Textseed is a project by one of my friends which I want to present to you.

What is Textseed?
To quote the landing page, Textseed is a more organic way to write your documents! Let your documents and thoughts grow through other’s people’s contributions, just as flowers grow when receiving sun and water.

What does it do?
Textseed gives you the opportunity to write texts together with your friends or colleagues and to keep track on who wrote what.
If your team has to complete a report or argues about the discussion items for a presentation, it can happen on Textseed in an organic way.

Textseed is meanwhile stable and the text editing functions are complete.
Up next it will be possible to invite people to your projects and to export your documents as PDF via a LaTeX bridge.
