Research
Research without leaving the page
A question arrives mid-sentence — a date, a caliber, how long a body keeps a bruise. Ask the companion in the margin and it searches the web, reads what it finds, and answers with sources you can open. You never break the spell of the draft, and it never hands you a sentence to paste — only the facts, so the writing stays yours.
Grounded, and cited
Answers you can check, not just trust
The companion doesn't guess from memory. When a question needs the world outside your book, it runs a web search, reads the results, and comes back with a short answer and the sources behind it — links you can open and judge for yourself. A fact worth putting in a novel is a fact worth checking.
And because it lives in the margin beside your prose, the answer lands where the question came up — no new tab, no second app, no losing the thread of the paragraph you were in the middle of.
In one place
It reads your book and the world
The same companion that holds your canon and quotes your real chapters can also reach outward. Ask it what you established about the locket and it reads your manuscript; ask it what year the telephone reached rural France and it reads the web. One conversation, grounded in both your story and the facts around it.
Research spends credits like any other AI action, and — like everything the companion does — it's optional. The editor is free and complete without it; research is there for the moment you actually need it.

Distraction-free editing
Real book typography, warm paper themes, dark mode, focus mode, and typewriter scroll — a surface built to disappear so the page is the only thing you see.
Revise
Craft lenses
Ten colour washes that reveal your own habits on the page — adverbs, filter words, sentence rhythm, sensory balance, echoes and more — each teaching from both sides so you decide. It recolours your prose; it never rewrites it.
Feel
Ambience
An opt-in, reactive backdrop for the page — a constellation that grows as you finish sentences, an aurora that deepens as you write. Subtle, peripheral, and off unless you want it.
Reflect
Writing stats
Your habit and your book, given back as a calm stats page — a year heatmap, a forgiving streak, your writing persona, the cast of your story, and a shareable Writing Wrapped. It never shames a slow week.
Remember
The Map & structure
The canon of your world — characters, places, facts, every mention — and the outline of your manuscript: parts, chapters, synopses, statuses, reordering.
Think
Marginalia & the AI companion
Notes, to-dos, and chat pinned to the paragraph they're about — beside an AI that reads your whole book, checks it against your canon, and never writes a line of it.
Connect
The MCP connector
Point Claude, ChatGPT, or Cursor at your real book — with a public catalog of editor, critique, character, and craft-drill skills. It reads everything; it never writes your prose.
Automate
The Writer API
Your book as data you can script against — import a legacy manuscript, run a transform, wire a publish pipeline. The one surface where your own prose can flow in and out.
Facts, never prose
It looks things up. You write the line.
Research hands you what's true — a date, a detail, a source — and then stops. It won't draft the sentence that uses it, won't "write this scene with the facts," won't touch the prose. The one hard line holds here too: the words on the page stay yours.
