## Nauti's Take

Upside: undsh.com nicely shows how fast Cursor now turns small ideas into working tools — one idea, fifteen minutes, done. Handy for anyone wanting to spot or clean AI text before shipping. The catch: the em-dash was never a reliable AI detector and matters less with every model update — durable AI detection needs other signals. Cute for PRs and emails, but not a real game-changer.
