Developmental editing software

Your book,
read the way
you meant it.

Giluma is developmental editing software for fiction writers — and narrative non-fiction. It reads your whole manuscript, tracks characters and structure across every chapter, and builds a model of your book that gets smarter every session.

No credit card required Your manuscript stays yours Never used for training

Three ways to bring your manuscript in

Manuscript Mode
You have a draft
Upload one or two chapters to start. Giluma builds its understanding of the book as you go — moving backward and forward through the manuscript simultaneously.
Chapter by Chapter
You're mid-draft
Upload chapters as you complete them. Giluma tracks context progressively — confidence levels adjust to what's available, open questions are carried forward.
Studio Mode
You're starting from zero
A structured intake conversation builds your book's architecture — characters, plot, timeline — before chapter one is written. Giluma is present from the first sentence.
How it works

Seven layers of analysis.
One living model of your book.

Whether you're uploading a finished draft, working chapter by chapter, or writing from the first sentence inside Giluma — the same seven-layer analysis engine runs underneath.

Context Assembly

Before Giluma reads a single word of your chapter, it assembles all supporting notes as context — plot, characters, timeline, style. Feedback is never based on the chapter in isolation. Always on the whole book.

Plot note Character notes Timeline Style note

Feedback Loop

Every editorial note you respond to — agree, disagree, or provide more context — trains Giluma's model of your book. Responses are stored and carried forward. The feedback gets sharper the more you use it.

Agree Disagree Context

Six Focus Areas

Analysis runs across six independently controllable focus areas. Turn them on or off per note. Concentrate Giluma's attention exactly where your manuscript needs it.

Character Plot Pacing Style

Voice Protection

Giluma analyses against your intentions, not a universal standard. Departures from convention are flagged for review — not automatically treated as errors. What makes your writing distinctive is protected.

Intentional Flag for review Stored decision

Chapter Intent

Every chapter note in Giluma holds an intent statement — what the reader should feel or understand by the end. Analysis is evaluated against that stated goal. No assumption is made about what the chapter is trying to do.

Stated intent Analysis match

Personal Book Model

Every session, every response, every decision you make inside Giluma is stored in a model specific to your book. It is not a shared knowledge base. It is not trained on other writers. It belongs to your manuscript alone.

Studio Mode

For writers who haven't started yet. A structured intake conversation builds your book's architecture before you write chapter one — characters, dramatic question, act structure, voice register. Giluma is present from the first sentence.

Note types

Seven types of note.
One connected system.

Every note type in Giluma talks to every other. A character note shapes how a chapter note is evaluated. A plot note constrains what a timeline note can contain. The book is a single connected object.

Character
Arc, motivation, voice profile, established traits and deliberate contradictions.
Feeds into — Chapter, Plot, Style
Plot
Dramatic question, act structure, causal chain, open promises and unresolved threads.
Feeds into — Chapter, Timeline, Character
Chapter
The primary writing space. Holds chapter intent, the prose, and the editorial note stream.
References — All other note types
Timeline
Event sequence, date/scene anchors, chronological gaps and narrative time vs story time.
Feeds into — Chapter, Plot
Style
Register, sentence rhythm, narrative distance, prose-level intentions and deliberate departures.
Feeds into — Chapter, Voice protection
Worldbuilding
Rules, geography, systems, constraints. Prevents contradictions across a long or complex manuscript.
Feeds into — Chapter, Character, Plot
Research
Factual anchors for historical fiction or narrative non-fiction. Linked to the chapters that depend on them.
Feeds into — Chapter, Timeline
Why writers need this

You know something is wrong.
You just can't see what.

"Something isn't working."
The most common thing writers feel at the end of a draft. The structure feels off. A character isn't behaving right. The second act loses momentum. But when you're this close to your own work, it's almost impossible to see exactly why.
0
Existing tools that understand the whole book, learn your intentions, and get smarter over time. Until now.
1

Most tools read one chapter at a time

They have no memory of what came before. They cannot see a promise made in Chapter 3 that goes unresolved by Chapter 14. Giluma reads the whole book before it touches any part.

2

Generic feedback treats every voice the same

Most tools flag departures from convention — but your departures might be exactly what makes your writing distinctive. Giluma evaluates against your intentions, not a universal standard.

3

Nothing remembers your decisions

Every session starts from zero. You re-explain the book. The feedback contradicts what it said last time. Nothing compounds. Giluma builds a model of your book that grows with every session.

Giluma is built differently

Whole-book context assembly. Voice protection. A personal book model built from your responses — session by session, decision by decision. It gets smarter the longer you use it.

Our philosophy

Giluma is not a writing assistant.
It is an editorial intelligence.

The difference matters. It does not generate prose. It does not suggest sentences. It observes, questions, and remembers — the way a developmental editor does.

!
What Giluma is not

Giluma will not rewrite your sentences. It will not suggest "better" phrasing, generate alternative text, or offer style improvements as prose. It will not complete your scenes or fill in what you've left blank. These are your decisions, and Giluma has no business making them.

✓
What Giluma does

Giluma observes what is already written. It notices when a character departs from their established voice. It catches unresolved structural promises. It tracks what the reader knows and when. It asks questions. It remembers your answers. It gets smarter. Your manuscript stays yours.
