Reddit Votify is a free Chrome extension developed by kevinvincent. It falls under the category of Browsers, specifically Add-ons & Tools. This extension aims to bring back upvote and downvote counts on the front page of every subreddit.

The way it works is by crowd-sourcing the "% like this" and total score for all submissions and storing them elsewhere after computing the upvotes and downvotes using an algorithm. This algorithm was provided by /u/bxtk, who generously shared code samples.

One of the main features of Reddit Votify is the live updating of upvotes and downvotes. This means that users can watch the vote count change in real-time without having to reload the page. This feature adds a dynamic element to the browsing experience, allowing users to see the popularity of comments and submissions as they are being voted on.

Overall, Reddit Votify is a useful tool for Reddit users who want to have access to upvote and downvote counts directly on the front page of any subreddit. With its live updating feature, it enhances the browsing experience by providing real-time information on the popularity of posts.
