Show HN: Use GPT4 to quickly build simple, shareable web apps

10 pointsby abiabout 2 years ago
Hi everyone,<p>I built a quick experiment last weekend that allows you to use GPT4 to quickly generate single page web apps. These apps are immediately deployed at a shareable and bookmark-able web URL.<p>Even though I’m a programmer, I think the idea of letting users build little apps without coding to solve their own problems is super exciting. I specifically built this because I wanted to solve a tiny problem of mine. I have a goal of running 500 miles this year. I track my runs on Strava and it shows me the total number of miles for the year. But I wanted to know: how many miles should I have run by this point in the year to be on track? I prompted and iterated with Pico and a few mins, I had a simple app: [<a href="https:&#x2F;&#x2F;backend-pico.onrender.com&#x2F;gender-hybrid](https:&#x2F;&#x2F;backend-pico.onrender.com&#x2F;gender-hybrid)" rel="nofollow">https:&#x2F;&#x2F;backend-pico.onrender.com&#x2F;gender-hybrid](https:&#x2F;&#x2F;bac...</a> that I could add to my iPhone home screen.<p>The apps built by Pico have lots of limitations (single page, can only use HTML&#x2F;CSS&#x2F;vanilla JS + popular JS libraries) but they can also be incredibly powerful and surprisingly useful sometimes. And sometimes, Pico will completely fail to generate anything useful :(<p>Here are some fun things you can build:<p>* Wordle, Tic Tac Toe, any simple game.<p>* TODO list.<p>* Daily affirmations&#x2F;horoscope.<p>* Camera filter app<p>* Audio recorder and processor<p>* “App for lumberjacks”<p>See website for demo apps.<p>I would love to hear your feedback and see what you build with Pico.

Dude, this is way gnarly. I am a senior citizen (aged 29+++) who prefers large fonts, so I created 2 simple web apps, using your excellent program -<p>1) simple word processor with 30 pt font size and brown text color <a href="https:&#x2F;&#x2F;backend-pico.onrender.com&#x2F;bicycle-bah" rel="nofollow">https:&#x2F;&#x2F;backend-pico.onrender.com&#x2F;bicycle-bah</a> 2) bit larger font and blue in color <a href="https:&#x2F;&#x2F;backend-pico.onrender.com&#x2F;chrysler-randomisation" rel="nofollow">https:&#x2F;&#x2F;backend-pico.onrender.com&#x2F;chrysler-randomisation</a><p>Thank you much, good sir. I hope you keep the links up, because I intend to use them.<p>GPT4 and all these new AI stuff impress the heck out of this old dude every day.

This is really cool. I had a lot of fun building a hangman style game just now! It took 3 prompts to get it right... here was my third iteration (sorry, didn&#x27;t save the first two): There is a problem where player 1 is unable to enter the secret word at the very beginning. Fix this issue. Also, clear the letter from the input after each time player 2 makes a guess, but display the incorrect guesses somewhere and don&#x27;t allow player 2 to guess the same letter more than once.<p>I think it got a little confused with my last prompt: &quot;Make both players also able to submit the input with the enter key.&quot; It correctly added the functionality, but it left it&#x27;s explanation in the HTML of the page too. Still very cool. Here is the working game: <a href="https:&#x2F;&#x2F;backend-pico.onrender.com&#x2F;hyundai-interface" rel="nofollow">https:&#x2F;&#x2F;backend-pico.onrender.com&#x2F;hyundai-interface</a>
