The document is the link.

• A letter, a spreadsheet, a presentation or a calendar is held in the address of its page
• Copy the link and you have copied the document
• Whoever has the link has the document.
• There is no account.

Take a look at some sample docs:

• A letter to the block, in the Word Processor: a title, a task list, a table that adds up, a footnote
• A talk about the document that is the link, in the Outliner
• Status, week of October 12, in the Presentation Builder: a title slide, two columns, a chart, speaker notes
• Rent, split four ways, in the Spreadsheet, with a bar chart
• Dinner at the place on Smith Street, in the Calculator: tax, tip, six ways
• How a page loads, in the Drawing Tool
• Who does what at the bakery, an org chart in the Diagram Maker
• Lift off, in the Animator
• The week of the stoop sale, in the Calendar
• A Saturday across Brooklyn, in the Trip Planner

Each link is the whole document: open it, change it, and the link in the address bar is your copy. Twenty-five more are in samples/, as files.

Private by default.

• By default nothing is kept, on your device or anywhere else.
• Your browser might save the link in history, of course. Use incognito mode if you want
• If you decide to save, it keeps your documents on your own device, never on a server.
• If you save a short link, it's encrypted with a key the server never sees.
• If you decide to use the social sharing functionality it will make a preview card and save that on a server.

Ten apps.

• Word Processor
• Outliner
• Presentation Builder
• Spreadsheet
• Calculator
• Drawing Tool
• Diagram Maker
• Animator
• Calendar
• Trip Planner

Twenty-one languages.

• Mostly the ones we speak in NYC.

Utterly fine with AI agents.

• An agent has three ways in:

1. /llms.txt for a fetch;
2. npx tinylittleoffice with a runtime (packages/doc);
3. And, for Claude Code, the skill (a short SKILL.md and a reference an app), installed with npx tinylittleoffice skill --into ~/.claude/skills.

Node 24 or later.

npm install
npm run dev      # the site at http://localhost:4178
npm test         # every test, under Node and in Chromium
npm run build    # the site as it ships

How it is made, what it protects against and how to run your own copy are in docs/: the threat model, the cryptography, self-hosting.

A security problem should be reported privately, through the repository's Security tab, never as an issue.
