How It Works
From lore to live players in three steps.
Build on the Web
Upload lore documents, define NPC personalities, configure backstories and relationships — all from the dashboard.
Integrate the SDK
Drop the Unity package into your project or call the REST API from any engine. One component, one API call.
Players Interact
Your players talk to AI NPCs that stay in character, draw from your world's lore, and remember every conversation.
Start Building
The Unity SDK is the fastest way to get started. Not using Unity? All platform features are available through the REST API.
Unity SDK
RecommendedDrop in the .unitypackage and add the LoreMindNPC component to any GameObject. The SDK handles conversation history, automatic context gathering from your scene, proximity sensing, location zones, voice input, and memory management.
Why LoreMind?
Production-ready AI infrastructure so you can focus on building great games.
NPCs draw from your lore and react to situational context you pass from your game. Location, time, weather, player state, nearby characters.
NPCs remember who the player is and what they've discussed, across sessions. Memories are automatically extracted and consolidated.
No API keys in your build. We manage authentication, rate limiting, and abuse prevention so you don't have to.
Buy credits upfront when you need them. Never expires. No monthly fees. Volume discounts up to 40% off.
What LoreMind Is NOT
LoreMind NPCs are fully intelligent. They just stay in character.
NPCs draw from your lore for world knowledge. When they don't know something, they deflect naturally, staying in character.
Build Complete Voice-Enabled NPCs
LoreMind handles the intelligence. Combine it with local speech recognition and text-to-speech for fully voice-interactive characters.
Local Speech-to-Text
Works out of the box with local STT models like Whisper. Speech recognition runs directly on the player's device with no cloud overhead or additional cost.
Add Text-to-Speech
Give your NPCs voices by integrating any TTS solution. Use cloud services like ElevenLabs, local models, or pre-recorded audio to bring characters to life.
Complex Relationships
Define NPC relationships, backstories, and personalities. Characters remember context, understand their place in your world, and respond authentically.
Simple, Prepaid Pricing
Buy credits upfront. Use them whenever. Never expires.
