Scribsy — Demo video

Story Sky, by Scribsy: start a novel out loud, and see what's already in it. Story Sky is a voiced Muse that helps a novelist start a story, built by Scribsy on Meta's Muse models. The blank page is where novelists stall. Story Sky turns it into a short spoken conversation. Its Muse asks one easy question aloud, "What's the first thing you see?", and the writer answers in a sentence or two. - Muse Voice Transcribe writes the answer down. - Muse Spark points at the people, places, things and open questions already in it. Every card carries an exact quote that the page checks mechanically: if the quote isn't an exact substring of the transcript, the card is thrown away in plain sight. A name only becomes a person or a place when the writer's own words show it. - Story Sky asks back, up to three times, with published Clean Language questions built only from the writer's words. It never answers or suggests. - The writer keeps the cards that belong to their story. Muse Image paints a night sky with the kept cards as its constellation. The model proposes; the writer's words decide. Built during the hackathon: everything in the repository, started from empty on 31 Oct 2026. - the quote and clue verifier; - the question grammar; - the prompts and JSON schemas; - the API; - a rules-only fallback that runs in the browser; - a hosted version on Cloudflare Workers, behind an access code, with daily spend and per-visitor caps kept in a Durable Object; a phone layout; - 28 tests. No Scribsy app code is included, and nothing in the Scribsy app changes. The spoken voices are ElevenLabs. The story in the video was written for it. Try it: https://story-sky.stevenrpattison.workers.dev Use Chrome. Enter the access code: sky-uzc6-5g74-zjdk Click Begin, allow the microphone and answer out loud. Headphones help. "Play a recorded run" works without the code. If the day's live budget runs out, the page says so and carries on with the rules alone. Next: testing with novelists. A consented, one-time hand-off into a new Scribsy account is already built and switched off - allowing writers to take their work with Muse on Story Sky right into a new account or document with the story bible already started.
