Quick Start

Welcome — this page is itself a working document. Every table, chart, and diagram below renders exactly the way it would in anything you write here.

Why this isn't a chat

A regular AI chat is a feed: every reply drags the whole conversation along with it. Here the result is a document instead — AI writes into it as patches while you discuss, so by the end you have a finished piece of text, not a wall of messages to pick apart.

Your first document

• Create a document from the Documents tab in the sidebar, or just start typing in this one.
• Left pane: raw Markdown. Right pane: live formatted preview. Toggle either with Shift+Z / Shift+X, or use the panel-order button in the toolbar to see both side by side.
• Every heading gets an invisible anchor the moment it exists. That anchor is what lets a thread or an AI patch keep targeting the same section even after you edit the text around it — as long as you don't delete the heading itself.

Talking to AI: threads, patches, branches

Open the AI panel (Shift+C) and start a thread. Ask a question, or ask for a change — if AI proposes an edit, an Apply changes to document button appears under its reply. Nothing changes until you click it.

Threads branch like a forum, not like a chat log:

Want a different angle on the same section? Open another thread instead of editing the old one — nothing is overwritten, and you can always go back and read, or apply, the original.

Manual context

Click Context above the message box:

• Auto — sends the current section (or your text selection), plus whatever else looks relevant.
• Manual — you tick exactly which sections, other threads, even other documents go into this one request.

A regular chat resends its whole history on every message. Here you choose what's in the box, every time:

(Illustrative numbers, not a measured benchmark — the real ratio depends on how long your document already is.)

Keeping a document current: AI Update

The AI Update button (Shift+R) checks the web for what's changed since you last asked, and adds it — dated, sourced — without rewriting what's already there.

1. First run on a plain document restructures it into three sections: Brief (what the topic is), Description (current state), Chronology (a dated log of changes).
2. Every run after that re-checks and appends new entries to Chronology, leaving the rest untouched.
3. If a dated log isn't the right shape — you need prose, tables, charts, diagrams instead — start the document with an Editorial Approach heading. AI Update then rewrites that whole section from scratch on every run, based on the task and whatever it finds.

Version history

Open the History tab with Shift+D. Free accounts keep the last 50 versions per document — older ones drop off automatically as new ones are saved.

What you can embed

Standard Markdown — headings, bold, italic, nested lists, task lists, blockquotes, links, syntax-highlighted code — plus two extras, written as fenced code blocks just like any other:

A task list, since it's easy to miss:

• Read this guide
• Open the AI panel and ask it something
• Try Manual context on a real document

Screenshots and uploaded images aren't covered here — everything above renders from plain text, nothing to keep track of separately.

Export & import

Import accepts a plain .md file, or any of the JSON archive formats above.

Signed in vs. anonymous

No account needed to use the editor — documents save to this browser automatically. Sign in and they sync to the server instead, with autosave, so you can pick up on another device.

Who this is for

Built for tasks that need a real, substantial result — technical docs, research, deep dives, architecture decisions. Not for small talk.

That covers the surface. Nothing above is a mockup — try it right here, on this document.
