Embrace your brain.

n-brace is a free, offline-first app for visualizing and navigating your notes as a graph. Follow links instead of folders, and see which topic a note belongs to at a glance.

Move through your notes instead of digging for them.

Navigate

Seamless navigation

Show only the local part of the graph you are exploring. Move through linked notes, jump between nodes with keyboard shortcuts, and let automatic layout keep everything readable.

Edit

Quick graph manipulation

A radial pie menu puts create, link, group and move actions one click away, right where your cursor is. Reshaping the map never breaks your flow.

Radial pie menu: zoom, add, edit and go to tag

See

Tag area view layer

Tags render as colored regions overlaid on the canvas, so you see at a glance which cluster or topic a note belongs to. Filter the view down to just the layers you care about.

Structure

Deep structure

A note can have many flavors and contextual contents. Pizza sits in the whole recipe graph, while the ingredients layer shows only what it is made of. Deep, cross-cutting structures emerge from a flat graph.

Remember

Reminders

Set reminders on any note to resurface repeating tasks, refresh knowledge you don't want to forget, or manage household chores, right from your graph.

Connect

MCP server for AI

A built-in MCP server exposes your note graph to assistants like Claude Desktop and Claude Code. They can search your notes and import web articles as structured, tagged nodes.
