Writesonic, on the other hand, creates brand-new content for you. Just give it a few keywords, and its Article Writer can create a whole blog post. It has over 100 templates for things like product descriptions, ads, and social media. When we tried it, we generated a 2,000-word article in under five minutes. For creating new content from scratch, Writesonic is the clear winner.

Paraphrasing and Rewriting

When it comes to rewording your text, this is where QuillBot is the star of the show.

QuillBot gives you ten different modes to get the perfect tone, whether you want to sound professional, creative, or simple. If you have the premium version, you can rewrite entire documents without limits. We tested it on some tricky technical content, and it did a great job keeping the context right.

Writesonic has a rewriting tool, but it’s much more basic. It’s fine for a quick, simple change, but it doesn’t have all the powerful options that QuillBot offers. For any serious rewriting job, QuillBot is the hands-down winner.

SEO Optimization

Want your content to show up on Google? This one’s an easy decision.

QuillBot doesn’t really do SEO. While making your writing easier to read is a nice bonus for quality, it doesn’t offer any real SEO tools for keyword research or checking out your competition. You’ll need something else for that.

Writesonic is packed with SEO features. It helps you with everything from keyword research and analyzing your competitors to running site audits. It even has a super smart tool on its bigger plans that watches when your brand is mentioned on AI chats like ChatGPT. For anyone serious about SEO, Writesonic is the only choice here.

Brand Voice and Tone

Do you want your AI to sound like your brand?

With QuillBot, you have a couple of options. You can use the standard modes like ‘Formal’ or ‘Creative’ to change the general feel of your writing. But if you have the premium version, you can unlock Custom Modes. This feature lets you define your own unique voice with a simple word, like ‘Witty’ or ‘Confident,’ so the AI can learn your specific style.

The citation generator supports MLA, APA, and Chicago formats—essential for academic work.

Writesonic has some basic checking tools, but they’re not its main focus. The tools catch obvious mistakes but lack QuillBot’s editing sophistication. For error-free, properly cited content, QuillBot’s specialized capabilities prove more reliable.

Integrations

QuillBot integrates with Chrome, Edge, Safari, Microsoft Word, and Google Docs. Mobile keyboards for iOS and Android enable on-the-go editing. These extensions work seamlessly in everyday writing environments, though they don’t connect with marketing platforms.
