The Private and European
Alternative to ChatGPT
Why people are leaving ChatGPT
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
European data sovereignty
Need your data to stay in Europe? Run your conversations through an EU-based, GDPR-compliant provider. Every prompt is processed inside the European Union, under European data protection law.
GDPR compliant
Built to the EU's data protection standard. You keep full rights to access, export, and delete your data, and your conversations are never used to train models.
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.
Your data stays under your control,
with the power and flexibility of the cloud
