End-to-end encrypted messaging
Messages, files and calls are encrypted on the device before they leave. Sembl never holds the keys, so we can't read your messages — and neither can anyone else.
Sembl is the chat product for organisations that take privacy seriously. Direct messages, group chats, channels, audio and video calls, multi-device and bots — all included.
Messages, files and calls are encrypted on the device before they leave. Sembl never holds the keys, so we can't read your messages — and neither can anyone else.
Run org-wide announcements, team channels, and private working groups from the same product. Discover channels by directory, or lock them down to named members only.
One-on-ones and small group threads with the same encryption guarantees. Threaded replies, rich text, files and media. No "basic plan vs business plan" feature gates.
Audio and video calls with screen share and in-call status, built into every chat. Works inside the app and in the browser — no separate meeting tool to install.
Sembl ships with bot support on day one. Wire bots into channels, group chats or DMs to push alerts, run approvals, kick off workflows and bridge to the rest of your stack. Included in every plan — see the Bots page for the full picture.
Pair a phone, tablet, laptop or desktop in seconds with a QR code. Messages stay in sync across devices, and revoking a device is a single tap.
Sembl is built around organisations from the ground up. Tenants, teams, roles and privileges are first-class — not a bolt-on for enterprise customers.
Share files, images, audio notes and live location inside any chat. Everything ends up encrypted on the wire and tied to the same retention rules as messages.
Whether you're 10 people or 10,000, Sembl is built for organisations where conversations have to stay private and infrastructure has to be boring.
Subscribing takes minutes. You'll get a Sembl workspace and an admin seat to invite your team.
