Mention online grammar checkers, and for most people the first name that comes to mind is Grammarly. I had an annual subscription for years, but this year I cancelled.
So what grammar tool am I using instead?
Quillbot.
Why?
Because with Quillbot, I have access to more features than Grammarly at nearly half the cost, with more tools to boot.
So what is Quillbot?
Quillbot is an AI-powered paraphrasing tool that helps users rephrase and rewrite text in a more natural and coherent way. It also offers advanced features such as grammar checking, a contextual thesaurus, and tone detection.

For example, if you don’t like what you wrote, use the paraphrase tool. Here is how Quillbot paraphrased my introduction:

What grammar tool do I use in its place, then?

Who Is Quillbot Not For?

I am not a fan of the AI Writers that supposedly write blog posts and other content in minutes. I have reviewed those products in numerous posts. Even the latest versions create content that is poorly written and inaccurate–check out Are Exclamation Marks Flirty if you don’t believe me.
Quillbot also uses AI technology, but not in the same way. I can ask for a suggested sentence starter or have it flesh out a paragraph. But it won’t take a prompt and write an article. Instead, I use the research function in the co-writer to do the research. The sentence suggesting tool helps me to improve my writing by providing suggestions for better word choices and sentence structures.

Disclaimer: I paid for and use this tool. I wouldn’t recommend it otherwise.
