Tabcom

Tabcom turns any webpage into a shared space where your team can talk, point, and mark things up together — without ever leaving the page. Install Tabcom and open any tab with your teammates. You'll see each other's live cursors moving across the page in real time, and you can drop pins, draw areas, and leave sticky notes directly on content — a design mockup, a spec doc, a dashboard — instead of describing "the third paragraph" over Slack. Hit / to leave a quick ephemeral note, or @ to pin a comment that stays until someone resolves it. When a conversation needs more than text, jump straight into a 1:1 voice or video call without switching apps. What you get: Live cursors — see exactly where teammates are looking on the page, right now Pins & areas — annotate any element on any site, with threaded discussion attached to it Quick notes — / for a fleeting comment, @ for one that sticks Voice & video calling — built in, one click away Communities — organize people and conversations around the pages and projects you actually work on Guest access — join a conversation instantly with no account, or create a free account for a session that never expires Tabcom is invite-only while we're in early access — if you don't have an invite code yet, you can still explore instantly as a guest.
