★ Featured System · O-AI
A local AI that learns & evolves.
O-AI is a fully local artificial intelligence system built by Sankalp Kulkarni. It runs entirely on your own machine — no cloud, no API keys, no data ever leaving your device. Two engines power it: a self-learning core that adapts from every interaction, and an LLM training pipeline for building custom models on your own data.
Self-Learning
Learns from every interaction, expanding its own knowledge graph autonomously.
LLM Training
Train domain-specific models on your own data — full control, 100% private.
Runs Locally
All processing on-device, leveraging your GPU. No cloud risk.
Adaptive
Refines responses over time so the system gets smarter every day.
