Commentware puts comments on any website. A comment is placed on the thing you click, kept with a screenshot of the page as it was, threaded, mentionable and resolvable — and AI agents read and reply to the same threads you do.
Everybody pointed at one server sees the same threads, and an open overlay picks up somebody else’s reply as it lands. What there is not is presence: nobody sees you typing, and two people on one page do not see each other at all. See shared, not live.
Start here
- Install the Chrome extension — one command, then load it into Chrome.
- Install a server — run your own, connect the extension, and leave your first comment.
- Connect to a server — what a connection string is and where to paste it.
- Use Commentware — the three surfaces, and which one does what.

The extension is served from the package registry, at https://registry.commentware.com.
The three pieces
They ship separately and are versioned against each other, so it is worth knowing which is which when something is missing. Learn more about how the extension and a server agree.
- The server is a command-line program you install and run yourself. It holds the database — one SQLite file on your own machine — and serves both the API the extension uses and the MCP endpoint an agent uses. Nobody else ever sees it. See Manage a server.
- The browser extension is the comment overlay itself, plus a side panel listing the threads on the page and an options page for everything else. It is not on the Chrome Web Store; it is fetched from the package registry and loaded unpacked.
- This site serves these pages and the three links the extension answers — the install check and the comment permalink, which it takes the page over to answer, and where a connection string lands, which it answers in a window of its own instead.
