Core Architecture

Built for private communication, flexible workspace structure, and direct performance.

01 / ENCRYPTION

Signal Protocol & Messaging Layer Security (MLS)

One-on-one direct messages are encrypted with the Signal Protocol. Group conversations scale securely with Messaging Layer Security (MLS). All shared files, attachments, and chat backups are protected with client-side AES encryption. Decryption keys remain exclusively on your devices.

02 / STRUCTURE

Custom Channels & Arbitrary Roles

There are no locked, predefined roles like admin or moderator. You can define any role from scratch and attach any combination of permissions. Anything can be assigned to anyone.

03 / SEARCH

Local Inverted Index Search

Search message history across all channels in milliseconds. The search index is built and queried entirely on your local device without sending query terms to a server.

04 / PRIVACY

Zero Ads & No Telemetry

No third-party trackers, no behavioral advertising, and no algorithmic timeline manipulation. Communication is purely chronological.

05 / CALLING

Encrypted Voice & Video

Direct peer-to-peer audio and video calling with screen sharing built into direct chats and channels.
