Are there any tools that do a similarity comparison of a token to all other tokens that have been launched before across popular platforms? So many knockoff relaunch scams out there

If I'm hearing you right, you want a tool that runs a semantic search of similar tickers / token names across chains and tells you which one was first, has the best lore, etc?

Haven't seen that, but seems like it would be super useful

It's A Really Concern But Unfortunately I Think no

Maybe try GMGN.AI, a URL that tracks newly issued tokens as well as token information

yeah, I get you. 
but I truly have no clue or heard about one. The only thing that can work is just paying attention.
