Request for your comment on my first officially launched Chrome extension

hi guys, I have developed an on-site seach and Q&A tool. Its function is very simple. do on-site search and answer your question about the web you are browsing. I assume it maybe helpful for user who is struggling with the poor in-site search engine of complex websites. So may I ask for your comments on it, my dear HN community friends? If you are insterested, please give a try. Thanks a ton.
