YouTube Comment Picker
Draw a giveaway winner from a video's comments — one entry per channel, filtered by your rules. Every draw comes with a seed, so you can post the result and anyone can re-run it and get the same winners.
Free users get 2 draws per day, 100 comments each. Sign up for more.
Two things this tool will not pretend to do
It cannot check that a winner is subscribed. YouTube only reveals someone's subscriptions to an app that entrant has personally signed into — not to the channel owner, and not to any API key. Every picker offering a "must be subscribed" checkbox is ticking a box that checks nothing.
It draws from the comments it read, not from all of them. YouTube hands out comments 100 at a time and this tool stops at 500, in YouTube's relevance order rather than at random. On a video with 50,000 comments the draw is fair over that sample and not over everybody — which is why the proof block says so in the copy you post.
