Innovative EVA AI Assistant Development

EVA (Enhanced Virtual Assistant) is a local-first, voice-enabled AI agent framework that acts as a programmable overlay on the operating system — essentially your own "Jarvis" for task automation, app control, and system interaction via natural language.

Core Architecture
LLM Layer: Swappable backend (default: OpenAI GPT-4o, optional: local LLMs via Ollama)

Routing Layer: Natural language → Intent classification → Plugin execution

Plugin System: Each command is mapped to modular Python plugins (e.g., open apps, file manipulation, terminal commands)

Voice Pipeline: Whisper STT → Hotword activation → Command transcription

Memory Layer: Local context management via SQLite or vector store (WIP)

Execution Flow
User speaks or types: "Open Notion and summarize my to-dos"

Input is transcribed (if voice), then passed to the router

Router uses lightweight NLP parsing or LLM to extract intent

Plugin is dispatched (open_app, summarize_notes, etc.)

Output is returned to user via voice or GUI overlay

Tech Stack
Language: Python (async-enabled), with modular file structure

AI Interface: llm.py handles API calls (OpenAI, Anthropic, Ollama)

Plugins: Drop-in .py files registered dynamically (agent/plugins/)

Scripts: Shell integrations (e.g., for file system, app launching)

Audio: Whisper for STT, PyAudio or VAD for hotword detection

Philosophy
Local-first execution, minimal cloud dependency

Extensible: engineers can build plugins in minutes

Private: designed to keep user data on-device

Your Role
Build and scale plugin infrastructure

Optimize the LLM routing layer for speed, fallback logic, and reliability

Integrate event-driven triggers (e.g., scheduled reminders, file watchers)

Expand support for local LLMs and offline execution

EVA is not just a chatbot. It’s a programmable AI command line for humans, designed to make interacting with your computer as seamless as talking to an assistant.
