Margin Notes

Hover any highlight, click the pencil, and write a private note next to it. Like writing in the margin of a book — but on AI conversations.

How it works

Per-highlight notes

Each note belongs to one specific highlight. Click the pencil to add or edit.

500 characters

Enough for a thought, citation, or follow-up — never longer than the highlight itself.

Ctrl+Enter to save

Save with a keyboard shortcut. Esc cancels. Stays out of the way.

Visible vertical marker

A subtle orange line on the highlight tells you a note exists. Hover for preview.
