Evernote Alternative for Group Projects

[Sparced]

I'm involved in a group project in Uni working on a documentary.

I need a solution where I can easily save web clips, images, links to videos into a folder system and have it assessable to everyone in my team without paying a subscription charge.

I've used dropbox in the past but it would be nice to have something like Evernote that's got a nice interface with previews.
