Free AI rewriters are everywhere. If you type ‘best free AI rewriter,’ you get over 2 million search results! The question now is which ones are actually ‘free’ and ‘best’ and which ones are impostors.
I tested a handful of free AI rewriters (no sign-ups, no emails, no credit cards) using different paragraphs and topics. Some impressed me while others, well, let’s say that there is a massive room for improvement.
Stick around to find the one that could seriously upgrade your writing game, without costing a dime.
Originality.ai Paragraph Rewriter
Website: https://originality.ai/blog/tool-paragraph-rewriter
I’ll be honest, it’s surprisingly good for quick rewrites, and you don’t have to exert too much effort.
Just paste your text, pick a tone (like Professional, Humorous, or Conversational), choose if you want it longer or shorter, select a language, and hit Rewrite.
That’s it. You’re done in seconds.
Quick Test
Original:
“Bioluminescence is the ability of certain living organisms to produce light through chemical reactions within their bodies.”
Rewritten (Humorous, Expanded):
“Picture this: some creatures basically have their own built-in nightlights. Yep, thanks to wild little chemical reactions, they glow in the dark. Nature’s got jokes.”
What I Liked
- Tone Selector: You can make your text sound smart, silly, serious, whatever fits.
- Advanced Mode: Toggling the ‘Advanced mode’ allows you to tweak the voice either to passive or active
- Instant Results: Zero wait time.
- Absolutely free: You don’t need an account to test it out.
- Multi-language Support: Handy if you’re writing in languages other than English, such as Spanish, French, etc.
- Comparison View: You can compare the original and new versions.
Where It Falls Short
- Character Limit: You can’t choose an exact number of characters.
- No Tips or Suggestions: You get a rewritten paragraph, but no “why” behind the changes.
- Limited Customization: Cannot provide specific instructions, such as “make this more SEO-friendly.”
- Limited tries: Just 20 free tries per day.
Wish List
If I could change a few things, I’d add:
- A box to explain my rewriting goal (e.g., “Make this sound persuasive”).
- A quick AI note on why specific edits were made.
- Built-in plagiarism check.
Ahrefs Free AI Sentence Rewriter Tool
Website: https://ahrefs.com/writing-tools/sentence-rewriter
You might know Ahrefs for its Search Engine Optimization tools. But did you know that they now have a rewriting tool?
Just paste your sentence (up to 2048 characters), pick a tone (there are 15, including a custom option where you can type “Sassy,” for example), and select your preferred output format, paragraphs or bullet points. You can even choose how many of each. Oh, and you get up to 5 rewrites in one go. And, yes, you can even export the results.
Quick Test:
Original:
“The name comes from French, from the childish repetition of bon (“good” or “delicious” ): bonbon or bon or bon, which became bombón in Spanish.”
Rewritten (Luxury Tone, 2 Paragraphs):
“The term originates from the French language, stemming from the playful repetition of the word bon, which translates to ‘good’ or ‘delicious’. This evolved into bonbon, or simply bon, and eventually transformed into bombón in Spanish.”
“The name is derived from French, where it is a playful reiteration of bon, meaning ‘good’ or ‘delicious’. This led to the creation of bonbon, or just bon, which later became known as bombón in the Spanish language.”
What I Liked
- Tone Selection: From Professional to Playful to Custom, you can even type your own tone, like “Wild”.
- Format Options: Choose between Paragraph or Bullet Style, up to 3 paragraphs or 10 bullet points.
- Multiple Variants: Get up to 5 rewritten options in one click.
- Multi-language Support: Rewrites are available in multiple languages, making them ideal for creating multilingual content.
- Export Feature: Download or copy your rewrites for easy use.
- Modify Button: You can modify the results by clicking this button, and it will expand options like rephrase, expand, shorten, and translate.
Where It Falls Short
- No Custom Rewrite Goal Field: You can’t explain why you’re rewriting.
- No AI Feedback: You get results, but there’s no explanation of what changed or why.
- No Side-by-Side Comparison: You have to compare the original and the rewritten outputs manually.
- Character-Limit Only: There’s a cap on how much you can paste, but you can’t target a specific word count.
Wish List
If Ahrefs adds a few things, this could go from good to great:
- A box to explain your rewrite goal
- Short AI blurbs explaining major edits
- A plagiarism scanner
- Highlighted differences between the original and rewritten text
