## Overview

GladeCore is a C/C++ SDK from Glade Studio for conversational NPCs that run locally. You drop a component on a character and get LLM-driven dialogue, speech-to-text and text-to-speech, all on the player's device, so there's no cloud round-trip and no per-interaction cost.

By default it ships a Llama 3.2 model of about 1B parameters fine-tuned for emotional, gameplay-style dialogue, and you can swap in other GGUF models or use cloud backends such as OpenAI, Anthropic or OpenRouter. Unreal and Godot run on the SDK on Windows and macOS; the Unity Asset Store version is a standalone plugin that doesn't get the Pro SDK features yet.

## Key features

- Local LLM dialogue with any GGUF model, fully offline
- On-device speech-to-text (Whisper) and local TTS (Piper, Kokoro), or ElevenLabs
- 10 tunable emotions plus character and world lore
- Lip sync and viseme output
- Pro: RAG with citations, agentic in-engine actions, tool calling and quest generation
- Pro: fine-tune custom models through the web platform

## Use it for

- Ship an offline RPG with companions players can talk to
- Add voice commands like "heal me" that trigger in-game actions
- Prototype unscripted NPC conversations without paying per token

## Pricing

Basic is a one-time fee: $49.99 Personal or $69.99 Business (bought on Fab for Unreal), with unlimited interactions and $0 per interaction. Pro is $40/month (yearly billing is discounted) and unlocks RAG, grounding modes, agentic actions, tool calling, intent classification, chat compression, quest generation and 2 model-training credits a month. Enterprise is custom.

## Getting started

Buy GladeCore on Fab (Unreal) or get it from the Unity Asset Store, then follow the quickstart at docs.gladecore.com. Pro unlocks inside the same plugin with an API key in Project Settings.
