The Identity Layer for Smart AI Communication
SPID is a resolution and retrieval protocol for AI assistants, agents, and applications to access self-contained, voice-ready content units — Smart Packets — complete with transcripts, metadata, intents, and CTAs. It's the future of how AI communicates.
The Problem
AI is everywhere — answering questions, booking appointments, routing support. But today’s internet is a maze of unstructured data, outdated web pages, and scraped content. The result? Confused answers, hallucinations, and missed intent.
The Solution: SPID
SPID replaces guesswork with a structured protocol for delivering real answers. With SPID, content is:
- Structured — Not just a blob of HTML, but voice-ready, AI-readable packets
- Intent-aware — Clear user goals attached to every message
- Routable — Each packet has a globally unique
spid://URI - Voice-ready — Instant playback with transcript and call-to-action logic
- Agent-friendly — Perfect for AI assistants that need to respond intelligently
How It Works
- Smart Packet Format – Modular packets with voice, text, metadata, and CTAs
- SPID URIs – Globally unique IDs like
spid://acme/warranty-lookup - PulseIDs – Async inboxes for agents and people (e.g.,
spid://rick/pulse) - SPID Directory – Public resolution service where agents fetch the correct packet
Real-World Use Cases
- Customer Service AI — Instantly delivers the right answer, not a guess
- Sales Funnels — Voice messages + CTAs drive engagement and conversion
- Personal Voice Inbox — Leave voice messages with intent and reply logic
- Healthcare, Legal, Education — Structured packets replace legacy forms
Why It Matters
SPID isn’t just a protocol. It’s the foundation of a new layer of the internet — one designed for AI agents, voice-first experiences, and structured retrieval.
It’s like DNS for answers.
Like SMTP for structured replies.
Like the missing link between humans and AI.
