Boilerplate

Short — about 50 words

Underfiction puts stories, roleplay, and chat with frontier models in one app, built on three primitives: stories, characters, worlds. Scene illustration, image-to-video, and sync across web, iOS, and Android. No content filter, no subscription, no ads — pay-per-word credits, real model names, and prose that reads like a book.

Standard — about 120 words

Underfiction is stories, roleplay, and chat-style scenes in one app — not one or the other. Everything is built from three primitives: stories, characters, and worlds; no config files, no jailbreaks. Readers write with the widest model choice in the category — frontier models beside uncensored open-weights, switchable on any turn, newest models the day they release — and the picker shows real model names, not pet-named finetunes. Scenes can be illustrated, images animated to video, and everything syncs across web and the native iOS and Android apps, encrypted at rest and never read or trained on. There is no content filter, no subscription, no ads, and no engagement bait: credits are spent per generated word and never expire. Localized in eight languages.

What makes it different

• Everything in one app: stories, roleplay, and chat-style scenes — plus scene illustration, image-to-video, and sync. Not a chat app or a story app; both, done properly.
• Three simple primitives — stories, characters, worlds. No config files, no jailbreaks, no prompt engineering.
• Max model choice, less censored: frontier models beside uncensored open-weights, switchable mid-story on any turn.
• Real model names. Competitors hide their engines behind pet-named finetunes and tiers; here the picker says what's actually writing, and a retired model keeps its real name in the story's history.
• Respect as a feature: no subscription, no ads, no engagement bait, no streaks. Credits are spent per generated word and never expire.
• Style, taste, focus: native apps with a reading app's quiet, prose set like a book page, and copy that sells stories rather than "AI".
