The Manuscript Operating System

From first thread to finished manuscript.

Your book is bigger than a prompt. Inkloom helps you plan it, write it, remember it, challenge it, polish it, typeset it, cover it, and prepare it for publication while keeping you in control of every decision.

The difference

Your book remembers.

Most AI tools have conversations. Inkloom gives your book a memory.

For fiction

Inkloom remembers what your characters know.

Knowledge states, motivations, relationships, world rules, timeline events, reveals, and open threads. Before drafting a chapter, Inkloom knows what each character wants, knows, and does not know.

For nonfiction

Inkloom remembers what you have already taught.

Thesis, reader promises, key terms, claims and their sources, concepts already explained, and ideas still needing explanation. No concept is used before its introduction chapter.

For training

Inkloom remembers what the learner is ready to learn next.

Prerequisites, skill progression, exercises, checkpoints, assessments, and what the reader can do after each chapter. Chapter 6 will not depend on something never taught in chapters 1 through 5.

For every project

Inkloom remembers what you decided.

Blueprint fields you locked. Canonical facts your book established. Promises you made to the reader. Open loops you have not yet closed. Voice rules you set. Everything is binding on future generation.

Give your manuscript a memory.

See how Inkloom maintains continuity across an entire manuscript, from first chapter to last.

Five pillars

Everything your book needs, in one system.

Inkloom organizes the entire book creation process into five pillars. Each one is always visible on your Dashboard.

AI provenance

Know what your AI knew.

Every AI-made version in a chapter's History carries a Trace button. One click shows exactly what Inkloom knew when it created that version.

  • The model that was used
  • The prompt template and its version
  • The timestamp
  • Every context item: whether it was always included or retrieved by relevance

Continuity

The book remembers what it established.

After you approve a chapter, Inkloom extracts structured facts with confidence scores and source passages. Conflicts become cards. Nothing is ever silently resolved.

  • Facts have statuses: proposed, canonical, superseded, conflicting
  • Conflict detection runs two passes: deterministic and semantic
  • You pick the canonical version or mark the difference as intentional
  • Open loops, key terms, promises, pain points, characters, and world rules tracked in one hub
Authorial control

Inkloom proposes. You decide.

AI is a tool inside the workshop, not the author.

Side-by-side diffs

Every AI proposal arrives as a diff with Accept and Reject. Your text is never overwritten.

Append-only versions

Every edit creates a new version. Restoring creates a new version. Nothing is ever lost.

Full editor without AI

The editor stands alone. Full rich text, manual control of every brief, rule, and outline node. AI is never a requirement.

Inkloom proposes. You decide.

Every AI change arrives as a reviewable diff. Your text is never overwritten. You remain the author.

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.
