Dropbox seems to be testing an online note-taking application called "Project Composer." No, we don't know if that's going to be its final name, but that's at least what has appeared to those who tried to access a link to the service that was posted on Product Hunt a day ago. And, yes, Dropbox has since adjusted the URL, blocking any future attempts at checking out Composer by unauthorized users.

According to those who initially tried to see just what, exactly, Composer was, clicking on the link to the allegedly "limited access" service first pulled up a prompt that asked potential users to allow "Composer" access to the files and folders in their Dropbox accounts. Some users were able to link up—or, at least, attempt to go through the process—only to find themselves greeted with an error message: "Sorry, you're not allowed to use Notes right now."

Here's where things get interesting. Last year, Dropbox acquired an online note-taking service called Hackpad. The service still works, but it's widely thought that Dropbox's "Project Composer" is its new Hackpad variant that is more tightly integrated with Dropbox itself. Helping to confirm that theory is the fact that one former Hackpad user was actually able to successfully link her Dropbox and Composer accounts—and in doing so, gain access to the service.

"Really nice so far—some beautiful (beginnings of, it's a bit of a mash up at the moment) typography and very clean interface (reminiscent of evernote's web experience). It allows multiple people to work on a note. You can add tasks, images, dropbox files, tables all in line with your notes. It also prompts you to create a note for a meeting based on what's on your calendar," described Maggie Bignell in a Product Hunt comment.

"I can see this being useful in meetings/taking notes together. A bit hard to evaluate how the interaction will stand up when I'm not actually in a meeting/interacting with others on the app, but given we use google drive for a similar use, this could be a valuable switch."

According to TechCrunch, Dropbox will allegedly have more information about Composer "soon," though it's not ready to talk about it just yet.
