# Autosave and undo
> How your work is saved, what undo covers, and what it does not.
## There is no save button
The canvas saves itself. Changes are batched and written after about 1.5 seconds of inactivity, and
at most 3 seconds during continuous editing.
A status capsule at the top left shows where you are:
| Status | Meaning |
| --------------- | ------------------------------------------- |
| **Pending** | Changes are queued |
| **Saving** | Being written |
| **Saved** | Everything is stored |
| **Save failed** | Something went wrong — do not close the tab |
Closing the tab or leaving the canvas forces a final save first.
## Undo has limits worth knowing
Undo holds **40 steps**, lives **only in the current session**, and is **cleared when you switch
canvases**. Reloading the page empties it.
More importantly, undo does not cover everything.
Moving nodes · Resizing · Resizing a text window · Aligning · Deleting nodes · Deleting a
connection · Making a connection · Setting a color tag · Editing text · Editing an annotation
Creating a node · Pasting · Duplicating · Uploading · AI generation results · Creating a group ·
Creating or deleting a canvas
The practical consequence: if you paste twenty nodes by accident, `⌘Z` will not take them back. You
have to select and delete them — and *that* deletion is undoable.
`⌘Z` undoes, `⌘⇧Z` redoes (`Ctrl+Y` also works on Windows). The viewport control bar has buttons for
both.
## Real-time sync
Canvases sync between people working on them. Incoming changes from teammates are applied to your
board without a refresh.
WJI holds an incoming change back briefly if you are mid-interaction, and ignores the echo of your
own writes, so a teammate's edit does not interrupt a drag you are in the middle of.
There are no presence indicators — no cursors, no avatars, no highlight showing what a teammate
has selected. You see the results of their edits, not their pointer.
## What is not stored
Undo history and your current selection are session-only. Viewport position, performance mode, and
panel widths are remembered locally in your browser, per canvas.
