A production AI platform I built and run 24/7 on my own Linux VPS, several LLM-powered tools in one interface:
• Learn — an AI tutor with spaced-repetition flashcards that generates lessons, quizzes, and hints across subjects, with per-user progress tracking.
• Hub Brain — an autonomous agent that reviews system activity on a schedule and posts grounded, cited summaries (no claim without a source reference), pushed to my phone.
• Dinner — an AI agent that reads my pantry inventory and drafts complete, kitchen-ready recipes nightly via a multi-model LLM cascade (Gemini → Claude → Cerebras), delivered to Discord.
Stack: Python backend, multi-provider LLM integration (Claude, Groq, OpenRouter, Gemini), SQLite, web push, cron scheduling, Caddy + PM2. Shipped and running in production, not prototyped.
