+# Daily Digest Podcast - Implementation Complete
+
+**Task:** Research and build a digital podcast solution for the Daily Digest blog
+**Status:** ✅ Complete (Ready for Review)
+**Date:** 2026-02-23
+
+## What Was Delivered
+
+### 1. Research Findings
+- **TTS Providers**: OpenAI TTS ($2-4/month, best quality) vs Piper (free, local) vs macOS say (free, basic)
+- **Audio Storage**: Supabase Storage (free tier 1GB)
+- **RSS Feed**: Next.js API route with iTunes extensions
+- **Integration**: Async TTS generation triggered after digest post
+
+### 2. Implementation
+
+**Core Services:**
+- `src/lib/tts.ts` - Multi-provider TTS abstraction (OpenAI, Piper, macOS)
+- `src/lib/storage.ts` - Supabase Storage audio upload/management
+- `src/lib/podcast.ts` - RSS generation utilities
+
+**API Endpoints:**
+- `GET /api/podcast/rss` - RSS 2.0 feed for podcast apps
+- `POST /api/digest` - Updated to trigger async TTS generation
+
+**UI Pages:**
+- `/podcast` - Web audio player with episode listing
+- Updated blog post view with inline audio player
+- Added podcast link to header navigation
+
+**Scripts:**
+- `npm run generate-tts -- <post_id>` - Generate audio for specific post
+- `npm run generate-tts:all` - Batch generate for all missing posts
+
+**Documentation:**
+- `PODCAST_SETUP.md` - Complete setup guide
+- `PODCAST_ARCHITECTURE.md` - Architecture overview
+- `PODCAST_SUMMARY.md` - Implementation summary
+
+### 3. Key Features
+- ✅ Automatic TTS when new digest posted
+- ✅ RSS feed compatible with Apple Podcasts, Spotify
+- ✅ Web audio player on podcast page
+- ✅ Multiple TTS provider options
+- ✅ Free tier coverage (Supabase storage + Piper TTS = $0)
+- ✅ Async processing (doesn't block post creation)
+
+### 4. URLs
+- RSS Feed: `https://blog-backup-two.vercel.app/api/podcast/rss`
+- Podcast Page: `https://blog-backup-two.vercel.app/podcast`
+
+### 5. Next Steps for Deployment
+1. Run SQL to add audio columns to database
+2. Add `ENABLE_TTS=true` and `OPENAI_API_KEY` to Vercel env vars
+3. Deploy: `npm run build && vercel --prod`
+4. Submit RSS to Apple Podcasts, Spotify
+
+### 6. Files Modified/Created
+- 13 files changed, 1792 insertions
+- Committed to main branch
+
+## Cost Analysis
+- OpenAI TTS: ~$2-4/month (optional)
+- Piper/macOS TTS: $0
+- Supabase Storage: $0 (within free tier)
+- Total: $0-4/month depending on TTS provider
