Looking for a script processor that's completely foss and maintained
It seems every good option is paid, and all others are either discontinued (trelby, fountain) or filled with commercial and AI tools (Story Architect)
This is weird and discouraging, coming from the novel world where you could use a plain markdown editor and export it to epub/pdf/whatever you need. Anyone know of something better for screenwriting?
There is probably something LaTeX based. I doubt you will find any writing tools specifically marketed for screenwriting in the FOSS world if they could just as well be used for dozens of other writing tasks.
