Personality Name Translator
One type, up to four names depending on region and version. Type any of them in and get the full identity: the chart position, every regional label, and the sliders that produce it.
Name confusion is the most common reason two Tomodachi Life players argue past each other. A US player on Switch calls a type Sweetie, a European calls it Softie, and a US player still on the 3DS original also calls it Softie, so "is Softie good with Charmer?" can mean two different questions depending on who is asking. The translator collapses all of that. Type any name from any version and it resolves to the underlying type, shows what that type is called everywhere else, and hands you a slider recipe in case you want to make one.
Which names changed between versions
More than half of the US roster was renamed for the Switch release. Softie became Sweetie, Optimist became Cheerleader, Lone Wolf became Observer, Trendsetter became Charmer, Entertainer became Go-Getter, Leader became Dynamo, Designer became Achiever, Adventurer became Visionary, Brainiac became Rogue, and Go-Getter became Maverick, which is the single most confusing swap of the lot since Go-Getter is now two different types depending on which version you are playing. Europe renamed far fewer types, and some of its names went the opposite direction. The full side-by-side lives in the US vs EU names guide, and the version comparison covers what else changed.
Why matching by name goes wrong
Suppose you are following an old 3DS walkthrough that recommends pairing an Artist with a Free Spirit. On the Switch both of those names are gone, and the same two Miis are now called Perfectionist and Strategist. Nothing about their behavior changed. The chart position is identical, the slider math is identical, and only the labels moved. That is why the dependable way to compare notes across versions is by position on the chart rather than by name, and why this tool always resolves names back to the type itself. If you want to spot a type without opening any menu at all, the identification guide teaches the behavioral tells.
Quick answers
Why does the same personality have four different names?
Nintendo of America and Nintendo of Europe localize separately and do not have to agree, and the Switch release renamed more than half of the US 3DS roster while Europe kept most of its old labels. One type can therefore appear under different names in a US 3DS guide, a European 3DS guide, a US Switch game, and a European Switch game.
Does the translated name change how the Mii behaves?
No. The personality under the label is identical everywhere. A Softie and a Sweetie are the same type with the same traits, the same spot on the chart, and the same slider recipe. Only the label differs.
I only know a name from an old video. Will this still find it?
Probably. The translator searches all four name sets at once, including the old 3DS names like Trendsetter, Entertainer, and Brainiac that no longer appear in the Switch game. If nothing matches, the spelling is off, or it is not one of the 16 personality names.
