CanvasChapters as structure — revisions you can navigate
A novel is hundreds of decisions across months. Canvas treats chapters and scenes as blocks with save points for daily work, draft lines for “what if Act 2 went darker”, and AI skills that propose block-level diffs — not whole-chapter rewrites in a chat window. Markdown round-trips losslessly when you need git or another editor.

On working with constraints
Constraints don't fight a draft — they give it edges. The hardest part of any long document is deciding what it isn't.
Working hypothesis: the more open the canvas, the longer the first paragraph takes.
Outline section 2 · Confirm three quotes · Draft conclusion
const audience = readers.filter(r => r.cares_about(topic))Source · Year · Quoted on page
Headings, scenes, and blocks — not one undifferentiated blob
24+ block types: chapter headings, callouts, tables, citations, research sidebars. Structure-check skills flag when your outline and your draft diverge — before your editor does.
- Heading hierarchy mirrors your act and chapter structure
- Research blocks link to sources beside the draft they inform
- Block-aware diffs show which sections moved or were rewritten
Draft lines for the darker Act 2 you are not sure about yet
Major plot forks should not mean duplicate Scrivener projects or terrifying undo chains. Save point before the rewrite; draft line for the alternate beat sheet; diff against main before you commit the structural change your agent will ask about.
- Save points for daily work and submission milestones
- Draft lines explore alternate arcs without losing the trunk manuscript
- Incorporate the arc that works; keep the other for reference

Markdown round-trip — your manuscript is never trapped
Write for months in Canvas; export standard markdown when you need git, a collaborator on another tool, or a backup you control. Import existing markdown without losing heading structure — the same save-point history applies from day one.
- Lossless markdown export — not a proprietary snapshot format
- Paste in from another editor; structure maps to blocks on import
- Canvas early access for Pro and Team subscribers
Canvas — a novel is hundreds of structural decisions — Canvas keeps each fork diffable before you commit the rewrite your agent will ask about.
What Canvas adds for novelists
The three primitives that do the heavy lifting in this workflow.
Tone and structure passes on blocks
Outline → draft, structure check, and tone pass propose edits at block granularity — you see what changed and accept piecemeal. No whole-chapter regeneration you cannot trust.
Research beside the manuscript
Citation and research blocks live in the document tree next to the chapters they inform — not a separate folder of PDFs you manually reconcile.
Workshop-ready history
Save point before workshop submission; diff after critique for your revision letter — exact structural change, not “I changed a lot.”
Skills and diffs run on your draft — nothing lands until you accept it. Every accepted change can become a save point.
Act-level rewrite without losing the original
The fork every novelist hits — explored safely, merged deliberately.
- Save point
Save point before the rewrite
“Pre–Act 2 rewrite” freezes the manuscript you might need to return to.
- Draft line
Draft line for the alternate arc
Write the darker beat sheet on a parallel line; main stays untouched.
- Compare
Compare before you keep it
Block-level changes show which chapters move, which scenes change voice or plot.
- Incorporate
Incorporate or discard
Pull winning scenes to main; keep the branch if your editor wants to see what you tried.
What buyers ask before they switch
Migration, granularity, pricing, and feature status — the concrete questions buyers raise before they switch.
How does Canvas early access work for novelists?
Canvas is in early access for Pro and Team subscribers — join from the Canvas product page. It shares save points, draft lines, and the AI skill engine with Plot — extended for long-form block documents rather than screenplay element types.
Can I migrate from Scrivener or Word without rebuilding structure?
Import via markdown or structured paste where headings map to blocks. Complex Scrivener binder metadata may need manual cleanup once — after that, chapters and research blocks live in one Canvas document with version history.
How do block-level AI passes avoid rewriting whole chapters blindly?
Skills propose diffs at block granularity — a paragraph, a scene break, a callout — not a full-document replace. You accept or reject each suggestion; the manuscript does not change until you confirm.
If I leave Inkwell, what do I take with me?
Standard markdown export with heading structure preserved. Save-point history is Inkwell-specific — export snapshots you need as markdown files before canceling if you want offline archives of milestones.
