I just created 5 apps using GPT-5 and it's so easy it feels like it should be illegal — here's how to do it
In other words, natural language is the new programming language, and you're no longer limited by your coding skills (or lack thereof) to go from concept to functional prototype in just a few minutes. During the live stream of the GPT-5 model's launch, Sam Altman and his team made coding look way too easy. As someone who did poorly in computer science class in college, I decided to put ChatGPT-5 to the test.Here's what happened when I took five totally different app ideas, from a meme generator to a personal wellness journal, and asked ChatGPT-5 to build them from scratch. No coding. No wireframing. Just clear descriptions and a few follow-up questions.
The results were wild. I created five working apps in less than 30 minutes — total! Complete with mobile builds, custom icons and working UI logic, the apps I developed were available in lite form (web only) and ready for mobile. Had I wanted, I could have used outside software and formatted them to be sold in the app store.
While that might be next, here's a look at how it all works, what I built and why GPT-5 may have just changed how we develop software forever.
MoodMate helps you process your feelings by turning quick notes into short reflections, complete with calming tips like breathing exercises. You type how you're feeling, and the AI responds with thoughtful insights to help you reset and reflect. It's like journaling, but with a built-in emotional coach and it takes less than a minute.
Enter whatever ingredients you have on hand (even the random stuff) and SnackStack spins up three recipes you can actually make. Whether you've got eggs, spinach and hot sauce or just pasta and ketchup, this app finds a way.
As a parent, I've been thinking about this one for a while. It's great this app is on mobile (and not just desktop) for story time on-the-go. Let your child choose a character, setting and lesson the story will teach. Then, watch as StorySpark generates a one-of-a-kind bedtime tale. It even reads the story aloud using your device's speech function.
Get instant access to breaking news, the hottest reviews, great deals and helpful tips.
TaskTamer takes your big goal (write a novel, launch a side hustle, train for a 5K) and breaks it into weekly action plans. Just tell it your goal, timeline and how much time you can commit. It turns ambition into a step-by-step roadmap you can actually follow.
Upload any image and MemeMachine instantly suggests six funny captions, complete with that classic meme-style formatting. You can tweak the text, move it around and download a ready-to-share meme in seconds. It's humor-on-demand with zero Photoshop skills required.
The fastest way to test or share your app is to create a standalone HTML file. During the testing process, I created several different apps and immediately tried them by doing this version because you can quickly test the app by running it locall (no installs). Running the app in your browswer uses mock AI output for demoing and stores everything in your browser with localStorage This is perfect for user testing, internal previews or when mobile device setup isn't an option (e.g., slow Expo Go connections, locked-down Wi-Fi networks).Go this route if you just want to see your app in action and plan on only using it on your computer.
If you think your app is so good that you want to upload to the Apple app store or Google Play, then this is the route for you. However, keep in mind there are a few extra steps. You'll need the following:
For these tests, I created each app in the following versions:
Same prompt. Same UI logic. Two completely different platforms. That's the power of GPT-5. All you need to do is describe your idea once and once it's built, you can deploy your app in any form, anywhere.
If you are stuck with any of this because you have no idea where to start. Don't worry, GPT-5 will walk you through everything. You can upload screenshots or ask your questions directly and it will troubleshoot the entire process until you get your app uploaded to the app store of your choice.
The leap in simplicity comes from three things:
When I first started creating my apps and GPT-5 started throwing words at me like "localStorage," "Expo Go," and "download folder location" (okay, I knew that one), I wondered if any of this was worth it. So, when I got frustrated I let the AI know. It responded by telling me it would "go slower" and that it was "here to help every step of the way." That was reassuring even though I was still feeling like my minimal coding skills would never allow these apps to come to fruition. But, GPT-5 urged me to stay the course and since it has the patience of a non-human, we were in it to win it. Ultimately, generating five ready-to-use apps.
GPT-5 turns app building into something as easy as writing an email. You describe what you want, it creates a prototype. You tweak the tone, logic or UX in plain English, and it rebuilds it.
The hardest part isn't the coding anymore, it's coming up with the ideas, which GPT-5 can help with, too. So if you've ever said 'I wish there was an app that…' — guess what? There can be. In about five minutes.

The Radical Changes AI Is Bringing To Higher Education
From the printing press to typewriters to personal computers to the internet, technology has been instrumental in reshaping higher education over the past 500 years. At the same time, much of that reshaping has been closer to the edges rather than a complete upheaval. Artificial intelligence has the potential to transform and redefine higher education at its core, and will likely do so in the next year. Using a modified quote from ChatGPT, AI is coming to higher education like a squirrel on espresso! As with other industries, AI is set to redefine higher education, for better and worse. Here is a select set of areas that will be impacted: In all, AI-integrated higher education has the potential to hold much promise. Of course, the potential has already been met with a backlash. Similar to the church's reaction to the printing press, higher education institutions are spending a disproportionate amount of time attempting to limit the use of AI, assuming the current educational model should go unchallenged and unchanged. Rather than covering one's ears, the key will be to limit the potentially ineffective aspects of AI by opening up the higher education enterprise (e.g., open-source the educational approach to ensure adequate critique). If done well, AI can revolutionize higher education for the better.

Did a Human Write That? Detect AI Writing With These Tips
AI has exploded in popularity over the last few years, thanks in no small part to large learning models like ChatGPT. As AI has evolved, it's become an easy way to whip up emails, and for students to write their assignments. The days of paying someone else to write their essay are over, when there are AI writing tools that can do the deed in mere moments. As a professor of strategic communications, I encounter students using AI tools like ChatGPT, Grammarly and EssayGenius on a regular basis. It's usually easy to tell when a student has used one of these tools to draft their entire work. The telltale signs include ambiguous language and a super annoying tendency for AI to spit out text with the assignment prompt featured broadly. Don't miss any of CNET's unbiased tech content and lab-based reviews. Add us as a preferred Google source on Chrome. How to tell if it was written by AI Some of the most common ways to tell if something was written using AI are: Key terms from your assignment prompt are used repeatedly. Inaccurate facts are included, thanks to the AI chatbot hallucinating. Sentences don't sound natural. Explanations are generic and repetitive, rather than actually leading anywhere. The tone doesn't sound like their usual writing style. For example, a student might use ChatGPT -- an AI chatbot that uses large language model learning and a conversational question and answer format to provide query results -- to write a short essay response to a prompt by simply copying and pasting the essay question into the tool. Take this prompt: In 300 words or fewer, explain how this SWAT and brand audit will inform your final pitch. This is ChatGPT's result: Screenshot by Rachel Kane/CNET I have received responses like this, or those very close to it, a few times in my tenure as a teacher, and one of the most recognizable red flags is the amount of instances in which key terms from the prompt are used in the final product. Students don't usually repeat key terms from the prompt in their work in this way, and the results read closer to old-school SEO-driven copy meant to define these terms rather than a unique essay meant to demonstrate an understanding of the subject matter. But can teachers use AI tools to catch students using AI tools? I devised some ways to be smarter in spotting artificial intelligence in papers. Catch AI cheaters Here's how to use AI tools to catch cheaters in your class. Understand AI capabilities There are AI tools on the market that can scan an assignment and its grading criteria to provide a fully written, cited and complete piece of work in a matter of moments. Some of these tools include GPTZero and Smodin. Familiarizing yourself with tools like these is the first step in the war against AI-driven integrity violations. Do as the cheaters do Before the semester begins, copy and paste all your assignments into a tool like ChatGPT and ask it to do the work for you. When you have an example of the type of results it provides specifically in response to your assignments, you'll be better equipped to catch AI-written answers. You could also use a tool designed specifically to spot AI writing in papers. Get a real sample of writing At the beginning of the semester, require your students to submit a simple, fun and personal piece of writing to you. The prompt should be something like "200 words on what your favorite toy was as a child," or "Tell me a story about the most fun you ever had." Once you have a sample of the student's real writing style in hand, you can use it later to have an AI tool review that sample against what you suspect might be AI-written work. Ask for a rewrite If you suspect a student of using AI to cheat on their assignment, take the submitted work and ask an AI tool to rewrite the work for you. In most cases I've encountered, an AI tool will rewrite its own work in the laziest manner possible, substituting synonyms instead of changing any material elements of the "original" work. Here's an example: Screenshot by Rachel Kane/CNET Screenshot by Rachel Kane/CNET Now, let's take something an actual human (me) wrote, my CNET bio: Screenshot by Rachel Kane/CNET The phrasing is changed, extracting much of the soul in the writing and replacing it with sentences that are arguably more clear and straightforward. There are also more additions to the writing, presumably for further clarity. Can you always tell if something was written using AI? The most important part about catching cheaters who use AI to do their work is having a reasonable amount of evidence to show the student and the administration at your school if it comes to that. Maintaining a skeptical mind when grading is vital, and your ability to demonstrate ease of use and understanding with these tools will make your case that much stronger. Good luck out there in the new AI frontier, fellow teachers, and try not to be offended when a student turns in work written by a robot collaborator. It's up to us to make the prospect of learning more alluring than the temptation to cheat.
