Plot Factory
This one's pretty neat! You can use it either free, which allows you to write only one story no matter how many 'universes' you have, or upgrade to one of three tiers and unlocked various features. I tried the free version.
Plot Factory lets you create 'universes', which I really like! You can pick an image to represent each universe, give them a title, and a summary! Then you can add properties, laws, settings, themes, and anything else to the universe, which is pretty neat. Being able to move them around would be nice - put them into boxes, or color code them, would be helpful for keeping track, as at the moment it's just a column of text. But that's personal preference.
You can sort your stories by universe, as well. So if you write a few shorts for a certain dystopia, then you can have them all under that world. I like this! It lets you easily check that you're keeping it to the 'rules' you've already established for it, and add to them as you go. You're able to add an image and summary for each story but, whether I'm just blind or its locked behind a subscription, I couldn't figure out how to. (edit: you have to go to the 'general' tab, not 'write', and you can edit the summary, genres, and image for each story there)
A lot of features are behind subscriptions. Such as having your story read back to you, plotting your story out beat by beat within the story itself so you can easily view it, viewing multiple drafts, and making a chapter summary. However, you can still make notes next to your chapter, and it's workable without subscribing.
There's an in-app session word goal set, which is nice! That's always something to like. And I haven't seen it on any program before, but there's also a name generator! You can set gender, language, and popularity! Definitely a MAJOR plus for Plot Factory.
Once you set up your characters - there are characters sheets! There's an open spot for any text you want to write, as well as lines to fill out, though you can change the entry. There are 'comprehensive' sheets available to subscribers. - you can important them to any other story in the same universe! Same with places, objects, and elements.
PLOT FACTORY HAS TEMPLATES. They have the Three Act Plotting Structure, what they call Story Beats Plotting Template (it appears to be Save the Cat), and Story Premise Worksheet. These open as a single text document to fill out - if each one was broken up to acts/beats/etc to fill out it might be nice, less 'block of words', but that's personal preference and QOL, not something super important.
There's also a 'Plots' tab, but it's subscriber locked so I'm not sure what it is.
Also a general 'Notes' tab, where you can make little documents for whatever you need.
The statistics tab is great, and I really like it! You can set a word goal and it will tell you what % you are to it. You can also see how many words you've written each day on a graph, which can either be a blessing or a curse depending on if you're discouraged by seeing that. Also has a word count breakdown to show you how many words you have per chapter, so you can see if there are any with a lot more/less than the rest. It also shows you your overused words and phrases, which is useful!
Like Dabble, you can collaborate if you subscribe!
I'd say probably 7-8/10? Probably higher if you subscribe for the extra features.
