Description

With Uniq4o you can calculate the percent of uniqueness of any two articles. Just paste them in the two textareas and hit Compare. There is a limit of 10 000 characters. The HTML is stripped.

Note that even completely different articles can result in between 70 and 100% uniqueness. Also keep in mind that you should not compare the result from this tool with other similar tools, only compare results from the same tool. Based on my research I have made several levels of uniqueness that will help you understand the results from this tool:

• Above 69% - Completely different (also possible to achieve with spinning + paragraph shuffling/removing).
• 50% - 69% - Very high level of spinning (spinning + paragraph shuffling/removing).
• 30% - 49% - High level of spinning.
• 20% - 29% - Medium level of spinning.
• 10% - 19% - Low level of spinning.
• 5% - 9% - Very low level of spinning.
• 1% - 5% - Almost the same.
• 0% - Exactly the same.

My thoughts on spinning

I also want to mention that I don't use article spinning anymore. I have done it in the past and I can say that no matter what it always leads to lower quality content and user experience. Now I only use Uniq4o to find out if a given article is a copy of an article of mine and how much. It is useful to do that after I find copies of my content with Twin4o to see are they exact copies or not.

Version History

Uniq4o 1.2.7 - 4 November 2013

- Improvement - One small additional protection against random bots has been added.

Uniq4o 1.2.6 - 17 October 2013

- Bug fixed - You can now open Uniq4o in multiple tabs/windows at the same time without getting an invalid request error message when you click the button.
- Improvement - Proper error message is displayed if one of the text fields (or both) are empty (before it just said 100% uniqueness).
- Improvement - Requests with empty referer are now allowed. This is just in case some people are using software to remove their referer for security measures. (Requests still require a security token though, so fake ones are still caught).
- Improvement - Few small improvements to the programming code are made (like removing unnecessary parts and combining two functions into one).

Uniq4o 1.2.5 - 6 September 2013

- Improvement: Appropriate error message is displayed when the request is invalid.

Uniq4o 1.2.4 - 29 August 2013

- Bug fixed: The result layer at the top was too big in Internet Explorer 7.
- Improvement: Small adjustments to the font size and the paddings of some layers.

Uniq4o 1.2.3 - 3 May 2013

- Improvement - The animaton, showing the result, is now set on much faster speed.

Uniq4o 1.2.2 - 11 November 2012

- Improvement - A better way of program versions numbering. Three digits are used now. The first is the major version, which will change only when huge changes are done. The second will change when smaller changes are done, new features are added and so on. The third digit will change if the only changes are bug fixes and very small or not visible improvements.

Uniq4o 1.2.1 - 31 August 2012

- Improvement - Various security improvements.

Uniq4o 1.2.0 - 11 July 2011

- Improvement - Only two images are used for all 13 animals that represent the different uniqueness levels. Different parts from them are displayed with CSS positioning of the background image.
- New feature - Loading animation is displayed instead of the button, while the script is working and after that the button is displayed with jQuery effect.
- New feature - jQuery effects when showing the result.
- New feature - AJAX loading of the page, which means, there is no reloading of the page when you click the button.
- Bug fixed - If there was one less than character "<" somewhere in the text, all the text after it, was considered HTML and was stripped. Now this is fixed. (Still HTML is not allowed and everything between "<" and ">" is removed.)

Uniq4o 1.1.0 - 15 June 2011

- New feature - A link used to clear each textarea and give focus to it. Makes a little faster pasting the text there.
- Bug fixed - When there were single quotes or double quotes, or "\", they were automatically escaped and "\" was added in front of them.

Uniq4o 1.0.0 - 09 June 2011

- Initial release.
