Activ Surgical ActivSight vs Theator
Theator reads recorded surgical video to draft the operative report. ActivSight shows blood flow while the surgeon operates. A health system with a robotic or laparoscopic program that wants documentation, billing and quality data from video buys Theator, which says it is embedded in Epic and Oracle Health. A surgeon-led team after dye-free perfusion views buys ActivSight.
Theator's homepage puts documentation accuracy above 95%. The 2025 JACS study it cites, covering 158 robotic prostatectomies, found AI reports 87.3% accurate against 72.8% for surgeon-written ones, and Theator staff co-authored it. The University of Miami result of a 70% faster final note sits in a footnote on Theator's own site.
Theator has no 510(k) on record, while ActivSight has two. A hospital that gates pilots on a 510(k) number therefore starts with ActivSight. The 2,000 cases and 20% plan-change figure ActivSight cites are the vendor's own numbers.
