Umbral InkFeatures
Everything you need to write your next novel, screenplay, or non-fiction book.
Desktop features
Included with $39 perpetual license — Windows, Mac, and Linux
Write offline
Everything works without internet — editing, grammar, spellcheck, complexity flags. Write on airplanes, in coffee shops, at the cabin.
Multi-pane editing
See your whole story at once. Outline, draft, and notes — side by side. No window juggling, no context loss.
Character tags
Tag character names with @Name syntax. Names are excluded from spellcheck and searchable across all panes.
ePub export
Export your manuscript as a properly formatted ePub. Includes table of contents, metadata, and scene breaks.
Cloud features
Optional — from $2/month ($24/year, $9/quarter, or $4/month)
Sync to your GitHub
Your repository, your data. Umbral Ink pushes full version history directly to GitHub — trusted by Fortune 500 companies and government agencies. We never see your writing.
Umbral Ink Cloud
Simpler setup if you prefer. Encrypted sync across devices with automatic backup. Your manuscript stored as readable markdown.
Web companion
Edit your synced projects from any browser. Perfect for quick edits away from your main computer.
Version snapshots
Save named snapshots of your work. Browse history, compare versions, and restore any previous state.
Collaboration
Coming soon — optional Premium feature
Margin notes
Add feedback in a dedicated pane — like writing in the margins. Leave comments on sections, get responses, iterate. Works with human collaborators or AI.
Privacy-first AI
When you use AI feedback, it's configured with no-store, no-train policies. Your content is processed and forgotten — no one sees it but you.
Built for the craft, not the data — by a writer who uses it daily.
Your writing stays yours.
✓ No content storage — Manuscripts stay on your device or your GitHub
✓ No AI training — Your writing is never used to train models
✓ Minimal data collection — Only what's needed for service
