No, brackets parenthesise text such that the sentence should read just the same, i.e. grammatically complete, with the parenthesised section removed. Remove that section from your example and the comma left behind would be incorrect.

I might suggest altering the sentence structure such that brackets are not required though, e.g.,

Check out our new directory, created by people, for quick and easy access to information.

or this

Check out our new, people-created directory, for quick and easy access to information.
