Lumenook

Lumenook helps you save important personal material and turn it into something you can actually use later. Capture quick notes, PDFs, screenshots, copied text, and shared links into a private library built for retrieval first. The Simple experience keeps import, Library search, Ask, citations, and import recovery at the front. Built for iPhone and iPad, Lumenook is designed around Apple Foundation Models on supported devices and keeps the product experience focused on private, local-first understanding instead of cloud-first chat. Core features: - save notes, PDFs, screenshots, copied text, and shared links - ask your library grounded questions with source-backed passages - search by keywords or natural-language intent - review highlighted matches and passage snippets - import or export Markdown notes and review local evidence/source-health checks - choose Simple, Standard, or Complete interface levels in Settings - reveal Projects, folders, tags, saved searches, smart collections, compare, timeline, and diagnostics in Standard or Complete - share into the app from other apps and trigger shortcuts for capture and summary
