Every page is designed to work with the others — open one and see the whole picture.
A writing team that keeps going while you sleep — planning your world, drafting the next chapter, and holding it to a standard before it is kept.
Each is a specialist. Together, they are a workshop.
Remembers every detail of your world, characters, and rules — keeping continuity across chapters.
Drafts chapter by chapter from your story plan — in the style and direction you choose.
Reviews each chapter with a piercing eye — scores it and points out what to refine.
From outline to delivery, all in one place.
Outline the narrative, break it into acts and beats, with status and ordering.
Build entities for characters, places, factions, and artifacts — with relationships between them.
Chat with any agent via a slide-in dock on every page — never lose context.
Import .docx / .pdf — let AI extract characters and lore into your world automatically.
Export to Markdown, PDF, or eBook — per chapter or compiled as a tome.
Talk to the Co-Writer in real time — ask to continue, expand, or summarize.
Set a cron schedule for autonomous writing — hourly, daily, or weekly.
A 5-dimension rubric — lore, character voice, plot, prose, continuity.
World-Builder preps → Co-Writer drafts → Editor scores → if it passes, the chapter is saved.
Reviews the last chapter, builds writer guidelines, summarizes the story so far.
Drafts a new chapter from the plan, using tools to search the world and previous chapters.
Scores 0–10 across 5 dimensions. Must hit 7+ to pass.
Cron-based scheduler — write every hour, every day, or every week.
If the Editor rejects it, the Co-Writer rewrites from the notes, up to 3 times.
Hard 35-minute ceiling — no run ever pins your machine overnight.

Nexus gives you instant access to top AI models without juggling API keys.
Magic Library works with any OpenAI-compatible API key you already have. Nexus is the easy path: buy a credit bundle once and every agent in the app draws from the same pool — no accounts, no per-model billing.
Your own API key still works — Nexus is the frictionless path, not the only one.
Free download. Bring your own API key — or buy credits on Nexus for instant access to top models.
Windows will show “Windows protected your PC” the first time you run the installer. Choose More info → Run anyway. This appears because the installer is not yet code-signed, not because anything is wrong with the download.
