What is NoteFlow

Quick notes. Zero friction.

A dark-first desktop notebook for technical people. It lives in your system tray, writes plain Markdown to your own disk, and stays out of the way until you need it. The brain is optional — the speed isn't.

A brain that mirrors you

NoteFlow turns your notes into a living 3D neural graph. The more order you give them, the more legible your brain becomes — clusters form, neurons connect, structure emerges.

  • Tidy groups → clean clusters
  • Linked notes → stronger connections
  • Each section is its own neuron

Organize on the left, watch it take shape in the Brain view.

The Brain · Local AI

Every note becomes a neuron.

A semantic index turns your notes into a living graph. Structure you built is wired in solid lines; relationships the AI found light up as synapses through the core. Ask a question and the notes it used glow.

01 / GRAPH

Two layers of connections

Solid lines are the hierarchy you built. Faint synapses are what the AI noticed — even across different groups.

02 / CHAT

Chat with your notes

RAG answers stream with clickable citations — and the agent can create, move and organize notes for you.

03 / PRIVATE

100% local & yours

The semantic index never leaves your machine. Bring your own model key — Anthropic, OpenAI, Ollama, anything.

Profile · The second brain

An AI that actually knows you.

No essay about yourself. NoteFlow asks the easy stuff — a few favorites, some this-or-that — and infers who you are from what those choices tend to mean. Then it writes your profile as an editable note.

How you work
You think in systems and reach for depth over breadth. A planned runway beats improvisation; you ship early, then refine.
How to talk to you
Direct and concise. Skip the warm-up — lead with the answer, then the reasoning.
inferred from 6 answers · 2 documents · editable like any note

Described in abstract traits — never by the exact titles you gave. Favorites stay in a low-relevance section the AI is told not to bring up unprompted. The model reads your documents directly; NoteFlow never stores them on a server.
