03 web chat
CallChat-owned login surface
The web chat shell at /chat/ gives users a CallChat-branded room, Shield, Zero Bot, and invite surface.
The live web client at /element/ provides Matrix login, rooms, files, and calls through the active CallChat homeserver.
04 shield
CallChat Shield / ZMath
Shield is the ZMath layer for protected files, attachments, and vault notes. On callchat.org, the hosted Shield experience is included for active accounts and is designed to manage vault material automatically for normal protected-file actions.
Other servers need a paid ZMath license to enable the proprietary Shield policy layer. ZMath / Zero Boundary Algebra provides the research and policy layer behind Shield while the public website avoids exposing protected implementation details.
05 q-calls
Secure calls with a serious quantum-ready path
CallChat Q-Calls keep live calling on Matrix/Element WebRTC, DTLS-SRTP, device identity, and the configured TURN relay. The Q-Call layer adds Shield policy, PQC-ready planning, call setup evidence, and optional server-side IonQ research hooks.
IonQ keys and experimental code are never placed in public JavaScript. CallChat does not claim live audio is quantum encrypted today.
06 zero bot
Optional AI helper
Zero Bot is the optional assistant path for @zero:callchat.org. It is designed for consent-based room help and clear AI-generated output.
Example commands include !zero help, !zero summary, !zero decisions, !zero tasks, !zero explain-shield, and !zero server-status.
