User experience matters when you’re collecting feedback. Content Kit makes it quick and easy for users to leave feedback and follows best practice design.

Minimize frustration to maximize feedback. Users hate being interrupted with popups and wordy surveys. Content Kit offers an alternative that’s there when they need it without getting in the way.
Feedback options 
Users can express their thoughts and feelings in a way that works for them, whether that’s a rating from 1 to 5, a thumb up or thumb down, or general comment on a page.
Anonymous 
Reduce friction for users to leave feedback and protect their privacy. By not collecting personal information, it’s a lot easier to comply with data protection requirements.
<h3>Why Content Kit</h3>
Content Kit is the easiest way to collect feedback and gives you everything you need to start improving your site.
Highlight and react 
Our unique text-highlighting feature allows users to leave a thumb up or thumb down reaction. Highlighting helps to pinpoint the problem so you know exactly what the user is referring to and what to fix.
Privacy
