Open-Source JARVIS Desktop Assistant Built with Claude Code in 2 Days
Project Overview
A developer has created an open-source macOS desktop AI assistant called JARVIS, built in approximately 1-2 days using Claude Code as the primary development tool. The project is described as an MVP but already usable, with a 3D holographic UI featuring an interactive data sphere and glassmorphism panels with cyan glow accents and JetBrains Mono typography.
Core Features
- AI agent with 18 native tools that can: open apps, run terminal commands, manage files, search email, control system volume, and take screenshots
- Voice interface using Whisper for speech-to-text and macOS TTS for text-to-speech with push-to-talk flow
- Integrations with background sync for: Gmail, Google Calendar, Notion, GitHub, and Obsidian
- Daily AI briefing that aggregates user data into a morning summary
- Natural language cron jobs for defining automations in plain English
- Dual model setup with Claude as primary and OpenAI as fallback
Technical Stack
- Tauri v2 with Rust backend
- React + TypeScript frontend
- SQLite for local-first data storage
- No Electron dependency
- ~10MB native binary
- Fully custom UI without component libraries
Current Status and Next Steps
The project is completely free and open source under MIT license. The developer is seeking feedback specifically around agent/tool design, local-first architecture, and UI/UX direction. Planned next steps include API cost tracking, local LLM support via Ollama, and more system-level integrations.
The repository is available at https://github.com/ChiFungHillmanChan/jarvis-ai-assistant.
