Regex to match variations I am: I, Im, Iam, I

I am trying to create a regex that can match different variations of a string. Specifically I am (with \s+

two words dividing), I, Im and Iam.

I tried to do it here, but it doesn't seem to work: I\s+?a?'?m

make white space, a and 'optional.

How would I do it correctly?

\bI'?\s*a?m\b

You can try this. See demo.

You shouldn't put ?

after +

because it doesn't match your text unless it contains a space, for example Im

. Use ?

after +

or *

Appropriately just when you want a non-greedy match.

^I\s?a?'?m$
