Are there Web applications for annotating webpages for free?

I would like to underline, highlight, and add notes to a webpage I am browsing in my browser (Firefox).

Whether the annotations can be saved or not are both fine, although being saved is better.

I am using Diigo, but it only offers 1000 highlights per year for free.

  • Do you want annotations to be stored online or offline?

  • I would like to know both online and offline. I hope it will not consume too much CPU and RAM of my laptop.

  • I'm looking for the same thing! Thank you for your question. I want also a replacement for Diigo, way too expensive. The Diigo caching page, the highlighting and annotation tool seems hard to imitate it seems.

  • And hosting your own content, are you interested in this possibility?

I can recommend two:

Awesome Screenshot Plus


It's essentially a screenshot app that allows you to annotate those screenshots, draw on them and then save those.



Highlight, color, bold, underline, italicize and strikethrough text to flag critical passages and parts of a web page. Also allows you too save pages.

    Does scribble save annotated webpages on my computer or their online server?

  • I think it's online only. At least it doesn't say on the site that offline saving is supported, but it could be a feature.
