What is the difference between Pro and Ultra plans?
Pro gives you 200 prompts/day across 5 models with batch upload and save/share features. Ultra gives unlimited prompts, all 7 models, batch up to 20 images, and Text-to-Prompt functionality.
What is an Image to Prompt Generator?
An image to prompt generator is an AI-powered tool that analyzes any image and automatically produces a text prompt you can use in AI image generators like Midjourney, DALL-E 3, Stable Diffusion, or Flux. Instead of spending hours writing prompts from scratch, you simply upload a photo and let the AI reverse-engineer exactly what made that image look the way it does — capturing style, composition, lighting, color palette, and subject detail.
PromptLens is the best free ai image to prompt tool available online. Our engine supports 7 AI models and outputs prompts in 6 languages, making it the most versatile images to prompt generator for creators worldwide. Whether you need a Midjourney prompt, a Flux prompt, or a Stable Diffusion prompt, PromptLens generates optimized results in seconds.
Unlike other tools, PromptLens is completely free — no account needed to start. Just upload, select your model, and get a high-quality image to prompt result instantly. It's the fastest way to go from visual inspiration to AI-ready text prompts.
