Loop is an AI-powered podcast creation and listening platform. Create AI-generated talkshow episodes from prompts, synthesize voices, generate cover art, and share them with others. It includes discovery, profiles, and a persistent audio player for a smooth listening experience across the app.

• Authentication: Protected routes using Clerk middleware; public access to /, /sign-in, /sign-up.
• Create Podcast: Compose a show from prompts, select a voice, generate audio, and attach a thumbnail.
• Text-to-Speech Voices: Multiple voice options exposed in voiceDetails (e.g., alloy, echo, fable, onyx, nova, shimmer).
• AI Integrations:
  • ElevenLabs for voice synthesis via app/api/elevenlabs/route.ts.
  • Gemini (Google Generative AI) via app/api/gemeni/route.ts for text/content assistance.
  • Stable Diffusion / Replicate / Hugging Face endpoints for image generation.
• Discovery: Browse and search episodes on /discover.
• Podcast Pages: Detailed pages with metadata and controls at /podcasts/[podcastID].
• Profiles: User pages at /profile/[profileID].
• Persistent Player: Global bottom podcast player managed by providers/AudioProvider.tsx and components/PodcastPlayer.tsx.
• Responsive Navigation: Desktop sidebars (LeftSidebar, RightSidebar) and a mobile sheet nav (Navmod) with active route highlighting.
• Data & Search: Convex database with search indexes on author, title, and description.

• Frontend: Next.js (App Router), TypeScript, Tailwind CSS, shadcn/ui
• Auth: Clerk (middleware.ts, providers/ConvexClerkProvider.tsx)
• Backend/Data: Convex (tables: podcasts, users; storage for audio/images)
• AI Providers: ElevenLabs, Google Gemini, Hugging Face, Replicate, Stable Diffusion

• app/(auth)/*: Auth layout and pages (/sign-in, /sign-up)
• app/(main)/*: Core application routes
  • /home – main feed
  • /discover – discovery and search
  • /create-pod – podcast creation flow
  • /podcasts/[podcastID] – episode detail page
  • /profile/[profileID] – user profile
• app/api/*: AI-related API routes (elevenlabs, gemeni, huggingface, replicate, stable-diffusion)
• components/*: UI components including player, cards, sidebars, and UI primitives
• convex/*: schema, server functions, and generated client bindings
• providers/*: global providers (Clerk+Convex, Audio)

convex/schema.ts defines two tables:

• podcasts: stores audio/image storage IDs, author info, prompts, voice type, duration, and views. Search indexes on author, title, and description.
• users: stores Clerk-linked user profiles (clerkId, email, imageUrl, name).

constants/const.ts defines sidebar routes and available voices:

• Sidebar links: /home, /discover, /create-pod
• Voice presets: alloy, echo, fable, onyx, nova, shimmer

• Node.js 18+
• Convex project URL
• Clerk application (publishable + secret keys)
• API keys/tokens for AI providers you intend to use

Create a .env.local with the following (as applicable):

# Clerk
NEXT_PUBLIC_CLERK_PUBLISHABLE_KEY=pk_...
CLERK_SECRET_KEY=sk_...

# Convex
NEXT_PUBLIC_CONVEX_URL=https://your-team-xxxx.convex.cloud

# AI Providers
ELEVENLABS_API_KEY=...
REPLICATE_API_TOKEN=...
HUGGINGFACE_TOKEN=...
GOOGLE_API_KEY=... # for Gemini

npm install
npm run dev
# open http://localhost:3000

• Clerk Protection: middleware.ts protects all non-public routes; /, /sign-in, /sign-up remain public.
• Global Player: providers/AudioProvider.tsx clears selection on /create-pod to prevent conflicts; components/PodcastPlayer.tsx renders at the app root for persistence.
• Responsive Nav: components/Navmod.tsx uses a sheet-based mobile nav with active state highlighting via usePathname.
• Convex Storage: Audio and images can be stored with storage IDs and referenced via URLs when available.

• app/api/elevenlabs/route.ts – text-to-speech synthesis
• app/api/gemeni/route.ts – Gemini-powered text/content assistance
• app/api/huggingface/route.ts – image or model inference
• app/api/replicate/route.ts – model inference (e.g., image generation)
• app/api/stable-diffusion/route.ts – image generation
