Remi

remi

The CLI that Apple should have built for Reminders.

Create lists, add reminders, organize them into sections, and have everything sync across all your Apple devices — from the terminal.

Why remi?

• Sections with iCloud sync — the only CLI that supports Apple Reminders sections. Create them, assign reminders, move between them, and it all syncs.
• Natural language — --due "next tuesday", --repeat "every 2 weeks on monday,friday"
• Fuzzy matching — type remi list shopping instead of remi list "Groceries / Shopping List"
• Agent-first — structured JSON output, Claude Code plugin, skills.sh skill, OpenClaw compatible
• Fast — compiled Swift helpers, no Electron, no GUI

vs other tools

Install

brew tap mattheworiordan/tap && brew install remi

Or via npm:

npm install -g @mattheworiordan/remi

or run without installing

npx @mattheworiordan/remi lists

Quick start

remi lists                                              # See all lists

remi list "Groceries" # View a list (fuzzy: remi list groceries) remi add "Groceries" "Buy milk" --section "Dairy" # Add to a section remi today # What's due today? remi complete "Groceries" "milk" # Fuzzy complete

Usage

Check what's due

remi today                    # Due today

remi overdue # Past due remi upcoming --days 7 # Coming up remi search "dentist" # Search across all lists

Manage reminders

remi add "Work" "Review PR" --due "next friday" --priority high

remi add "Work" "Standup" --due tomorrow --repeat daily remi complete "Work" "standup" remi update "Work" "Review PR" --due "in 3 days" remi delete "Work" "Review PR" --confirm

Dates: tomorrow, next tuesday, in 3 days, or YYYY-MM-DD Recurrence: daily, weekly, monthly, every 2 weeks, every 3 months on monday,friday

Organize with sections

remi sections "Groceries"                                # List sections

remi create-section "Groceries" "Produce" # Create a section remi add "Groceries" "Bananas" --section "Produce" # Add to a section remi move "Groceries" "Bananas" --to-section "Dairy" # Move between sections

Sections sync to iCloud via CRDT vector clocks. See how it works.

JSON output

Every command supports --json for machine-readable output:

remi today --json

{"success": true, "data": [...]}

AI agent integration

remi is designed for AI agents. Use it as an MCP server, Claude Code plugin, or skill:

MCP server

{

"mcpServers": { "remi": { "command": "remi", "args": ["--mcp"] } } }

16 tools: remi_lists, remi_add, remi_complete, remi_move, remi_today, remi_search, and more — all with fuzzy matching and structured responses.

Other integrations

# Claude Code plugin

claude plugin marketplace add mattheworiordan/remi

skills.sh

npx skills add mattheworiordan/remi

OpenClaw

clawhub install remi

Permissions

On first run, macOS will ask you to grant Reminders access (click Allow). Section features also need Full Disk Access for your terminal app.

remi authorize    # Guides you through both

remi doctor # Shows what's granted

Requirements

• macOS 13+ (Ventura or later)
• Node.js 18+
• Xcode Command Line Tools (xcode-select --install)

How it works

remi uses three layers because Apple never exposed sections in their public API:
