Underfiction: AI Roleplay

She opens the letter. The room is quiet. You decide what happens next. Underfiction is interactive storytelling in literary prose. Start from an authored scene or from a sentence of your own. Direct the scene from inside it or outside it; the engine follows. — START IN A SCENE ALREADY SET — Enter Pride and Prejudice, Jane Eyre, Dracula, Persuasion, or Sherlock Holmes at a moment already in motion. Or choose one of four original worlds: a Regency house party, a summer estate, a fantasy tavern, or a deep-space freighter. Each comes with authored scenes to start from: pick one, change anything, and watch the first page arrive. Prefer a blank page? Create any setting, cast, and tone you want. — YOU’RE THE DIRECTOR — Write what your character says or does: • “She opens the letter.” Speak as anyone in the cast: • “Have the captain lie about the fuel.” Or direct the narrator: • “Slow down. Let the silence do the work.” Choose first or second person, present tense, or inner thoughts. Add a standing direction — “keep her unreliable” or “no dialogue tags” — and every turn in that story follows it. — PROSE, NOT CHAT — Every response is written as fiction: scene-setting, interior monologue, tension, rhythm, and subtext. Choose among leading language models and switch mid-scene when you want a different voice. — STORIES THAT REMEMBER — Scenes work like chapters. When one ends, its essential events carry into the next. Long scenes compress older passages automatically, so the story can continue without losing the thread. Summaries and compression are free; you pay only for generated prose. — SEE IT. HEAR IT. — Attach a face, room, or photograph and let the narrator write from what it sees. Generate character portraits and scene art, animate an image, set a backdrop, or have any passage read aloud in the voice you choose. — YOUR LIBRARY, EVERYWHERE — Stories, characters, and worlds follow you to every device you sign in on. Stories are encrypted at rest on our servers, and we don't read them. One switch turns sync off — then your library lives on that device alone. Either way, export a readable story at any turn, carry a complete story with its cast and media, or move your entire library between your devices in one portable Underfiction file. Underfiction also imports Tavern character cards and world books, so you are never locked into one library. — CREDITS, NOT SUBSCRIPTIONS — Start free. When you want more, buy credits for the words and media you generate. Credits do not expire. No recurring plan, no ads, no selling your writing. Open a story. Take the pen.
