🎨 AI Image Generator

Free, unlimited, uncensored AI image generator - no signup, no watermark

About this tool

A free AI image generator with no limits and no filters: type any prompt, generate as much as you like and never hit a paywall. Start with your idea (e.g. "Cat on the table"), then stack ready-made looks on top - subject, colour mood, framing and camera/optics presets. Each look is a short English phrase added to your prompt, so the same idea can become a warm portrait at 85mm or a cold wide landscape on vintage film. Uncensored and unlimited, no signup and no watermark. Finish with optional colour correction - pick a colour grade and fine-tune it with simple sliders - then download your image.

Describe the image, then pick a subject if you like. Each tag is glued to your prompt as a short English phrase.

Write it in English for the best results. Everything you pick below is appended to this.
What kind of picture it is.

API

POST /api/tools/image-generator/run (multipart/form-data) → JSON with outputs[].url, a zip link and a config_url.

Every run also hands you the config JSON (button above). It is the request body - POST it straight back to replay the exact generation:

curl -X POST -H 'Content-Type: application/json' \\
  --data @genbox-config-image-generator.json \\
  /api/tools/image-generator/run
