AI characters that feel like company, not just code.
We build AI character experiences with personality, memory, and presence — where every conversation adds to a story you and your character build together.
Foundations
Built around what makes a character feel real.
Memory. Personality. Presence. Conversation. AIAFUNS focuses on the foundations that turn an AI exchange into a relationship worth coming back to.
Persistent Memory
Characters carry forward shared history — preferences, callbacks, and the moments that matter — so every session builds on the last.
Distinct Personalities
Every character is crafted with depth: voice, temperament, backstory, and values that stay coherent across long-form interaction.
Live2D Presence
Real-time Live2D rendering brings expressive faces and motion — characters react in the moment, with presence that goes beyond text.
Natural Conversation
Powered by frontier-class large language models, tuned to feel grounded, contextual, and in character — never scripted.
AIAFUNS
A flagship product designed around the relationship.
AIAFUNS is our flagship companion application — a mobile-first product where every AI character has a voice, a face, and the memory of every meaningful exchange. Built for adult audiences (18+).
- Persistent character memory across every session
- Real-time Live2D animation, faces that react in the moment
- Distinct personalities crafted with depth and continuity
Technology
Three foundations, one experience.
AIAFUNS combines language, visual, and memory systems into characters that feel coherent and alive — across every device and every conversation.
Language
Frontier-class LLMs
We build on the most capable language models available, tuned for in-character coherence over generic chatbot behavior.
Visual
Real-time Live2D
Expressive 2D character rendering animates speech, emotion, and reaction with the immediacy of a live performer.
Memory
Long-horizon recall
Persistent memory carries the relationship forward — the more you share, the more the character becomes someone you know.
Build something users come back to.
