## LumenNote Description
1. LumenNote turns your PDFs, documents, audio recordings, photos, and notes into a private, searchable knowledge base you can actually talk to.
2. Drop a research paper, a lecture recording, a screenshot of a dense slide, or a chapter you typed from a book. LumenNote transcribes audio and OCRs images right on your iPhone — nothing leaves your device unless you explicitly ask the AI a question. Everything is chunked,indexed, and ready for instant recall.
3. ORGANIZE AROUND SPACES: Each Space is a topic: a research project, a course, a book you're working through. Sources live inside a Space. Ask questions and the AI only looks at material you've put in the current space — not the internet, not other spaces, not some stranger's feed.
4. EXTRACT INSIGHTS WORTH KEEPING: When the AI tells you something useful, long-press and tap Extract. LumenNote distills it into a short, standalone insight linked back to its source. Review insights in your inbox, save the ones worth keeping. Saved insights feed back into future answers so the AI keeps getting sharper about your material.
5. EXPLORE FOR NEW ANGLES: Once you have three or more insights in a space, tap Explore. LumenNote cross-pollinates three random insights through the AI to surface patterns, contradictions, or questions you hadn't noticed. Useful when you want to look at your own notes from a fresh angle.
6. PRIVACY-FIRST ARCHITECTURE: Your Spaces, sources, transcripts, insights, and chat history all live on your device. The only data that leaves your phone is the text you explicitly send to the AI (routed through our gateway to OpenAI, Anthropic, or Google), plus account settings and any feedback you submit. No ads. No trackers. No selling your data.
7. FEATURES
  • Import PDFs, RTF / HTML / plain-text docs, MP3 / M4A / WAV / AIFF / CAF audio, JPEG / PNG / HEIC images, and typed text
  • On-device speech-to-text and OCR (works offline, powered by Apple's Speech and Vision frameworks)
  • AI chat scoped to a space or specific sources
  • Three insight statuses: Pending Review, Saved, Dismissed — dismissed ones are always restorable
  • Markdown rendering in AI replies
  • Light / dark mode, auto-switching 
8. SUBSCRIPTION TIERS
  • Free — 2 spaces, up to 10 sources, 10 AI chats and 3 insight extractions per 30 days 
  • Mini ($0.99/mo) — Unlimited spaces and sources; AI quota matches Free
  • Pro — Unlimited content + 1000 AI chats and 100 insight extractions per 30 days
  • Max — Unlimited content + 5000 AI chats and 500 insight extractions per 30 days   
9. BUILT FOR: Researchers sifting through PDFs. Students turning lecture audio into study notes. Writers interviewing sources. Anyone whose knowledge 
  lives in a pile of files and needs a way to actually use it.
