Comments & Collaboration

NoteCove includes a powerful commenting system inspired by Google Docs, allowing you to add discussions directly to your notes. At the same time, NoteCove supports real-time collaborative editing — multiple people can edit the same note simultaneously with conflict-free merging.

Collaborative editing

Threaded Comments

Add comments to any text selection in your notes:

Select text you want to comment on
Click the comment icon in the toolbar or use Cmd+Shift+M / Ctrl+Shift+M
Type your comment and press Enter to post

The selected text is highlighted and linked to your comment thread.

Comment Threads

Comments are organized in threads:

Main comment: Your initial observation or question
Replies: Responses from you or collaborators
Thread resolution: Mark threads as resolved when done

Viewing Comments

Comments appear in the Comments Panel on the right side of the editor:

Click a comment to jump to the highlighted text
Click highlighted text to show its comment thread
Expand/collapse threads to manage visual clutter

Reactions

Add emoji reactions to comments for quick feedback:

Quick reactions: Common emojis for fast responses
Custom emojis: Access the full emoji picker
Reaction counts: See how many people reacted

Reactions are perfect for acknowledging comments without adding more text.

Mentions

NoteCove supports powerful @mention features that work both in comments and in your notes:

Date Mentions

Insert dates quickly using natural language:

@today - Today’s date
@yesterday - Yesterday’s date
@tomorrow - Tomorrow’s date
@date - Open date picker
@ts / @uts - Unix timestamp (seconds)
@dt - Current date and time (ISO 8601)
@udt - Current UTC date and time

All dates appear as clickable chips and resolve to YYYY-MM-DD format.

User Mentions

Mention people in your notes and comments:

Type @ to see suggestions
Select a person from the list
Click mentions to see profile details
Search for all mentions of a person

To be mentionable, set up your @handle in Settings.
