Normally, tag questions end with BE or an auxiliary verb and
a subject pronoun or there. Sometimes, however, other endings
are used. The most common one is probably right?. It can be
used with both affirmative ( + ) and negative ( - ) sentences:

He's a nice person, right?
He isn't a nice person, right?

She's coming with us, right?
She isn't coming with us, right?

There were at the party, right?
They weren't at the party, right?

She likes me, right?
She doesn't like me, right?

We remembered everything, right?
We didn't forget anything, right?

She's been here before, right?
She's never been here before, right?

You'd seen the movie before, right?
You hadn't seen the movie before, right?

He can fix my car, right?
He can't fix my car, right?

etc.

Sometimes correct? is also used in the same way, but it's
considerably more formal than "right?":

He's a nice person, correct?
He isn't a nice person, correct?

She's coming with us, correct?
She isn't coming with us, correct?

There were at the party, correct?
They weren't at the party, correct?

She likes me, correct?
She doesn't like me, correct?

We remembered everything, correct?
We didn't forget anything, correct?

She's been here before, correct?
She's never been here before, correct?

You'd seen the movie before, correct?
You hadn't seen the movie before, correct?

He can fix my car, correct?
He can't fix my car, correct?

In addition, don't you agree? is sometimes also used like
a tag ending (though it's rather formal and is appropriate
only when an opinion or judgment given):

He's a nice person, don't you agree?
He isn't a nice person, don't you agree?

She likes me, don't you agree?
She doesn't like me, don't you agree?
