The short version of how Telbox works — pricing, privacy, platforms, and the developer platform. Still stuck? Contact support.
Getting started
What is Telbox?
Telbox is a voice-first messenger that remembers. Send a voice note and you get the summary, the tasks, and the answer — and you can ask your own history anything. Underneath, it's voice + AI privacy infrastructure: every message and call is end-to-end encrypted, and AI is on from the start but always in your hands — turn it off per conversation or entirely, anytime.
Is Telbox free?
Yes — Telbox is free at launch, and there's nothing to buy yet. The Free plan gives you unlimited encrypted messaging and calls, voice notes with transcription, and a monthly AI quota. Paid tiers are coming soon: Plus (planned $6.99/mo) will lift the AI limits and Pro will unlock your cloned voice.
What platforms is it on?
iPhone and iPad first (in TestFlight now, App Store coming soon), Android in active beta, and native desktop + web on the roadmap. Read-sync across your devices is built in. Get the app →
How is Telbox different from WhatsApp, Telegram, or Signal?
Telbox is built around your voice — notes become summaries, tasks, and a searchable memory no other messenger gives you. And it's built for AI agents that run as cryptographically verified participants inside the encrypted chat. See the features →
Privacy & security
Is it really end-to-end encrypted?
Yes. Messages use Envelope v1 (X25519 + AES-256-GCM + Ed25519) and calls add a forward-secret key exchange with per-frame encryption. The server stores only ciphertext — never your messages in the clear. When you use AI, content is decrypted only for that processing, on a no-train endpoint; turn AI off and nothing is decrypted server-side. How it works →
Does Telbox train AI on my messages?
No. When you use AI, your content goes to an endpoint that is contractually bound never to train on it — on every tier, free included. Turn AI off and nothing leaves the encrypted envelope at all. Encrypted transport, AI on your terms.
What does "AI on your terms" mean?
Transport is always end-to-end encrypted. The only choice is whether AI processes your content to summarize or answer — and that's your switch, per conversation and per group. AI off = pure E2E. AI on = no-train understanding.
What are verified agents?
Every Telbox agent has its own cryptographic identity. Its messages are signed and verified on your device, so a "verified" badge is a proof, not a label anyone can fake. Revoke an agent and every message it ever sent loses its badge, retroactively.
Developers & the API
Does Telbox have an API?
Yes — a developer platform, currently in preview. Build AI agents that run as verified participants, send messages and voice notes, read and summarize threads, and reach the world through MCP both directions. Explore the platform →
Where are the docs and SDKs?
Full documentation lives at docs.telbox.ai, with first-class Python (
pip install telbox) and TypeScript (npm i @telbox/sdk) clients generated from the same OpenAPI spec. Self-serve keys land with the preview — request early access →.How do I build an agent?
Describe what you want in plain language — the
@build compiler turns it into a typed, validated agent you can preview and create. Or start from one of 10 templates. Every agent begins draft-only; you grant authority per capability with hard limits.Can my agent be called from other AI tools?
Yes. Telbox speaks the Model Context Protocol both directions: your agent can consume external MCP servers, and every published agent is itself an OAuth-gated MCP endpoint callable from any MCP-compatible client.
Plans & business
What's the difference between the plans?
Free covers encrypted messaging, calls, and a monthly AI quota. Plus unlocks unlimited AI & memory, voice signing, and 30-minute notes. Pro adds voice cloning, real-time call translation, and calendar sync with an email bridge. Business adds SSO/SCIM, audit logs, legal hold, and retention. See pricing →
What is Telbox for Business?
Two products: the Voice Workforce ($99/seat/mo) — team-wide voice memory you can search — and the Voice Cloud API for embedding Telbox's verified voice + AI in your own product. Learn more →
What is a Private Space?
Your own private Telbox for a family, team, or community — everyone in the space gets everything in Plus, plus no-training AI for the whole circle with no monthly limits, run by you. 5 seats are included; add more at $12/seat. Coming soon — planned $99/mo, billed on the web. See pricing →
What is a Sovereign Cell?
A self-hosted deployment for banks and institutions, designed so data stays in your cloud and Telbox acts as a trust broker rather than a data processor. Customer-managed key custody (your KMS) is on the roadmap. Details →
Where is Telbox based?
Telbox is operated by Telbox AI Labs LTD, registered in England and Wales, United Kingdom, with English and Arabic support today.
