I'm attempting to work on a "spiritual successor" to Dramatica Story Expert, a crazy story theory/brainstorming program of days gone by. Technically, Dramatica is still around, but they never made a 64-bit version for Macs, and both the Mac and Windows version have been tenaciously clinging to the trailing edge of technology for decades. (The Mac version somehow never got retina fonts. I'm not sure how you even do that.)
I started my program in Swift and SwiftUI, although for various reasons I'm starting to look at Dart and Flutter (in part because being multiplatform would be beneficial, and in part because I am getting the distinct feeling this program is more ambitious than where SwiftUI is at currently). It isn't a direct port of Dramatica by any stretch, instead drawing on what I've learned writing my own novels, getting taught by master fiction writers, and being part of writing workshops. But no other program that I've seen uses Dramatica's neatest concepts, other than Subtxt, a web-based, AI-focused app which has recently been anointed Dramatica's official successor. (It's a neat concept, but it's very expensive compared to the original Dramatica or any other extant "fiction plotting" program. Also, there's a space for non-AI software here, I suspect: there are a lot of creatives who are adamantly opposed to it in any form whatsoever.)
I don't think I'm planning to go open source, although I have to get through the whole "have an actual application to start letting people beta test" stage first. Even if it's a commercial program my thought is "pay a single price once, not a subscription," and probably under $100.
Arc Studio looks like it's a screenwriting program, which is a different animal, though. Have you tried out Fade In (https://www.fadeinpro.com), which is a $79 one-time fee? I haven't used it, I confess, but I hear great things about it. (I used the even cheaper Highland Pro for my one try at screenwriting so far, but that was a learning exercise.)
Fade In looks like a great option! I'll check it out.
I find selling commercial software to be really difficult, honestly I'd rather just release my projects for free versus dealing with someone complaining that it doesn't run right, etc.
If you have a mailing list or something I would be glad to sign up! I'll be your first customer.
