Your first comment

Leave one

Select a passage in a note, right-click it, and choose Add comment. The composer opens with the selected text quoted at the top.

The composer is Obsidian’s own markdown editor, so Cmd+B, list continuation, [[ autocompletion and live preview behave the way they do in a note. Write the comment as markdown; there is no plain-text mode, because the sidebar renders it as markdown too.

Submit, and three things happen: the comment appears in the right sidebar, the passage gets an underline in the editor, and a † appears at the end of it.

Propose a rewrite

Suggest an edit in the same context menu opens the composer with a suggestion block already inserted, prefilled with the quoted passage and selected, ready to be typed over:

The relative clause is doing no work here.

```suggestion
The horse bolted.
```

The card renders that as a word-level diff against the quoted passage, with an Apply button in its header. Applying splices the block’s contents over exactly the quoted range and resolves the comment.

Answer one

Click a card to scroll the editor to its passage. Reply opens the same composer under the comment; a reply can carry a suggestion block of its own, so a counter-proposal is an ordinary reply.

Resolve greys the card out and drops the comment from the open count. It stays in the list, and its passage stays underlined. Resolving is not hiding.

Where it went

Open the note’s frontmatter in source mode and it is all there, under one obelisk key. That file is the whole database.
