The complete guide to writing incredible erotica, romance, and adult fiction with AI.
Whether you're starting your first story or your fiftieth, this guide will help you get the most out of every feature.
In This Guide
Getting Started
SmutWriter is a full AI writing workspace built specifically for adult fiction. Think of it as having a professional co-author who never judges, never censors, and is available 24/7.
The best results come from working in steps rather than just jumping straight into writing. Here's the recommended workflow that experienced users swear by:
- Create a project for your story
- Build your Story Bible with characters, world, and plot details
- Start chatting with the AI to co-write your chapters
- Review and refine using the editor
This step-by-step approach gives the AI the context it needs to write consistently great content that stays true to your vision. Let's walk through each step.
Setting Up a Project
Everything in SmutWriter lives inside a project. A project holds all your chapters, Story Bible entries, notes, and uploaded files together in one place.
Create your first project
When you open the writing workspace for the first time, you'll be asked to create a project. Give it a name — something like "Dark Fae Romance" or "Space Station Erotica."
Add a description (optional)
Open the Projects panel (the folder icon in the sidebar on desktop, or tap the project name at the top on mobile). You can add a short description to remind yourself what the project is about.
Switch between projects
If you have multiple stories going, switching is easy. On desktop, click the folder icon in the left sidebar to see all your projects. On mobile, tap the project name at the top of the screen — a dropdown will show all your projects.
One project per story
Keep each story or series in its own project. This way, the AI only sees the context that's relevant to what you're writing and won't mix up details between different stories.
Your Story Bible
This is the single most important step for great AI writing
The Story Bible is your project's knowledge base. It's where you define your characters, world, locations, factions, lore, and plot. The AI reads your entire Story Bible before writing, so the more detail you put in, the better your output will be.
What to include in your Story Bible
Characters
Name, appearance, personality, backstory, quirks, relationships, kinks, speech patterns, motivations
Locations
Settings where scenes take place — describe the atmosphere, sensory details, and mood of each place
Plot Arcs
Major story beats, the arc of your romance/tension, key turning points you want to hit
Lore & World
Rules of your world — magic systems, technology, social norms, cultural attitudes toward intimacy
Factions
Groups, organizations, families — their goals, rivalries, and dynamics
Items
Important objects — enchanted items, heirlooms, anything that plays a role in your story
How to add Story Bible entries
Open the Story Bible panel
Click the book icon in the left sidebar (labeled "Story Bible"). This shows all your current entries.
Create an entry
Click the + button at the top. Type a name (e.g., "Elena Blackwood" or "The Crimson Tower") and press Enter. The entry opens in the editor.
Fill in the details
Write as much as you want in the description field. The more detail, the better. Don't worry about formatting — just get the information down. Think of it as notes to your co-author.
Character bibles make the biggest difference
For each character, include their physical appearance, personality traits, speech patterns, emotional vulnerabilities, and what they're like in intimate scenes. When the AI knows your character deeply, the writing feels authentic instead of generic.
Reordering and organizing
You can drag and drop entries in the Story Bible panel to reorder them. Hover over any entry to see options to rename or delete it.
Uploading Files & Smart Import
Already have a story bible, character sheets, or manuscript written elsewhere? You can upload them directly and let the AI import everything for you.
Uploading a file
Open the Files panel
Click the paperclip icon in the left sidebar. This is your project's file manager.
Upload your file
Click the upload button and select your file. Supported formats include PDF, TXT, Markdown, Word documents (.docx), CSV, and JSON.
Smart Import — AI-powered file parsing
This is where it gets magical. After uploading a file, hover over it and click the sparkle icon. The AI will analyze your file and automatically:
- If it's a manuscript or story — create individual chapters from it
- If it's reference material (character sheets, world notes, etc.) — create Story Bible entries from it
After importing, it will ask if you want to remove the original file to keep things tidy.
Upload your existing story bible
If you have character descriptions, world-building notes, or plot outlines in a document, upload and Smart Import them. In seconds, they'll become organized Story Bible entries that the AI can reference while writing.
File size
For best results with Smart Import, keep individual files under a reasonable size. If you have a very long manuscript, consider splitting it into parts before uploading.
Writing Chapters
Chapters are where your actual story lives. You can write directly in the editor, let the AI create chapters for you through chat, or do a mix of both.
Creating chapters manually
Open the Chapters panel
Click the open book icon in the left sidebar.
Add a new chapter
Click the + button, type a title, and press Enter. The chapter opens in the editor ready for writing.
Write and edit
The editor has a full formatting toolbar — bold, italic, headings, lists, alignment, font choices, and line spacing. Your work saves automatically as you type.
Letting the AI create chapters
When you're chatting with the AI in the workspace, it can create chapters directly. Just tell it something like:
"Write chapter 1 — Elena arrives at the tower for the first time."
"Create a new chapter where they finally give in to the tension."
"Write the confrontation scene we discussed. Make it 2000 words."
The AI will propose the chapter as a suggestion. You'll see a banner in the workspace where you can preview, accept, or reject it before anything is saved. More on this in the AI That Takes Action section.
Organizing chapters
Drag and drop chapters in the sidebar to reorder them. Hover over a chapter to rename or delete it. You can also view all your chapters at a glance using the Outline view, which shows each chapter as a card with its title, word count, and status.
AI Co-Authoring (Chat)
The AI chat is where the magic happens. You can talk to the AI naturally — describe what you want, ask for ideas, request rewrites, or just say "keep going" and let it flow.
Where to find the chat
- Inside the workspace — click the chat bubble icon at the bottom of the left sidebar, or tap Chat in the bottom tabs on mobile. This is the best way to use chat because the AI can directly interact with your project.
- Standalone — go to /chat for a full-screen chat experience. Great for quick brainstorming.
Quick action buttons
Above the input box, you'll see shortcut buttons for common requests:
Describe More
Makes the next part more vivid and detailed
Increase Heat
Turns up the intensity and spice level
Next Chapter
Moves the story to the next scene
Visualize Scene
Creates a rich visual description you can use with image generators
Tips for great AI conversations
- Be specific about what you want. Instead of "write a scene," try "Write a slow-burn scene where Elena and Marcus are trapped in the library during a storm. Focus on the tension and near-touches. 1500 words."
- Give direction, not just prompts. You can say things like "focus more on dialogue here" or "describe the setting before they interact" or "make this grittier."
- Iterate freely. If something doesn't land right, just say "rewrite that but make it more intense" or "change it so she's the one who initiates."
- Use the Story Bible. The AI automatically reads your Story Bible when chatting in the workspace. The more entries you have, the more consistent and on-character the writing will be.
Start a new chat when quality drops
If the AI's writing starts feeling repetitive, generic, or off-track, start a new chat. Long conversations can cause the AI to lose focus. Starting fresh gives it a clean slate while still having access to your Story Bible and memories. Think of it like starting a new writing session — the AI comes back refreshed.
AI That Takes Action
When you chat with the AI inside the workspace (not the standalone chat page), it gains the ability to directly work on your project. It can create chapters, update your Story Bible, and more — all while you stay in control.
What the AI can do
The suggestion system — you're always in control
The AI never writes directly into your project without your permission. Instead, it proposes changes as suggestions:
- You ask the AI to write or change something
- A suggestion banner appears in the editor with the proposed changes
- You can preview exactly what will change
- Click Accept to apply it, or Reject to dismiss it
If the AI suggests multiple things at once (like creating several bible entries), you can accept or reject each one individually, or use "Accept All" / "Reject All."
Example workflow
"Read chapter 3 and write chapter 4 — they should finally confront each other about the betrayal. Make it emotionally raw. End with an unexpected kiss."
The AI will read your chapter 3, consider your Story Bible, and create chapter 4 as a suggestion. Preview it, accept it, then keep going.
Muses — AI Writing Personalities
Muses are different AI writing personalities that change how the AI writes. Think of them as different co-authors, each with their own style and strengths.
Built-in Muses
SmutWriter comes with five built-in Muses available to everyone:
The Storyteller
Novelistic, rich descriptions, balanced dialogue. Great all-rounder for romance and fantasy.
Vivid Desires
Explicit, visceral, graphic, fast-paced. Best for erotica and intense scenes.
Romantic Whisper
Poetic, emotional, slow-burn tenderness. Perfect for sweet romance and building tension.
The Dark Muse
Gritty, intense power dynamics, psychological depth. Ideal for dark romance, BDSM, and mafia themes.
The Companion
First-person, interactive, seductive. Designed for roleplay and intimate conversation.
Creating your own Muse
Premium users can create custom Muses tailored to their writing style. Go to the Muses page and click "Create Muse." You can set:
- Name & avatar — give your Muse an identity
- Personality — describe how it should behave (e.g., "playful and teasing, loves building tension")
- Writing style — describe the prose (e.g., "flowery and descriptive, emphasis on emotion and sensory detail")
- Genres — pick which genres it's best at
- Custom instructions — advanced users can write detailed instructions for exactly how the AI should write
Community Muses
When creating a Muse, you can toggle Make Public to share it with the community. Check out the Discover tab on the Muses page to browse Muses created by other writers. Found one you like? Click "Use This Muse" and you'll jump straight into writing with it.
Switching Muses
In the chat, you'll see a Muse selector dropdown at the top. Switch Muses anytime to change the AI's writing personality. You can even switch mid-story if you want a different tone for different scenes.
Match the Muse to the scene
Use "Romantic Whisper" for the tender build-up, then switch to "Vivid Desires" for the climactic scenes. Or create a custom Muse that blends exactly what you want.
Memory — Teaching Your AI
Memory lets the AI remember important facts across all your chats. Unlike the Story Bible (which is per-project), memories are global — they follow you everywhere.
What to use memory for
- Your personal writing preferences ("I prefer third-person limited POV")
- Recurring style notes ("Always use Oxford commas" or "Avoid purple prose")
- Character details that span multiple projects
- Things the AI should always or never do
How memory works
The AI automatically picks up important details from your conversations and saves them as memories. You don't have to do anything — it learns as you write together.
But you can also manage memories manually:
Open the Memory manager
Click the gear icon in the sidebar to open Settings, then click Manage next to Global Memory. You can also access it from the brain icon in the chat.
Add a memory
Type anything in the text box and click Save Memory. You can also upload a file (PDF, TXT, DOCX) — the text will be extracted for you to review before saving.
Manage existing memories
Each memory can be edited, toggled on/off (deactivated memories aren't sent to the AI), or deleted. Use Clear All to start fresh.
Memory vs Story Bible
Use the Story Bible for project-specific details (this character, this world, this plot). Use Memory for preferences and instructions that should apply to all your writing across all projects.
Story Mode vs Companion Mode
SmutWriter has two distinct writing modes that change how the AI approaches your conversation.
Story Mode
The default mode. The AI writes collaborative third-person fiction — like having a skilled co-author. Produces rich, novelistic prose with detailed descriptions, natural dialogue, and proper scene structure.
Best for: Writing novels, short stories, multi-chapter erotica, romance fiction
Companion Mode
The AI responds in first-person as an interactive partner. Reactive, immersive, and uses *action* formatting. Designed for real-time roleplay and intimate conversation.
Best for: Roleplay, interactive scenarios, one-on-one intimate chat
You can switch between modes using the mode toggle in the chat input area (the book icon for Story Mode, chat bubble for Companion Mode). Switch anytime — even mid-conversation.
Notes & Research
Notes are your scratchpad. Use them for anything that doesn't fit neatly into chapters or the Story Bible — research, brainstorming, plot ideas, scene sketches, or random inspiration.
Creating and organizing notes
- Click the sticky note icon in the sidebar, then + to create a note
- Notes use the same rich text editor as chapters — full formatting, fonts, lists, etc.
- Add labels to categorize notes (click "Add label..." in the editor). Labels appear as filter buttons at the top of the Notes panel
- Upload images or documents directly into a note using the Upload button in the editor toolbar
Searching Your Project
Need to find where you mentioned a character's eye color? Or which chapter has the confrontation scene? The search feature has you covered.
- Click the magnifying glass icon in the sidebar (desktop) or the search icon in the top header (mobile)
- Type anything — results appear instantly as you type
- Search covers chapters (title, summary, and full text), Story Bible entries (name, description, and aliases), and notes (title, label, and full text)
- Click any result to jump straight to it in the editor
Ask the AI to search for you
In the workspace chat, you can ask the AI to search your project too. Try: "Where did I first mention the prophecy?" or "Find all scenes where Elena and Marcus are alone together."
Editor Tips & Tools
Focus Mode
Click the maximize icon in the bottom-right of the editor to hide the sidebar and write distraction-free. Press Escape to exit.
Sprint Timer
The editor has a built-in writing timer in the bottom bar. Hit play to start timing your writing session — great for writing sprints or tracking productivity.
Word Count
Live word count is always visible at the bottom of the editor. Keeps updating as you type.
Keyboard Shortcuts
Ctrl/Cmd+S to save. Ctrl/Cmd+B for bold. Ctrl/Cmd+I for italic. Standard shortcuts you already know.
Multiple Tabs
Open multiple chapters, bible entries, and notes as tabs across the top. Click any tab to switch between them. Great for referencing one chapter while writing another.
Font & Formatting
Choose from multiple fonts (Georgia, Times, Merriweather, and more), adjust line spacing (1.0x to 2.0x), and use headings, lists, blockquotes, and text alignment.
Pro Tips for Better Writing
These tips come from the SmutWriter community — writers who've figured out what works best.
1. Build your Story Bible first
The single biggest quality improvement is having a detailed Story Bible before you start writing. Characters with depth, worlds with rules, and plots with direction make the AI output dramatically better.
2. Start new chats regularly
If the AI starts repeating phrases, losing character voice, or producing generic content, start a fresh chat. Your Story Bible and memories carry over automatically, so you lose nothing but the conversation weight.
3. Be a director, not just a reader
The best results come from guiding the AI like a director guides an actor. "Slow this scene down," "make her more hesitant here," "less dialogue, more internal thought." The more you direct, the better the output.
4. Use memories for your writing rules
Save your universal writing preferences as memories: "Never use the word 'orbs' for eyes," "Always end chapters on a hook," "My stories use British English." The AI will follow these across all chats and projects.
5. Mix AI and manual writing
You don't have to choose one or the other. Many writers let the AI draft scenes, then edit by hand in the editor. Or write key passages yourself and let the AI fill in transitions and descriptions.
6. Match the Muse to the moment
Switch Muses between scenes for tonal variety. Use a tender Muse for emotional beats and a vivid one for intense scenes. Or create a custom Muse that matches your exact voice.
7. Let the AI read before it writes
Before asking the AI to write the next chapter, ask it to read the previous one first. This gives it immediate context and produces more consistent continuations. Just say: "Read chapter 5, then write chapter 6."
8. Use notes for planning
Before diving into a new arc, create a note outlining the scenes you want. Use labels to organize your notes by act or storyline. This helps you stay on track even across long projects.
Frequently Asked Questions
Is SmutWriter free to use?
Yes! You can start writing for free with a few messages. Premium subscribers get unlimited messages, custom Muses, priority processing, and more.
Is my writing private?
Your stories, projects, and chats are private to your account. We don't read, share, or use your content for training.
Am I responsible for the content I create?
Yes. SmutWriter is a tool — you are responsible for the content you write and how you use it. Please review our Terms of Service for full details.
Why did the AI start writing worse after a long conversation?
Long conversations can cause the AI to lose sharpness. Start a new chat — your Story Bible and memories carry over automatically, so the AI still knows everything about your story.
What's the difference between Story Bible and Memory?
The Story Bible is per-project — characters, locations, lore for a specific story. Memory is global across all projects — your writing preferences, style rules, and things you want the AI to always know.
Can I use SmutWriter on my phone?
Yes! SmutWriter has a full mobile interface with bottom navigation tabs and a project switcher at the top. You can also install it as an app from your browser.
How do I get the AI to write longer passages?
Be specific about length in your prompt: "Write a 2000-word chapter" or "Make this scene at least 1500 words." You can also click "Describe More" to get the AI to elaborate on its last output.
