Share as little as you like.

Augustus doesn't send your contracts or other data anywhere except to your chosen AI provider. You pay for API calls at the normal rates charged by your provider. If you prefer, you can configure Augustus to run free, open AI models entirely locally on your Mac.

Augustus is currently pre-alpha software and is offered as-is for evaluation purposes only. Pre-alpha users will receive updates at no charge until a full-point release is made available. Augustus is obviously not a lawyer and can't provide legal advice. Neither Augustus, Zenzen Labs, nor Sol Irvine is your lawyer.
