History
William Casarin 77ac91e810 Implement soft keyboard visibility on Android 
- Added `SoftKeyboardContext` enum and support for calculating keyboard
  insets from both virtual and platform sources

- Updated `AppContext` to provide `soft_keyboard_rect` for determining
  visible keyboard area

- Adjusted UI rendering to shift content when input boxes intersect with
  the soft keyboard, preventing overlap

- Modified `MainActivity` and Android manifest to use
  `windowSoftInputMode="adjustResize"` and updated window inset handling

- Introduced helper functions (`include_input`, `input_rect`,
  `clear_input_rect`) in `notedeck_ui` for tracking focused input boxes

- Fixed Android JNI keyboard height reporting to clamp negative values

Together, these changes allow the app to correctly detect and respond
to soft keyboard visibility on Android, ensuring input fields remain
accessible when typing.

Dave - The Nostr AI Assistant

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:

  1. UI Layer - Handles rendering and user interactions
  2. Avatar - 3D representation with WebGPU rendering
  3. AI Client - Connects to language models via OpenAI or Ollama
  4. Tools System - Provides structured ways for the AI to interact with Nostr data
  5. 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

  1. Clone the repository
  2. 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
  3. 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

Contributing

Contributions are welcome! See the issues list for planned features and improvements.
