The concept
Sawmill is a paired bedside snore journal + AI snore-risk analyzer that helps adults figure out if their snoring is a benign annoyance or a warning sign of obstructive sleep apnea. The physical kit is a printable week of bedside cards your partner fills in (snore volume, breath pauses, time gasping); the digital tool scores the entry against validated screeners (STOP-BANG + Epworth) in 60 seconds and tells you whether you should book a sleep study. Free analyzer, $5/mo Pro tracks 90 days, generates a doctor-ready PDF, and predicts your apnea-hypopnea index trend.

Where it stands
The archived incubator verdict was BUILDIT. That is an internal research signal, not a current market claim.
