Discord AI Community Manager — Open Source
Lobster Kit makes your Discord server feel alive — without you being online 24/7.
It uses Gemini Flash (free) to:
- Welcome new members with personalized humor (not "Welcome! Read the rules!")
- Chime into conversations when there's something worth adding
- Remember every member — their background, interests, and projects
- Reply when someone responds to the lobster's messages
Zero npm dependencies. Zero database. $0/month running cost.
Battle-tested with 146+ members at Ultra Lab HQ. Join and see it live.

→ Gemini reads username → generates personalized welcome
→ Posts via webhook as "Lobster CEO"
→ Member feels seen → stays and chats
2+ humans chatting in #general → Lobster reads last 20 messages
→ Gemini decides: worth chiming in?
→ YES → posts a relevant comment (then 60 min cooldown)
→ NO → stays quiet
Someone replies to lobster's message (within 5 min)
→ Skips cooldown → generates contextual response
→ Conversation continues naturally
"I'm a physical therapist interested in AI"
→ Extracted: { background: "physical therapist", interests: ["AI"] }
→ Stored in data/member-memory.json
→ Next interaction: "Didn't you say you do rehab? AI can automate your booking system"
Every script has Gemini prompts you can edit. Search for Customize this prompt in the source files.
Examples:
- Professional community → dry humor, helpful tone
- Meme server → chaotic energy, roasts allowed
- Learning community → encouraging, educational

Picks a random blog post → Gemini rewrites it as a 100-200 char teaser → posts to Threads. Never repeats. Perfect for automated content distribution.
