What is the benefit of creating a web app that only works in 1 particular browser? Or is this not a web app?

The extension is currently only available for Chrome, but all the functionality is available at http://web.notabledocs.com/web/viewer.html - If you share your document, that's what the other people get. We actually work offline (including making comments) if you install the extension.

Cool stuff! Something I've been thinking about too. Open Source?

This is EXACTLY the product I wanted to make, thanks! I think a use case for which you could sell it is collaborative class note-taking. My teachers distribute PDFs of their lecture slides before class which students use to take notes on (so that they don't have to recreate figures, etc). I have always thought it would be great for this PDF-markup process to take place live in some sort of Google Doc interface. This…

We actually made that product first! - http://www.notable.ac is similar, but made specifically for students, documents are organized by course and notes can be made public/private/shared with friends.

It does take a bit more work to setup, because you have to upload the documents to the site first (we process them into images on the server, and support Word/Powerpoint as well as PDF).

We had trouble getting traction in the education space - So we built the Chrome version, which works much better for single documents and for uses outside education. But we're still keeping notable.ac running so feel free to give it a try.

Not right now, but it's something we're considering - we certainly owe a lot to Mozilla's PDF.js, which is doing the PDF rendering for us. It's just tricky to decide to give away the code when you don't yet know what part of your startup is (hopefully) going to be valuable.
