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: 11 months ago

I also recommend subscribing to newsletters like new venture weekly (free) or Exploding Topics (freemium) for business ideas. Source: 11 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

Oh wow I did something very similar, just dumber. https://shopbysub.com I have a raspberry pi gathering Reddit comments with an Amazon link in them every hour, then exposing them on Shop By Sub categorized by subreddit, sorted by upvotes. Same with OP I put my Amazon referral link in there. It's been decently well-received by Reddit, but I have a hard time getting recurring users. It seems like they just forget... - Source: Hacker News / almost 2 years ago

In fact, I liked Reddit so much as a recommendation engine, that I built https://shopbysub.com so folks can browse Amazon product recommendations by subreddit with context and sorting and stuff. e.g. I've been gardening lately and came across a moisture meter on https://shopbysub.com/r/gardening that I wouldn't have otherwise. It's been instrumental to help my overwatering problem. Source: about 2 years ago

I created a site (https://shopbysub.com) that kind of does this. You can browse amazon products that have been linked by redditors in comments by subreddit - e.g. https://www.shopbysub.com/flashlight. Source: almost 3 years ago

I did a thing to somewhat help mitigate this problem. I made https://shopbysub.com which groups Amazon products left in reddit comments by subreddit, and makes them sortable by amount of upvotes. So you can go to e.g. https://shopbysub.com/r/BuyItForLife and see all the amazon products more or less recommended by redditors. Source: over 3 years ago
