A private intelligence layer over your digital life.
Mac-native. Local-first. Entirely yours.
Documents, calendars, email, meetings, tasks, and patterns—all searchable in one place.
Indexes and reasons entirely on your Mac. Nothing leaves your machine.
Acts only with your consent. Every action requires confirmation.
"What did I decide about the hiring plan last month?"
You decided to delay Q1 hiring by 6 weeks and revisit after the product launch.
The central and most important point or place.
Any piece of information worth remembering.
A note is not a document.
In Nexus Note, a "note" is the atomic unit of meaning. Everything worth remembering becomes a note.
Intelligence emerges from connection, not volume. The system links your notes across time and type.
Files, PDFs, and written notes
Calendar entries and meetings
To-dos and commitments
Messages and threads
Audio and video recordings
Remembered choices and settings
Inferred behaviors and routines
Things you want to remember later
Not a note-taking app.
It's a local, private RAG system over your personal knowledge—an orchestration layer that connects documents, time, tasks, and media into a protected intelligence hub.
The best AI is invisible until it matters.
How it works
Ingest
Notes flow in from docs, calendars, tasks, mail, audio, video, and more.
Index
Embeddings and search indexes are built entirely on your Mac.
Reason
A local model answers questions with citations and traceable sources.
Act
Draft, schedule, create—always with explicit confirmation.
All models run on your Mac or infrastructure you control.
Everything stays on your machine unless you configure otherwise.
Export, inspect, or delete anything at any time.
Trust by default
A local-first system should feel like infrastructure: predictable, inspectable, and calm. Your data is portable, under your control, and never a black box.
Built for people who think for a living
Technical professionals, founders, CTOs, and researchers with large personal knowledge stores—who understand AI but don't want their private data in the cloud.
For users who want AI to do things, not just answer questions.

Early access for those who care about privacy, ownership, and local-first systems.
