🤫 21+ Practical AI Secrets That 99% Of People Don't Know About

Have you been using ChatGPT and other AI tools but feel like you're not using their full power? You are not alone. Most people only use the very basic features of these great tools. Today, we will look at 21+ practical and creative ways to use AI that can help change your daily life, your work, and how you make decisions.

Whether you want to redesign your living room, spot scam messages, or even win geography games, these AI uses will show you how strong and easy to use artificial intelligence has become. Let's look at these useful tips that you can start using right now.

Creative And Design Uses

1. See Your Dream Room Before You Buy Furniture

You don't have to wonder anymore if that new sofa will look good in your living room. With AI image tools, like the image editing feature in Gemini, you can see exactly how your room will look with different furniture.

Here’s how you can do it:

1. Take a photo of your empty room.

   

2. Upload the picture to an AI tool and describe what each color means.

3. For example, you can write a prompt like this:

   Example Prompt: 

"This is a photo of my living room. In the green area, please put a dark gray L-shaped sofa. In the red area, please put a round coffee table made of light wood. In the purple area, please put a cream-colored fuzzy rug. On the wall, please hang an abstract painting with blue and yellow colors. I want the room to feel modern and cozy."

The AI will create a very real-looking image, showing you exactly how your room will look with all these items. The results are usually very accurate and can help you avoid buying expensive furniture that you might regret later. You can also use this for fashion – upload a photo of yourself and ask the AI to show you how you would look with purple hair, new glasses, or different clothes.

2. Make History Come To Life

Have you ever wondered what old buildings looked like when they were new? AI can help you see these historical places as they were many centuries ago.

Take a modern photo of ruins like the Colosseum in Italy or Angkor Wat in Cambodia, and ask the AI to create a realistic picture of how these places looked in their best time. You can add specific details to make the scene feel more alive.

Example Prompt: 

"This is a picture of the Parthenon in Athens, Greece, today. Can you recreate this image to show what it looked like in the year 438 BC? Please show the temple as complete, with all its statues and a full roof. Around the temple, please add people of Athens in old-style clothes, walking around and attending a ceremony."

The AI will study the history and create beautiful pictures, complete with the right clothes, activities, and feeling for that time. This is a great way to learn history in a fun and visual way.

3. Turn Your Product Ideas Into 3D Designs

You don't need to learn difficult 3D software like Blender anymore. Now, you can turn your simple drawings on paper into professional-looking 3D product designs.

Follow these steps:

1. Draw your product idea on paper (even a messy drawing is okay).

   

2. Take a picture and upload the image to an AI tool.

   

3. Ask the AI: "Please create a 3D model of this product based on my drawing. I want it to have a simple design and look like it's made of recycled aluminum."

   
   

4. You can ask for different views: "Now, show me this product sitting on a wooden desk."

   
   

5. Make changes by saying things like: "Make the bottom part a little thicker and add a small logo in the corner."

   
   

This is perfect for people with new business ideas, inventors, or anyone who wants to see their idea come to life before spending money to create a real sample.

4. Create Professional Background Visuals For DJs

Those amazing, colorful 3D moving images you see at concerts and DJ shows? They are surprisingly easy to make now.

You can use AI video tools like Kaiber to create looping visuals. You just need to describe what you want.

Example Prompt: 

"Create a perfect 15-second looping video for a DJ background. The video should have an abstract, outer-space style, with tunnels of neon light in blue and purple moving slowly to an electronic music beat. Make sure the video loops smoothly without a jump."

The AI will create seamless video loops that can play behind a performance without any awkward cuts.

5. Design Professional Business Cards And Marketing Materials

Easily turn your logo or brand ideas into a complete set of marketing materials.

Upload your logo and ask the AI.

Example Prompt: 

"Use the logo I uploaded to create a business card design. I want the card to look classy and simple. Put the logo in the top left corner. Use a clean, easy-to-read font for the name, job title, and contact information (email, phone number). The background should be white or light gray to look professional."

After that, you can ask for other things like a social media banner or a t-shirt design, all while keeping your brand style the same.

6. Convert File Formats

Do you need to change a JPEG file to a PNG file or other file types? ChatGPT can write the code to do this for you.

Just upload your file and say, "convert this file to a PNG with a transparent background." The AI will create the code you need and give you a download link for your converted file. This is very helpful for designers or people who work with many types of media files.

Business And Work Uses

7. Detect Scams And Phishing Attacks

This is maybe one of the most valuable uses of AI – protecting yourself and others from fraud.

For emails: Copy and paste suspicious emails into ChatGPT and ask: "Is this a real offer or a scam email? Please analyze it for me." The AI will look at the content, check for common scam signs, and even research the companies mentioned to see if they are real.

Example Prompt for an email: 

"I got this email saying my bank account is locked and I need to click a link to verify. Here is the email text: [paste the email content here]. Is this a scam? Please show me the suspicious signs."

For text messages: Paste suspicious text messages and get a quick analysis of whether they are scams.

Example Prompt for a text message: 

"I got this message: 'Congratulations! You have won an iPhone 15. Please visit [strange link] to claim your prize.' Is this real?"

This is especially helpful for older family members who might be targets for scammers. Show them how to use this feature for any message they are not sure about.

8. Analyzing If Solar Panels Are A Good Idea

Thinking about getting solar panels? AI can do a full study for you.

Upload an image of your house from Google Maps and ask:

Example Prompt: 

"Please do a study about installing solar panels at this address. Based on the satellite image of my house, please estimate the cost, how much money I can save on my electricity bill each year, and analyze if my roof direction and any shade from trees will be a problem. My location is in District 2, Ho Chi Minh City, Vietnam."

The AI will:

• Find your location and local electricity prices.

• Analyze your roof's direction and any potential shade problems.

• Research local solar companies and their prices.

• Calculate how much energy you can produce based on the sun in your area.

• Tell you how long it will take to get your money back from savings.

9. Automatic Task Scheduling

Set up ChatGPT to send you regular updates on topics you care about.

Example Prompt: 

"Please create a repeating task for 8:00 AM every morning. This task is to find the 3 most important technology news stories from major news sites and summarize each story in 3 sentences. Then, email the results to me."

The Result:

{
  "title": "Send Daily Tech News Summary",
  "prompt": "Find the 3 most important technology news stories from major sites and summarize each in 3 sentences, then email the results.",
  "schedule": "BEGIN:VEVENT\nRRULE:FREQ=DAILY;BYHOUR=8;BYMINUTE=0;BYSECOND=0\nEND:VEVENT"
}

You will get professionally formatted emails with the latest news, helping you stay informed without needing to check many websites. You can manage these schedules in the settings of ChatGPT.

10. Team Meeting Coordinator

Is it hard to find a meeting time that works for everyone? AI can solve this problem instantly.

Copy and paste everyone's available times (from Slack, email, etc.) into ChatGPT and ask:

Example Prompt: 

"Here are the available times for 4 people on my team next week:
Ann: Free Monday (9-11 AM), Wednesday (2-5 PM)

Ben: Free Monday (10 AM-12 PM), Tuesday (all day)

Cindy: Free Monday (9-10 AM), Wednesday (3-5 PM)

Turn messy whiteboard notes or handwritten notes into organized documents.

Upload a photo of your notes and ask.

The AI will:

• Type out all the text correctly.

"Based on the customer data I uploaded, please write an SQL query to find all customers who live in 'Hanoi', have made a purchase in the last 6 months, and have spent more than 5,000,000 VND in total."

The AI will generate clean, working SQL code that you can use in your database system.

SELECT 
    c.customer_id,
    c.name,
    c.city,
    SUM(o.total_amount) AS total_spent,
    MAX(o.order_date) AS last_purchase_date

    AND o.order_date >= DATE_SUB(CURDATE(), INTERVAL 6 MONTH)
GROUP BY 
    c.customer_id, c.name, c.city
