A note before we talk

Joe is an AI guide. Audio and messages are processed by OpenAI so Joe can respond. Don’t share passwords, personal records, or confidential business information.

You choose how to join in. Voice requires your microphone permission; you can mute or end it at any time. Typing does not need microphone access.

We use a 30-day usage cookie and hashed network identifiers to enforce limits. The site does not save your conversation history; recent conversations stay only in this browser tab and clear when you close it.

If you sign in, AWS Cognito handles your account and we store a hashed, expiring session identifier in PostgreSQL. CISO Joe uses email codes or your chosen identity provider; no password is created or stored by this website.

Usage limits apply to this public service. Joe can help you explore ideas, but check important decisions with the right people for your organization.
