How to draw a winner with a comment picker in steemit

Hello all.
Today I want to introduce a tool to take comments at random for your giveaway event.
Before we get started, you can check the giveaway I'm doing in steemt here :

okay, first make a contest in steemit with the policy of the contest followers should comment as you oblige.
for example, if you want to participate in this contest, each contestant is obliged to nominate sequence number 1,2,3 and so on.
If so, give time for 2 days to gather the contestants.

and insert a time link without using steemit.com
look at the example below.
https://steemit.com/giveaway/@erikkun28/giveaway-spotify-premium-account If all the contestants are enough. Visit the site http://pick.esteem.ws/

Finish, you can hold a contest and can choose the winner with the fairway.
Good luck with your contest.
don't forget to upvote, comment, and resteem.
