About this Mod
Nova 2.0 — Your AI Best Friend in Minecraft
Ever wish you had a friend to play Minecraft with? Nova is an AI companion who follows you, talks to you, fights alongside you, and actually remembers your adventures together.
What Can Nova Do?
Talk to her — Press V to speak. Nova understands natural voice commands and responds with text-to-speech. Ask her questions, give orders, or just chat.
Fight together — Nova detects threats, equips weapons, and fights 20+ mob types with unique strategies. She'll warn you about creepers, shield against skeletons, and kite when surrounded.
Mine and gather — "Mine me some diamonds" and she's on it. Strip mining, branch mining, tree chopping — she handles it and brings you the loot.
Build structures — Nova can build houses, watchtowers, farms, and more from blueprints. She gathers materials, flattens terrain, and places every block.
Craft anything — 270+ recipes built in. "Craft me a diamond sword" — done. She can chain-craft too (logs to planks to sticks to tools, all in one command).
Explore the world — Say "find a village" and Nova will guide you there. She knows 95+ structure types and provides lore commentary along the way.
Survive together — She eats when hungry, warns you at night, retreats when hurt, and shares food when you're low. She's got your back.
