Cursor 3 minute demo - the most popular AI code editor

0:00 here's the cursor demo that I show to developers who haven't tried it before I just try to cover three things the integrated chat command K tocode with natural language and debugging with AI cursor is a vs code fork and you'll just see this additional plane here on the right hand side I'm going to ask this write a implementation of The Game of Life in Python animate the output in the console you can see here we have different models that we can choose from Claude 35 son it's the best for writing code uh as of today uh but you can also use 01 you can use gbt 40 um and you see here that it's going to not only write the code but it gives some explanation

0:45 you can either click this button and copy or you can click this apply and they've got a a kind of a whole model dedicated to making diffs to your existing code I'm going to accept them I will open this in the integration terminal and we'll run it and we have a fully functioning Game of Life on the first try this is code that I could probably write uh on my own it would take me a few hours it would not be nearly as succinct uh and it definitely would not run on the first try uh so just this functionality alone just simply bringing the chat into the IDE in my opinion is worth the 20 bucks a month second thing that cursor did you can

1:31 select uh a chunk of code I'm here just going to select all of it and I'm going to press command K and I'm going to ask it to make some changes to my code double the size of the board uh make it green like an apple 2E submit that edit and now you can see a little bit more of that diff in action so it found where the board was defined and then down here it found the color and so I can click accept save that open up the terminal again rerun my program and now we have something that looks more like an apple

2:17 2E uh so this functionality is pretty incredible right you're making changes to your code in natural language and that's really powerful not just for developers but for uh folks who maybe have always wanted to learn to code but never have uh I would say that coding is probably never been more accessible than it is right now uh third thing that is really useful here is debugging Let's Pretend there was a syntax error that for some reason we would not have caught with the other plugins that we might have installed here I'm going to run this again I'm going to get my Trace back I can highlight the trace back and you'll see this button pops up that says add to chat and so I'll add that Trace back to chat I'll say fix this error

3:02 and it identifies the error it gives me a fix I click apply and it applies a fix I don't have to copy paste the code figure out where that fix goes it just kind of takes care of that for me I run the code again and it works again uh look I don't want to overhype this this is an AI demo and the demos are always better than reality we're starting from a blank file here not dealing with a big code base we did not encounter any hallucinations and you will uh but there are very real pred activ it gains here so if you have not tried cursor yet would encourage you just to go to their site download it try it out for a week or so and just see how it works for you
