Fountain+ is a free suite of screenplay writing tools for writers who'd rather draft in Google Docs than learn another editor. The Fountain+ Exporter is a Google Docs add-on that reads Fountain markup from your Doc and exports it to Final Draft .fdx, FadeIn, PDF, plain TXT, or clean Fountain.
The Fountain+ Screenplay Checker & Pre-Coverage is the browser-based companion. Drag in a Fountain, FDX, PDF or Mangaplay file and get an instant screenplay coverage report โ scene breakdowns, character statistics, location reports, and technical factors, downloadable as a PDF.
Everything runs locally; files never upload. Built for screenwriters prepping a draft, indie filmmakers scoping a shoot, manga creators tracking panel density, and assistants doing first-pass coverage.

Fountain+'s answer
I'm Pistol Taeja. I started in 2020 making manga and screenplays โ got tired of breaking my flow to format scripts. Fountain+ began as my own screenwriting software for me; Mangaplay Studio came next when I needed panels too. Hand-built tools, no venture money, defending steel over slop.
Fountain+'s answer
Because the others either visually reformat your Doc and stop, cap you at 15 pages, or drag you into a separate SaaS. Fountain+ is a true Fountain to Final Draft converter โ Docs in, industry file out. Fourteen languages. No account. No AI lock-in. No monthly bleed.
Fountain+'s answer
It's the only free screenplay tool that lives inside Google Docs and walks out with a real .fdx, .fadein or PDF โ no upload, no cap, no second editor. I built it because I was sick of writing in one place and exporting from another. Comic and manga pages included.
Fountain+'s answer
Working screenwriters, comic and manga writers, and Google Docs natives who refuse to switch editors just to hit "export." If you already draft in Docs and need Final Draft FDX export without paying Final Draft prices, you're who I built it for. Pros, hobbyists, and writers' rooms alike.
Fountain+'s answer
Pure JavaScript (ES2022+) with JSDoc types, Bun as runtime and bundler, parses the Fountain spec plus my Mangaplay extension. The Google Docs add-on is Apps Script. Everything is a browser-based screenplay converter โ your file never uploads. Mostly Open Source on Github
Fountain+'s answer
Honestly? Independent screenwriters, manga creators, and the long tail of Google Docs writers who found it through search. I'm chasing 100,000 downloads across my utilities by way of word-of-mouth, not enterprise logos. The best free screenwriting software wins users one writer at a time โ that's the bet.
