Getting Started with Cabinet

Cabinet is an AI-first knowledge base. Everything lives as files on disk — no database, no cloud lock-in. You write pages in markdown, organize them in a tree, and let AI agents help you edit and maintain the whole thing.

Already installed? This page is the in-app onboarding tour, mirrored for the web. If you're brand new, start with Install Cabinet first.

Editor — Notion-grade writing

The WYSIWYG editor runs on Tiptap. Everything you type roundtrips to plain markdown on disk.

Headings, lists, and styling

Select any text and the bubble menu appears. Use it for bold, italic, underline, ~~strike~~, code, super^script, sub_script, alignment, and links.

Text color and highlights

Pick text color or background highlight from the toolbar or bubble menu. They roundtrip through markdown as inline HTML.

Red urgency notes for incidents
Green confirmations for shipped items
Yellow highlights for key terms
Blue backgrounds for cross-references

Images — paste, drop, or URL

Three ways to add an image, all save the file next to this page on disk:

Paste a copy-pasted screenshot — it uploads and inserts automatically
Drag & drop a file from Finder onto the editor
Click the image icon on the toolbar, or type /Image, and use the Upload tab or From URL tab

Hover any image and drag its side handles to resize — the width persists across reloads.

Videos and universal embeds

Click the video icon or type /Video to upload a file or paste a direct video URL. Click the embed icon (sparkles) or type /Embed for YouTube, X, Vimeo, Loom, TikTok, Spotify, Facebook, Instagram, or any URL — Cabinet auto-detects the provider.

Supported providers when you type /Embed:

Provider	Paste a link like…
YouTube	`https://youtube.com/watch?v=…`
Vimeo	`https://vimeo.com/…`
Loom	`https://loom.com/share/…`
X / Twitter	`https://x.com/user/status/…`
TikTok	`https://tiktok.com/@user/video/…`
Facebook / Instagram	any public post URL
Spotify	`https://open.spotify.com/track/…`
Anything else	Falls back to a generic iframe

Pasting a recognized URL on an empty line auto-embeds without the popover.

Slash commands

Press / on an empty line to open the command menu, grouped into Basic, Media, and Advanced.

Group	Commands
Basic	Text, H1/H2/H3, Bullet, Numbered, Checklist, Code block, Quote, Divider, Table
Media	Image, Video, Embed, File
Advanced	Callout, Warning, Math, Emoji

Callouts

Use /Callout for info blocks and /Warning for alerts:

Tip. You can drop a file onto an already-open page and it saves straight into the page's directory — no need to move it manually.

Heads up. Don't edit files inside .git, .history, or .jobs — Cabinet owns those.

Math, emoji, checklists

Type /Math or wrap in $…$ / $$…$$ — KaTeX renders inline, e.g., $E = mc^2$
Type /Emoji for a picker, or paste unicode directly 🚀
Type /Checklist for a task list

Drag handle

Hover any block and a ⋮⋮ handle appears in the left margin. Drag it to reorder paragraphs, lists, embeds, or images.

Wiki-links and mentions

Type <a data-wiki-link="true" href="#page-name" class="wiki-link">Page Name</a> to link another page (autocompletes the slug). In the right-side AI panel use @PageName to attach pages as context for the agent.

Source mode

Every editor view has a Source toggle in the top-right. Click it to see (and edit) the raw markdown that will be written to disk.

Core features

Keyboard shortcuts

Shortcut	Action
`⌘K`	Open search
`⌘S`	Force save
