How saving works

None of the three editors has a Save button you are required to press. All of them write on a short debounce after you stop typing.

What the indicator next to the title means:
• "Saving…" — a write is in flight right now.
• "Saved <time>" — everything you have typed is stored, as of that time.
• An error message in its place — the write failed. The text is still in the editor; check your connection and make one more edit to retry.

Practical notes:
• Wait for "Saved" before closing the tab on a burst of edits — the debounce is short but it is not zero.
• Two people can edit the same deck at once and see each other's cursors. For docs and sheets, avoid two people in the same file at the same time; last write wins.
• Because saves are continuous, there is no "unsaved changes" prompt to rely on. If you want a checkpoint before a risky rewrite, duplicate the file first.
