An in-depth tutorial on creating (coding) actions for custom GPTs. I took the simplest approach possible:
No servers/domains needed
No money needed
No development setup needed - all in browser
No convoluted deployment process - you click "Save" and your action is updated
Uses JavaScript/TypeScript so ChatGPT is pretty good at helping
