The Private Alternative
to ChatGPT
Powerful AI models. Completely different approach to your data. ChatLock gives you access to leading AI models while keeping every conversation end-to-end encrypted and provably private.
Why people are switching
from ChatGPT
ChatGPT is a great tool, but it comes with trade-offs that matter for sensitive work.
Your data trains their models
ChatGPT uses your conversations to improve its models by default. Your prompts, code snippets, and confidential data become part of their training pipeline.
No end-to-end encryption
ChatGPT conversations are stored on OpenAI servers in plaintext. Employees and systems can access your chat history.
No control over your history
Even if you delete conversations, OpenAI retains data for up to 30 days. You have no cryptographic guarantee that your data is truly gone.
What makes ChatLock different
We built ChatLock from the ground up for privacy, without sacrificing the AI experience you expect.
Confidential AI inference
AI models run inside hardware-secured enclaves. Your data is encrypted in memory and inaccessible to anyone, even us, verified by cryptographic attestation.
End-to-end encrypted history
Your chat history is encrypted with a key only you hold. It stays on your device by default. Not even ChatLock can read it.
Open-source AI models
Choose from leading open-source models like DeepSeek, Qwen, and more. All running inside the same secure enclaves with full privacy guarantees.
Provable zero data retention
We don't just promise privacy, we prove it. Cryptographic attestation verifies that your data was processed in isolation and never stored.
