Reviewers are grouped into tiers.
Many editors, in tiers
Each reviewer you have switched on is its own editor with its own brief. They’re organised into tiers, one per editing job. Copy → Line → Developmental → Continuity → your Custom reviewers Within a tier, the editors are junior editors, and they read the chapter in parallel. The grammar editor, the clarity editor, and the redundancy editor all read at the same time, each returning specific, structured notes: a line, a problem, a suggested rewrite, and the reasoning.The senior editor pass
Multiple editors often flag the same sentence. Quarkle handles this the way a real editorial team does, with a senior editor for each tier. After the junior editors finish, the senior editor reads their notes together, merges duplicates, drops the weak ones, and keeps the sharpest version of each point. That’s what actually reaches your margin.Why comments arrive in waves
The chapter is split into manageable chunks and the tiers are released in order, so comments stream in as each tier completes rather than all at once. Higher tiers wait for the lower ones. Any line that’s already been commented on is skipped, so a Line note won’t pile onto a sentence a Copy editor already flagged. You can stop the whole thing at any point.Where custom reviewers fit
Your custom reviewers run as their own tier, right alongside the built-in ones, using the instructions and examples you gave them. They go through the same junior-then-senior flow, so your bespoke editor’s notes are held to the same non-repetitive standard.Pro gets more room to think
On Pro, the Review Room gives each chunk more time and reaches for stronger models. That generally means deeper, more considered notes on longer or more complex chapters.The everyday how-to lives in The Review Room. Custom reviewers covers building your own editor.
