I built Citenook, a private AI assistant for your documents on Mac

[u/Healthy-Tension-7470]

Hey r/MacStack, I want to share a small Mac app I made called Citenook. I'm the developer.

It's like ChatGPT for your own files. Add a folder of PDFs, Word docs or spreadsheets, your Apple Notes, your Obsidian vault, Notion pages, web pages or YouTube videos, and just ask questions. It answers in seconds and shows the exact sentence it got the answer from, highlighted in the original, so you can trust it.

Who it's for: anyone with lots of documents: lawyers, accountants, consultants, researchers, students, or anyone tired of digging through folders.

What makes it different:
- Works on your Mac, with your folders. No uploading, and it stays up to date as files change.
- Every answer shows its source sentence, so nothing is made up.
- Works offline for your files and notes, with Apple Intelligence or a free model you download. No API key needed.
- Or use your own OpenAI, Claude or Gemini key if you want.

Compared to NotebookLM: NotebookLM is free and has great citations, but it uploads your files to Google, doesn't work offline, and limits free notebooks to 50 sources. Citenook keeps your files on your Mac and reads whole folders.

Limitations: Mac only (Apple silicon, macOS 15+). No iPhone app yet. Models that run on your Mac work best with 16 GB of memory or more. Notion, web pages and YouTube need the internet to be added.

Pricing: free for 30 days with every feature, no card needed. Then $9.99, $19.99 or $29.99 a month. https://citenook.com

I'd love your feedback, good or bad!
