AI roleplay & story-writing, without the technical mess.
Autonym is a structured, compendium-first desktop app for solo roleplayers and authors. Build a Cast from labeled fields instead of prompt engineering, pace scenes with Beat Sheets and Mood presets, and let dynamic Lorebooks keep your world consistent — all running on your own OpenRouter key.
Instead of forcing you to master raw prompt engineering, Autonym paces scenes through interactive Beat Sheets and a one-click Mood & Pacing selector, injects lore automatically through cue-word Lorebooks, and shows transparent per-message pricing with prompt caching on supported models.
Everything a long-form roleplay needs, none of the busywork.
Eight systems that work together — from a first character sheet to a finished, exported story.
Beat Sheets & Mood presets
A drag-and-drop scene roadmap plus one-click steering — Slow Burn, High Action & Grit, Cinematic & Atmospheric, Slice of Life — that resists the model's urge to resolve tension too fast.
Dynamic Lorebooks
Cue-word-triggered world-info injection, with an AI-assisted "Fill from Wiki/Text" importer that recognizes Fandom wiki markup for one-paste entries.
Universes & linked variants
Group your Cast by world or verse, then link a canon or AU take on a character to a base version that shares personality automatically — no duplicate sheets.
Skits
Unattended short-story generation — pick a premise and a length, and the AI writes a complete short scene end to end. Ideal for ship fic without the typing.
Curated, RP-tuned models
Built-in presets for current-gen Claude, Magnum, and Euryale, filtered against OpenRouter's live catalog so dead or unsuitable models never waste your time — with transparent per-message cost estimates.
Prompt caching
Automatic prompt caching on supported Claude models keeps lore-heavy, long-running scenes fast and cheap.
Direct export
Export a single Act or a whole combined Storyline straight to EPUB, PDF, or Markdown — for reading elsewhere or keeping an archive.
Fully local, privacy-first
Your data stays on your machine. Your OpenRouter key is encrypted at rest with OS-level encryption and never leaves the main process in plaintext.
From a blank Cast to a finished scene.
Build your Cast
Fill in labeled fields — appearance, personality, speech style, background — or paste a wiki page and let Autonym structure it for you.
Set the scene
Pick a Universe, attach a Lorebook, choose a Mood & Pacing preset and a Content Intensity level, and start an Act.
Write, or let it write
Reply turn by turn, co-write in Collaborative Mode, or hand it off entirely to a Skit and get a finished short scene back.
Your key, your machine, your story.
Encrypted key storage
Your OpenRouter API key is encrypted at rest via OS-level credential encryption and is only ever used from Electron's main process.
No account, no telemetry
There's no Autonym account and nothing phones home. You talk to OpenRouter directly, on the model of your choice, at the price it quotes.
