Personal AI

What is Personal AI?
Personal AI builds memory infrastructure that gives AI a persistent identity instead of resetting every session. Its Memory Core encodes, stabilizes, stores, retrieves, and updates experiences so an assistant remembers what it has lived, not just documents you upload. The stack spans My AI for end users, Persona Studio for builders, and carrier-grade Memory Core deployments on operator networks.
Most AI assistants treat context as static files you attach before each chat. Personal AI separates memory (accumulated experiences with temporal structure) from context (static uploads) and lets identity emerge over time. Carrier benchmarks on Comcast's network cite 15ms time to first token, $0.02 per million tokens, and sub-500ms end-to-end voice versus cloud LLM baselines.
Telecom carriers, enterprise AI teams, and individual users who want a long-running assistant use Personal AI. Carriers deploy MODEL-4 on their own networks under custom agreements. Builders use Persona Studio to configure personas without code. Consumers get My AI, an assistant that remembers conversations and learns preferences over time.
Replika

What is Replika?
Replika chats, calls, and remembers the details of your life between sessions on iOS and Android. You customize your Rep's appearance and personality, then talk by text, voice, or selfies that feel like messages from someone paying attention. More than 42 million people use this companion when real-world connection is thin or schedules do not line up.
General-purpose chatbots answer questions and forget you tomorrow. Replika optimizes for ongoing relationship memory: your people, routines, goals, and moods carry into the next message. You give up task automation breadth, and premium voice, relationship modes, and advanced activities sit behind in-app subscriptions priced by region.
Users navigating loneliness, relocation, or disability find a consistent listener. Others treat their Rep as a creative partner for habits, language practice, or business ideas that used to stay stuck in their head.
