How ChatGPT reads prompts

ChatGPT's image generation understands plain, descriptive language well, and it lets you refine results conversationally. A detailed starting prompt gets you much closer on the first try.

PromptLens writes a natural-language prompt that covers subject, composition, setting, lighting, color and mood, so you can paste it in and then ask for changes in your own words.

Tips

Example ChatGPT prompt

A cozy reading nook by a large window on a rainy afternoon: a deep green armchair, a knitted blanket, and a sleeping tabby cat. Soft gray daylight mixes with a warm floor lamp, creating gentle shadows. Muted greens and warm browns, calm and quiet mood.
