Nickstory is a free Chrome add-on developed by Kyler123. It falls under the category of Browsers and the subcategory of Add-ons & Tools. This program is specifically designed for users of the Korean website, Lurie Web (루리웹).

Nickstory allows users to track their nickname change history and assigns a "ㅋ grade" to each nickname. All records are stored locally, and if the add-on or browser is deleted, the records will be deleted as well. As users continue browsing, if they come across a different nickname for the same ID, the oldest date of discovery is automatically updated and displayed. Users can export or import their records and "ㅋ grades" if they want to move them elsewhere or keep them.

In addition, there are ▽△ buttons located after comments, which allow users to adjust the "ㅋ grade" for a specific ID, ranging from 0 to 10 points. The "ㅋ grade" is a way for users to rate others based on their preferences. Depending on personal judgment, users can assign a "ㅋ grade" to people they like or dislike. The number of "ㅋ"s added after a comment is determined by the "ㅋ grade" number.

The latest version of Nickstory, V1.3, includes general bug fixes and optimizations for storage usage. It also introduces "unlimited storage" for heavy users who have a large database and will quickly grow their records.
