It’s always best to properly cite your sources and ensure your writing reflects your understanding.

Can you trust QuillBot and Grammarly for grammar checking?

Mostly yes. I would strongly recommend double-checking the text you are correcting with these tools, as they may not always understand the full context if you are creating more complicated sentences.

But for simple, short sentences they are great and require very little or no correction.

Which is better: QuillBot vs Grammarly?

Grammarly is better as an integrated browser extension and is a great grammar checker, while Quillbot has more features like citation and summary AI tools and is better as a standalone app.

Which is better: QuillBot vs Grammarly?

Grammarly also has a cleaner interface and does not have any problems using Chrome or other browsers. Quilbot has a less user-friendly interface than Grammarly.

While these tools won’t improve your writing skills and won’t launch your freelance writing career, they’re great for people who want to write text and think about how to fix it later.

In the end, choosing between Grammarly and Quillbot depends on what is more important, but in essence, they are both great writing assistants and can be used to great effect with content creation tools. I would recommend trying them both out for yourself as they both offer great free plans.

If both QuillBot and Grammarly don’t meet your needs, consider hiring a company that specialises in building custom AI tools and AI automation.
