Most users rewrite first, then run a last detection check to catch sections that still feel too uniform before the draft goes out.

It helps me turn rough AI-assisted drafts into something I would actually submit.
I use Lumi to smooth repetition, tighten sentence flow, and make sure the final draft sounds like me before I hand anything in.

Our first drafts sound less generic and need fewer manual edits.
We use Lumi to reshape outlines and AI-assisted copy into publishable posts with clearer tone, structure, and pacing.

The rewrite and grammar workflow gives me a cleaner version without losing the original point, which saves a lot of revision time.
