Jarvis

Jarvis is a fully local, privacy-first AI voice assistant that runs entirely on your computer without any cloud services or subscriptions. It understands natural conversation — say "Jarvis" anywhere in your sentence and it responds with context-aware, conversational replies. Jarvis maintains unlimited memory across sessions, supports thousands of external tools via MCP integration, and includes a free offline dictation mode as an alternative to cloud-based transcription services.

• 100% Local Processing — all AI inference runs on-device via Ollama; no data ever leaves your machine, and sensitive info like emails, tokens, and passwords is automatically redacted before being saved to disk.
• Conversational Awareness — maintains a rolling short-term context so Jarvis understands multi-person discussions and can answer follow-up questions like "Jarvis, what do you think?" without needing the full question repeated.
• Unlimited Memory — a self-organising knowledge graph learns from every conversation, auto-splits by topic, and surfaces relevant knowledge automatically; a Memory Viewer GUI lets you browse diary entries and the knowledge graph.
• Free Offline Dictation — hold a hotkey, speak, release to paste transcribed text into any app; supports filler-word removal, custom dictionaries, and a dictation history window, all without any cloud round-trip.
• MCP Integration — connect to thousands of external tools including Home Assistant, GitHub, Google Workspace, Slack, Discord, Notion, and databases; smart embedding-based tool selection prevents context rot as you add more tools.
• Built-in Tools — screenshot OCR, web search (DuckDuckGo → Brave → Wikipedia fallback chain), weather, file access, nutrition tracking, and location awareness are included out of the box.
• Natural Wake Word — say "Jarvis" anywhere in your sentence; interrupt with "stop"; follow up without repeating the wake word; echo detection prevents Jarvis from responding to its own speech.
• Adaptive Tone — automatically adjusts communication style to the topic: surgical for code, pragmatic for business, encouraging for wellbeing.
• Cross-Platform Desktop App — pre-built binaries for Windows, macOS, and Linux; a setup wizard guides model selection, Whisper configuration, and MCP server setup on first launch.
• Open Source — written in Python, source available on GitHub under a custom license (free for personal use; commercial use requires contact).
