't -- or I don't want to -- do it now)
I will be able to do it this afternoon. (I can't do it now. Or I don't want to)
The practical result is that these two forms have the same meaning, even if they approach it in different ways.
Can we go see a movie sometime soon?
I am able to go tonight / I will be able to go tonight.
Either way, same meaning. Native speakers use these forms interchangeably.
If you are talking about the presence of someone or something, "I will be with you" speaks of a time of waiting, whereas, "I am with you" says no waiting is necessary. They are not the same.
