i recently found a new platform that creates an elaborate plan for your app idea, and then reasons and sticks to that plan and any iterations until complete. it allows you to prompt it in between there also. the it runs the code on the browser so you can test it right there. It will also deploy directly from the platform. Databutton.com i dont have any affiliation with them but this community seems like the right place to place it. Especially with claude 3.7 thinking this tool along with all others cursor and windsurf are much more effective

Has anyone messed with the Custom instructions feature on chatgpt 3.5 turbo? what have been your successes
