The problem it solves

You want an AI assistant for personal or business tasks, but sending that conversation through mainstream messaging apps feels exposed. You want something more private without giving up the convenience of chatting from your phone.

Who it fits

Privacy-conscious individuals or small teams who want an AI assistant without routing conversations through mainstream messaging platforms.

How it works

  1. You send a message to your Signal number
  2. The system passes your message to an AI assistant
  3. The AI thinks through your request, using extra reasoning steps if needed
  4. It remembers recent messages to keep context in the conversation
  5. The reply is sent back to you in Signal
What you get

A private assistant only you can reach

You get a personal AI assistant you can message anytime through Signal's encrypted chat, wherever you are.

What you get

A private, encrypted chat conversation with your own AI assistant.

What you need

A Signal account, a self-hosted server, and an OpenAI account.

We can build this. But should you?

The hard question is not how to build it. It is whether this is the right thing to build first.

That is what a Fractional Chief AI Officer figures out with you, before anyone writes a line of code.
