tui

zn

ZenNotes in the terminal: the zn command line and a full terminal app, in one static Go binary.

Notes stay plain Markdown files in a folder you own. zn reads the same vault, config.toml and vault.json as the ZenNotes desktop app, so both can work on one vault, and a self-hosted ZenNotes server works as a remote vault too.

What you get

• The command line. Every command of the desktop app's bundled zn (notes, search, folders, tags, tasks, comments, databases, capture, open, the MCP server), with the same names, flags, JSON shapes and task ids, so scripts written for one work with the other.
• zn tui, the app. Sidebar, tabs, splits, a reading view, Tasks as a list, Kanban board or calendar, Tags, databases with table and board views, templates, daily notes, a command palette, and a Vim engine at the core of everything.
• zn mcp. The same tools the desktop's MCP server offers, for Claude Code, Codex and any MCP client.

Install

zn is a single static binary with no runtime dependencies. Pick one:

Download a release. Grab the archive for your platform from the releases page (Linux, macOS and Windows, amd64 and arm64), unpack it, and put zn somewhere on your PATH:

tar -xzf zn_*_linux_amd64.tar.gz
sudo install -m 755 zn /usr/local/bin/zn

Use Go. With Go 1.26 or newer installed (an older go from 1.21 on fetches the right toolchain by itself):

go install github.com/ZenNotes/tui/cmd/zn@latest

go install prints nothing on success and puts the binary in $(go env GOPATH)/bin, usually ~/go/bin. That folder is often not on PATH, so if zn is "not found" afterwards, add it:

export PATH="$PATH:$(go env GOPATH)/bin"

Build from a checkout with go build -o zn ./cmd/zn.

Either way, zn --version confirms the install. Homebrew and AUR packages are not published yet.

Quick start

Three commands cover every way to get a vault in front of zn. Each one remembers its result and makes it the default, so the next zn or zn tui needs no flags.

zn init ~/Notes                      # create a vault (settings file + a welcome note)
zn vault add ~/Documents/notes       # use a folder of Markdown you already have
zn connect https://notes.example.com # a self-hosted ZenNotes server; asks for the token once
zn tui                               # open it

zn setup asks those questions interactively, and zn tui runs the same wizard when nothing is configured yet. Later:

The list lives in ~/.config/zennotes/workspaces.toml; server tokens go to credentials.toml next to it, readable only by you. Scripts and CI can skip the store with --server <url> and ZENNOTES_REMOTE_TOKEN.

Commands

Every command takes --json; zn --help lists the flags of each one.

The terminal app

zn tui                          # the default vault
zn tui "Project Plan.md"        # open a note straight away
zn tui --vault ~/notes          # a directory
zn tui --server home            # a saved server

Every pane is a framed box with its tab strip above it: the active tab is a filled block, + opens a new note, and the frame's top edge names what the pane shows (editor, preview, database, tasks). :zen drops all the chrome.

Moving around

Space is the leader. Press it and wait a moment for the which-key panel.

The Alt chords (Alt+1…Alt+9 for tabs, Alt+E/S/P for editor, split and preview, Alt+. for zen) work where the terminal sends Option as Alt (Ghostty: macos-option-as-alt = true). Everything they do has a leader or Ctrl+W route as well.

Leader map

Editing

The editor is a full Vim: counts, registers, marks, macros, dot-repeat, undo and redo, text objects, visual, visual line and visual block, search, :s :g :sort :norm with ranges, gq, and heading motions ]] [[. Markdown on top: Ctrl+L toggles the checkbox on the line, gd follows a link, gx opens a URL, gy copies a link, zc zo zM zR fold headings, Enter continues lists, Tab indents list items, [[ opens the note picker in insert mode, and fenced code is syntax-highlighted.

Vim mode follows [vim] enabled in config.toml. With it off, the editor is a plain editor and lists answer only to arrows, Enter and Escape.

Space l e opens the note in $VISUAL or $EDITOR at the cursor line and reloads it afterwards. Ctrl+Z suspends to the shell.

Views

• Tasks has three layouts: list, Kanban board and calendar. Open one with :tasks list|kanban|calendar, Space x, Space k, or the rows under Tasks in the sidebar; v cycles them. x toggles, Enter opens the note at the line, p d w c / set priority, due date, waiting, cancelled and in progress, f filters (#tag, due:today, priority:high, status:x, is:open, -term), m opens the menu. On the board H/L move a card and g regroups by status, priority, due date or any @field. On the calendar Enter lists a day's tasks and o opens its daily note.
• Tags: Tab multi-selects, a toggles any/all, r/x rename or remove a tag everywhere.
• Databases: every .base folder and every loose .csv file, with typed cells (text, number, checkbox, date, select, multi-select, note links), a header row for editing fields, saved filters and sorts, several table and board views, record pages, and a raw CSV toggle. :dbconvert turns a loose file into a folder.
• Home is a dashboard of today's note and tasks, recent notes, the week, favorites and tags. Quick Notes, Archive and Trash are lists with their own actions (u unarchive, r restore, E empty the trash).
• Side panels: Outline (Space p), Connections with backlinks (:connections), Calendar (Space c).

Reading view, embeds and diagrams

Space z p shows the note rendered; Esc or i returns to the editor. Rendering goes through Glamour, the renderer behind Glow; preview_style under [terminal] picks a style (auto, Glamour's built-ins, a JSON style sheet of your own, or zen for the built-in renderer).

• Pictures paint inline in Kitty and Ghostty through the Kitty graphics protocol ([terminal] images = auto|kitty|off); other terminals show a card. Inside tmux, set allow-passthrough on.
• Files (PDF, audio, video, drawings) and YouTube or Vimeo links are cards; Enter opens them.
• ![[Note]] renders the note inline.
• Mermaid blocks draw as text through a pure-Go renderer, or as pictures when mmdc is installed. $$ math renders through typst when it is installed.

Vaults and servers inside the app

:vault (or Space v) lists every saved vault and server, with entries to add a folder or connect to a server. :server <url> connects, asking for the token once. Buffers are saved before a switch, each vault keeps its own tabs, and the vault you switch to becomes the default for the next launch.

Mouse and themes

The mouse works everywhere: click to focus and select, double click to open, right click for the same menus m opens, wheel to scroll, drag to select or to resize the sidebar and splits. mouse = false under [terminal] turns it off. theme_mode under [appearance] is dark, light or system; :theme toggles it.

What stays in the desktop app

Workflows, Atlas, sharing, cloud sync, Harper grammar checks and image resizing. Space l o hands the current note to the app.

Configuration

~/.config/zennotes/config.toml is shared with the desktop app; zn config creates it with comments when it is missing. The sections zn reads:

Per-vault settings (daily notes, favorites, folder layout) live in the vault's .zennotes/vault.json, also shared with the app.

How a vault is chosen

1. --server <name|url> (with --token, ZENNOTES_REMOTE_TOKEN, or the stored token).
2. --vault <name|path>: a saved vault, one the desktop app knows, or a directory.
3. ZENNOTES_VAULT or ZENNOTES_SERVER in the environment.
4. zn's own default, set by zn use, zn connect, zn init or a switch in the app.
5. The workspace the desktop app currently has open.

ZENNOTES_CONFIG_DIR relocates every config file, which is what tests and automation use.

MCP server

zn mcp speaks MCP over stdio against the same vault resolution as every other command. For Claude Code:

claude mcp add zennotes -- zn mcp

For other clients, register the command zn with the argument mcp:

{ "mcpServers": { "zennotes": { "command": "zn", "args": ["mcp"] } } }

The tools match the desktop's MCP server one for one: notes, folders, search, tasks, assets, comments, archive and trash.

Demo recordings

docs/demo/ holds the seeded vaults and the keystroke choreography; record-demo.sh (the tour) and record-kanban.sh (the board) run the app in tmux, capture the terminal stream with asciinema, render it with agg and encode mp4 files with ffmpeg, all without screen capture. Output goes to docs/media/.

brew install tmux asciinema agg ffmpeg
docs/demo/record-demo.sh
docs/demo/record-kanban.sh

Layout of the code

cmd/zn                   entry point
internal/cli             argument parsing, every zn command, help text
internal/tui             the terminal app (Bubble Tea)
internal/vim             the Vim engine, host-agnostic
internal/vault           vault semantics: layout, parsing, tasks, comments, edits, templates
internal/backend         local and remote backends behind one interface
internal/remote          HTTP client for the ZenNotes server
internal/database        databases: .base folders and loose .csv files
internal/mcp             the MCP stdio server
internal/config          config.toml, workspaces, the desktop's app config
internal/keymaps         the bindable-action catalog and overrides
internal/periodic        daily, weekly and monthly note patterns
internal/templates       built-in and custom templates
internal/search          note search scoring

go test ./... runs the suite. The command tables, task grammar, database files and comment sidecars are checked against the desktop app's implementation, so the two stay interchangeable.
