Is Tweak an AnnotateWeb alternative?

AnnotateWeb is free without sign-up. Tweak is a commercial product with threaded comments, multi-page reviews, hosted persistence, and Free + Pro plans. AnnotateWeb wins on multi-language UI and not requiring a Chrome extension.

Why does Tweak use a Chrome extension instead of a bookmarklet?

A Chrome extension gives your team persistent review state, threaded comments, and a richer toolbar on the live DOM. Bookmarklets are constrained by what JavaScript can be injected into a single page.

Does Tweak support multiple languages like AnnotateWeb?

Currently Tweak is English-only. AnnotateWeb supports 8 languages. If you need a non-English interface today, AnnotateWeb is a better fit.

How long do Tweak share links last vs AnnotateWeb?

Tweak share links last 90 days from last access. AnnotateWeb sessions delete after 2 minutes of inactivity. If you need annotations that survive a sleep cycle, Tweak is the right tool.

Is Tweak open source?

No. Tweak is proprietary software operated at tweak.page. Contact legal@tweak.page for licensing questions.

Tweak vs AnnotateWeb

You want a commercial hosted product with support@tweak.page and clear data handling.
