About Weyvox
Weyvox is a personal AI agent that makes and answers phone calls, handles chats and sees errands through — together with a messenger, free calls between users and real phone numbers. This page is about the people and the principles behind it. For what the product does in detail, see the documentation.
Who we are
Weyvox is an independent AI company of a new kind. The product is created and developed by one person — the founder — together with autonomous AI agents that take on the daily routine of development and support. The same technology that works inside the app also builds Weyvox itself.
The founder
Built Weyvox out of the conviction that a personal AI assistant should not just reply in a chat, but actually get things done — call, negotiate and see an errand through to the end.
The problem we solve
Phone errands eat time and energy: booking an appointment, sorting out a bill, waiting for an operator to answer, trying not to forget anything after the call. Weyvox takes this off your shoulders: you say what you need — the agent calls, negotiates, waits on the line instead of you and comes back with the result and a note.
The agent
The chat with the agent is an integral part of the app. It is a conversation with Claude by Anthropic: you choose the model (Haiku, Sonnet, Opus or Fable) and its reasoning effort. In the chat the agent has access to the app's features — personal matters, memory, tasks and calls — and works exclusively in your interest.
The agent always introduces itself as an AI at the start of every call. This is a built-in rule that cannot be switched off — required of voice agents calling consumers in the EU under the AI Act from 2 August 2026, and applied everywhere by default.
Documents
The agent produces real documents, not just answers. Ask it for an invoice, an act, a certificate, a report or a one-off contract and it hands you a finished PDF right in the chat. Five built-in templates hold your business details — name, tax and VAT numbers, address, bank details, signatory — so every document carries them without you repeating anything, and the app issues the next number in your own series rather than inventing one. You can add templates of your own. Documents are rendered on your phone.
Security and privacy
Personal chats in Weyvox are end-to-end encrypted: texts, photos, videos, files, voice messages and locations are encrypted on your phone, and only the participants' devices hold the keys. On our servers your correspondence exists only as ciphertext we cannot read — which also means we are physically unable to hand it over to anyone.
The agent reads a personal chat only when you open it inside that conversation, and sees only what your device decrypted; it has no server-side access to your correspondence. Every one of the agent's permissions — chats, contacts, personal matters, location — stays in your hands. No ads and no trackers.
The full model, including what is deliberately not end-to-end encrypted and why, is set out in the Privacy Policy and in the documentation.
Our philosophy
Technology should work for people. Core communication in Weyvox is free; paid features are billed by actual use, and every paid action is visible in your usage history. There are no subscriptions — see pricing for the rates.
