Frequently Asked Questions
Is this an official Nintendo Mii creator?
No. This is a fan-made, browser-only tool that approximates how Mii appearance and personality work in Tomodachi Life. It is not affiliated with or endorsed by Nintendo.
How accurate is the personality prediction?
It is a community-estimate model. The in-game algorithm is not public, so the 4 sliders map to one of 16 personality types by a heuristic. Treat results as a guide, not a guaranteed in-game outcome.
What does the name generator do?
It suggests 8 cute Mii-style names based on the predicted personality group. Click one to fill the name field, or type your own.
Can I share my Mii with friends?
Yes. Use 'Copy JSON' to put the full appearance + sliders + personality on the clipboard, or 'Download JSON' to save a file. No data is uploaded to any server.
