Private by Hardware

How Trusted Execution Environments (TEE) make "zero logging" actually mean something.

TEE ensures your prompts stay private not because we promise—but because it's technically impossible for anyone to see them, even us.

The Problem with Trust

When you use most AI services, you're trusting that the provider won't read your prompts, log your data, or train on your inputs. But trust isn't verification. Companies change policies, get acquired, or face legal pressure.

Kulpa is different. We're building toward cryptographically verifiable privacy—where the hardware itself enforces your privacy, not our policies.

What is a TEE?

A Trusted Execution Environment is a secure, isolated area within a processor. Think of it as a locked vault inside the CPU where code runs and data lives—completely invisible to everything outside, including the operating system, cloud provider, and even administrators with physical server access.

Key Benefits

🔐 Complete Privacy

Your prompts and generated images are encrypted from your device to the TEE. No one in between can see them.

✓ Cryptographic Proof

Each computation generates mathematical proof that it ran in a genuine, unmodified TEE—independently verifiable.

⚡ Real Performance

Modern TEEs add less than 1% latency overhead. Privacy doesn't mean slow.

🛡️ Zero Trust Required

You don't need to trust us, the cloud, or anyone. Hardware enforces privacy.

The Technology

Intel TDX Trust Domain Extensions create confidential virtual machines that isolate AI workloads from the host system entirely.
NVIDIA TEE GPU-level isolation protects model weights and inference computation. Your prompts never leave the secure enclave.
Attestation Cryptographic chain from open-source code to hardware execution proves the TEE is genuine and uncompromised.
End-to-End TLS terminates inside the TEE—not at load balancers. Your data stays encrypted until it reaches the vault.

Kulpa's Roadmap

Today, Kulpa operates with a "zero logging" architecture—we don't store prompts or generated images on our servers. But we know promises aren't proof.

We're actively working to deploy TEE-based private inference, partnering with providers like NEAR AI who offer hardware-verified privacy. When complete, you'll be able to verify cryptographically that your wildest prompts stayed completely private.
