How to Choose the Best Paraphrasing Tool
Not all paraphrasing tools are created equal. Here's what to look for:
Accuracy & Meaning Preservation
The tool should restructure sentences while keeping the original meaning intact — not just swap synonyms.
Plagiarism Safety
Output should pass plagiarism checkers by producing genuinely unique phrasing, not detectable patterns.
Speed & Workflow Integration
Look for tools that fit your workflow. Copy-pasting into browsers wastes time — inline tools are faster.
Privacy & Data Handling
Check if your text is stored or used for training. Desktop apps typically offer better privacy than web tools.
Ease of Use
Complex dashboards slow you down. The best tools are simple — select text, trigger rewrite, done.

Frequently Asked Questions
Can AI paraphrasing still be detected?
High-quality AI paraphrasing is difficult to detect because it restructures sentences naturally rather than just swapping synonyms. However, no tool is 100% undetectable — the output quality depends on how you use it and review the results.
Is this suitable for sensitive documents?
We process text securely and discard it immediately — nothing is stored. However, for highly confidential data (legal, medical), always review your organization's policies on using AI tools. See our Privacy Policy.
Does it work offline?
The app runs locally on your desktop, but requires internet to process text with AI. The UI works offline — you just need connection for rewrites.
How is this different from QuillBot?
QuillBot requires copy-pasting into a browser. Rephrazo works inline in any app — Word, Outlook, Slack. No tab switching, instant speed. See comparison.
Is it free?
Yes. Rephrazo has a generous free tier. No credit card required, no hidden limits on daily use.
