Three AI agents

The Keeper, the Scribe, and the Editor

Each is a specialist. Together, they are a workshop.

Lore Keeper

The Keeper

Remembers every detail of your world, characters, and rules — keeping continuity across chapters.

Scribe

The Scribe

Drafts chapter by chapter from your story plan — in the style and direction you choose.

Editor

The Editor

Reviews each chapter with a piercing eye — scores it and points out what to refine.

Workshop tools

Everything you need, every step of the way

From outline to delivery, all in one place.

Story Plan

Outline the narrative, break it into acts and beats, with status and ordering.

World KB

Build entities for characters, places, factions, and artifacts — with relationships.

Arcane Dock

Chat with any agent via a slide-in dock on every page — never lose context.

Ingest

Import .docx / .pdf — let AI extract characters and lore automatically.

Export

Export to Markdown, PDF, or eBook — per chapter or compiled as a tome.

Chat

Talk to WRITER in real time — ask to continue, expand, or summarize.

Schedules

Set a cron schedule for autonomous writing — hourly, daily, or weekly.

Critic Rubric

A 5-dimension rubric — lore, character voice, plot, prose, continuity.

Autonomous pipeline

One click. A new chapter.

LORE preps → WRITER drafts → CRITIC scores → if it passes, the chapter is saved.

01

LORE prep

Reviews the last chapter, builds writer guidelines, summarizes the story so far.

02

WRITER drafts

Drafts a new chapter from the plan, using tools to search the world.

03

CRITIC reviews

Scores 0–10 across 5 dimensions. Must hit 7+ to pass.

Scheduled runs

Cron-based scheduler — write every hour, day, or week.

Loop until it passes

If CRITIC rejects, WRITER rewrites based on the feedback, up to 3 times.

Time-bounded

Hard 35-minute ceiling — no run ever pins your machine overnight.
