Turn the entire web into a conversation
Annotier lets you comment on any website, highlight what matters, and join discussions right where the content lives — on desktop with the extension and on mobile with the app.
What is Annotier?
The web wasn’t built for real conversations — comment sections are often missing, limited, or closed. Annotier changes that by making every page a place to talk.
If it has a URL, it can host a conversation. Share perspectives, add context, and discover what others think — without waiting for a site to enable comments.
- Comment anywhere — articles, videos, PDFs, product pages
- Bring the conversation with you: extension, app, or embed
- One identity across the web for consistent discussions
How it works
- Install the extension for Chrome or Firefox.
- Sign in once — Annotier lives in a tidy sidebar.
- Annotate and join conversations as you browse.
Want the full details? See the Extension Guide.
- Install the Annotier app from Google Play.
- Share any app content or URL from your browser into Annotier.
- Read, post, and follow threads on the go.

Why Annotier?
We believe open discussion is a cornerstone of a free web. Diverse viewpoints help everyone form deeper, more informed opinions. Annotier provides a universal, consistent way to talk about content, even when native comments are missing or closed.
Conversations aren’t locked to any one website’s rules or whims. Participate on your terms.
A single identity across the entire internet, so you can follow topics — not platforms.
