10 Best AI Sentence Rewriters In 2025 [Reviewed]

Are you looking for the best AI-powered sentence rewriters to save time from manually rewriting your sentences?

I understand some of you will look for a simple sentence rewriter for a one-off task, while others will look for a more advanced and comprehensive one (e.g., handle marketing operations).

In this article, I’ll go over the 10 best AI-powered sentence rewriters in 2025, going over both free-to-use and advanced rewriters for different use cases.

What are the factors to consider when evaluating AI sentence rewriters?

Without spending too much time on this section, here are the 3 key factors I’d consider in an AI sentence rewriter:

#1: Similarity to the original sentence

The reason why you are looking for a sentence generator is that you want to re-spin your existing content, or you want to rewrite your competitors’ content.

This is why the similarity to the original sentence (without losing its meaning) was the #1 thing I took into consideration when considering the tools in this list.

➡️ This includes how these AI rewriters kept up the same meaning with different wording.

#2: Being able to refine and update your output

Considering that AI rarely gets the job done from the first go, it was important to me to see article rewriters that let me refine and update the output.

#3: Cost of the sentence rewriters

Although the bulk of AI sentence rewriters are free, I also considered more advanced paid options that can help you rewrite sentences for different clients without creating duplicate content to your existing or competitors’ articles.

Team-GPT offers the best place to rewrite your sentences because our tool lets you rewrite sentences at scale with our Pages.

Here’s how you can rewrite sentences with Team-GPT alongside your team:

Step #1: Create a new Page inside Team-GPT

Team-GPT’s Pages are a place where you can collaborate with your team on paraphrasing sentences and optimizing your content.

Start by navigating to ‘’Pages’’ on the left-hand side menu and click on ‘’New Page’’ on the top right of the page.

Team-GPT’s Pages work similarly to how Google Docs would, as you can paste your content and start working on it alongside your team.

Step #2: Paste your content and start paraphrasing sentences at scale

You can paste one sentence, multiple sentences, or an entire article, and then you can double-click on a sentence and paraphrase it in a different style.

There are 5 different types of sentence rewriting:

• The usual paraphrasing in English.
• Persuasive rewriting.
• Formal rewriting to formalize your content.
• Casual rewriting to turn your formal content into casual.
• Rewriting without adjectives to make it shorter.

Apart from that, Team-GPT offers 3 things that other sentence rewriters do not:

• The ability to customize tools like ChatGPT and Claude to rewrite sentences like you if you choose to use an AI generator for rewriting.
• A prompt builder, which will help you refine your sentence rewriting prompt to fit with your content.
• Being able to collaborate with your team on sentence rewriting so you can learn from prompts from one another and save your best prompts.
