The new RegretsReporter extension gives you more control over your YouTube experience. RegretsReporter brings YouTube’s algorithmic controls to the forefront of your feed, giving you a simple way to tell YouTube’s algorithm to stop recommending certain videos, and also to report the recommendations that you regret.

This extension is part of a crowdsourced investigation into YouTube’s algorithm to learn more about what people regret being recommended and how the algorithm responds to user feedback. You can choose to opt-in to donating your data to support our research upon installing the extension. By contributing your data to our research you can help us improve one of the most powerful recommendation engines on the planet.
