Well, it’s not science fiction anymore.

How It Works

With Subtxt’s Muse, you’re the visionary. Speak your ideas, no matter how scattered or wild they may seem, and Muse takes care of the rest. It captures the heart of your narrative, ensuring every twist and turn, every character decision, remains thematically consistent.

No more guesswork, no more second-guessing. Just pure, creative freedom. Start a scene, build a world, or tweak a character’s journey—all by throwing ideas into the mix and letting Muse handle the complexity. Muse keeps track of your story’s DNA so you can focus on what you do best: being the storyteller.

The Subtxt with Muse Advantage

You’re not just crafting a story; you’re shaping an experience that’s deeply personal and true to your voice. With Subtxt, you remain in the driver’s seat, while Muse works as your personal story consultant—guiding you with insights steeped in real-world narrative theory. Muse doesn’t just spit out generic feedback; it respects your vision and amplifies your storytelling, staying true to your style every step of the way.

Your vision, your voice, your story, amplified by Muse's intelligent assistance.

"I'm convinced the new Muse in Subtxt Infinite is nearly psychic. All I have to do is feed it my stream of consciousness notes and it turns it into something organized and usable, which I can plunk into the Storyforming engine. It's magic. When I query it about my MC it's like it's picking the thoughts straight out of my head."

Why Subtxt is Different

Unlike standard AI systems that lean on incomplete, subjective frameworks like the Hero’s Journey or Save the Cat!, Subtxt with Muse is built on an author-based objective paradigm of story structure. This means it doesn’t just see the surface—it understands the deep, thematic underpinnings that make your story unique.

Muse is more than just AI. It’s the only tool that seamlessly bridges the gap between your ideas and flawless execution. With Subtxt, you’re not getting a biased, formulaic output. You’re getting responses that are intelligently aligned with the DNA of your story.

"+1 for Subtxt...Amazing execution. Jim is quietly and by himself building something more sophisticated than most AI startups right now.”

Insightful and Enlightening

A better collaborator

Subtxt with Muse is more than just an LLM, it's an AI packed with over 30 years of narrative expertise. Upload your most current draft, and instantly start finding ways to improve your work.

(Even if your work has been nominated for a Best Picture and Best Screenplay) 😄

Important

We NEVER train on the text of previous works (or your work). Anyone who knows even a little about narrative structure knows that training on the text is a recipe for disaster.

Instead, we train on the subtext of completed works. We align with the author's intention and purpose in writing their story.

And if you don't know what you want to say, we can help with that too.

When you write with Muse, you write with the world's leading expert in story structure and narrative theory—only this one is infinitely patient (and always available).

(and no, we don't think "The Holdovers" needs improving)

“Muse has successfully blown me away! Asking Muse questions about my script the same way I would ask a trusted friend after they just read it is a profound experience. The answers have exceeded what I expected, and the bar was already set pretty high. It's Narrative First-specific answers to my Narrative First-specific questions are much more accurate and insightful. I'm obsessed, Jim; this is exactly what I needed to help me create a kick-ass pitch deck for this movie. Thank you!”

Brandon Ravet, Screenwriter

Subtxt is not just for screenplays

Anyone who tells you that a novel has a different "structure" than a play, a musical, or a film hasn't really thought very deeply about how stories work.

We, on the other hand, have.

Go Deep

Embark on a deeper narrative adventure—where every story element means more.

At the heart of every memorable story lies a hidden force, a submerged power beneath the waves of written words. It's not the plot points or the characters that we see at first glance—it's the subtext, the profound ideas and emotions that resonate with us long after the story ends.

Above the Water: Storytelling

In the realm of storytelling, the visible part of the iceberg is just the beginning. Basic language models (like ChatGPT or Claude) may offer the structure of a narrative, but they dwell on the surface. Subtxt invites you to plunge beneath, into the world of subtext, where the true essence of your story lies.

Beneath the Surface: Subtxt

Subtxt and Subtxt Muse go beyond superficial storytelling, guiding you to the profound narrative structure that breathes life into your writing. Discover the depths of intent and meaning that transform a good story into a timeless journey.
