Text-to-image generators and AI design studios that turn prompts, sketches or reference photos into illustrations, photos, product shots and concept art, and often extend into editing, upscaling and video. Options range from single-model services with a recognizable look to hubs that bundle dozens of third-party models, plus raw APIs for developers. When comparing, check how well each one renders text, how much control it gives over references and style, whether outputs are cleared for commercial use, and how credits or GPU time are counted.
