That's exactly the problem though.
ChatGPT can recommend tools, but it doesn't tell you whether people actually use them, like them, or think they're worth paying for.
If I ask for a video AI tool, I'll get a list. If I go to a community-driven directory, I can see reviews, upvotes, alternatives, pricing, new launches, and what real users prefer.
People still use Product Hunt even though ChatGPT exists. Discovery and community validation are different things.
