How does it work?

Whisperer utilizes the pglite library to store all data locally in IndexedDB. This approach ensures that no data ever leaves the user's device, maintaining privacy and security. Additionally, pglite supports the pgvector extension, allowing Whisperer to implement Retrieval-Augmented Generation (RAG) by leveraging embeddings for more accurate and context-aware AI interactions.
