💬 Discord Companion — a personal assistant that lives in my Discord

I DM'd Jarvis from my phone at midnight. It checked my Google Calendar, cross-referenced a note from last week, and answered — running on the Mac mini in my closet.

I have a private Discord server with two channels and one user (me). Jarvis lives there. I can DM it from my phone, my laptop, or my watch — anywhere Discord runs. Sample things I've asked it this week:

• "What's the address of the place I had that meeting last Tuesday?" → Jarvis searches my calendar + meeting notes, replies in 4 seconds.
• "Reply to Mom's text from earlier saying I'll call tomorrow at 7." → drafts a reply, asks me to confirm, sends.
• "Add 'Sam's birthday is March 12' to my long-term memory." → updates MEMORY.md, confirms.
• "Summarize the last hour of conversation in #deploys-prod." → reads the Slack channel via MCP, summarizes.

I used to use my phone's voice assistant for this. The two differences that matter: Jarvis answers in three sentences, not one, and it actually has my context — my notes, my calendar, my projects, my history.

Why it's nice

• Latency feels like talking to a person. Local inference on a modest GPU is 5–10× faster than round-tripping to a cloud API. Question to answer in 3 seconds.
• The Discord interface is multi-device for free. Same conversation thread on my phone, laptop, watch — no special app to install.
• It's already private. A Discord server I run, talking to a model on a machine I own. The data trail is two endpoints I control.

How I set this up

→ Tutorial: Messaging Hub is the closest match — same channel-adapter + orchestrator-agent pattern, with Discord substituted for Slack.

→ Channel docs walks through Discord/Slack/Telegram/WhatsApp setup. Discord is two environment variables and a bot token.

→ MCP integration guide if you want Jarvis to reach into Notion, Linear, Gmail, etc.
