1. AnnotateWeb — best free, no sign-up
AnnotateWeb is a free, browser-based tool for annotating any public webpage in real time. You paste a URL, draw and highlight with the toolbar, add text notes, and share a permanent link that works on any device — or export the page as a PNG. There is no account, no installation, and no paid tier. Sessions are private to people with the link, and annotations auto-delete after 2 minutes of inactivity. It's available in 8 languages.
Best for: quick, low-friction visual feedback on live public pages.
Trade-offs: built for public pages — sites with strict security policies or heavy JavaScript may render with limited functionality — and it doesn't include bug tracking, integrations, or a task board like the paid tools below.

Best for: students, educators, and researchers annotating sources.
