Userback (https://www.userback.io) is a visual feedback tool for websites. It's very easy to use and is a great way to get visual feedback from any web page. You simply add the feedback widget to your website (or use the browser extension) and take annotated screenshots with your feedback. It also integrates with tools like Jira, Slack and Trello which saves a lot of time when it comes to managing feedback.

Full disclosure: I now work for Userback but was also previously using it for years in previous roles. It's a great tool :)
