Three-pass copyediting built on Chicago Manual of Style rules. Detects your style first, then edits — and delivers tracked-changes .docx files you open straight in Word.
Most copyeditors work in a single pass. Kellen works in three — catching inconsistencies the first pass always misses.
Kellen applies CMOS rules as its foundation, layered on top of your manuscript's own established style.
Credits are $1 each. The style sheet pass is always free — you only pay when you confirm the style sheet and the edit begins.
Word count is rounded up to the nearest 1,000, minimum 1 credit. Pro value based on EFA 2023 median copyediting rate of $0.024/word. Maximum manuscript size: 200,000 words. Credits are automatically refunded if a run fails before completing.
Upload your manuscript, confirm your style sheet, and get tracked-changes back in minutes.
