Building Indonesia's digital future through open technology, one project at a time.

YaTTI (Yayasan Teknologi Terbuka Indonesia) has been democratizing technology access across Indonesia since 2014. We build practical open source tools that solve real problems—from navigating complex regulations to preserving cultural wisdom—while advocating for transparency and collaboration in a traditionally hierarchical society.

• peraturan.go.id - AI-powered search for 5,800+ Indonesian regulations. Transforms impenetrable legal PDFs into actionable insights for 66 million SMEs, law firms, and citizens.
• customkb - Build your own AI knowledge bases with vector search, semantic queries, and LLM integration. Powers all YaTTI knowledge systems.
• dejavu2-cli - Elegant terminal interface for querying knowledge bases and interacting with LLMs. Your command-line gateway to AI.

• appliedanthropology - 777,000+ documents bridging anthropology, evolution, and cultural studies. Making academic knowledge accessible.
• seculardharma - Ancient wisdom meets modern science. Ethical living resources for the "spiritual but not religious" demographic.

• en_ID - The missing English (Indonesia) locale. Proper date, time, and currency formatting for software used in Indonesia.
• md2ansi - Beautiful markdown rendering in your terminal. Tables, syntax highlighting, custom themes—because terminals deserve good typography.
• rtfm - Smart documentation search that actually finds what you're looking for. "Read The Fine Manual" made easy.
• checkpoint - Intelligent backup system for developers. Never lose work again.
