An idea about create your own links anywhere, any message type

Here is my idea:

I wanna build a tool which is able to set your own links anywhere you want. It can be when you browse on BBC website, come across a special phrase, then you search on google, find the meaning for that, and you want to give it a remark so that review it next time when you see it.

Not just text from website, it can be any message type, like pictures, videos, even a song which type is mp3, you can still build a link for that.

So, this is something like bookmark, but it's much more power and useful than former one.

I hope anyone who is special interesting in my idea and able to develop this tool with me.
