What is Nookmind?
A tutor that has read every page you own.
Nookmind is an offline AI study app for Windows and Mac, made by MeJuvante, that answers your questions only from your own PDFs, Word files and notes — with the exact file and page. The AI runs on your PC, so your files are never uploaded. Think of it as a study partner who never forgets a page and never shares your notes.
- § 01
Make a study board
One board per subject — Biology, Law, Networking. Each keeps its own files, index, chat and progress.
- § 02
Add your files
PDFs, Word documents, notes, whole folders with thousands of files. New files are picked up on refresh.
- § 03
Ask, and check the page
Answers come from your material only, with the file and page — so you can trust and verify them.
Features
Built for real studying, not for demos.
Answers with the exact page
Every answer lists its sources. One click opens the passage it came from.
Fully offline AI
The AI “brain” runs on your own processor or graphics card. No cloud, no monthly API bill.
Speak and listen
Dictate questions with your microphone and let Nookmind read answers aloud — all on-device.
Huge folders, no problem
Connect a folder with thousands of files. Nookmind reads in the background and keeps up with changes.
Picks the right brain for your PC
A 10-second scan checks memory, graphics and disk, then recommends the model that runs smoothly.
Secure sign-in, quick PIN unlock
Sign in with your Google or Microsoft account. After that, lock and unlock with your own PIN — or your laptop’s Windows Hello PIN.
Know what is done and what is next
Each document is split into its parts. Tick a part when you finish it, see what is in progress, and ask “where did I stop?” to pick up at the right page.
How it works
