Hello Reza,
Pie is a wonderful tool for sharing stuff and organizing information around a shared document.
Hubgets, however, is doing a bit more than that in terms of functionality. Alongside with indexing information, using hashtags and mentions, each string in the communication in Hubgets also gets a permalink. The permalinks help retrieve the exact time and place when a piece of information was generated, so that traceability is complete.
Hubgets imposes no limitation for file size or file type. Each file name is indexed and easily searchable.
In Hubgets, filtering of information is done in real-time, and you can see the filtered details in the left side panel.
