Frequently Asked Questions

How does the AI Paraphrasing Tool work?

It splits your text into sentences, analyzes each word, and replaces words with context-appropriate synonyms. Sentence structure is also adjusted for natural flow. Everything runs in your browser.

Is my text sent to any server?

No. All processing happens entirely in your browser using a built-in thesaurus. Your text is never uploaded, stored, or transmitted.

What rewrite modes are available?

Five modes: Standard (balanced), Fluent (natural flow), Formal (academic vocabulary), Creative (alternative phrasings), and Aggressive (sentence reordering and restructuring).

Does it have text-to-speech?

Yes. The tool includes a built-in text-to-speech reader. Listen to the original or rewritten text read aloud, with voice and rate controls.

Can I see vocabulary stats?

Yes. After rewriting, the vocabulary dashboard shows type-token ratio, unique word count, average word length, and average sentence length.

Does it check grammar?

Yes. The tool flags passive voice constructions, wordy phrases, and missing transition words, helping you improve your writing style.

Can I set custom replacement rules?

Yes. Add words that should always be replaced with a specific synonym, or add words that should never be changed.

What is the maximum text length?

You can paraphrase up to 2,000 words per session. There are no daily limits and no sign-up required.
