If you're looking for a free alternative, Genius has a web annotator service [0], available either through their site or self-hosted. Registration is required to make annotations, though.<p>[0]: <a href="https://genius.com/web-annotator" rel="nofollow">https://genius.com/web-annotator</a>
This is a really cool idea!<p>However, I don't think this works very well on websites where you have to interact to get to other pages.<p>I just went to Google, searched something, and left a comment on one of the results, but I couldn't view the comment afterwards.<p>I can imagine many websites that this could be a problem for, such as an authenticated experience or a wizard where the step isn't captured in the URL explicitly.<p>But I'll keep this in mind for getting feedback on static pages for sure!
Very cool! Almost like Mixpanel in that any event can be caught, only this is for tagging notes on sites. Well done, it looks very promising. Does it work on full JS Single Page Applications?
