the free plan shows you the room. pro turns the lights on. here's what changes the day you upgrade.
four readability passes, four structure passes, four style passes, and four advanced craft passes read the same chapter. an AI consolidation pass gathers their notes, removes duplicates and conflicts, and returns one focused review.
every character, every world, every plot beat, every house rule (never kill the dog), kept in an atlas quarkle updates as you write. ask what color were eldra's eyes? and it looks it up instead of guessing. pro means the atlas never fills up.
quarkle changes a line right where it lives: yours struck through, its proposal in pink. accept in one keystroke. keep yours in another. the before and after stay in eye contact. no tabs, no copy-paste, no context collapse.
100x the usage of the free plan, so you're never counting revisions. pick the best writing model for each scene instead of auto-only. priority support when you need it. export any time (.docx, .pdf, .md, or plain text) and walk out with your manuscript.
studio (for teams) is the only plan above pro, and we only sell it when you ask. try pro for $4.99 the first month, cancel any time, keep every word you wrote either way.
the full room: sixteen specialist AI passes, one consolidation, four export formats.
