In Codex desktop, save ordinary .excalidraw files in your chat workspace and reopen the same file later. Manual drawing and agent edits use that file, with stale-save protection. The hosted service supplies the editor and does not store your boards. Browser and mobile use manual file import and download; automatic chat-local saving requires desktop file support. No Whiteboard account is required. Cross-device sync and multi-user collaboration are not included.",
