TrendRadar: Aggregate Hot News from Multiplatforms and Push to Instant Messenger by Keyword

TrendRadar is a tool that helps users aggregate hot information from multiple online platforms, aiming to solve the problem of information overload. It automatically monitors the hot search lists of more than 35 platforms, including Today's Headlines, Baidu, Weibo and Zhihu. Users can set keywords they care about, and TrendRadar will filter out news related only to those keywords and generate an analysis report with the results. This report can be pushed directly to the user's cell phone through various channels such as Enterprise WeChat, Flybook, Nail or Telegram for quick alerts. The most important feature of this project is the simplicity of deployment. Ordinary users don't need programming knowledge, they just need to perform simple operations on GitHub, and they can deploy a web version in as fast as 30 seconds, and set up mobile notifications in 1 minute. It allows users to shift from passively receiving algorithm-recommended information to actively getting the news they really need.
