Question: Do you know of a service that allows me to design my own puzzle with custom artwork and piece count?

If you want to create a custom puzzle with your own art and specific number of pieces, PuzzleGenerator could be a good fit. This AI-powered service lets you generate custom jigsaw puzzles based on text prompts, with a range of puzzle sizes (110, 252, 500 or 1014 pieces) and styles. The puzzles are made with high-quality chipboard pieces, bright sublimated print and sturdy paper boxes. It's good for casual puzzle buyers and artists who want to turn their ideas into reality.

If you need a broader range of creative tools, Artiphoria is an AI image generation service that can create original artistic content. It's aimed at a variety of industries, but its ability to create digital art on the fly with more than 120 visual styles could be useful for creating custom puzzle art. The service offers a range of pricing levels and a 7-day free trial to let you try it out.

If you want a more general purpose image generation service that can handle high-quality visual assets, Leonardo could be of interest. It's for creators and teams, with abilities like image generation, an AI Canvas for editing, and 3D texture generation. It's not specifically designed for puzzle creation, but you could use its abilities to create detailed and elaborate puzzle art.
