Tidio lets your visitors chat with you through your site, and has a free package that allows up to three operators to chat to an unlimited number of visitors. You can run a desktop application or a mobile app, which will notify you when a visitor starts to chat.
A visitor to your site will see a chat tab attached to the bottom-right corner of their browser window, as shown in figure 1.
