No logins. Zero fuss. Start collaborating in seconds.

Available on all your devices

Loci is web-first and you can doodle across all your mobile and desktop devices1 without bloated installs. And, it works perfectly with your stylus too — we've built in palm rejection, pressure sensitivity, and more!2

Built for real-time collaboration

No laggy syncing, no editing conflicts, and no whiteboard manhunts! Strokes are rendered as they are drawn, and you can track other users' screens automatically, even across breakout whiteboards.

Create lasting memories together

Showcase your creativity on the infinite canvas with friends and family through doodle sessions, DnD campaigns, and more! There are even built-in templates for you to get started right away.
