Everything Citenook does with your files.

Citenook is a private Mac app that answers questions from your own files and shows the exact sentence each answer came from. Here is all of it, in one place.

Answers you can check.

Every fact in an answer has a small number next to it. Click it and the file opens at the passage, with the exact sentence highlighted, and the page number for PDFs. If your files don't say something, Citenook tells you so instead of guessing.

Only from your files

Answers are written from what you've added. No web search, no made-up facts.

The exact sentence

Not just the file name: the sentence and page the fact came from.

Hard questions

Deep answer searches several times across many files before it writes.

Follow-up questions

Ask the next question in the same chat. Chats are saved on your Mac.

Everything you've saved.

Add folders and files, and Citenook keeps them up to date as they change. No uploading, no re-adding.

PDFs Word Spreadsheets Text and Markdown Recordings, transcribed on your Mac Apple Notes Obsidian vaults Web pages YouTube videos Notion

A brain for each client, project or subject.

A brain is a set of files you ask questions about. Keep each client in its own brain so answers never mix them up. Put related brains in a group to ask across all of them at once, or ask across everything.

You choose which AI answers.

Pick per chat. Your files are read and searched on your Mac whichever you choose.

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.

Private by design.

Works offline

With a model on your Mac, turn off Wi-Fi and it still answers.

Personal details hidden

Names, emails, phone numbers and ID numbers can be swapped for placeholders before anything goes to an online AI.

See what is sent

Preview exactly what will go to an online AI before it goes. File names never do.

No analytics in the app

No tracking, no account. Read the privacy policy.

Help where you write.

Quick Ask

Select text in any app and press ⌥ Space to ask about it. No switching apps.

Your writing style

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

Workflows

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

Your instructions

Tell Citenook how you like answers: shorter, in bullet points, in another tone.

What you need

A Mac with Apple silicon (M1 or later) and 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.
An online AI is optional: bring your own OpenAI, Anthropic, Google or OpenRouter key and pay them directly.
