Flyling

A tiny fruit fly whose learning runs on wiring mapped from a real fly's brain. Teach it a scent, test what it learned, and watch the cells that changed.

Flyling is a tiny fruit fly you raise and teach. Its learning runs on a model built from the MaleCNS connectome, a cell-by-cell map of a real male fruit fly's brain. Every Flyling hatches with the same wiring, and the lessons you give make yours different from everyone else's.

TEACH IT Pair banana with sugar and it learns to go closer. Pair vinegar with a puff of air and it learns to stay away.

TEST WHAT IT LEARNED Run a scent test and see which side it picks. Memories fade if you skip reviews, and sleep makes them stick, so a few minutes a day keeps your fly sharp.

WATCH ITS BRAIN After each lesson, open the brain view to see which memory cells lit up and which way the choice tipped. Replay the moment in slow motion.

CARE FOR IT Feed it sugar, let it rest, and keep an eye on hunger, mood and sleep.

PUT IT ON YOUR DESK In AR, point your camera at a table and Flyling lands there. In Canvas mode its walk draws a line you can save as a picture.

RECORD AND SHARE Record a clip with its brain on screen and share it to TikTok or anywhere else.

DECORATE Pick backgrounds, accessories, clip frames and sticker packs.

WHAT'S REAL The learning happens in a model of real fly wiring. Its body, quick reflexes and the scents it likes from birth were made by people. The Learn more page in the app lists every part.
