YC F26 startup Dydema launches non-invasive programmable brain-computer interface you can bind to keys, games and agents

Dydema (YC F26) has launched personal, programmable, non-invasive brain-computer interfaces: users pick a thought and bind it to anything — a key, a game, or an agent — with no surgery required.

A demo shared via Y Combinator's account shows a striking interaction pattern: a computer-use model suggests the most likely next actions, and the user accepts or rejects them with their thoughts — enough to fully control a computer, including playing games and answering email.
