What Is an AI Prompt Generator?
An AI prompt generator is a tool that transforms simple ideas into optimized prompts for AI models. Instead of manually crafting prompts, it automatically structures your input with the right format, context, and parameters - helping you get better results from AI tools without needing prompt engineering expertise.
Prompt generators work across different AI types. For text models like ChatGPT, Claude, and Gemini, they create detailed instructions and conversations. For image generators like Flux, Nano Banana, and Ideogram, they build descriptive visual prompts with style parameters. Video AI tools like Kling, Veo, and Runway also benefit from structured prompts describing scenes, camera movements, and effects.
