• Postgres database hosted on Supabase, with pgvector for embedding similarity search.
• Text Ingestion: Chunking using chonkie, tagging characters and places using gpt-4o-mini.
• Audio Alignment: using ctc-forced-aligner.
• Audio storage: on Cloudflare R2.

Frontend:

• React, TypeScript, Vite
• React Router for client-side routing
• react-markdown for rendering segment content
• CSS Modules for scoped styling
• Vitest, Testing Library for tests
