Sounds pretty similar to the situation I found myself in. I discovered a few newsletters/tools: trending insights (free), exploding topics ($39/mo), and trends.co ($300/ yr). Source: 10 months ago

I also recommend subscribing to newsletters like new venture weekly (free) or Exploding Topics (freemium) for business ideas. Source: 10 months ago

Best to start with what you're good at doing, check websites like exploding topics and answer the public to see if there is hype/market around your skillset. Get started by helping people in that niche for free, use AI tools to supercharge your work and find clients. Rinse and repeat until you start making money. Source: 12 months ago

There are places that can even help you find the perfect niche to go into like exploding niches, exploding topics to name a few. Source: 12 months ago

The good news for you is starting newsletters is easier than ever. If you are not interested in starting something in your field newsletters like exploding niches or websites like exploding topics are great resources to get ideas. Source: 12 months ago

Https://stackoverflow.com/documentation : This product could have been the most useful data source for today's Codegen AIs. Alas, it didn't succeed. Source: about 1 year ago

That was compiled from the now shutdown Stack Overflow Documentation. Source: over 2 years ago

They're just reformatted reproductions of the Stack Overflow Documentation project which shut down August 8th, 2017. The information within is becoming more and more out of date. Goalkicker is a bit deceitful in the way they indicate the last update of thier material which doesn't apply to the content but only formatting. Goalkicker has never, to the best of my knowledge updated the content in any meaningful way. Source: over 2 years ago

They took a shot at the "encyclopedic and comprehensive" bit with Documentation which was ultimately a failure. Source: almost 3 years ago

No, it was real documentation. It is a discontinued project by Stack Overflow. See more at the link I provided. Source: about 3 years ago
