CallChat ZERO is a Matrix-compatible sovereign messenger using callchat.org as the public front door and active homeserver.
Yes. Open the hosted CallChat web client or install Element from official app stores or desktop downloads, choose a custom homeserver, and use callchat.org.
Use callchat.org. The separate matrix.callchat.org hostname is reserved for a later DNS/proxy step and is not needed for normal login today.
Yes. Standard Matrix-compatible secure messaging remains free.
Yes. CallChat-hosted Shield is included on callchat.org as the free showcase for active hosted accounts. Other servers need a paid ZMath license.
Yes. Calls are available through Element with active CallChat accounts on mobile and desktop.
Q-Calls are the secure-call option for CallChat. Live calls use Matrix/Element WebRTC, DTLS-SRTP, identity checks, and TURN relay support. The Q-Call layer adds Shield policy, PQC-ready planning, call setup evidence, and optional server-side IonQ research hooks.
No. IonQ belongs in a future server-side research or attestation hook. CallChat does not put IonQ keys in public JavaScript and does not claim live voice packets are quantum encrypted today.
CallChat Shield is the ZMath layer for protected files, attachments, vault notes, and Q Call posture. On callchat.org the hosted Shield experience is included; self-hosted buyers license it.
It is the CallChat research layer behind Shield behaviour and premium access design, wrapped around standard cryptographic controls and user-owned secrets.
No. In the hosted CallChat flow, the compatible CallChat app or module manages Shield vault material automatically for normal protected-file actions. Advanced export or recovery flows may still need clear user confirmation.
A .zme1 file is the CallChat Shield encrypted container for selected files or vault notes.
Element can download the .zme1 file, but premium Shield decryption requires compatible CallChat tooling. Normal chat stays usable.
Yes. CallChat is installable today as a web app from compatible mobile and desktop browsers. The downloads page also includes a Windows portable test app, Android and iOS build kits, desktop source, and SHA-256 checksums.
Use the installable web app now on Android, or download the Android TWA build kit if you want to build and sign an APK. A direct public APK button is shown only when a signed release file exists.
Zero Bot is the optional Matrix room agent path for approved rooms. The first live room is #zero-bot-lab:callchat.org, and the bridge is designed to use OpenZero as the local brain with local command-triggered speech.
Yes. The live bot can post command-triggered audio with !zero voice. Public rooms should not auto-speak every message, so voice stays deliberate and rate-limited.
The preferred route is local OpenZero on the same server or private network. Hosted AI can be added later only with clear admin configuration and consent.
Try !zero help, !zero callchat, !zero openzero, !zero frontdesk, !zero voice, !zero rules, and !zero status.
Yes. The live browser client is available at /element/ and the branded CallChat interface is available at /chat/.
It prepares an invite request. Matrix accounts are issued through controlled access.
CallChat uses controlled access and can add tokens, email verification, or reCAPTCHA for public registration.
Bot access is designed to be opt-in, consent-based, and no-memory by default.
callchat.org hosted Shield is included as the showcase. The paid secure-comms offer is the self-hosted ZMath Shield / Q Call license at USD $55/month or USD $550/year for unlimited users on one approved public server IP.
Yes. Use the Buy page at /license/#buy. Access is activated privately after payment confirmation and approval.
No. CallChat uses serious language around PQC-ready research and post-quantum envelope experiments.
Admins should not be treated as plaintext recovery agents. Automatic hosted Shield may offer controlled recovery/export paths later, but public support will not ask for raw Shield secrets.
CallChat uses access review and anti-abuse controls before issuing accounts.
Yes. Self-hosted ZMath licensing is available for licensed deployments while premium source remains protected.
