Three starting points

The creative work is yours. Always.

FluidScriptr is a translator, not a ghostwriter. You bring the story — the idea, the manuscript, the draft you’ve been shaping. It handles the format. Whether you’re starting from scratch or finishing something you’ve lived with for years, FluidScriptr meets you where you are.

01

I have a story idea

Answer six guided questions about your story — genre, protagonist, inciting incident, stakes, antagonist, climax. FluidScriptr builds a Story Bible and writes your full manuscript from scratch.

Idea → Manuscript → Format
02

I have a finished manuscript

Upload your novel or story (PDF or DOCX). FluidScriptr reads the whole thing, builds a Story Bible, and converts it into a screenplay or any other format — with your voice intact.

Manuscript → Any Format
03

I have pages to polish

Upload existing pages and FluidScriptr enhances them — tightening pacing, sharpening dialogue, and improving structure — all while preserving your original voice and style.

Draft → Enhanced Draft
The engine

It reads your story before it touches a single word.

Most tools process page by page — so chapter three doesn’t know what happened in chapter one. Characters drift. Voice flattens. The output reads like an imitation of your book, not your book.

FluidScriptr works differently. Before it generates anything, it builds a Story Bible — a complete map of your characters, arcs, voice, and themes. Every line it produces is anchored to that map.

Think of it the way you’d think of a great adapter: someone who reads your entire manuscript, understands what makes it yours, and then translates it — faithfully — into a new form. That’s not replacing your creativity. That’s respecting it.

What you get

One story. Every format it needs to be.

FluidScriptr covers the three things writers actually need: a screenplay to pitch, a polished manuscript to publish, and a tightened draft to submit.

Screenplay

Industry-standard format from your manuscript or idea. Proper sluglines, action, dialogue — ready to pitch or produce.

Fountain .fdx PDF

Manuscript

Publish-ready prose in Times New Roman, double-spaced, standard margins. Submission-ready from day one.

DOCX PDF RTF

Enhanced Draft

Take your existing pages and sharpen them. Better pacing, tighter dialogue, cleaner structure — still unmistakably yours.

DOCX PDF

Common questions

Things writers ask.

Do I need a finished manuscript to use FluidScriptr?
No. FluidScriptr has three starting points: upload a manuscript, answer six story questions to generate one from an idea, or upload existing pages to enhance. You can start with nothing but an idea.
What is the Story Bible?
The Story Bible is a structured analysis of your story — characters, arcs, voice, tone, and themes — built before any output is generated. Every scene FluidScriptr writes is anchored to this map, so nothing drifts and your voice stays consistent from page one to the end.
Which output formats does FluidScriptr support?
Screenplays export in Fountain, Final Draft (.fdx), and formatted PDF. Manuscripts export as DOCX, PDF, and RTF — Times New Roman, double-spaced, one-inch margins — submission-ready from the first export.
Do you store or train on my manuscript?
No. FluidScriptr processes everything locally in your browser session. Your API key is stored only in your browser, uploads are not retained, and your work is never used for model training. What you write stays yours.
What AI model does FluidScriptr use?
FluidScriptr runs on Claude (Anthropic) via your own API key. You bring the key — FluidScriptr brings the workflow. This keeps your costs transparent, your data private, and your content off shared infrastructure. Typical usage costs a few cents per conversion.
