sees the whole shape of your book at once.
we didn’t ship a feature. we shipped a partner.
for most of quarkle’s life, the assistant answered once, guessed well, and moved on. that was fine for a note. it was never enough for a novel.
so we tore out the single-shot brain and wrote a new one. quarkle iii is an agent — a patient reader that picks up your book, pulls the files it needs, checks the web when it should, keeps re-reading until the ask is answered, and only then tells you what it found. it remembers more. it refuses less. it guesses rarely.
this note is the short version. the long version is below — a tour of the new brain, the new memory, the new tools, and a handful of small kindnesses we snuck in while we were down there.
not a chatbot.
an agent that stays on the question.
every message now runs through a real loop. quarkle classifies the ask, fetches the evidence it actually needs, re-reads your chapters, searches your knowledge base, looks up the web when it should — and keeps going until the question is genuinely answered.
twelve tools on the desk. quietly capable.
quarkle iii doesn’t just talk. it reads your chapters, searches your notes, looks up facts, annotates pages, and updates its own memory — on its own, in one conversation, until your ask is done.
pulls a chapter, or a range of lines, into working memory.
semantic search across every word you’ve written.
a literal find for when you know the exact phrase.
a map of everything you’ve taught it — characters, worlds, lore.
opens any knowledge file by name, like flipping to a page.
finds the right note even when you don’t remember the title.
writes a new note — and re-indexes the whole atlas.
rewrites a note cleanly, not by clumsy append.
looks up a real fact on the real internet, with sources.
finds what you two already discussed, across every session.
leaves margin notes on a chapter — a true reader’s pass.
an atlas of your world.
the knowledge base used to be characters. in iii, it’s anything — worlds, technology, magic systems, lore, subplots, rules, timelines, running jokes. add a folder. drop in a file. your writing partner picks it up.
- infinite foldersorganize by book, by world, by series, by how your brain actually works.
- auto-indexedevery save rebuilds the map. the agent always knows what’s in there.
- re-read on changeedit a chapter; its summary re-reads itself in the background.
- yours, portableplain markdown files. if you leave, you leave with them.
edits that land on the right line.
suggestions in iii are tied to precise line numbers, stream in as the agent thinks, and show up where they belong — not in a side panel, not in a copy-paste dialog. your line, struck through. its line, in pink. one keystroke each way.
- suggestions only when you’re actually editing — chat asks get chat answers
- multiple suggestions per reply, each anchored to its own lines
- accept and keep-mine are one keystroke, not a modal
- the agent explains why, not just what — in one short sentence
and a handful of tiny, considered things.
while we were rewriting the brain, we also cleaned the desk.
- +suggestion tags are smarter. quarkle only emits inline-edit format when you’re actually editing — chat asks come back as plain prose.
- +prompt caching is on. the second turn in a conversation is noticeably faster — and noticeably cheaper to serve, which is how we keep the free tier generous.
- +it never forgets across sessions. ask it what you two discussed last tuesday; it finds the exchange and reads it back.
- +safety without gatekeeping. fiction is allowed to be dark. iii refuses only what genuinely shouldn’t be written — and for pro writers, a true open-expression model is one click away.
- +background refresh. edit a chapter and walk away — its summary updates on its own, so the next conversation starts with the new version already in mind.
- +every turn is inspectable. curious what tools it used? which model answered? how long it thought? every reply keeps the receipts.
- +thirteen-plus models, one door. claude, gpt, gemini, kimi, deepseek — quarkle picks for the task, and fails over automatically if a provider stumbles.
- +exports, full-fat. .docx, .pdf, .epub, .md, .txt — chapter-by-chapter or bound together, yours to take anywhere.
pro turns the lights on.
iii is generous on the free tier. but if you’re finishing a novel, you want the sixteen-editor room, the open-expression model, the deeper reasoning tier, and the knowledge base without a ceiling.
- the 16-editor room · senior editor passes
- thirteen-plus models · open-expression for fiction
- deep-reasoning tier on every hard ask
- knowledge base without a ceiling · characters, worlds, lore
- every export format · your words never train a model
