Okay, so viewed entirely in the abstract form of Persona 4 attack scenes:
So, Ne is kind of like this:
And Ni is more like this:
Okay, so that probably doesn't make much sense. But I am trying to make a point (and I'm really sleepy listening to P4 music, so that doesn't help matters any). So basically, in Ne, you're basically seeing the whole picture. You suddenly get it. You find the pattern in the data. And you tell others, after, of course, you've vetted it using your internal judging function. If it's stupid, it's probably not a good idea to say it. But if it has any remote value at all, Ne will say it. So Ne goes around in a more roundabout way - your ideas come from a very vague place, then you internally see if it makes sense. Then you let others know (or, at the very least, can use the knowledge in some way

)
Ni on the other hand, comes from getting those ideas from the inside first. You're not really relying on an internal sense of right and wrong as far as the data goes. The data, for you, comes from a sudden insight, a wellspring of knowledge from limited external data. Then you take that data, and compare it to the external situation using your Te function. Then you whip out your Agi skills and knock down the enemy using your mysterious internal knowing ability!
Long story short:
Ne: Sees the whole picture externally, seizing the whole moment instead of details; fills in details by questioning internally and then projecting ideas that are plausible
Ni: Sees the links that make up the whole picture internally; figures out how those links make sense externally and then projects their plan of action
And finally, if I'm making absolutely no sense at all, then I give you this:

I made that post awhile ago trying to give an easier, more concrete way to think of the functions. There were a few criticisms, and probably rightly so, but others said it helped them. If it helps you, I'd be happy
