AI Rewriter — Paragraph & Sentence Level Rewriting

Dual-Level Rewriting
Most rewriters work at a single level — they either swap words or shuffle sentences. SupWriter operates at two distinct levels, giving you control over the depth of transformation. Use paragraph-level rewriting for complete structural changes, or sentence-level for targeted precision edits.
Paragraph Rewriter
Paragraph-level rewriting transforms how your ideas are organized and presented. It restructures the logical flow, varies sentence lengths within the paragraph, and adjusts emphasis to create natural reading rhythm. The result reads like a completely different writer composed the same ideas.
Sentence Rewriter
Sentence-level rewriting is precision work. It takes individual sentences and transforms their structure while preserving exact meaning. Perfect for fixing specific sentences that sound robotic or for fine-tuning text that's almost right but needs a human touch.
When to Use Which Level
Choose paragraph rewriting when your content feels structurally artificial — ideas are in the right order but the flow is off. Choose sentence rewriting when specific sentences stand out as AI-generated. Use combined mode when you need a complete transformation for AI detection bypass.
