Pengacara-ku
Hybrid RAG for Indonesia's knowledge domains.

Pengacara-ku is a hybrid retrieval implementation — FTS5 keyword search combined with vector semantic search — with explicit citation to ruling numbers for every answer. Accessed by Indonesian legal professionals in production since Q2 2026.
