Create Custom Illustrations

Generate unique illustrations for websites, apps, and marketing materials in any style from flat design to watercolor.

Quick answer: Use the Generate Image tool through ToolRouter to create custom illustrations directly from Claude, ChatGPT, Microsoft Copilot, and OpenClaw — connect once, then drive it with plain-language prompts. No code required.

Tool

Generate Image

Custom illustrations give brands a distinctive visual identity, but commissioning them from illustrators is expensive and time-consuming. AI image generation makes it possible to create unique illustrations in any style — from flat vector-style graphics to detailed watercolor scenes — in seconds.

ToolRouter's text_to_image skill supports a wide range of illustration styles. Describe the subject, choose your artistic style, and specify colors to match your brand. Use edit_image to refine specific elements without regenerating the entire illustration.

This is transformative for SaaS companies needing onboarding illustrations, publishers creating book and article visuals, educators developing learning materials, and any brand that wants a unique visual language without the cost of custom illustration work.
