When I was looking for a similar tool, a friend recommended one to me and tried it out for 5 minutes. Personally, I think it's pretty good. It's pretty simple. Personal knowledge base is a thing for people like me ---- read a lot of web pages every day, but sometimes after reviewing it but can't remember anything. I especially like the reading plan in it, which can help me correct the habit of only collecting and not reading... Recommended Recommended ~ :p
