A private, offline notes app for your whole life — budgets, journals, trip plans, and to-do lists, organized by an AI and stored on your computer, not in the cloud.
Structure in the background
Moss tags and organizes your notes so you don't have to. It finds connections and keeps everything linked while you focus on writing.
A shared workspace
You highlight, annotate, revise. Moss does the same. Communication happens inline and on the page.
Start simple, add power inline
Rich text formatting, formulas, charts, live data. Every layer is optional, for you and Moss to use.
Your notes are yours
Every note lives on your computer as markdown. Work offline, keep things private, move notes anywhere. Portable, flexible, no lock-in or account needed.
How is Moss a private notes app built for your whole life?
Most personal notes apps are either too simple or too complex. A basic notes app handles grocery lists but falls apart when life gets layered. A power tool like Notion requires setup, a learning curve, and a subscription to unlock what makes it useful. Moss is a personal notes app that sits in between: a clean, AI-organized workspace for your day-to-day life, built around privacy and simplicity. Everything in Moss stays on your computer as plain markdown files. No account required to get started, no cloud storage, no company holding your notes. A private notes app you actually own.
Can I use Moss for trip planning, budgets, and journaling?
Moss replaces a stack of disconnected tools. Plan a trip itinerary with the AI agent pulling in options and suggestions. Track a monthly budget with inline formulas that calculate automatically. Keep a daily journal in a note you revisit and build on over time. Draft a gift list, track a home project, organize your reading list. The AI agent handles the structure: organizing your notes, linking related ideas, and doing research when you ask. You stay in the document and focus on your life; Moss keeps things organized in the background.
What does it mean that Moss is a local-first notes app?
Local-first means your notes are files on your hard drive, not records in a company's database. In Moss, every note is a .md file: readable in any text editor, backed up wherever you want, and completely portable. If you already sync files with iCloud or Dropbox, your Moss notes sync automatically — no additional setup, no separate sync service required. The alternative — cloud-first apps like Notion or Evernote — keeps your notes on their servers. That's fine until you want to cancel, the pricing changes, or the company goes away. With Moss, your notes belong to you. Always. Cancel Moss and your notes are still right there, exactly as you left them.
Do I need an account or subscription to use Moss?
Download Moss and start writing. No signup screen, no email required, no trial that expires. The core notes app is free: create notes, organize them, search them, read them offline. If you want the AI agent to help with research, planning, or organization, that's where a subscription or your own API key comes in. But your notes — your actual writing — are always free and always yours. This matters for personal use. Your journal, your budget, your life plans shouldn't require a subscription to read.
How does Moss's AI help without getting in the way?
Moss's AI agent is available when you want it and invisible when you don't. Ask it to plan a weekend itinerary, calculate your monthly spending, or draft a packing list. It works inside your note, not in a separate chat window. When you're done, it's just a note — a plain file on your computer that you can edit, share, or print like any document. The agent also organizes your notes automatically: tagging related items, linking connected notes, and keeping your workspace structured without you doing any manual filing. The more you use Moss, the better it gets at keeping everything organized — without you ever having to think about it.
