Build structured image-generation prompts without memorizing technical photography vocabulary. Describe your scene, subjects, environment, and action in plain text, then fine-tune the look by selecting from seven visual categories: camera angle, lighting, camera equipment, framing, style, mood, and color grading. Each category offers curated presets and individual options with plain-English explanations so you understand what every setting does. Configure lighting with multiple sources and roles (key, fill, accent, practical, ambient). Exclude unwanted elements with a negative-prompt field. The tool assembles everything into a structured JSON prompt ready to copy and paste into any AI image generator.
TonniTools is built to run locally in your browser. Since no data ever leaves your device, everything works, even without internet.
Your main prompt. Focus on the contents and dynamics of the scene. Use the sections below for more precise definitions.
The scene can be described entirely in the summary, or add structured subjects for more precise control.
The overall environment. Describe ground, sky, horizon, distance, or anything else about the setting here. The slots below let you describe specific depth layers precisely.
Comma-separated. Positive framing (eg. 'empty street') often beats negatives (eg. 'no cars'), but Gemini's JSON exclude slot handles negatives well.
