Three levels. Type #, ##, or ### at the start of a line, or use /heading1, /heading2, /heading3.

Project Overview

Research Phase

Key Findings

Lists

Bullet (/bullet-list), numbered (/numbered-list), and checklists (/checklist). Toggle a checklist with ⌘⇧C. Indent with Tab.

Bullet list

• Research methodology
• Data collection
  • Primary sources
  • Secondary sources
• Analysis

Numbered list

1. Define hypothesis
2. Gather data
3. Analyze results
4. Write conclusion

Dividers

Type --- on its own line to insert a horizontal rule.

Blockquotes

Two types. Start a line with > for a standard quote (/quote), or use /html-blockquote to embed raw HTML for tweets and styled quotes.

Quote

Formulas

Formulas are live calculations that render as inline pills. They can reference each other by name and update automatically.

1. Inline formulas

Type = followed by a math expression — at the start of a line, after a space, or after punctuation. Press Space or Enter to evaluate. The expression collapses into a pill showing the result.

=1000*12→12,000

2. Named formulas

Give a formula a name by typing name=expression. The name must start with a letter and can contain letters, numbers, hyphens, and underscores. Named formulas display as name: result and can be referenced elsewhere.

revenue=1000*12→revenue:$12,000

3. References

Inside any formula, type the name of another formula to reference its value. A typeahead menu appears after operators (+, -, *, /, () showing available names with their current values. Use arrow keys and Enter to select. References work across notes.

profit=revenue*0.3→profit:$3,600

Hover a formula to see its expression

total:$141,700

TOTAL

$141,700

= q1 + q2 + q3

$52,727

$52,727

= total / 3 * 1.115

Formats are inferred automatically — $ prefix for currency, % suffix for percent, decimals for division. Click any pill to edit it. Press Backspace to convert back to text.

Formulas work anywhere — including table cells

Quarter	Revenue	Growth
Q1 2024	q1:$42,000	12%
Q2 2024	q2:$48,500	15.5%
Q3 2024	q3:$51,200	5.6%
Total	total:$141,700	11%
Projected Q4	$52,727	3%

The Total row uses total=q1+q2+q3, and Projected Q4 uses total/3*1.115 — chaining references for live calculations.

Note Links

Type [[ to search and link to any note, or use /link. Click a link to navigate. Add # to jump to a specific heading within a note.

Images

Type /image to pick a file, drag from Finder into the editor, or paste from your clipboard. Supports PNG, JPG, GIF, WebP, and SVG. Images are stored alongside your notes — no cloud uploads.

Charts

Type /chart-bar, /chart-line, /chart-area, or /chart-donut. Charts render as interactive visuals — click to select, double-click the title to rename, or click Edit to modify the data.

Sketches

Type /sketch to open a drawing canvas right in your note. Draw diagrams and flowcharts. Hold Shift to snap lines. Full undo/redo support.

Inferred Metadata

Every note gets a property card with type, people, tags, status, and a description — inferred from your content so you don't have to fill them in manually. Double-click any field to edit it. Your edits are always preserved.

Type options include meeting, research, brainstorm, journal, task, and more. Status is one of active, paused, or completed. Tags are normalized to lowercase and capped at five.

Moss Agent

Press ⌘K to open Actions. Describe what you want and press ⌘Enter to submit. The agent reads your note for context and writes directly into it.

• Write and edit — draft sections, rewrite paragraphs, fix grammar
• Research — search the web and pull findings into your note
• Organize — restructure sections, summarize content
• Review — leave inline comment suggestions on your writing

Selection Context

Select text before pressing ⌘K to scope your action to that passage. The selection appears as a context pill in the action, so the agent knows exactly what to work on.

@ Mentions

Type @ in Actions to reference other notes, skills, or external directories. The agent reads the referenced content as additional context.

Skills

Skills are reusable instruction sets that shape how the agent works. Moss ships with defaults for note-writing, research, and more. Write your own or ask the agent to generate one for you.

Timeline

Every agent run is saved to the timeline on your note. Scroll through past actions to see what changed, or revert to any previous version.

Comments

Select text and press ⌘⇧A or click the comment button in the floating toolbar. Comments appear as highlights — click to open a popover where you can edit, delete, or send the comment to the agent.

Comments + Agent

Comments and the agent work together. Instead of asking for broad rewrites, use comments for precise, targeted collaboration.

External Directories

Edit any markdown file

Open any markdown file on your computer and edit it right in Moss — with all the rich features. Your Obsidian vault, Claude Code plans, project docs. Files stay where they are, changes save back to the original. No importing, no copying, no migrating.

Expand the agent's knowledge

Give Moss access to any folder or file in Settings — like a codebase, a research archive, or a project directory. The agent can instantly read and search everything inside. Type @ in Actions to mention a directory, and the agent brings it into the conversation. Ask questions about your code, plan features from existing specs, or write documentation grounded in what's already there.
