When a drawing needs a familiar symbol — a gear, a cart, a star — there is no need to draw one. Ask for it in the chat, and the assistant searches over 200,000 open-source icons, shows you a choice, and puts the one you pick into your drawing as plain SVG.
Opens a button with room on its left. Sign in for free, then ask "add a gear icon to the left of the text".
Icon search is one of the assistant's tools rather than a separate screen, so you ask for an icon the way you would ask for any change. It searches the open icon sets behind Iconify — Tabler, Lucide, Material, Font Awesome, Phosphor, Fluent and many more — and shows up to 30 matches, a different set's take on each where it can.

Only icons whose licence asks for no attribution are offered — MIT, Apache 2.0, ISC, BSD, the Unlicense and CC0 — so what you insert can be used anywhere without a credit line. The icon goes in as SVG markup, not a link, so the drawing does not depend on anything outside it.
Yes. Only icons under licences that allow use without attribution are offered.
Ask for more icons, describe it differently, or choose "None — generate instead" to have the assistant make a picture of it.
