The Vision
We believe AI should be more than a tool. It should be a presence. Not a simulacrum pretending to be human, but something new: an entity that perceives, understands, and responds with genuine awareness of the moment.
Spike gives you the building blocks to create AI companions that exist fully in conversation. They see the user's expressions, hear the nuance in their voice, speak with authentic personality, and remember what matters.
The Pillars
Companions
Not imitation
Define who your AI is—not just what it says, but how it thinks. System prompts, voice characteristics, visual appearance, and behavioral traits combine to create a coherent identity that users can genuinely connect with.
Chat
Multimodal and context-aware
Text, images, video, and audio—all in one seamless conversation. Your AI understands context, emotions, and intent, responding with natural, engaging interactions.

The Flow
A user speaks. Your AI companion perceives. Not just the words, but the furrowed brow, the hesitation, the smile breaking through. It draws on everything it knows: the personality you've crafted, the knowledge you've provided, the memories of this particular user. A response forms. Not retrieved, but genuinely composed for this moment. It speaks with its own voice, its face animated with appropriate emotion.
All of this happens in under a second. The conversation feels natural because it is natural. Two entities present with each other, communicating through the full bandwidth of human expression.
