Telegram Bridge

Private AI for Telegram — Hardware-Sealed Bridge

A private ChatGPT alternative inside the messenger your team already uses, all day. Same models as the web app, same hardware sealing, same DPA — just delivered as a Telegram bot you can add to a personal chat or a group. The standard ChatGPT-style Telegram bots proxy to OpenAI; this one terminates inside an Intel TDX enclave inside the EU.

Why Telegram specifically

Telegram is the daily messenger for many European consultants, lawyers, accountants, and engineers. Putting a private AI inside the same surface removes friction. There is no new tab. No separate login. No context switch. You just message the bot the way you would message a colleague.

The problem with the existing ChatGPT-style Telegram bots is structural: they are convenience wrappers around the OpenAI API. The moment a client name, a contract clause, or a sensitive document fragment goes into the chat, it ends up on US-controlled infrastructure where the operator and US authorities (FISA 702, CLOUD Act) retain technical access. The bot operator's privacy policy does not change that — they are a passthrough.

How the bridge works

The four steps of a sealed conversation
  • 1Telegram client → bridgeYour message reaches the VoltageGPU bot endpoint over Telegram's standard transport encryption.
  • 2Bridge → enclaveThe bridge immediately forwards the message over TLS to the inference endpoint, which runs inside an Intel TDX enclave. There is no plaintext store at the bridge layer.
  • 3Sealed inferencePrompts are decrypted only inside the protected memory region. The host operating system cannot read them. Remote attestation produces a cryptographic proof per session.
  • 4Response → TelegramThe model response goes back the same way. The bridge does not log message contents. The dashboard shows the attestation hash for each session.

Three use cases that come up most often

Solo professional
  • Lawyer or consultant who lives inside Telegram for client coordination
  • Wants a private ChatGPT alternative without leaving the messenger
  • Plus plan at $20/month, hardware-sealed Qwen3.5-397B-TEE
Small team in a Telegram group
  • Add the bot to an existing group, mention it to ask questions
  • Each user keeps their own session, attestation per request
  • Starter plan at $349/month for 3 seats
Regulated-sector users
  • Cannot put client data into bots that proxy to OpenAI
  • Need EU controller, hardware sealing, DPA per RGPD Article 28
  • Pro at $1,199/mo or Enterprise at $3,499/mo with SSO/SCIM

Pricing — the bridge is included on every paid plan

The Telegram bridge is not a separate product. It is the same inference endpoint as the web app and the OpenAI-compatible API, with a Telegram-specific surface. The bridge is included on every paid plan, and the free tier gives you five real requests per day inside Telegram so you can validate the workflow before any commitment.

Plus

$20/month — solo

Six questions that come up

How does the Telegram bridge work technically?

You start a chat with the VoltageGPU bot on Telegram. The bot relays your messages over a TLS connection to the inference endpoint, which runs inside an Intel TDX enclave. Prompts are decrypted only inside the protected memory region. The model response goes back the same way. The bot keeps no copy of the conversation outside the encrypted channel.

Can Telegram or its hosts read the contents?

Telegram itself sees the encrypted transport between your client and Telegram's servers. The bot endpoint receives the message, immediately forwards it to the TDX enclave over TLS, and returns the response. The two sensitive points — bridge handoff and inference — are both inside the EU, and the inference itself is hardware-sealed.

Is this just a wrapper around the OpenAI API?

No. The bridge is connected to VoltageGPU's own inference, not to OpenAI. The models are Qwen3.5-397B-TEE on Plus and Starter, and DeepSeek-R1-TEE on Pro and Enterprise. Both run inside Intel TDX enclaves on EU infrastructure. There is no path from your Telegram message to the OpenAI API.

Who is this useful for?

Three groups: (1) consultants and lawyers who want a private ChatGPT alternative inside the messenger they already use; (2) small teams that want a shared AI assistant inside an existing Telegram group; (3) regulated-sector users who cannot put client data into the standard ChatGPT Telegram bots that proxy to OpenAI.

How does pricing work for the Telegram bridge?

The bridge is included on every paid plan: $20/month Plus for solo, $349/month Starter for three seats, $1,199/month Pro for ten seats, $3,499/month Enterprise with SSO/SCIM and DeepSeek-R1-TEE. The free tier offers five real requests per day inside Telegram.

Can I revoke a Telegram session?

Yes. From the dashboard you can revoke any active Telegram link, which invalidates the bridge token and closes the bot session. New messages from that Telegram account will be rejected. On Enterprise plans, the admin can revoke any user's Telegram link from the SSO console.

Security for Sensitive Data — Full Technical Details

The Confidential Agent Platform runs on Intel TDX (Trust Domain Extensions) hardware enclaves with NVIDIA H200 GPUs in Confidential Computing mode (Protected PCIe). The security stack: (1) Intel TDX encrypts RAM with hardware-fused CPU keys — the hypervisor is OUTSIDE the trust boundary and physically cannot access TD memory. (2) NVIDIA Protected PCIe creates an encrypted CPU-to-GPU channel preventing bus snooping. (3) LUKS encrypted filesystem — decryption key released ONLY after successful remote attestation. (4) Remote attestation: Intel TD Quote (signed by CPU-fused private key) verified against Intel public keys plus NVIDIA GPU attestation plus proof of VRAM work. Only PERFECT measurement matches pass. (5) Post-quantum end-to-end encryption for prompts and responses. (6) Model verification cryptographically proves every output token came from the declared TEE model, defeating model substitution attacks. (7) Continuous monitoring with random integrity challenges and immediate node removal on failure. Real-time public attestation reports available. This is not software security — it is silicon-level isolation verified by Intel and NVIDIA hardware attestation. EU company (France), GDPR Art. 25, Intel TDX hardware attestation.

Not Limited to 8 Templates — Connect Your Own Agent

The 8 templates are starting points. Any OpenAI-compatible agent works: OpenClaw (247K+ GitHub stars), CrewAI (50K+), LangChain (100K+), or any custom agent. Change one line (base_url) and every LLM call runs inside a TDX enclave. The platform is an API, not a closed system.

Model Quality — Not Just LLM Output

Three model tiers: Starter uses Qwen3-32B-TEE (32B params, 40K ctx), Pro uses Qwen3.5-397B-TEE (397B MoE, 256K ctx — can ingest entire contracts), Enterprise uses DeepSeek-R1-TEE (reasoning model with chain-of-thought for CFA-grade analysis). The key differentiator is the TOOLS, not just the model. Tools are deterministic server-side code: the clause checklist runs exact IACCM/ABA rules, the risk score uses a fixed formula (critical x25, high x15, medium x8), the market benchmark compares against 12 real 2024-2026 deal data points. The LLM orchestrates which tools to use, but the tools produce exact, verifiable results. Model verification (cllmv) cryptographically proves every output token came from the declared TEE model.

Performance — No TDX Overhead in Practice

Intel TDX adds 3-7% overhead theoretically. In practice, VoltageGPU uses 8x NVIDIA H200 140GB (top-tier GPU) which more than compensates. Analysis completes in approximately 6 seconds. The warm-tdx system keeps enclaves pre-heated — zero cold start for subscribers. Per-second billing means you only pay for actual compute time.
