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
Define who they are — we handle the rest
One API for the full companion experience. You provide the identity — name, personality, backstory, visual character. We manage consistent appearance across all modalities, voice, avatar, and persistent per-user memory.
Memory & Presence
They remember. They show up.
Companions don't forget. Every user carries their own context — preferences, history, what matters to them. Each conversation is a continuation, not a reset.
Voice & Avatar
A face. A voice. A presence.
Companions that speak with their own voice and appear with their own face — live and reactive in real time, or rendered on demand. The same character, everywhere they appear.
AI Native Applications
More than chat
Bring the companion into the full fabric of your product. When your application's context and the companion's awareness converge, something new becomes possible — experiences that feel genuinely personal, from guided learning and live gameplay coaching to dashboards that understand what the user actually needs.
The Modalities
Voice
Natural speech synthesis and recognition for fluid conversation
Avatar
Expressive talking heads that speak, emote, and maintain eye contact — real-time or on-demand
Chat
Text-based interactions with full personality and memory
Images
Generate and edit images with AI-powered creative tools
Games
Turn-based games and companion-guided play — the companion as a player or coach
Journeys
Structured courses and adaptive programs that unfold through conversation
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.
