CartoSketch - Turn real maps into art with AI.

Hey Product Hunt! I’m Jack, and I built CartoSketch because I kept running into the same frustration: real maps are accurate but boring, and pretty maps are beautiful but fictional. As someone who loves both geography and design, I wanted a tool that starts with real geographic data — actual coastlines, real mountain ranges, genuine street layouts — and transforms them into something visually stunning using AI. That’s what CartoSketch does. It pulls real data from Mapbox, then lets you apply styles like watercolor, hand-drawn, cyberpunk, ink wash, and more. You can write custom prompts to guide the AI, and use inpainting to refine specific areas of your map. Unlike fantasy map generators (Inkarnate, Azgaar, etc.) that create fictional terrain, CartoSketch works with the real world. And unlike Style Map Maker ($29/mo), we offer flexible credit-based pricing starting at $5. You can try it right now — every new account gets 1 free credit, no credit card required. Generate your first styled map in under a minute. I’d love your feedback on what styles or features you’d like to see next. Happy to answer any questions!
