Travel checklist that pulls weather + visa rules for your destination

Before every trip I go through the same painful ritual: check the weather, look up whether I need a visa, figure out if my adapter will work, look up the local customs around tipping. I want one tool that takes my destination, travel dates, and home country, and spits out a custom checklist — what to pack given the forecast, what documents to bring, what to know before I land. It doesn't need to book anything, just give me the prep list so I stop forgetting things.
