Site safety · EHS triage
The hazard you walk past is the one that hurts someone. Snap any job site and SiteSentinel reads it back in seconds — PPE compliance, hazards ranked by severity, housekeeping, and a corrective-action list your supervisor can act on or attach to the daily log. Built on Astra AI.
PPE & fall protection · Struck-by & electrical · Housekeeping · Seconds, not site walks
One unguarded edge. One missing hard hat. One look that nobody took.
Construction is one of the most dangerous industries there is — and most incidents trace back to a hazard that was visible before anyone got hurt. The problem was never seeing it once. It was seeing it every time, on every crew, before the shift starts.
Trailing leads, an unguarded leading edge, a hard hat that came off in the heat. By the time it's in an incident report, everyone agrees it was obvious. The cost of a missed look is measured in injuries, downtime, and claims.
One competent person, a dozen work fronts, a clipboard, and a shift that's already moving. Spot checks slip. The pre-task walk gets shortened. The gaps are not negligence — they're physics.
By the time observations are written up, the crew has moved on and the condition has changed. The record that matters most for safety and for the file is the one captured in the moment — not at the end of the day.
SiteSentinel doesn't replace the look. It makes sure one happens — on every photo, in seconds, with a written record your competent person can review and own.
Try it now
Upload a job-site photo (or load our sample) and SiteSentinel returns a structured draft observation in seconds — PPE, hazards by severity, housekeeping, what's being done well, and corrective actions. Photos are analyzed in the moment and not stored.
SiteSentinel is a safety triage aid, not a certified inspection and not a compliance determination. A qualified competent person reviews every site. Photos are analyzed in the moment and not stored.
How it works
Use the phone already in your pocket. Capture the crew, the scaffold, the edge, the panel — whatever you'd glance at on a walk. No app to install, no kit to deploy.
It checks PPE person by person, surfaces hazards and ranks them by severity, notes housekeeping, and flags what's being done well — reporting only what's actually visible in the frame, marking the rest unclear.
Clear corrective actions and a one-line risk read, ready for your competent person to review, action, and attach to the daily log. The look happened, in seconds, and it's written down.
What it reads
SiteSentinel returns a structured observation — not a vague verdict. Every section is grounded in what's visible in the photo, so your competent person knows exactly what to verify on the ground.
Hard hats, hi-vis, eye and fall protection, gloves, footwear — flagged compliant, missing, or unclear, person by person, with a short note on what it saw.
Trip-and-fall, struck-by, unguarded edges, electrical, working at height — surfaced and ordered so the high-severity items come first, with a location cue for each.
Trailing leads, blocked egress, material storage, debris and clutter — the everyday conditions that quietly turn into incidents, called out plainly.
Good practice gets named, not just gaps. Positive observations give crews credit and make the record fair — and more useful in a toolbox talk.
Each finding pairs with a clear, do-this-next instruction your supervisor can assign on the spot — not jargon, just the fix.
A one- to three-sentence read of the overall risk and the priorities — plus copyable JSON to drop into your own log, app, or report.
A real read
A representative SiteSentinel observation from the sample photo below. Run it yourself in the tool above — every read is generated live from your image.
Active site with good baseline PPE; priority is separating ground crew from the excavator's swing radius and confirming fall protection on open scaffold. Verify on the ground.
Illustrative output. Findings are generated live from the photo you submit and are a draft for review by a competent person.
Who it's for
Run a pre-task safety read on every work front from your phone before the shift moves — without leaving the trailer or shortchanging the walk. Catch the gap while it's still a photo, not an incident.
Triage dozens of fronts a day and put your time where the risk is highest. Generate consistent, written observations you can review, action, and file — the same checklist, every photo, every crew.
Give every super and sub the same fast safety read across a portfolio of jobs. Standardize what a spot check looks like and build a photo-backed record that travels with the project.
Before you start the task, snap the area and get a plain-language fix list — no clipboard, no jargon. Use it to brief the crew in a 60-second toolbox talk that actually names what's in front of them.
Why Astra AI
SiteSentinel is built by Astra AI on MIND, our knowledge-graph platform. It reads only what's visible in the frame, marks anything uncertain as unclear rather than guessing, and hands the judgment back to a qualified person. The look is faster and more consistent; the responsibility stays human.
It reports what it can see and flags what it can't — no invented people, equipment, or violations. Uncertainty is labeled, not hidden.
Photos are analyzed in the moment to produce the read and are not stored by SiteSentinel. The observation is yours to keep, file, or discard.
The same Astra AI platform behind a growing family of products — engineered so the software earns trust by being accurate and honest about its limits.
Astra AI's core platform is the subject of pending patents. SiteSentinel is one of the products built on top of it.
Questions
No — and it's designed not to. SiteSentinel produces a draft observation to support a qualified competent person. It is not a certified inspection and not a compliance or OSHA determination. The human still inspects, decides, and signs off; SiteSentinel just makes sure a fast, consistent look happens and gets written down.
It's a triage aid, not a verdict. It reports only what's visible in the photo and marks anything it can't resolve — distance, angle, image quality — as unclear rather than guessing. Treat it like a sharp second set of eyes that never gets tired, then verify on the ground.
PPE compliance person by person (hard hats, hi-vis, eye and fall protection, gloves, footwear), hazards ranked by severity (trip-and-fall, struck-by, unguarded edges, electrical, working at height), housekeeping, positive observations, and a corrective-action list with a supervisor summary.
No. Photos are analyzed in the moment to produce the read and are not stored by SiteSentinel. The resulting observation is returned to you to keep, file, or discard as you choose.
No. SiteSentinel runs in the browser on the device you already carry. Open it, drop in a photo, get the read. Nothing to deploy on site, no kit, no account required to try it.
Yes. Every read includes a copy-to-clipboard JSON export so you can drop the structured observation straight into your daily log, safety app, or report.
Take the look — in seconds, on every photo. SiteSentinel hands the read to your competent person, and the record writes itself.
