DevLune product · AI writing tool

Three passes, so the rewrite never sees the original.

Humanize rewrites AI-generated text into prose a person would write: a three-stage LLM pipeline that first reduces the input to notes, drafts from those notes in a chosen tone, then polishes token-by-token over a stream. No accounts, no login.

The brief

AI text is recognisable by its phrasing, and a single-pass rewrite keeps that phrasing because the model is looking at it. The fix is structural: make the rewriter work from notes, so the original wording never reaches it.
