Editorial illustrations for agents

An illustrator that never breaks character.

Nib turns an idea — or a whole article — into original, white-background editorial illustrations starring an avatar you own. One image, one idea. No stock art, no prompt fiddling.

The avatar you bringYour avatar →

One chicken, seven looks. Bring any character — it stays on-model across every image.

One idea. One picture. Your character.

Hand Nib a post and it finds the load-bearing moments — the judgment, the trap, the before/after — and draws each one as a single scene. Not one image per paragraph. The ones that matter.

1

Bring your avatar

A mascot, a logo character, any avatar. It becomes the reference on every render, so your character stays on-model — forever yours.

2

Drop an idea or article

A single concept, or a whole post. Nib plans a shot list of the ideas worth illustrating and picks a look.

3

Get a consistent set

White-background 16:9 illustrations, your character performing each idea, ready to drop into the post.

Seven print looks.

One house methodology, the look is a parameter. Pick one per piece so a set reads as a series.
