Your Data.
Your Rules.

I don't want your data. Period. No telemetry, no analytics, and your requests are never sent to our servers.

Private
Inference.

There is no telemetry or analytics in Synth. The AI models run 100% locally. It doesn't send your prompts to any servers. It's entirely you and your local hardware.

Being an indie project with no investors means there's no business model built on your data. No data, no leaks, no compromises.

Local
Encryption.

When you choose to save conversations, they are stored directly on your hard drive and encrypted with 256-bit AES. Your chats never leave your machine — not even in ciphertext over a network.

The encryption key is derived from a passphrase you set. Not stored anywhere. Not recoverable by anyone but you.
