Tabbit AI trend pick
Dapper GrandpaCodex desktop petA dapper, funny American grandpa
Tabbit has been tracking a fun little direction in the AI world: people want tools that feel stronger, but also workspaces that feel more companionable. So we turned the Codex pet idea into a ready-to-install Dapper Grandpa desktop pet.
Dapper Grandpa is a humorous, well-dressed American grandpa character: a plain dark navy suit and red tie, no flags, badges, pins, or text marks. The animations use a salute, tea cup, red-and-gold folding fan, and blank scroll to keep the mood polite and friendly.
