C-SATS vs Theator (2026)
Both turn surgical video into feedback, by different means. C-SATS, owned by Johnson and Johnson MedTech, takes video from any minimally invasive platform, uses AI to remove patient information and segment steps, and has crowd reviewers score technique on the published GEARS and GOALS instruments, with expert surgeons adding feedback. Basic membership is free. Theator records every case automatically from cameras already in the operating room, uses computer vision and vision language models to identify steps, safety milestones and critical events, and links the video to the patient record for quality review, standardization and training. Choose C-SATS for scored technique review of individual surgeons; choose Theator for automatic analysis across a whole surgical department.
- Surgeons want their technique scored on published instruments.
- Expert surgeons should add feedback beside the scores.
- You want to start free, with a Basic membership.
- Every case should be recorded and analyzed automatically, with no upload step.
- Video should link to the patient record for quality review.
- Department leaders want analytics on standardization and efficiency.

Product / capability
Theator's AI Assistant can now assess suturing on a recorded case: asked to assess the suturing, it samples up to three annotated suturing segments and returns seven needle handling checks based on the EASE framework, each with the visual cue it used and the clip to play.

C-SATS (Crowd Sourced Assessment of Technical Skills) is a surgical video assessment platform owned by Johnson and Johnson MedTech. Surgeons capture video from any minimally invasive surgery platform, by C-SATS hardware or upload, to a HITRUST CSF certified case library hosted on AWS in Oregon.

Theator turns the video from laparoscopic and robotic cameras already in the operating room into structured surgical data. A small video unit connects to the existing camera tower, removes identifying content at capture and sends the video to Theator's cloud, where a proprietary vision language model trained on more than 600,000 curated procedures across 9 specialties and 180+ procedure types identifies steps, instruments, anatomy, safety milestones, complications and complexity.

Questions buyers ask
How do C-SATS and Theator handle patient data?
For C-SATS, the hospital or surgeon is the data controller and a Johnson and Johnson affiliate the processor, under a business associate agreement.
The video unit strips patient and staff identifiers and metadata, removes frames recorded outside the body at 99.3 percent accuracy and applies k anonymity of at least 3, a method Theator developed with former Mayo Clinic chief information officer Cris Ross and published in JAMA Surgery in 2023. De identified video then travels over a VPN to a HITRUST certified cloud, and Theator says every new procedure deepens the model. From the AI Health Index, drawn from each vendor's own published materials and the regulatory record, verified September 29, 2026. No vendor pays for placement.
What evidence is published for C-SATS and Theator?
In C-SATS's case, the home page's headline figures come from what the company labels an unpublished exploratory analysis: about 3,000 cases across six specialties and 25 procedure groups, comparing surgeons in the top and bottom quartiles of GEARS scores, with confidence intervals and no adjustment for multiple testing.
For Theator, a Mayo Clinic study in the Journal of the American College of Surgeons (2025) compared AI operative reports with surgeon written ones in 158 robotic prostatectomies, using expert review of the video as ground truth, and found overall accuracy of 87.3 percent against 72.8 percent. From the AI Health Index, drawn from each vendor's own published materials and the regulatory record, verified September 29, 2026. No vendor pays for placement.
How much do C-SATS and Theator leave to the clinician?
Scores come from crowd reviewers and expert surgeons applying published instruments; feedback returns to the surgeon's own dashboard; video sharing stays within the institution and, in some instances, the C-SATS community; and the How it Works page says health systems can see trends and performance across the surgical team. Enterprise licenses cap expert reviews at two a month and quantitative scores at twelve a year per license.
In Theator's case, a Miami pilot reported a median of 6 edits per case. Quality, safety and benchmarking outputs go to dashboards for surgeons, department chairs and quality officers, who decide what to act on. From the AI Health Index, drawn from each vendor's own published materials and the regulatory record, verified September 29, 2026. No vendor pays for placement.
