TrainEngine.ai
TrainEngine.ai is a browser-based image generation model trainer where you teach Stable Diffusion-style models a new subject or style with a hotword, then generate images on demand. You upload training images, pick public or private visibility, and the site handles Dreambooth-style fine-tuning plus an image generator tied to each model.
Most general image apps stop at prompting. TrainEngine.ai is built around owning a custom checkpoint: you train on SD 1.5 or SDXL, browse a public gallery of community models, and download weights as .CKPT or LoRA files for local UIs. Token packs cover training and revisions instead of a flat monthly subscription.
It fits artists, game asset makers, and hobbyists who want a repeatable visual style without running training pipelines locally. The free Trainer tier keeps public generation open while paid tokens unlock private models and heavier training runs.
