Every piece of copy moves through the same pipeline: analyzed against your voice, optimized line by line, and, when you want it, co-written by an AI trained on your best work.
Clarity, voice match, persuasion, economy. Each dimension is scored against a benchmark built from your own top-performing copy, not a one-size-fits-all readability formula.
Paste a draft, connect a doc, or write natively. Scores update as you type.
Not a wall of underlines. DeftCopy proposes the three edits most likely to move the metric you care about (opens, replies, conversions) and shows its reasoning for each.
Accept with one keystroke. Reject and it learns what you'd never say.
The voice model trains on your approved work and your style guide. Ask for a first draft, five subject lines, or a tighter close. Everything arrives sounding like you on a good day.
Nothing ships without a human accept. Full provenance on every AI-touched line.
