With the rapid development of AI, there are now many tools available that can generate images from prompts.
Sometimes, you might come across particularly stunning images, especially those created by others using AI.
When you want to create similar images yourself, some good websites might list the related prompts.
However, more often than not, you have to ask the creators directly and hope they respond.
But don’t worry! I’ve compiled a list of free image-to-prompt tools that can help you quickly convert images back into their original prompts. I’ll also review each one to determine which is the best.
Let’s Start.
Writingmate AI
Although this is an AI writing website, it also offers a completely free image-to-prompt service. I tested it four times, and it seems the service is entirely free and doesn’t require to signup.
The generated prompts can be directly copied, making it easy to paste them into AI image generators.
To test the effectiveness of the prompts, I used the generated prompts from the original images in Genzone AI’s AI Image Generator to create the same anime effects for comparison.
Original Image:
Generated Prompt:
“A young woman with a bob haircut sits in a train compartment, gazing directly at the camera. She wears a fitted white V-neck top and denim shorts, exuding a confident yet serene demeanor. Soft natural light filters through the window, creating a calm atmosphere. The background features blurred reflections of other passengers, enhancing the sense of a quiet moment in transit.”
Original Images VS AI Images from Generated Prompts:
Test some NSFW images and the prompts it generates:
“Create a high-fashion editorial featuring a model in delicate white lace lingerie, standing against a soft white backdrop. Capture a natural and elegant pose that highlights her confident expression and toned physique. Focus on lighting that enhances the lace’s intricate details, while keeping the overall aesthetic refined and artistic.”
Pros:
• No signup required
• Completely free
• Supports various formats like JPEG, PNG, and WEBP
• Prompts can be copied with one click
• Support NSFW Prompts
Cons:
• Generated prompts are inconsistent, leading to unstable results
Cococlip AI
This website also offers a free Image to Prompt generation service. It’s completely free, requires no registration, and supports various image formats.
Generated Prompt:
“The image is a portrait of a young woman sitting on a train. She is wearing a white t-shirt with a plunging neckline and blue jeans. Her hair is styled in a shoulder-length bob with bangs and she is looking directly at the camera with a serious expression. The background is blurred, but it appears to be a train with other passengers visible through the windows. The overall mood of the image is serious and contemplative.”
However, there are some problems with the generated prompts. For example, the original image of the young woman was sitting in a bus, not in a car, and the atmosphere wasn’t very serious.
I placed the generated prompt into Genzone AI’s Image Generator.
Let’s test some NSFW images by generating prompts and then putting them back into Genzone AI’s AI Image Generator:
Generated Prompt:
“The image is a portrait of a young woman posing in a white lingerie set. She is standing in front of a plain white background and is looking directly at the camera with a serious expression on her face. The woman is wearing a white bra and matching thong with a floral pattern. Her hair is styled in loose waves and falls over her shoulders. She has a slight smile on her lips and her body is toned and fit. The overall aesthetic of the image is sensual and feminine.”
Pros:
• No signup required
• Free
• Supports various formats like JPEG, PNG, and WEBP
• Can create similar image with one click (but it’s not free)
• Can generate NSFW prompts.
Cons:
• Need to queue after using twice
• Takes long time to generate prompts
• Sometimes prompts are not very consistent with image
Videotok AI
Videotok is an AI video tool website that also offers a free image-to-prompt tool.
However, I noticed that it only allows 3 free trials per day, and the image size is limited to 1024 x 1024 pixels.
Let’s see how effective it is.
Generated Prompt:
“Photorealistic portrait of a young Asian woman with short, dark brown hair, wearing a low-cut white v-neck t-shirt, sitting on a dark gray bus seat, soft natural lighting, 8k resolution, cinematic lighting, sharp focus, detailed textures.”
The Image of this Prompt Generated by Genzone AI:
Overall, the prompt captures the main elements of the image but misses many details, such as the person’s physique and expressions.
Let’s test some NSFW images and their prompts:
“A stunning portrait of a young woman with long, dark brown hair, wearing a delicate white lace lingerie set. The image is shot against a clean white background, emphasizing the model’s beauty and the intricate details of the lingerie. The lighting is soft and diffused, creating a sensual and intimate mood. High resolution, 8k, photorealistic, detailed, soft focus, cinematic lighting.”
Pros:
• Free
• No sign-up required
• Prompts accurately and thoroughly describe the environment and atmosphere
Cons:
• Limited to three uses per day
• Image size cannot exceed 1MB
• Prompts lack many details about the person
ImageToPrompt
This website is very simple and easy to use. It is free to use without registration. It supports image formats like PNG, JPG, and HEIC, with a maximum upload size of 4MB.
The biggest advantage of this website is that it can generate prompts suitable for both Stable Diffusion and other AI image generators simultaneously.
SD 2 Prompt
there is a woman sitting on a bus with a white shirt, beautiful asian girl, japanese model, beautiful japanese girls face, girl cute-fine-face, asian girl, beautiful asian woman, cleavage, low cut top, young sensual gravure idol, white bra, realistic young gravure idol, japanese goddess
SD XL Prompt

Description (Alt Text)
A close-up portrait of a young woman with shoulder-length brown hair, wearing a white V-neck shirt. She has a neutral expression and is looking directly at the camera. Soft natural light illuminates her face, highlighting her features, including her full lips and natural makeup. In the background, a blurred figure can be seen, suggesting a public transport setting. The overall mood is calm and introspective.
However, the generated Stable Diffusion prompt does not match the original image. Therefore, I will use the final general text for testing.
We can test NSFW Images to prompts again:
SD 2 Prompt
“arafed woman in a white bikini and panties posing for a picture, white bra, model with attractive body, posing in bra, 2 4 year old female model, sexy girl, attractive body, sexy body, sexy young woman, sultry body with sexy belly, beautiful body and face, perfect face and body, translucent body, beautiful feminine body, beautiful woman body“
SD XL Prompt
“a beautiful young woman in a white lingerie and underwear posing for a photo shoot, beautiful woman body, model with attractive body, white bra, attractive face and body, sexy body and face, beautiful shape of face and body, attractive body, beautiful body and face, beautiful feminine body, wearing sexy lingerie, beautiful precise face and body, symmetrical body, perfect symmetrical body, perfect body, perfect body and face, perfect female body, posing in bra, beautiful body, fit body, white body”
Description (Alt Text)
“A young woman with wavy, shoulder-length hair poses confidently against a plain white background. She wears delicate, sheer white lingerie featuring floral embroidery, comprising a triangular bra and matching thong. Her expression is serene, highlighting her natural beauty. The soft lighting accentuates her toned physique and smooth skin.”
We can see that the prompt does a good job of capturing the appearance, physique, but it does not capture the surrounding environment of the person in the image.
Pros:
• No registration required
• Completely free
• Consistent prompt generation
• Support NSFW prompts
Cons:
• Generated prompts do not match the images
Conclusion
Although many related tools can be found on Google, I excluded all websites that require registration for this review.
Among the four, Writingmate AI is the best. While it doesn’t have many additional advantages, it has the fewest drawbacks.
