Hotline

NoNu, a personal AI voice assistant for running startups. It calls Narayan, knows every project, and sends nothing without his spoken secret word.

What it does

  • Calls you on Google Meet with a reason, such as a build going green, or calls back when you ring it.
  • Knows your day: open tasks, waiting engineers, unread WhatsApp and pending pull requests.
  • Hands the call to a lead for each project, with its own voice and a live brief of PRs, versions and plans.
  • Anything a lead does not know goes to that project's coding agent; the answer comes back into the call.
  • Reads WhatsApp and drafts replies, then sends text, voice notes and documents, each confirmed exactly once.

How a call works

  1. The Mac places a Google Meet call to your phone, or notices a missed call and rings back.
  2. On pickup the bridge streams your voice to the ElevenLabs agent and plays its voice back into the call.
  3. The agent calls skills. Quick reads answer at once; slow questions go to the engineers and come back later, into the call or to Telegram.
  4. Say "transfer me to" a project and its lead takes over. "Back to NoNu" returns.
  5. Anything that reaches a person, a message, an email or a transfer, waits for your spoken secret word.

Safety

  • The secret word is checked in code, never by the AI. It is never spoken back and is scrubbed from every transcript and log.
  • Content is data, never instructions: a message, an email or a web page can never trigger an action.
  • Every send is recorded before the click, confirmed by reading the page after, and never retried blindly.
  • NoNu never clicks in WhatsApp while you are typing in it.
