You’ve got your product name, tagline, and description tailored to your product.

2. Medical Image Analysis in Healthcare

Many people struggle to understand medical reports, whether it’s an X-ray, ultrasound, MRI, or even a blood test. These reports can seem overwhelming, especially without a medical background. That’s where LLMs can be incredibly helpful. They can provide initial insights and observations, which medical professionals can then review.

For example:

Suppose you’re looking at this medical image and want to understand the injury and how it might be diagnosed. Use this simple prompt, “Identify the injury shown in this medical image and explain how it can be diagnosed.”

Here’s the response I got:

3. Travel and Tourism: Identify locations

While scrolling through social media, have you ever come across a stunning picture and wondered, ‘Where is this place? I’d love to go here.’ Well, LLMs can help you find the location! They can analyse the image, get you the name of the place, and even help you plan your travel itinerary. Exciting, right? Let’s try this out.

Here’s an image I found on the internet, and I would like to go here sometime.

Now, I’ll just put in this prompt: “Identify the location shown in the image and create a 5-day itinerary for it. “ and let’s see what happens.

As you can see, GPT-4o not only identified the destination but also planned a travel itinerary for me.

4. Educational Tool: Understanding Diagrams and Chats

Having a teacher or guide by your side every time you need help isn’t always possible. But what if you’re stuck trying to understand a map, diagram, or chart in your textbook/course material? LLM-based image-to-text conversion can step in to help!

Imagine you’re a Class 10 student struggling to grasp the functions of the heart’s chambers, valves, and blood flow.

You upload an image of a labelled human heart diagram and type in your question. Let’s try asking it, “Explain the function of the heart’s chamber and valves and provide a simple step-by-step breakdown of how blood flows through the circulatory system.“

This way, within moments, you can receive a clear and detailed explanation that makes the concept easy to understand. If the generated response is difficult for you to understand or if you need more clarity on any of the terms, you can ask the LLM to explain further through simple follow-up prompts. Tools like LLMs make learning complex topics simpler, faster, and more accessible—right when you need it.

5. Recipe Generation through images

Do pictures of nicely presented yummy food make your mouth water? Have there been times when these images give you food cravings? You see an image of food with a beautiful presentation, and suddenly, you crave to try it, but you have no idea how to make it. Well, here’s where LLMs come to the rescue! By simply uploading the image, you can ask LLMs to identify the dish and provide the recipe to make it yourself.

For example, let’s say I want to know what these colourful biscuits are called and how to make them. Here’s the prompt I’m going to use to find that: “Identify the dish shown in the image and provide the complete recipe, including preparation steps.”

6. Accessibility for Visually Impaired Users

Visually impaired individuals are able to “see” through words – and LLMs do exactly that for them. They bring photos to life by narrating and describing visual content, transforming it into vivid, auditory experiences. For this, they first create a descriptive text of the image and then convert the text into audio.

Imagine you want to explain this photo to someone who is visually impaired. You could simply say, “Describe this image to a visually impaired person.”

With that prompt, LLMs can translate visual details into a captivating story, making the unseen tangible.

7. Identifying Plants and Diseases

Gardening and agriculture are getting a high-tech boost with the help of image-to-text conversions.

You can snap a picture of any unknown crop or garden plant, and LLMs can instantly analyse it for you. They can identify the plant, diagnose plant health, spot diseases, and even identify pest infestations. By turning visual insights into actionable text, they provide farmers and gardeners with recommendations to improve yields and ensure sustainable practices.

For instance, say you’ve got a photo of some damaged leaves. Upload it, and give the prompt “Identify the plant in the image, determine the disease it is affected by, and suggest possible remedies for its treatment.”

Just like that, you can get an analysis of the plant, the disease affecting it, and a list of treatment options—all at your fingertips. It’s like having a personal plant expert anytime you need it!

8. Virtual Customer Support in Automobile and Insurance Companies

Efficiency and accuracy are key factors in the automobile and insurance industries. To streamline claim processing, virtual customer support agents can revolutionise damage claim handling by using image-to-text conversions.

Imagine a customer is involved in an accident. Instead of contacting an insurance agent and waiting for the claim to process, the customer can simply upload photos of their damaged vehicle to a virtual customer support system. Using an LLM, the customer support team can analyse the images, evaluate the damage, and calculate the percentage of damage done—all within moments. It can even generate a detailed report to support the claim process.

Let me show you an example.

Suppose a customer needs to claim compensation for this car damage. The customer support team can simply upload this photo and prompt the LLM with a query like, “Assess the damage percentage of this car for the claim process.” The LLM will quickly evaluate the damage and provide precise insights.

With this percentage as a basis, the claim can be processed efficiently, ensuring faster settlements. By automating image-based assessments, insurance companies can reduce processing time, improve customer satisfaction, and provide accurate repair cost estimates — all with a seamless, tech-driven solution.

9. Transform Image flowchart to code files

Did you know that LLMs can generate executable code from an image in just seconds? They can analyse and extract the underlying logic from an image, explain it to you, and also show you how to build it. This saves hours of manual work and minimises errors.

For example, imagine you have an image of a transformer flowchart and need the code to execute that process. You can use a prompt like: “Analyze, understand, and describe the image. Then write the Python code to run the process shown in the flowchart.” and obtain the corresponding code.

Do try this for other images and charts. Now, let’s move to the last use case.

10. Social Media Caption Creation

Want to share those fun weekend trip pictures but not sure what to write about them? Crafting the perfect social media post can sometimes feel daunting, even for influencers who struggle to create the perfect captions and hashtags for every post. This is where image-to-text conversion becomes a game-changer, simplifying the process effortlessly.

Just upload your image, and the LLM will craft trending, eye-catching captions and hashtags tailored to your content. Whether it’s a stunning sunset, a mouthwatering plate of pasta, or a stylish outfit, this tool will ensure your posts grab attention and connect with your audience.

Let’s see how an LLM can generate the perfect caption and trending hashtags for this social media post.
