We have an extension (for chrome) and a bookmarklet (and ipad app) that use pdf.js to add comments to pdfs and save specific pages from pdfs. The extension and bookmarklet allow commenting on any page that can be rendered on a web page (including Pdfs!).
We are now targeting it for education.
Will love feedback (provided our site doesn't crash)

#23Can this app be an item in the "chrome://apps/" page, and use my google credentials for logging in? Or some form of OpenID?
We're working on adding Google Login at the moment. You can install the App version from https://chrome.google.com/webstore/detail/notable-docs/iljoj... , although it doesn't support offline at the moment.

#24How long take to make it? How many persons are in your team? Is it a kind of side project?
The MVP took about a month, and probably 3 months to polish. Working full time with 2 hackers, hipster and a hustler.

#25Hah, the layout is almost exactly like a thing I'd developed last year: comment threads on the right, callouts into the document on the left. Pretty cool--if anyone's interested, I'll try to get the source code released.
Yes. Would be a great starter for a project I am working on.

#27its kinda "funny" how pdf.js is used for Chrome in a way that only works with chrome. (given that it comes from firefox) thanks for walled gardens google!
Huh? How so?

#28This app caused me a lot of trouble. I tried to save some PDFs and they were impossible to open in any reader. I opened them with Notepad++ and they were now HTML files. Also, there is security issue of giving full access to your PDF downloads away. Sometimes financial institutions generate PDFs with account and identiy information; this app by default doesn't ask you if you want to give it to them, it just automatically does so.
I like the concept and hope to download a future iteration. Just some feedback.

Sorry you had trouble with saving PDFs - I'll look into it and see if we have a bug there.
We don't actually upload the PDFs to our servers unless you explicitly use our 'share' function. This is something we consider critical to the product, for the privacy reasons you mentioned. We do send a fingerprint of the document to our servers to check if anybody has added comments to it. (The comments you make are saved to our servers however).
Hope this answers some of your concerns, feel free to email us at support@notabledocs.com if you have any other feedback
