Top Web Annotation Tools: Annotate+Bookmark+Collaborate shared copyIn case you never came across any ‘Web Annotation’ service before, than basically what it is, is a bookmarking tool (usually in the form of browser addon or bookmarklet) that allows users to annotate (add sticky notes, highlights, etc.) any desired webpage and store it online.


There are many cool things you can do with them, i.e. (1) quickly add sticky-like memos to your bookmarks, (2) bookmark long articles with relevant text being highlighted, (3) store, organize and tag annotated pages online and most importantly (4) share your annotations with friends or project/assignment group members.

    We love the idea of a universal, cross-website content platform, a way to 'mash up' sites. But we disliked the implementations in these kinds of web annotation services. We didn't like that there's a big sidebar taking up screen real estate nor the idea of sticky-notes living on layers on top of - and often obscuring - the original page. We think these characteristics have kind of helped give annotation a bit of a bad name and limited more casual adoption and traction.

    We decided to make a tool that strips away the things we didn't like about existing services. To do this, we've worked on technology that allows the user to enhance pages in-line. The user's content lives as a native part of the page, not 'out-of-line' in a side bar or non-native content layer. We think that gives a different level of control and power to the user, gives a different value to their content, and rids us of the heavyweight UI elements of previous services in one swoop! We let people share their enhancements with you can follow people of interest, and their enhancements get merged into your view of the web. We are still in pre-start up mode but you can view the concept for yourself at [Broken Link Removed]
    thanks for your time.

    I have found one nice tool Is so clean and user-friendly, that I'm surprised why more web searching services are not using that solution. Do you have any idea?

    Protonotes just relaunched as a cross browser service that you can install on your website with a few lines of JavaScript, afterwhich anyone who visits your website can then add notes - no plugins to install or bookmarklets to use.

    there is a totally new version of Fleck available. You can still leave notes on webpages, but the main focus is on sharing interesting links within teams, small companies and with friends. A lot more useful.

    Another one to try is - it lets you annotate uploaded PDF and Word documents (sample) as well as snapshots of web pages. Highlight text to create a note, notes can be shown as draggable boxes, in the right margin or as footnotes. Notes and highlighted terms are used to build up a searchable index, with page previews, and each note can also have replies and tags for workflow / reviews. The focus is on discussing and indexing documents and web pages online with colleagues.

    I've tried all these services/apps and, as usual, find that what I really need is a way to mash them up. Each has features I like, but all lack at least one essential feature that others have.

    Diigo has the best feature set for me. You can highlight text (or anything) on a page, and make a stickynote associated with that highlight. The note isn't visible to readers until they place the cursor on the highlight, then a window pops up with the note in it. This means that the flow of the article isn't interrupted by inline notes, and none of the text is obscured. Once you're done highlighting, you can save and email the url of the highlighted page to anybody. By clicking on the link in the email, the recipient is taken to the marked-up page and can read the notes by running the cursor over the highlights. All this is great except that it doesn't work with dynamically-generated pages, which more and more pages are.

    Fleck is my second favorite. It seems simpler and less buggy than Diigo, and it hides comments in in numbered footnote markers. Clicking on the marker opens it and lets you read the note. Unfortunately, Fleck doesn't support highlighting, so one has to guess exactly what the note refers to. I use annotation for editorial markup, so I want to, for example, comment on a phrase inside a sentence. With Fleck, the reader can't be certain just which words are involved. And, as far as I know, dynamic pages don't work here, either.

    SharedCopy does allow highlighting and should work with dynamic pages but, while it does allow you to reduce the size of the note somewhat, the text box is still big enough to obscure part of the text, especially if the comment is a long one. This could maybe be overcome by the fact that it lets you draw lines, so you could draw a line from the highlighted portion to a text box tucked somewhere out of the way. Problem is, the line is so faint as to be almost invisible, so that really doesn't work, either. This would be an excellent choice for me if they would only make the text box reduce to a point, as in Fleck, or only pop up when the highlight is selected, as in Diigo.

    JumpKnowledge highlights your comments and puts them inline, like Google Docs. They think this is a virtue because none of the text is obscured, but I find that an editorial comment inserted into the middle of a sentence totally disrupts reading. Again, it works with dynamic pages, and would be great if only one of the previously mentioned techniques for hiding notes was employed.

    Stickis and Mystickis both just place stickynotes wherever you want them, and don't offer the precision I need. TrailFire is almost in a different category from all the others, allowing, as I understand it, only one comment per page, so not really for making detailed comments on portions of pages. Draw Here is available only to other members, so you can't email pages, and your markups can be overwritten. ShiftSpace is a horse of a different color, too. I'm not sure I really understand it, but it looks like a given website can be annotated only if it has ShiftSpace on the server. It has some cool features, like the (experimental) ability to swap site content, but seems to require a higher a higher level of geekism than I can manage.

    Other people want to use these applications in very different ways than I do, so I'm not suggesting I don't like wouldn't be good for somebody else. They're all pretty nifty, actually.

      I'm glad I'm not the only one seeing problems with Diigo. When I first started using their service I gladly abandoned Delicious. Now, I'm noticing that most of my annotations no longer work.

      I had a suspicion that this was partly because of the dynamic pages.
