Writing with AI

Your Subscription


Subtxt is a subscription-based service for storytellers. The purpose of this subscription is both to support active development and improvement of the system, as well as make it possible to maintain access to cutting-edge artificial intelligence technology.

Subscription Tiers

There are two different subscription tiers for Subtxt's AI services:

  • Subtxt: This is the basic model used throughout the system.
  • Subtxt Pro: This is the upgraded model used where improved reasoning is required.

Subtxt uses OpenAI's services in order to deliver high-quality AI responses. The major difference between the two subscription tiers is the OpenAI model used. Subtxt uses GPT-3.5, with some exceptions. Subtxt Pro uses GPT-4.

Subtxt Tier

Purpose: The Subtxt subscription serves as the foundational tier for users beginning their journey in narrative understanding using the Subtxt app.

Ideal For: Beginners in narrative theory or users who prefer a straightforward, fundamental approach to story structuring.

  1. GPT-3.5 Only: With the Subtxt tier, you get exclusive use of the GPT-3.5 model for all of your narrative needs. While it's a highly capable model, it doesn't offer the added reasoning benefits you'd find with GPT-4.

  2. Approx. 9000 words per interaction: The context window for the Subtxt model is limited to 9,000 words, which is approximately the size of a detailed treatment or short story.

  3. Access to basic examples & analyses: We maintain a comprehensive and active database of narrative structures. The Subtxt tier has access to the fundamental and basic understandings of each of these examples.

  4. Single Muse Persona: You're restricted to a single Muse Persona that you can customize similar to Custom Instructions in ChatGPT.

Subtxt Pro Tier

Purpose: The Subtxt Pro tier caters to users seeking an advanced, more in-depth exploration of narrative concepts and storytelling techniques.

Ideal For: Experienced writers or individuals who desire a comprehensive and nuanced understanding of narrative theory.

  1. Choice of GPT-3.5 and GPT-4: The biggest perk here is the flexibility to toggle between the GPT-3.5 and the more advanced GPT-4 models. This allows for more nuanced storytelling, better reasoning skills, and overall better performance.

  2. Approx. 18000 words per interaction: Nearly doubling the capabilities of the Subtxt tier, Subtxt Pro opens up the context window to size of a feature-length screenplay or novella. This translates to better memory performance while working with Muse and other Subtxt AI services.

  3. Access to the full library of examples and analysis: The limited context of the Subtxt tier necessitates some truncation of the Subtxt library. The Subtxt Pro model enjoys full access to everything.

  4. Multiple Muse Personas: You have the liberty to work with multiple Muse Personas, which also includes special "Storytelling-specific" Personas that focus purely on Storytelling elements. By setting a Muse Persona to "Storytelling only," you maximize the ability to send more of your story text to the AI, without the addition of narrative structure or intelligence behind the scenes.

Transitioning Between Subtxt and Subtxt Pro

Many writers have found it beneficial to switch between the two models depending on what they're looking for. For insights into deep narrative structure, Subtxt Pro should be turned on. For quick summarizing or outlining, Subtxt will be more efficient.

Users can switch back and forth between the two by simply tapping on the currently selected engine model in the lower right-hand corner.

When you reach a maximum amount of messages under GPT-4, Subtxt will automatically downshift you into 3.5 and remove the Subtxt Pro label from your application. You can resume using GPT-4/Subtxt Pro once enough time has passed.

While most of Subtxt runs on GPT-3.5, including all Brainstorming AI interactions and Launch features, the "Teach Me a Complete Story" feature uses GPT-4 regardless of subscription on the step marked "Extract Four Throughlines." The rest of the steps within that feature all use GPT-3.5.

The price differential between Subtxt and Subtxt Pro reflects the feature set between the models, with Subtxt Pro offering more advanced capabilities for those looking to delve deeper into their storytelling.

By understanding and utilizing these features, you can enhance your experience with Subtxt Muse and better develop your story's structure and narrative elements.

Upgrading from Subtxt to Subtxt Pro Subscription

We understand that many of our users might be interested in upgrading from the Subtxt model (GPT-3.5) to our more advanced Subtxt Pro model (GPT-4). While we wish we could offer a seamless upgrade path, it's important to clarify that there is no direct way to upgrade from a Subtxt subscription to a Subtxt Pro subscription.

Why Is There No Upgrade Path?

The Subtxt Pro model (GPT-4) is significantly more advanced and, as a result, more expensive to run than the Subtxt model (GPT-3.5). This increased cost is reflected in the Subtxt Pro subscription fees. Because of this substantial difference, we are unable to offer an upgrade path that would simply pro-rate the difference in costs.

How to Upgrade to Subtxt Pro

If you're interested in experiencing the capabilities of the Subtxt Pro model, here's how you can make the switch:

  1. Cancel Your Current Subtxt Subscription: Log in to your Subtxt account, go to the 'Subscription' section, and cancel your Subtxt subscription. Please note that you will still have access to the Subtxt model until the end date of your current billing cycle.

  2. Purchase a Subtxt Pro Subscription: Once your Subtxt subscription is canceled, you can go ahead and purchase one of the Subtxt Pro subscription options, available on a monthly or yearly basis.

We apologize for any inconvenience this might cause and appreciate your understanding as we aim to offer you the best narrative technology out there.

AI Models Comparison: Subtxt vs. Subtxt Pro

Objective: To demonstrate how different AI models interpret the same narrative information, particularly focusing on the "You and I" argument between the main and obstacle characters.

Subtxt: This model provides clear and straightforward explanations of narrative concepts. It is suitable for users at the beginning of their narrative journey, offering a basic yet solid understanding of the "You and I" argument in storytelling.

When asked to provide the "You and I" argument often found between the two principal characters of a complete narrative, Subtxt set to Subtxt provided the following:


Centaur stood with a furrowed brow, his eyes fixed on Skylar. "We're actually the same, you and I," he said, his voice tinged with frustration.

Skylar raised an eyebrow, her arms crossed. "How can you say that? You're all about proaction, while I believe in the power of reaction. We couldn't be more different."

Centaur shook his head. "But that's just it. We both let our beliefs dictate our actions, even when it might not be the best course of action. You react out of fear of failure, and I proact out of a need for control. We're both driven by our own insecurities."

Skylar's eyes narrowed. "I don't act out of fear. I act out of determination to prove myself."

Centaur sighed. "And I proact out of a need to avoid feeling powerless. We're both letting our past experiences control us, and it's causing more harm than good."

Skylar's fists clenched. "I refuse to believe that. My reaction has driven me to success, not harm."

Centaur took a step closer. "But at what cost, Skylar? Your relentless drive to react has pushed you to the brink of burnout. And my need for proaction has led me to make decisions that hurt others. We need to find a balance, or we'll both end up losing everything."

Skylar's resolve wavered as she considered Centaur's words. Perhaps there was a middle ground between reaction and proaction that could lead them both to a better outcome.

Subtxt Pro: Exhibits a sophisticated approach to narrative analysis, highlighting subtleties in character interactions and thematic layers. Its advanced interpretation aligns with the needs of experienced storytellers, showing a deeper, more nuanced grasp of complex narrative dynamics.

When provided with the same exact information given to the Subtxt model, the Subtxt Pro version of Subtxt responded with something more closely aligned with an advanced writer (with advanced reasoning capabilities):


"You and I are so much alike," Skylar said, her voice echoing in the cavernous space of the parallel universe. She was standing face to face with Centaur, her eyes reflecting the ethereal glow of the universe around them.

Centaur, a being of logic and action, tilted his head, his gaze steady on Skylar. "We may share similarities, Skylar, but our approach to life is fundamentally different."

Skylar's heart pounded in her chest. She was a journalist, a seeker of truth, a reactor to events. She thrived on the adrenaline of the unexpected, the thrill of the chase. But here, in this parallel universe, her usual tactics were failing her. She was up against a sorcerer, a mythical creature that defied all logic and reason.

"I react to situations, Centaur," Skylar said, her voice steady despite the fear gnawing at her. "I wait for the story to unfold, for the truth to reveal itself. But you...you believe in taking action, in shaping the narrative."

Centaur nodded, his gaze never leaving Skylar's. "Yes, I believe in proaction. In this universe, waiting for things to happen can be deadly. We must act, Skylar. We must confront the sorcerer."

Skylar felt a chill run down her spine. She was not used to this, to taking the lead, to shaping the narrative. But she knew Centaur was right. They were in a parallel universe, facing a sorcerer and an evil twin dragon. Waiting for things to happen was not an option.

"But what if we fail, Centaur?" Skylar asked, her voice barely a whisper. "What if our actions lead to more harm than good?"

Centaur reached out, placing a comforting hand on Skylar's shoulder. "We may fail, Skylar. But we will never know unless we try. And if we do fail, we will learn from it and try again. That is the essence of proaction."

Skylar took a deep breath, her mind racing. She was a reactor, not a proactor. But here, in this parallel universe, she had to adapt. She had to learn to take action, to confront her fears, to shape her own narrative. And with Centaur by her side, she knew she could do it.

"You're right, Centaur," Skylar said, determination seeping into her voice. "We are alike. And together, we will confront the sorcerer. We will shape our own narrative."

And with that, Skylar and Centaur set off, ready to face the challenges that awaited them in the parallel universe. Their journey was just beginning, but they were ready to face it head-on, together.

The choice between Subtxt and Subtxt Pro subscriptions depends on the user's level of expertise and their desired depth of narrative understanding. Subtxt is suitable for those new to narrative theory, while Subtxt Pro offers advanced insights for seasoned writers. Both tiers, supported by the respective capabilities of GPT-3.5 and GPT-4 Turbo, provide valuable tools for narrative exploration and storytelling mastery.

Managing Your Subtxt Subscription

To manage your Subtxt Subscription, including upgrading or downgrading accounts, putting them on hold or canceling them, or even downloading of invoices--please visit your Billing page within your personal Settings (the "person" icon in the upper right-hand corner of the application).

To directly access the billing portion of your account (including all listed above), select Manage My Billing. Doing this will take you to a different site that handles accounts in Subtxt. Once updated, that site will return you to Subtxt with your account updated.

Working with the Writing Process

The writing process is one of development, followed by execution, followed by more growth, and so on and so on. Write, rewrite, write, rinse, repeat.

Subtxt honors this process by making it easy for the writer to start and stop their subscription to our service. Engage Subtxt for as long as it takes for you to get a firm idea of what story is about, then pause while you get down to the business of actually writing.

Stopping a subscription is really just putting Subtxt on hold. When you finish, Subtxt retains all your stories and keeps them safe for when you’re ready to return—whether to dive deeper into the story you’re working on now or when you’re feeling the itch to develop something new.

Credit When Stepping Away

Cancelling does not credit back any remaining subscription time. If you purchased a yearly subscription, then you have access to Subtxt for that calendar year regardless of stopping or starting. If you cancel the yearly subscription, then when you start up again you will have to purchase a new subscription. The same procedure applies for monthly subscriptions.

If you put your subscription on hold before the end of your current pay period, Subtxt will continue to work until the very last day. In other words, if you sign up for a yearly subscription, then promptly put your subscription service on hold minutes later, Subtxt will continue to work for the next 365 days.

No 10-Day Trial Period

At Subtxt, we understand that many SaaS applications offer an introductory trial period. However, due to the heavy integration of AI features within our platform, we are unable to provide such a trial. Our powerful application allows users to develop complete stories in just a few days, making a trial period incompatible with our platform.

Purchase Parity Option

We do offer price parity for those experiencing financial distress or for those who live in countries where a subscription to Subtxt is unaffordable. The purchase-parity option is available for Subtxt's Subtxt tier only and on a limited basis. For approval, please contact us directly.

Alternate Forms of Payment

A subscription to Subtxt requires a credit card. If you, for some reason, do not have access to a credit card but would prefer to pay through alternate means (PayPal, etc.) please contact us directly. We are able to set up alternate methods of payment for those who need it. Note that the process is manual, so it does take a bit longer to set up.

You can contact us directly through in-app Support by selecting the Support button at the top of the page (the "life-preserver" icon).

Benefits of Continuing Your Subscription

Subtxt is more than just an application—it's an evolving tool for writers of all levels. Our system is consistently updated with new narrative structures added weekly, and our extensive collection of Storytelling Suggestions continues to grow exponentially, making it an indispensable resource for your creative process.

One of the key advantages of maintaining your subscription is instant, always-available access to Subtxt Muse. This powerful feature provides ongoing support throughout your writing process, instantly offering insights and suggestions whenever you need them. With Subtxt Muse, you'll find that your understanding of narrative structure deepens and your storytelling skills become sharper.

While you’re free to start and stop anytime, we strongly suggest staying with Subtxt. It's not just about access to an ever-growing library of resources—it's about fostering your growth as a writer and enhancing your appreciation of the art and science of narrative structure.
