Frequently asked questions

Is MarkLayer a free AnnotateWeb alternative?

Yes. Both are free with no sign-up. MarkLayer adds threaded comments, multi-page projects, 90-day retention (vs AnnotateWeb's 2-minute cleanup), and is open source. AnnotateWeb wins on multi-language UI and not requiring a Chrome extension.

Why would someone leave AnnotateWeb?

Common reasons: 2-minute inactivity deletion is too short for real review cycles, lack of threaded comments, no multi-page projects, or wanting a Chrome Web Store-distributed extension instead of a bookmarklet.

Are these tools open source?

MarkLayer and Hypothesis are open source. Markup.io, Pastel, Ruttl, and AnnotateWeb itself are closed-source.

Which is the closest match to AnnotateWeb's bookmarklet model?

AnnotateWeb's bookmarklet model is unusual. Most alternatives are either Chrome extensions (MarkLayer, Hypothesis) or web apps (Markup.io, Pastel, Ruttl). If extension-free is non-negotiable, AnnotateWeb stays the strongest fit.
