​Inc authority legit?

I’ve been thinking about using Inc Authority to create my LLC & while the thought of free services is enticing, I don’t know if I should go for it.

I’ve heard they have a good reputation for formation accuracy, however, I still need some reassurance regarding some aspects. Can they help with a funding/business credit analysis? Do they offer tax planning consulting services?

If yes, are these services to be paid for separately or are they part of the free incorporation package? Feedback from an existing user would be appreciated.
