1. QuillBot — Best Overall
QuillBot remains the most popular AI paraphrasing tool for good reason.

The free plan is generous — up to 125 words per paraphrase — and the premium plan removes all limits.
- Best modes for bloggers: Fluency (natural reading), Creative (variety), Simple (accessibility)
- Also includes: Summarizer, grammar checker, citation generator, co-writer
- Price: Free (125 words/use), Premium $9.95/mo or $49.95/yr
2. Wordtune — Best for Sentence-Level Rewriting
Wordtune focuses on making individual sentences better rather than paraphrasing large blocks. It suggests alternative phrasings in real time as you write, making it excellent for editing rather than bulk rewriting. The “Spices” feature adds supporting facts, examples, and counterarguments to your writing.
- Unique feature: Real-time inline suggestions as you type
- Price: Free (10 rewrites/day), Plus $13.99/mo
3. Grammarly Rewrite Features
Grammarly’s premium plan now includes rewriting suggestions that go beyond grammar fixes. The “Improve It” button can rewrite selected text for clarity, conciseness, or tone. For bloggers already using Grammarly, this is often the most convenient option since it’s already integrated into your workflow.
4. Undetectable.ai — Best for Humanizing AI Content
If you need to rewrite AI-generated content to sound more human (and pass AI detectors), Undetectable.ai is purpose-built for this. It analyzes your content’s AI signals and rewrites it to score higher on human-likeness metrics.
- Price: From $9.99/mo (10,000 words)
Tips for Using Paraphrasing Tools Effectively
- Always paraphrase in short sections (1-3 paragraphs) for better quality
- Use multiple modes and pick the best output, not just the first suggestion
- Read the output aloud — paraphrasing tools sometimes produce technically correct but awkward text
- Don’t use paraphrasing to disguise plagiarism — always add your own voice and value
Final Verdict
QuillBot is the best all-around paraphrasing tool for bloggers, combining power with an excellent free plan. Wordtune is the better choice if you prefer inline suggestions as you write. For humanizing AI content specifically, Undetectable.ai is currently the most effective option. Try QuillBot free here.
