About this tool

The ShishwaLab AI Paraphraser is a free paraphrasing tool and sentence rewriter that uses a controlled bundled thesaurus plus deterministic sentence restructuring. It never applies uncontrolled random synonym replacement, so meaning stays steadier than roulette-style rewriters.

Five modes cover common rewrite goals: Fluency for smoother wording, Professional for workplace clarity, Academic for formal papers, Simple for easier reading, and Creative for fresher voice. Technical terms, names, dates, numbers, URLs, citations, and quotes are preserved where practical.

You see original and output word counts, how many words changed, a readability comparison, and highlighted changes. Processing runs locally in your browser. This tool does not promise plagiarism evasion, Turnitin bypass, or academic-integrity shortcuts—treat output as a draft you still review.

Tips for better results

  • Start with Fluency for everyday rewrites; switch to Academic or Professional when tone matters more than casual smoothness.
  • Read the highlighted changes and changed-word count before you copy—spot any term that should stay exact.
  • Use Replace input with output to iterate mode-by-mode without re-pasting.
  • Do not treat paraphrasing as plagiarism evasion. Cite sources and keep your own ideas intact.

Mode guide

Rewrite with intent, not random synonyms

Each mode steers the controlled thesaurus and deterministic restructuring toward a different outcome. Protected tokens (URLs, numbers, citations, quotes, technical terms) stay intact where practical. This is a paraphrasing helper—not a plagiarism-evasion tool.

Fluency

Best default for everyday drafts. Prefers natural synonyms and light clause cleanup so sentences read more smoothly.

Professional

Best for emails, reports, and workplace updates. Favors direct wording and clear structure over casual phrasing.

Academic

Best for essays and formal explanations. Expands contractions, keeps a measured register, and stays citation-friendly.

Simple

Best when dense wording gets in the way. Swaps harder words for clearer ones and shortens long sentences where safe.

Creative

Best for marketing blurbs and storytelling. Chooses livelier verbs and fresher phrasing without inventing new facts.
