## What is Lumina?

Lumina – Your Ideas, Connected

Lumina is a private, local-first second brain that helps you capture your thoughts, connect ideas, and rediscover everything you’ve learned — instantly.
All processing happens on your device. Your data stays yours.

Think. Capture. Connect.

Write notes, record voice memos, scan text, or import information — Lumina automatically identifies names, concepts, and entities and links them together for you.

Built-in offline AI lets you search and understand your knowledge base with natural language, without sending anything to the cloud.

A Smarter Way to Remember

Entities & Connections – Lumina detects people, places, topics, and ideas across your notes and maps how they relate.

AI Search (Offline) – Ask questions in your own words and get accurate answers powered by a local LLM.

Voice & OCR Capture – Transcribe audio or extract text from images quickly and privately.

Knowledge Graph – Visualize how your notes and ideas connect. Explore your mind like a map.

Simple by Design – No folders, no friction. Just capture and let Lumina organize.

Private & Local – Notes, embeddings, AI models — everything stays securely on your device.

Optional iCloud Backup – Encrypted, effortless backups to restore your knowledge on a new device.

Export Anytime – Your data is yours. Export it in an open format whenever you want.
