Features

Everything you need to write something great.

A professional writing environment for novels, non-fiction, and long-form work — with an AI co-author that reads and remembers your whole book. A complete writing workspace with an AI co-author that reads your whole project, reviews your draft, and helps you ship it.

AI co-author

An AI that understands your whole project

Not autocomplete. A project-scoped collaborator that reads what you've written, keeps context, and works alongside you.

Agentic writing partner

The agent explores your files, drafts and edits in place, then verifies its own work — word counts, continuity, and structure — and self-corrects across a bounded loop.

Full-project context (RAG)

Every save is chunked and embedded. The agent retrieves the most relevant passages from your entire project, so it answers from your manuscript — not a blank slate.

Live Edit on any selection

Highlight a passage to rewrite, fact-check, add a citation, or run a custom prompt — without leaving the editor. Works in Markdown and rich-text modes.

Book-wide jobs

Ask it to revise the outline and every chapter and it runs in the background, rewriting one file at a time while you keep working. Watch live progress and cancel any time.

Format-aware writing modes

Novels, non-fiction, cookbooks, screenplays, zines, websites — the agent adapts its voice, structure, and continuity checks to what you're actually making.

Collaborative direction

At a real creative fork the agent asks one focused question — naming the tradeoff in story, pacing, or tone — instead of guessing. Suggested next-step chips keep momentum.

The workspace

It feels like your IDE — built for prose

A familiar three-pane environment: files on the left, your editor in the middle, the AI on the right. Plus everything you'd expect from a real editor.

Three-pane editor

File tree, tabbed multi-file editing, and an AI panel — with a top menu bar, status bar, command palette (⌘/Ctrl+K), and keyboard shortcuts throughout.

Three ways to write

Monaco Markdown source, a rich-text WYSIWYG, or a distraction-free Document mode. Files are always saved as clean Markdown, so structure is never flattened.

Focus mode & live preview

Go full-screen and distraction-free, or open a read-only preview pane that renders headings, images, and Mermaid diagrams beside your source.

Built for mobile too

On phones the workspace collapses to a single pane with a Files / Editor / Agent tab bar, and the composer stays above the on-screen keyboard.

Light, dark & literary themes

Switch between light, dark, system, and monochrome literary themes — your choice follows you across the landing page and the workspace.

?

Guided from the start

A first-run tour, a searchable in-app help guide, and stale-tab safeguards mean you're never lost — and never silently overwriting your own work.

Projects

Start anything, bring in everything

From a blank novel to an imported manuscript, projects come pre-structured for the kind of writing you do.

Many formats, real scaffolding

Novels, novellas, poetry, screenplays, memoir, research, cookbooks, business plans, journals, websites and more — each gets format-appropriate folders and assist files.

Import your existing work

Bring in .docx, .pdf, and .txt. DOCX images come along, chapters are laid out for you, and the whole thing is indexed and embedded so the AI knows it immediately.

A dashboard that scales

Search, filter, sort, and pin projects; switch between grid and list; and adjust density. Your layout preferences persist in the browser.

AI cover art

Every project can get genre-aware cover art generated on create — or upload your own. Covers show on dashboard cards and in the workspace.

Save project as

Clone a project with all of its files and settings to branch in a new direction, with fresh indexing and embeddings.

Smart onboarding

A short wizard captures what you're writing, then an AI starter pack can seed your world brief, characters, places, timeline, and outline before you type a word.

Craft & analysis

Tools that strengthen the work

Catch problems, see your world clearly, and keep long projects internally consistent.

Inline review

Annotate files with severity-coded issues — minor to critical — each with an explanation, a suggested fix you can apply with one click, and an option to ignore.

Project scan

A whole-project pass that flags missing files, broken links, thin chapters, and continuity drift, with an optional deeper AI consistency check.

Character & timeline maps

An interactive cast list with relationships and AI-generated portraits, plus a chronological timeline view with an optional Gantt overview — all from your assist files.

Citations & references

Chicago, MLA, APA, Turabian, OSCOLA, or Bluebook with footnotes or endnotes, an auto-maintained bibliography, and citation markers on factual claims.

Figures, images & diagrams

Upload or generate illustrations, drop them into chapters, plan figures per chapter, and render Mermaid diagrams right in the preview.

Auto-maintained registries

Canonical timeline, characters, places, and terms files keep your world consistent, and a live project index maps your whole manuscript.

Versioning & export

Keep history, then take it anywhere

Never lose a draft, and turn your project into a polished document in seconds.

Source Control

Commit named, project-wide snapshots with AI-suggested titles, browse what changed, and roll the whole project back to any prior version.

Per-file version history

Every file keeps its own snapshot timeline with inline diffs. Restoring is non-destructive — it just creates a new snapshot.

Export anywhere

Render to .docx, .pdf, .txt, or .rtf — per file or the whole manuscript — with proper formatting, embedded images, and a clean export option.

Save everything at once

Save all open tabs without a commit, or export your entire project as a ZIP that preserves your folder structure.
