Lumenook
Private Notes With Sources
Free · Designed for iPad. Not verified for macOS.
Lumenook is a private notebook for the things you'll need again, and an assistant that answers from them with sources.
Today is where the day goes in. Save a quick note, a link, a PDF or a screenshot, or record a voice note. Lumenook transcribes it on your device and suggests the decisions, follow-ups, wins and lessons in it. Nothing is filed until you keep it.
Ask questions across your library and your voice notes. Every answer shows the passages it came from, and Lumenook says so when your notes don't cover something.
Built for iPhone and iPad with Apple Foundation Models on supported devices. Everything stays on your device, with no account, cloud AI, analytics or subscription.
Features:
- capture notes, PDFs, screenshots, links and voice notes
- on-device voice transcription with reviewable suggestions
- daily, weekly, monthly, and quarterly reviews with source links
- work-status and evidence exports from accepted material
- grounded answers with cited passages across your library and voice notes
- Projects, tags and saved searches in Library
- Simple, Standard and Complete interface levels
more This major release starts a fresh library and Daily store without migration. App-managed copies and prior packet data are reset once. Original external files and source archives remain intact.
Daily now supports pasted/imported transcripts, structured capture, suggestion and follow-up editing, searchable history, source navigation, and daily, weekly, monthly, and quarterly reviews with work-status and evidence exports. Protected packets are available in the separate TrustPacket app.
