Grammatically speaking, a complex sentence is simply a sentence that contains at least one independent clause and one dependent clause. A complex sentence generator simply helps you rewrite sentences, sort of like a paraphrasing tool.
We think the confusion comes down to the search intent behind people looking for complex sentence generators. While from a grammar perspective, a complex sentence is one thing, most native speakers would simply want to find a tool that can help make a generic, boring sentence more complex with a better selection of vocabulary.
Complex sentence generators rewrite sentences
We reviewed and tested the top 5 best complex sentence generators on the internet. They are a mix of free and paid-to-use, and will give you a large number of different sentences with just the click of a button You can generate topics for your writing assignments or even blog posts if you need some inspiration.
Please note that these “complex” sentence generators simply mix up the vocabulary and use synonyms to make a simple sentence more interesting an complex (but not from a grammatical standpoint of adding on an independent or dependent clause).
The sentence we will be using in this example review
For this review, we will be using a few different generators and will be using the same sentence each time to keep things fair. Our sentence will be a proper complex sentence with an independent and dependent clause:
“Brian was happy to have ran in the race, even though he didn’t win.”
Jasper AI – The best professional writing assistant tool
This the writing tool we use here at Teach and GO to help us create student feedback, write rough draft essays and help out with blogging aspects like creating good meta descriptions and compelling titles.
While not a replacement for hiring a competent writer or doing the writing yourself as a professional, it is a seriously big help and tool we think is essential for any teacher needing to write essays, research papers and more.
So, how did Conversion AI do? Let’s find out:
Jasper AI for the win. This rewrite happened at the click of a button. If you did not like what came out you simply click the blue button to make it try again. But this rewrite is great. It’s better than the original but not over the top with overly verbose language. What’s even better is that Conversion AI allows you to rewrite entire paragraphs, not just sentences.
It also comes with a content improver, paragraph generator, sentence expander, intro and conclusion paragraph creator as well. Overall, we find this AI writing tool to make writing easier and less mentally taxing.
From long-form teacher reports, essays for professional education, blog posts, and more, we’ve found Jasper AI to be incredibly helpful.
Jasper AI
An AI writing assistant that speeds up your writing. A great choice for any teacher looking to write faster and easier. Easily paraphrase sentences and paragraphs at the click of a button. Create content faster and more easily than ever before.
Pros:
-Write content faster and more easily.
-Well written, grammatically correct sentences created by the AI.
– A suite of tools for all types of writing, from YouTube video descriptions to novels.
Chat GBT – The best free option
Chat GBT from Open AI is going to revolutionize content creation. It’s a powerful tool where you can input commands to the AI to create sentences, paragraphs, stories and even write code. When using Chat GBT it is essential you give it prompt commands so it knows what you want it to do.
For this example we used the [rewrite] prompt so the AI would know to rewrite a complex sentence. Here is how it performed:
A very good output from Chat GBT. It makes sense, is still complicated enough and it is a unique take. If all you’re looking to do is quickly rewrite sentences and paragraphs using the rewrite prompt function should be acceptable enough for most uses cases.
The only issue is you need to understand how to use prompts to get it to write something unique because it will paraphrase in the same exact way any paragraph or text you give it. It’s not like you’re going to get a unique piece of content compared to someone else.
However, if you’re looking for something free that’s quick and easy you can’t go wrong with ChatGPT.
Our favorite prompt to get started rewriting and paraphrasing a piece of text is:
“Please paraphrase [insert content]”
You can obviously expand on this prompt to your liking with adding in how the content should be presented, they types of words used as well as the specific audience you’re paraphrasing for.
CS Generator – An acceptable free Option
CS Generator is usually one of the top 3 sites that will pop up when you go looking for “best complex sentence generator” and for good reason. It makes a boring sentence more complex with better vocabulary.
Take a look at the results we got below:
Overall not bad for a free tool. We liked the use of the word “jubilant” and “albeit” which are two under used words as a way to express emotion. As you can see, CS Generator simply rewrote the sentence and swapped out some words.
For a free tool where you need to rewrite a sentence or two it’s a solid choice, but if you’re needing a lot more power and flexibility then we strongly suggest checking out Conversion AI (also known as Jasper).
Quillbot – The classic rewrite tool
When it comes to online generators and writing tools, Quillbox is a free browser-based tool that tends to show up whenever there’s discussion about online writing assistants.
It has a good reputation for being one of the more user-friendly generators, and it’s definitely one to consider. Best of all, it’s totally free to use. So how does this perennial option stack up?
Fantastic results out of Quillbox. In particular, we like how they keep updating and improving this tool for writing complex sentences. Now you can adjust the style of writing from creative to formal as well as adjust the synonyms. Though that last feature is locked behind a paywall.
SEO Tools Centre – A mediocre option
So at the bottom of the list is SEO Tools Centre. They provide a few different writing options with regards to paraphrasing tools, a comma checker and their complex sentence generator but compared to the other options on the list for creating more complex sentence they were average:
The choice of using “within the race” is simply not correct and is something that perhaps a non-native speaker would write or say. As such, this tool is not efficient as you’ll need to rewrite the rewrite it provides.
Lingo Jam – A good, simple tool
Last is Lingo Jam. It’s very similar to CS Generator and produces similar quality and similarly written sentences. As such, there is nothing that really stands out about using this tool. But if you’re looking for a free alternative to Conversion AI or just something different that CS Generator it’s a decent choice. So how did it do? Take a look:
Lingo Jam decided to throw in jubilant but it did not change the dependent clause of the sentence. Overall it simply changed one word. Not exactly what we were expecting from an online tool.
Best online online complex sentence generator for compound sentences and more
Overall we here at Teach and GO are sticking with Conversion AI for out complex sentence, rewriter and expander tool. It’s a paid tool, but it’s incredibly helpful for what we do, writing content. If you’re looking to just rewrite a sentence or two here and there then obviously you’ll want to stick to Chat GBT.
But if you’re a professional teacher who’s doing a lot of writing we strongly suggest you test run Conversion AI and both Chat GBT to see which work flow you like more. With Chat GBT you have to understand how to use the prompt function, otherwise you’ll end up with a lot of repetitive content.
