who they are.

Dark hair that falls past her shoulders in loose waves. Brown eyes that hold steady when most people look away. A scar across her left knuckle she never explains. Olive skin with a warmth that catches light in a way that makes people look twice. Sharp jaw. A mouth that suggests she's about to say something she shouldn't.
AI fiction has a character problem.
Your characters deserve more than a sentence.
Characters built across six dimensions — with a core desire tension, a generated portrait, and a voice they'll use when you interview them. Every detail carries into every chapter.
Build characters through conversation.
Instead of staring at empty form fields, talk through your character with a creative guide — like a writers' room partner who genuinely wants to understand who you're building. It asks open questions about appearance, personality, backstory, desire tensions, and voice. After a few exchanges, it synthesizes a complete character profile that populates every field. Review it, adjust what you want, and make it yours. Available on Pro and Premium plans.
Appearance is just the surface.
Every character has six narrative dimensions — Appearance, Presence, Personality, Sexuality, Backstory, and Speech Style — plus a core desire tension that defines what they want, fear, and resist. Every field can be sparked from scratch or enriched to add depth layer by layer. Desire tensions aren't labels — they're the engine that drives how the character behaves across the arc, from first restraint to final surrender.

Five styles. Three moods. Their face.
Five art styles — Illustration, Sketch, Painterly, Cinematic, Photorealistic — and three moods — Everyday, Intimate, Sensual — generated from the character's appearance. Portraits are always tasteful regardless of character details. Regenerate until you see the person you imagined.
Portraits are always tasteful and non-explicit, regardless of character details.
Ask them anything. They'll stay in character.
Sit down with your character for an ephemeral interview. Their answers are shaped by their profile, backstory, and desire tension. Ask what they're afraid of, who changed them, what they want but won't say out loud. When they reveal something unexpected, merge it back into their profile with one click. The best character details aren't ones you planned — they're ones your characters told you.
Up to four characters. Every chapter.
Select up to four characters for your story and assign each a role — Protagonist, Love Interest, Rival, Confidant, Catalyst, Former Lover. Every character carries their full profile — appearance, desire tension, backstory — into every chapter drafted. The cast isn't a prompt. It's structural context the story can't forget.
The details that make it work
Frequently Asked Questions
Every character is built across six narrative dimensions — Appearance, Presence, Personality, Sexuality, Backstory, and Speech Style — plus a core desire tension that defines what they want, fear, and resist. Each field can be generated from scratch with Spark or deepened layer by layer with Enrich. The result is a character with psychological depth, not just surface-level description.
Desire tensions are core psychological conflicts assigned to each character — like Forbidden Attraction, Trust After Betrayal, or Internalized Shame. They define what a character wants, what holds them back, and the internal war between the two. Desire tensions aren't labels — they're the engine that drives how the character behaves across the arc, from first restraint to final surrender.
The Character Builder is a conversational guide that helps you develop characters through natural dialogue — like a writers' room partner. It asks open questions about appearance, personality, backstory, desire tensions, and voice. After a few exchanges, it synthesizes a complete character profile that populates every field. You review, adjust, and make it yours. Available on Pro and Premium plans.
Character interviews let you sit across from a character and ask them anything — about their fears, desires, memories, whatever you're curious about. The character responds in their own voice, shaped by their profile, backstory, and desire tension. When they reveal something unexpected, you can merge it back into their profile with one click. The best character details are often ones your characters tell you, not ones you planned. Available on Pro and Premium plans.
You can cast up to four characters per story and assign each a role — Protagonist, Love Interest, Rival, Confidant, Catalyst, or Former Lover. Every character carries their full profile into every chapter drafted, so the cast isn't just a prompt — it's structural context the story can't forget.
Yes. Every character's full profile — appearance, desire tension, backstory, and personality — is loaded as context for every chapter generation. There's no context drift, no amnesia, and no contradiction. The character who appears in chapter eight is the same person who appeared in chapter one.
