Create one
In the Library, select + and pick New Live Document. Rheos creates the document as Untitled Document and opens it straight away atdashboard.rheos.app/docs/....
On a phone, a live document opens as a read-only viewer: the title and the text, with a back
link to the Library. To edit it, comment on it or use its assistant, open it on a larger screen.
Write
Select the title at the top of the document and type to rename it, then write in the body below.- The formatting toolbar sits in the middle of the header: bold, italic, strikethrough, two heading levels, bullet and numbered lists, a quote block, a divider, and undo and redo.
- Type
/anywhere in the body for a block menu. Ask Rheos AI is the first item — it asks Rheos to carry on writing from what’s already in the document. Below it: Text, Heading 1, Heading 2, Bullet List and Numbered List. - Two panel buttons in the top right hide and show the side panels. The right-hand one is the panel that does the work — it holds comments and chat. Worth collapsing on a small screen.
Auto-save
Auto-save is on by default — the toggle is in the header. With it on, Rheos saves a couple of seconds after you stop typing and confirms with a Saved message. Turn Auto-save off if you’d rather save deliberately. Save Changes in the header saves on demand either way, and with auto-save off, selecting Library with unsaved work raises an Unsaved Changes prompt offering Discard or Save & Exit.Comments
Select any text in the body. A Comment button appears above the selection — select it, write your note in the Add Comment box, then select Add Comment. Rheos records the text you highlighted and the section it came from. Comments stack in the right-hand panel under Comments, with a count of the open ones. Each has Resolve, and you can Unresolve it later. Delete appears on comments you wrote.The document chat
The right-hand panel has a second mode. Open the settings icon at the top of the panel, then pick Chat Mode under Sidebar Mode — Comments Mode switches back. Ask for an edit in plain language, for example “tighten the second section” or “add a short intro”. The input area at the foot of the panel stacks three things, top to bottom:- A button that sends every unresolved comment at once, labelled with the count — so Apply 3 comments when three are open. It only appears when there are unresolved comments.
- The Brand context switch, directly above the text box. It controls whether Rheos brings your brand identity into the edit, and it’s on by default.
- The text box itself, with the send button beside it. Enter sends; Shift-Enter starts a new line.
Reviewing the changes
Nothing is written into the document automatically. Every edit comes back as Review Changes, a grouped diff that takes over the panel until you finish with it:- Accept or reject each group with the tick and cross.
- All accepts every group at once; None rejects every group at once.
- Apply Changes stays greyed out until every group has been decided — the counter beside it (2/5 decided) tells you how many are left. Accepting a couple and leaving the rest untouched won’t unlock it; use All or None if you want to move fast.
- Apply Changes then writes your accepted groups into the document. Cancel discards the whole edit and puts the document back as it was.
