I don't think a comparison between amount of space usable/user (like in Evernote) and max words/day (your freemium?) is fair. If Evernote limited based on bandwidth/day or something like that or your model was total # of words a free account can use, then perhaps the comparison would be more fair. I think the problem with a max words/day is that the customer will limit their dependence to that maximum. You need the customer in a mindset where they'll only be concerned about the free plan's limits by the time they are dependent on the product.
right, I agree. I was using evernote moreso because 1) I was writing the post in evernote at the time so it was the first thing I thought of and 2) they have extremely low costs and require a decent amount of time to convince a user to convert to a paying user (they fully need to incorporate evernote into their workflow before converting).
My product (and this is in no way a comparison on product value to evernote) produces keyword analysis results nearly immediately, so the value can be realized a lot sooner and the user can incorporate my product into their workflow a lot sooner than something like evernote.
Also, as Evernote limits by total storage space in the free plan, it's comparable to what we used to do with total keywords for a free trial (before our freemium).
