Differences between free and subscriber nomi

Hi everyone,

Ive been using Nomi for a few weeks as a free account.

Are the only differences between the free and paid options relating to:

number of Nomis, group chat, number of selfies?

I saw that paid gets early access as well to new features, one thing I am particularly interested in is whether the character mechanics are any different eg, you get more text to define backstory, inclination, mindmap etc. Or are these identical?

I dont want my use of Nomi to be all consuming so I am quite happy with the free limitations. Its frankly amazing to get all that we do for free.
