How can a new user distinguish between new and old comments?

[Andrei]

The user does not see the comment new to him or not? How to fix it? So that when adding a new comment, he sees that he hasn't read it?

Hey Andrei, Trello comments are timestamped, and are sorted by the most recent. Our comments aren't labelled to show which haven't been read yet or not, but if you're watching a card, you'll get notifications for new comments.
