Trueskill Ranker

What is it?

Trueskill ranker is an open-source web app that uses the truskill ranking system to help you sort a list of items, by comparing them two at a time. This is an improvement on elo ranker since it prioritizes comparison of items with similar ratings and low "confidence", which effectively means you can get an accurate rating much faster. It also allows you to add a new item to an already ranked list, and will quickly find its place.

You can use it to rank your favorite movies, songs, books, TV shows or even prioritize your tasks or startup ideas!

How to use it?

To start, you can add items either using the "Add" button one at a time, or "Paste List from Clipboard" to add multiple items at once by copying a list where each item is on a separate line (Note! this function will erase your existing list). After adding at least two items you can start rating them by picking your favorite out of two at a time!

You can also save your rankings to a .json file, and later load them in another computer or browser.

The progress line is a function on average confidence of the rating. Since you can never be 100% accurate, this will never reach a 100%, but approaches it as sigmas approach 0. I found that anything above 50-60% is usually good enough to share.
