OmniPhraser uses a forensic-grade rewriting engine to transform rough academic text into polished, natural, plagiarism-resilient prose — in seconds.
No setup. No account required for basic use. Just paste and go.
Drop in your notes, draft, or rough paragraph. Up to 1,000 words at once with a Pro plan.
Choose from Standard, Fluent, Formal, Creative, or Expanded — each tailors the style and vocabulary depth.
Our forensic engine rebuilds sentence structure, swaps vocabulary intelligently, and scores your output for AI-bypass.
Standard keeps your meaning tight. Fluent smooths the flow. Formal elevates register. Creative breaks the mould. Expanded adds depth. One text, five angles.
Tap any highlighted word in your output to see all synonym alternatives. Swap instantly. You stay in full editorial control.
Each output is scored live for BLEU-4, METEOR, and burstiness. You see your AI-detection risk in real time before you submit.
Switch dialects in one click. Vocabulary, spelling, and academic register adjust automatically for your target journal or institution.
Your text is processed on our private, secured backend. No data is stored, sold, or shared. What you write stays yours.
The engine pre-warms silently when you open the app, so your Standard result loads first — other modes load on demand.
