Offline Mode

Most documents are saved to livediagram's servers so you can reach them from any device and share them. Offline Mode is the opposite choice: a document saved only in the browser you made it in, that never touches the server at all. It suits private, local-first work, or simply wanting a document that physically never leaves your machine.

Creating an offline document

Offline Mode is off by default and chosen per document, so you can keep normal documents and offline ones side by side.

• On the New document screen, step through the wizard to the Location step (the third step, after Template and Theme) and choose Local Browser under Save location, then click Create.
• The document is written to your browser's local storage and opens like any other. A Local only badge next to its name in the editor, and the matching Local only pill wherever it is listed (Explorer lists and cards, search results, the Explorer panel and the Trash), mark it so you always know which documents are local-only. Hover or focus the pill to read that the document lives only in this browser and that clearing this browser's site data deletes it; click it to come back to this guide. The Explorer sidebar's This browser row lists them all.

What's different

An offline document is a normal document: every editor feature works, including shapes, arrows, layers, tabs, themes, undo/redo, and export. Only the features that need the server are unavailable, because there's no server copy to power them:

• Sharing needs a document on the server, so opening Share on an offline document prompts you to sync it to your account first. Embeds are unavailable for the same reason.
• Live collaboration and teams don't apply; an offline document is yours alone.
• The AI assistant works while you're online (it reads your current canvas), but not with no connection.
• Images you add are stored inside the document, so it stays fully local.

Moving to and from your account

You can change your mind at any time, from the document's menu in the Explorer.

• Sync Document uploads an offline document to the cloud. It becomes a normal document, shareable and reachable from your other devices, and the local-only copy is removed.
• Take Offline does the reverse: it downloads a cloud document into this browser and then removes it from your account and every other device. Because that deletes the server copy for good, we ask you to confirm first.
• A tab it shares with other documents (see Add a Tab to Another Document) stays in those documents, and this browser keeps its own copy. From then on the two are separate: edits on one side no longer reach the other, and syncing the document back brings your copy in as a new tab beside the original.
