Problem

Getting a group together with a good dungeon master is the hardest part of tabletop roleplaying — and most AI DMs lose the plot after a few turns.

Solution

A guided character-creation flow (roll race/class, allocate stats, choose exactly 5 abilities from 20 offers), campaign lobbies for playing with friends, and a Groq-powered AI DM that narrates scenes and consequences with persistent state in Supabase.

Features

  • Supabase auth with character-gated protected routes
  • Hero creation: lore, race/class rolls, stat allocation, 5-of-20 ability kit
  • Create or join campaign lobbies with friends
  • Groq-powered AI Dungeon Master narration
  • AI-generated hero art

Architecture

Next.js 16 with a custom server; Supabase for auth and campaign persistence; Groq for low-latency DM narration via the Vercel AI SDK; Gemini/HuggingFace for character art. Playwright QA suites cover the full game loop.

What I built

  • End-to-end game loop from auth to campaign play
  • Ability-draft character system
  • AI DM integration with scene state
  • Playwright playthrough test suites

Challenges

  • Keeping AI narration consistent with campaign state across turns
  • Gating game routes behind an active character

Results

Deployed and playable on Render with the full create-a-hero → play-a-campaign loop.

Next steps

  • Richer combat resolution
  • Persistent world events between sessions
