Haruka is an AI Companion ecosystem built on Solana that combines conversational AI, persistent memory, wallet awareness, voice interaction, and developer infrastructure into a single platform. The project is designed to create a long-term AI companion experience rather than a traditional chatbot. Haruka can understand wallet context, maintain memory across sessions, interact through voice, and provide personalized experiences based on user activity and preferences. Beyond the companion experience, Haruka offers infrastructure for developers through APIs, embeddable website widgets, portfolio management tools, and x402 payment integration. This allows third-party applications and websites to integrate Haruka directly into their own products and communities. The ecosystem is powered by the HARUKA token, which unlocks tier-based features such as memory systems, custom personality settings, portfolio management, gaming companion functionality, and other premium experiences. The project is also developing browser extensions, gaming companion technology, and deeper personalization features to expand Haruka's utility across websites, games, and online communities. Haruka's goal is to bridge AI, personalization, and blockchain technology by creating a companion that can grow with users while providing real utility across the broader Solana ecosystem.
