riddle - If you only have half of me, then I am of no use

People think a part of me is sticky, but I'm not.
I do have a sticky friend though.

I can create almost anything,
but I'm not very creative.

After I have done my thing, you can't tell that I did it.
To be honest, it wasn't my creation to begin with.

What am I?

Answer

You are:

Ctrl+C and Ctrl+V (Copy and Paste)

If you only have half of me, then I am no use

Why copy something if you can't paste it? And you can't paste something without a copy

People think a part of me is sticky, but I'm not

Copy doesn't do anything on itself.

I do have a sticky friend though

Copy is best friends with Paste.

I can create almost everything

You can copy pretty much all text

But I'm not very creative

But copy doesn't generate anything by itself

After I have done my thing, you can't tell that I did it

You can't distinguish between copied text and the original

To be honest, it wasn't my creation to begin with

Of course it wasn't. It's a copy!

Hint:

It's a copy of the original
