Pulse DocsReal-time collaboration for your website

Comments pinned to pixels, live cursors, presence, and shared data — self-hosted, added with a single HTML tag.

📌

Comments Pinned to Pixels

Users pin threads anywhere on the page. Barycentric multi-landmark anchoring keeps pins in place across reflows, redesigns, and screen sizes — and creators can drag their pins to move them.

💬

Threads, Mentions, Reactions

Replies, @mentions with autocomplete, emoji reactions, edit and delete with confirmation, resolve when done.

🎮

Live Cursors & Presence

Color-coded cursors, click ripples, who's-online avatars, follow mode, and typing indicators — all in real time.

🔔

Notifications That Navigate

Mentions, replies, and reactions land in an inbox. Clicking one scrolls to the pin and opens the thread.

🎤

Media Notes

Attach images, in-browser voice notes, and video clips to any comment. Lightbox and inline players included.

🚀

One Line of HTML

Drop in a single tag. Works with any stack — script tag, npm, React, Vue, Svelte, plain HTML.

🎨

Fully Themeable

CSS custom properties for every surface, including real dark mode. Headers, glass, accents — all tokens.

⚡

P2P Shared Data

Optional CRDT-backed SharedMap, SharedList, and SharedCounter sync peer-to-peer over WebRTC with server persistence for late joiners.
