Lobster AI and similar tools really aren't useful for most people.

Many see it as fresh and advanced, but once installed, they realize they don't actually have a practical use case.
Ordinary people mainly just chat, look up information, or write a bit—those ready-made tools on their phones are already enough.
People who would use these kinds of tools frequently and long-term are actually a minority.
To put it simply, it's not that the tools aren't powerful;
it's that the needs of the majority simply haven't reached that level yet.
