An internal combustion engine (ICE) is a heat engine in which the combustion of a fuel occurs with
an oxidizer (usually air) in a combustion chamber that is an integral part of the working fluid
flow circuit. In an internal combustion engine, the expansion of the high-temperature and
high-pressure gases produced by combustion applies direct force to some component of the engine.
The force is applied typically to pistons, turbine blades, a rotor, or a nozzle. This force moves
the component over a distance, transforming chemical energy into useful work. This replaced the
external combustion engine for applications where weight or size of the engine is important.

 Other online paraphrasers: high plagiarism scores

Google's top-ranked paraphraser scored at 47% plagiarism ....

 Speedwrite: A perfect score

... Speedwrite scored 0% plagiarism for the same text....

... But that's not the only reason Speedwrite is a better paraphraser....

Unlike the others, Speedwrite actually writes with great style. Other paraphrasers either produce bad writing, or writing that is just total nonsense gibberish, not even English. Speedwrite is the only paraphraser that generates really good text, with well-formed, intelligent paragraphs. Let's look at an example:

 Other online paraphrasers: terrible writing

Ugh. That is really just not good English ....

 Speedwrite: really excellent writing.

That's really good writing, actually....

...And other paraphrasers have problems with repetition....

 Other paraphrasers don't modify the length of your input. You get paragraphs that are nearly exact duplicates of your input paragraphs. It's obvious that the output paragraphs are derived exactly from the input paragraphs...

Hm.... clearly an obvious copy....

 Speedwrite is the only paraphraser that intelligently re-writes your input, to make new, original text....

Now, that's what I call an intelligent rewrite....

Other paraphrasers write text that is only good for computers to read....

 Look what happened when we put this text into Google's #1 search result for "paraphrase"....

That output text on the right is really bad. It wouldn't make sense to a human.

  Compare that to what Speedwrite creates, from the same input...

Speedwrite's output is a well-written, original paragraph!

Got some questions?

Is this paraphrase webpage, that I'm on right now, the same thing as Speedwrite?

This page is a demo of Speedwrite, a paraphraser designed to work on all devices, to show you what Speedwrite can do. For serious work, please use the primary Speedwrite application. It works on any computer, like   Windows,  Mac,  Linux, and  Chromebook. It's a lot faster to use, allows for longer inputs, more than one paragraph generation at once, loading and saving of documents, and more.

Is there a maximum length of text that I can paraphrase?

This page is only a demo -- the text box at the top of this page can accept only one paragraph. To use longer-length text, please move over to the Speedwrite application, here.

What kind of text should I paraphrase to make great original text?

Start with clearly-written creative-commons text, like text you might find on Wikipedia. Don't input text with errors or incomplete sentences. Speedwrite has to figure out what each of your input paragraphs is "about" -- to help it out, each paragraph that you paraphrase should be focused on only one subject.

Is Speedwrite guaranteed to produce totally unique output each time?

No. But actually you should find that the outputs are very close to unique when measured over a period of time. Please see the relevant entry on the How It Works page.

Why do I need to paraphrase?

Using Speedwrite, you can take any creative-commons text, such as articles, scientific texts, Wikipedia pages, and more, and paraphrase them into unique writing, that the world has never seen before. This process happens automatically, using new technology developed by Speedwrite.

A Speedwrite paraphrase will extract the important points from the text that you enter, but re-write it each time to generate a unique output text.
