Citenook for Mac

Stop digging through your files.

Ask in plain words. Citenook finds the answer across every PDF, note and document you have, and shows the exact sentence it came from. All on your Mac.

Download for Mac See how it works

For Macs with Apple silicon, macOS 15 or later

The answer is in your files somewhere. That's the problem.

“Which version did we sign?”

Contracts, invoices and notes are spread across folders, versions and downloads. One clause means opening twenty files.

“Is that really what it says?”

Chatbots answer with confidence, and sometimes they're wrong. Without the source, you can't tell which time is which.

“Can I paste this into ChatGPT?”

Client work, contracts and personal papers shouldn't end up on someone else's servers just to get an answer.

Citenook solves all three. Scroll to see how.

1
Everything you know, in one place.
Add folders, PDFs, notes, web pages, even YouTube videos. Citenook reads them on your Mac and stays in sync as they change.
2
Ask like you'd ask a colleague.
No keywords, no remembering which file it was in. Just the question.
3
Answers in seconds, not hours.
A short, clear answer written only from your files. No guessing, no web search.
4
Trust it, because you can check it.
Every fact links to the exact sentence and page it came from. One click, and the proof is in front of you.
5
For the files you'd never paste into ChatGPT.
Turn off Wi-Fi and it still answers. With a model on your Mac, contracts and client files never leave it.
6
Your AI, your choice.
Free models on your Mac for everyday questions, or your own OpenAI, Anthropic, Google or OpenRouter key for the hard ones. No lock-in to one AI company.
7
Answers come to you.
Writing an email or a report? Select text and press ⌥ Space. No switching apps, no copy and paste.

How Citenook works with your files

Everything is read and searched on your Mac. You choose what writes the answer, and every answer shows where it came from.

1
Add your files to a brain
One brain per client, project or subject. Add folders, PDFs, notes, web pages and videos.
2
Citenook reads them on your Mac
Your files are indexed and searched on your Mac. Before anything goes to an online AI, names, emails and ID numbers can be swapped for placeholders.
3
Ask, and see the source
A model on your Mac or your own AI key writes the answer, and every fact links to the exact sentence it came from.

AI is only useful if you can trust the answer, and only safe if your files stay yours. Citenook was built for both.

Private by default. Powerful when you need it.

Your files are read, searched and kept on your Mac. You decide what writes the answer, one chat at a time.

Most private

A model on your Mac

Apple Intelligence, or a free model you download once. Works offline. Nothing leaves your Mac.

Best answers

Your own AI key

OpenAI, Anthropic, Google or OpenRouter. File names stay on your Mac, and names, emails and ID numbers can be hidden before sending.

Already set up

Ollama or LM Studio

Use the models you already run. Citenook finds them on its own.

Everything you've saved, finally searchable.

PDFPDFs DOCWord XLSSpreadsheets MDText and Markdown ♪Recordings, transcribed on your Mac ✎Apple Notes wwwWeb pages ▶YouTube videos NNotion

Every client in its own space

Keep clients, projects and subjects apart, so answers never mix them up. Or ask across everything.

Hard questions, thorough answers

For questions that span many files, Deep answer searches several times before it writes.

Writes the way you do

Replies and rewrites in a style Citenook learns from a few of your own emails.

Do the weekly work once

Save steps you repeat, like “what's due this week, written as an email”, and run them in one click.

Why not just use ChatGPT?

Chatbots know the internet. Citenook knows your files, and shows you where it read each answer.

Questions

Does Citenook work offline?

Yes. With Apple Intelligence or a model you've downloaded in Settings, everything happens on your Mac and no internet is needed. Online AI services, web pages and YouTube need a connection.

Do I need an OpenAI or other AI account?

No. Models on your Mac are free to use. If you want an online AI, add your own key from OpenAI, Anthropic, Google or OpenRouter in Settings; you pay them directly for what you use.

What gets sent when I use an online AI?

Your question and the passages chosen for that answer, nothing else. File names aren't sent, and you can hide personal details like names, emails, phone numbers and ID numbers. You can also preview exactly what will be sent before it goes.

Which files can it read?

PDFs, Word documents, spreadsheets, text and Markdown, audio recordings (transcribed on your Mac), Apple Notes, web pages, YouTube videos and Notion pages.

Which Macs does it run on?

Macs with Apple silicon (M1 or later) on macOS 15 or later. Models on your Mac run best with 16 GB of memory or more; with 8 GB, Apple Intelligence or an online AI is the better choice.

Are my files used to train AI?

Citenook never uses your files to train anything. Online AI services handle requests under your own account and their terms.

How do I get help?

Write to support@citenook.com, or choose Help → Contact Support in the app.

Your files have the answers. Now you can find them.

Less time searching. Every answer with its proof.
