Your data belongs to you and your clients.
Glaucon is built on that very principle. Our philosophy holds that AI should empower human autonomy and push the boundaries of what ought-to-be. But this does not mean you must compromise your values. Your ideas, your obligations, and your dignity are not mere commodities; they are yours to keep. Glaucon is here to protect you and your contracts in a way that nearly every technology company refuses to.
The best models, without becoming the product.
Free chatbots are paid for with your conversations. Glaucon gives you the same frontier models, paid for honestly, owned by you.

Own everything
Your history is encrypted under your key, on your terms. Export it or erase it — delete means delete.
Share nothing
Cyfr masks the names you declare before anything leaves your device. The people in your life stay out of it.
Questions worth asking.
Can Glaucon read my chats?
No. Saved history is ciphertext under your passkey. Live analysis decrypts only inside an attested secure enclave — not on the servers that route it.
Is my data used to train AI?
No. Requests route through zero-data-retention providers that do not store or train on them.
What happens when I delete something?
It is gone. History exists only as ciphertext under your key — there is no plaintext copy anywhere to linger.
Why not just use a consumer chatbot?
Consumer chatbots can retain conversations, train on them, and tie them to your identity. Glaucon is built the opposite way: zero retention, end-to-end encryption, and keys that stay with you.
Is it free to start?
Yes. Start free with no card. Add one-time credit or a plan only if you need more.
Which AI models do I get?
Auto routing or your pick of frontier models. The selector is visible before you send, so the choice stays with you.
