Why authors choose Inkloom

Four things you get that subscriptions do not give you.

Local-first

Your manuscript lives on your computer. Not on a server.

Bring your own key

Use your own OpenRouter API key. No markup. No middleman.

No subscription

No monthly fee. No recurring billing. No seat charge.

Buy once

$299 one-time. It is yours. 7-day refund if it is not right.

What is included

Five pillars. One system. One price.

Every pillar is included in the $299 purchase. There is no higher tier.

Pillar 1

Build the Book

Concept, Blueprint, Outline, Chapters

Plan the book before you draft it. Concept becomes Blueprint, Blueprint becomes Outline, Outline becomes chapter briefs that every draft must obey.

Pillar 2

Remember the Book

Canon, Continuity, Facts, Open Loops

Inkloom records what your manuscript establishes and warns you when a later chapter contradicts it. Facts, characters, promises, open loops, and key terms become a living memory.

Pillar 3

Protect My Voice

Voice Profile, Project Rules, Voice Pass

Define how you sound. Inkloom finds formulaic and repetitive AI patterns and proposes fixes as reviewable diffs. You decide what changes. Your text is never silently overwritten.

Pillar 4

Finish the Book

Review, Claims, Typography, Cover

Run a whole-book editorial pass. Validate claims. Choose from 110 book typefaces. Preview in print, e-reader, and manuscript formats. Design a cover from your book identity.

Pillar 5

Publish the Book

Print PDF, EPUB, DOCX, KDP-ready files

Export print-ready PDFs in all five KDP trim sizes, reflowable Kindle EPUB, DOCX, and Markdown. A readiness check reports what needs attention before you publish.

Your manuscript lives on your computer. Not ours.

Inkloom runs locally. Your manuscript lives in a local database. The only thing that leaves your machine is what you explicitly send to your own OpenRouter account for generation. A privacy lock can keep your manuscript entirely local even when a key is stored.
