dispatch №01 · hello, writer

bad drafts,
goodcompany.

psst,

your novel has been sitting there for months. quarkle is the AI editor built for it: it reads every line, remembers the details, and helps you decide what the next draft needs.(you keep the pen. quarkle keeps the thread.)

ch04 - the ascent.mdquarkle · compression

The dragon was big and scary. It flew through the skycame down from the clouds like an avalanche with wings. Eldra was scared but she kept runningran anyway.

quarkle · margin note
Three flat sentences into two with stakes. The avalanche image does the work of "big and scary", and "ran anyway" is braver than "was scared but kept running."

what quarkle actually is

an AI editor for novelists, memoirists, and self-publishers.

not a chatbot. four tools built around one manuscript, so the book gets finished.

01
the review room

12 specialist AI passes across copy, line, developmental & continuity craft, reconciled into one set of notes.

02
the story atlas

characters, world, and plot: remembered and kept in sync as you write.

03
editorial reports

a verdict, a revision plan, open threads, a tension map, from one read.

04
chat & brainstorm

a writing partner that reads your manuscript before it answers.

the book's brain · feature nº 05

ask it anything. it already knows.

quarkle re-reads your chapters and notes before it answers: characters, world, and plot details it keeps updated as you write. this is the real Quarkle Studio, mid-conversation.

i cried twice. once when quarkle caught a continuity error from 80 pages back. once when it told me my opening was actually good.

the honest part

questions people actually ask.

q.01is quarkle going to write my book for me?+

god no. you're going to write your book. quarkle just refuses to let you quit at chapter three.

q.02will quarkle flatten my voice?+

it shouldn't, but you stay the judge. every change arrives as a preview you can accept, reject, or rewrite yourself.

q.03what if i hate the suggestion?+

hit keep mine. quarkle won't sulk. it genuinely doesn't have feelings. probably.

q.04does quarkle train on my book?+

no. we don't train models on your manuscript, and we don't sell it. approved providers process only what a feature needs to run, and you can export your book anytime.

q.05what does pro actually add?+

open expression for mature scenes, every model in chat instead of just auto, the deeper developmental and full assessment reports, and 200x the daily usage. the review room, inline edits, and version history are already free.

q.06what can i import and export?+

import PDF, Markdown, or plain text. export Word, PDF, Markdown, or plain text, chapter by chapter or as one document. for Scrivener, export a compile as PDF or plain text and import that.

q.07what does 'quarkle' even mean?+

honestly, we made it up. it sounded like a good name for an alien pal, the kind of friend you'd let read your draft before your mother does. the dictionary will catch up.

a letter, to you · from us

press the seal.
start the book.

dear writer,

the book is already inside you. we will not write it for you. we will sit beside you while you do. we will remember every page. we will not flinch at a first draft. we will be here tomorrow and the tomorrow after that.

    yours, quarkle
