01 overview
What CallChat is
CallChat ZERO is a sovereign messenger built around Matrix compatibility. The public domain and active homeserver are callchat.org.
Users can start with the hosted web client or Element immediately. The dedicated matrix.callchat.org API hostname is reserved for a DNS update.
02 connect
How users connect
- Open CallChat Web or install Element. Use the hosted browser client, official app stores, desktop downloads, or the official Element website.
- Choose custom homeserver. Try
callchat.orgfirst. - Use
callchat.orgtoday. Enter it as the custom homeserver in Element. - Create an account. The CallChat sign-up form uses a local one-time arithmetic question and rate limits.
03 web chat
CallChat-owned login surface
The web chat shell at /chat/ gives users a CallChat-branded room, Shield, Zero Bot, and secure account-creation surface.
The live web client at /app/ provides Matrix login, rooms, files, and calls through the active CallChat homeserver.
04 shield
CallChat Shield / ZMath
Shield is the ZMath layer for protected messages, files, attachments, vault notes, and CallChat call policy. On callchat.org, the hosted Shield experience is included for active accounts and manages the protected room profile automatically for normal use.
Everyday workflow: sign in, verify a device if asked, open a conversation, and wait for Protected. You do not enter a passphrase, pattern image, profile reference, or room key for a new conversation.
New device: keep one trusted device online while the new device is verified and opens the same conversation. The protected profile is exchanged inside the Matrix-encrypted room. Older content still needs its original profile if no active device retains it.
Advanced options: automatic repair, legacy passphrase and pattern recovery, optional IonQ factor loading, Matrix-only mode, local reset, self-test, and diagnostic identifiers. These are support and recovery tools, not ordinary setup steps.
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 use owner-controlled MatrixRTC, self-hosted LiveKit, TURN, device identity, frame encryption, and a required room-scoped ZMath media factor.
An owner can generate a separate IonQ hardware-linked factor. The browser keeps its secret nonce local, combines it with validated job output, and makes the resulting factor a required input to the selected ZMath message, file, and call profiles.
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.

11 FAQ
Short answers
Can I use Element?
Yes, use the hosted browser client or official Element clients with a custom homeserver.
Can I use calls?
Yes, Element calls work with active CallChat accounts.
How does the IonQ option work?
The owner browser creates a secret nonce, sends only its SHA-256 commitment, and combines the validated hardware result locally into a separate factor. IonQ never receives the nonce or final factor. This is not quantum key distribution.
Can I install CallChat as an app?
Yes. Use the installable CallChat web app today on mobile and desktop, or open the downloads page for the Windows portable test app, Android/iOS build kits, desktop source, and checksums.
Is Shield required?
No, normal Matrix chat remains free; hosted Shield is included on callchat.org as the showcase.
Can AI providers read ZMath secrets?
No. Passphrases, patterns, Matrix keys, call factors, and protected-message or file plaintext are excluded from provider requests.
