Dave is an AI-powered assistant for the Nostr protocol, built as a Notedeck application. It provides a conversational interface that can search, analyze, and present Nostr notes to users.

Overview

Dave demonstrates how to build a feature-rich application on the Notedeck platform that interacts with Nostr content. It serves both as a useful tool for Nostr users and as a reference implementation for developers building Notedeck apps.

Features

Interactive 3D avatar with WebGPU rendering
Natural language conversations with AI
Query and search the local Nostr database for notes
Present and render notes to the user
Tool-based architecture for AI actions
Context-aware searching (home, profile, or global scope)
Chat history persistence
Anonymous lmzap backend

Technical Details

Dave uses:

Egui for UI rendering
WebGPU for 3D avatar visualization
OpenAI API (or Ollama with compatible models)
NostrDB for efficient note storage and querying
Async Rust for non-blocking API interactions

Architecture

Dave is structured around several key components:

UI Layer - Handles rendering and user interactions
Avatar - 3D representation with WebGPU rendering
AI Client - Connects to language models via OpenAI or Ollama
Tools System - Provides structured ways for the AI to interact with Nostr data
Message Handler - Manages conversation state and message processing

Usage as a Reference

Dave serves as an excellent reference for developers looking to:

Build conversational interfaces in Notedeck
Implement 3D rendering with WebGPU in Rust applications
Create tool-based AI agents that can take actions in response to user requests
Query and present Nostr content in custom applications

Getting Started

Clone the repository

Set up your API keys for OpenAI or configure Ollama

export OPENAI_API_KEY=your_api_key_here
# or for Ollama
export OLLAMA_HOST=http://localhost:11434

Build and run the Notedeck application with Dave

Configuration

Dave can be configured to use different AI backends:

OpenAI API (default) - Set the OPENAI_API_KEY environment variable
Ollama - Use a compatible model like hhao/qwen2.5-coder-tools and set the OLLAMA_HOST environment variable
