start free. stay for the room. no tricks, no lock-in.
everything you need to draft.
for the book you're finishing
co-writers, custom personas, shared memory.
god no. you're going to write your book. quarkle just refuses to let you quit at chapter three.
it shouldn't, but you stay the judge. every change arrives as a preview you can accept, reject, or rewrite yourself.
hit keep mine. quarkle won't sulk. it genuinely doesn't have feelings. probably.
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.
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.
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.
