pi-notational

Notational Velocity for Pi coding agent. Search and create notes without friction.

A note-taking tool inspired by Notational Velocity's unified search-and-create flow. Type-ahead search over notes. Press enter to open an existing note, or keep typing to create a new note.

Works as a Pi coding agent extension or a standalone CLI.

Install

Pi extension

Requires Node.js 22+.

pi install npm:@gordonb/pi-notational

Standalone CLI

npm install -g @gordonb/pi-notational

Using

Pi extension

/notational [directory]

Opens a type-ahead finder inside Pi. Type to search. Hit enter to open or create. Notes are edited in Pi's built-in editor.

The flow

1. Type to search — as you type, matching .md files are filtered in real time by title.
2. Arrow keys to navigate — move through the filtered list.
3. Enter to open — select an existing note to edit.
4. Enter to create — if no match exists, press enter to create a new note with that title. A slugified filename is generated automatically (e.g. "How to cook with cornsalt" → how-to-cook-with-cornsalt.md).
5. Esc to cancel — dismiss the finder without doing anything.

If you type a title that happens to match an existing file's slug, the existing note is opened instead of creating a duplicate.

Why Notational Velocity?

Notational Velocity's key insight is that searching and creating are the same gesture. You never have to decide up front whether you're looking for an existing note or starting a new one — just start typing. This removes the friction that keeps people from writing things down.

The same principle applies inside a coding agent. Quick notes, design decisions, scratch thoughts, bookmarks — they all benefit from a flow where capture is instant and retrieval is just as fast.

Note format

Notes are Markdown files with YAML frontmatter:

---
title: How to cook with cornsalt
created: "2026-03-09T06:00:00.000Z"
updated: "2026-03-09T06:00:00.000Z"
---

Buy box of Arm & Hammer raw cornsalt. Sprinkle on poultry before broiling.

• title — the original, un-slugified title
• created — set once when the note is first written
• updated — bumped on every save
• Any additional frontmatter fields you add by hand are preserved across edits.

Standalone CLI

pi-notational also works as a stand-alone CLI.

notational [directory]
notational --help

Run notational to open the note finder. Optionally pass a directory path — defaults to the current working directory. If the directory doesn't exist, it's created.

notational ~/notes

When you select or create a note, the file is opened in $EDITOR (falls back to vi). After you save and quit your editor, you're back at the shell.

# Use with any editor
EDITOR=nano notational ~/notes
EDITOR="code --wait" notational ~/notes

Settings

You can set a default notes directory in a notational.json settings file. There are two locations, checked in order:

File	Scope
.pi/notational.json	Project-local (per working directory)
~/.pi/agent/notational.json	Global (all projects)

{
  "dir": "~/notes"
}

The local file always wins over the global one. The dir field in a local settings file is resolved relative to the working directory; in the global file it is resolved as an absolute path (or relative to the process cwd, so absolute is recommended). Explicit CLI arguments and /notational <dir> always take priority over both settings files.

Development

Requires Node.js 22+.

npm install
npm test
npm run lint
npm run format:check
