"ZSXQ" (Knowledge Planet) is an excellent knowledge community with many high-value niche groups. The information quality here is often much higher than what you find through search engines like Google or Baidu, making it a great way to quickly dive into a new field. It's one of my favorite knowledge tools.
However, ZSXQ has its drawbacks—the biggest being its poor search functionality. For instance, you can only search for keywords within a planet, but you can't filter the results to show only posts from the "Planet Owner" (the group creator) or specific contributors. This results in a lot of noise, making it hard to find high-value content and slowing down the learning process. Given ZSXQ's business model, the Planet Owner's posts usually contain the most valuable insights—after all, that's why you paid to join.
To address this, I created a tool called Planet Assistant. It allows you to download posts and files from your joined planets to your local computer, where you can perform much more precise and efficient searches.

Below are two images comparing search results from Planet Assistant versus the official ZSXQ website.


Currently, the software is simple yet effective, focusing on two core features: "Sync" and "Search."
