AI Services for Writer that Solve "Illustration Creation"

Original illustrations accompanying an article can catch readers' eyes and reduce bounce rate, but commissioning an outside illustrator costs both time and money. If writers themselves can quickly turn a rough idea into a visual, it also broadens what's possible creatively. This page compares AI tools strong at illustration generation.

How does the illustration-making process change

Image-generation AI, which can produce an illustration close to your intended image just from text instructions, can dramatically cut the time needed to create an article's eye-catch image or inset illustrations. Keeping a consistent touch or character across images remains a challenge, but tools are emerging that let you supply a reference image to match style. Since copyright and commercial-use terms for generated output vary by tool, you must always check the terms of use before using it in an article.

Points for choosing an illustration-generation tool

  • How faithfully it reproduces the intended touch and mood, and how easy it is to adjust
  • Whether it can maintain consistency of character or touch across a series of articles
  • Clarity of the terms around commercial-use permission and copyright
  • Support for generation resolution and file formats suited to publishing in an article
