Show HN: Panda.chat – A ChatGPT alternative designed to protect your privacy

Good morning, HN folks!

I'd like to introduce you to https://Panda.chat — an end-to-end encrypted LLM designed to protect your privacy. It runs Deepseek R1 & Llama 4 Scout.

These days, we're asking ChatGPT for medical, legal, and mental advice. But some AI services aren't designed to protect our privacy. Rather, they're designed to log your inputs & train the model for better performance.

We built https://Panda.chat to solve this.

Panda runs AI models in Trusted Execution Environment (TEE) inside of the GPU, enabling end-to-end encryption from your device to TEE. So no one—including us—can see your input/response. We can also prove your conversation was fully protected with a code hash posted on Ethereum.

Try http://panda.chat today! Enjoy the fully end-to-end encrypted LLM experiences. Would love to get your feedback on this :)
