Catch strain before it becomes injury
Score any task from a short video against RULA, REBA, and NIOSH, get the fix, and prove it worked with a re-assessment — so every risky task gets checked, not just the few a consultant had time for.
Put the right agents to work
Ella coordinates ergonomics, safety, and wellbeing — and you approve every action.
From video to risk score
Drop in a clip of the work. Pose estimation scans every frame, tracks each joint, and scores the posture — then hand it to Ella for a fix.
Tracking poseUpload a video
Capture any task on the floor and drop it in — MP4, MOV, or AVI.
AI detects posture
Pose estimation tracks every joint and angle, frame by frame.

REBA
Moderate load on spine, shoulders and joints.
RULA
Moderate upper-limb strain. Investigate posture.
NIOSH
Lifting load within safe limits.
Snook
63% of workers can perform this task safely.
WISHA
Hazardous posture; implement changes.

Track risk across every frame
Not a single snapshot — the whole clip is scored so you see exactly when a task crosses the action limit.
Fixes your team can actually apply
Every flagged joint turns into a specific, task-level intervention — not a generic warning.
Elbow
Right elbow bent past 100° while bearing load.
Neck
Neck flexed 28° forward for most of the cycle.
Wrist
Wrist deviates during grip on the far reach.
See ergonomic risk before it costs you
Roll risk scores up across tasks, stations, and sites to see where strain is building — and prove the impact of every fix. Fewer sprains and strains, fewer recordable injuries, and a program you can stand behind in an audit.
- Assess every task, not just a sampled few

We've put together the most common questions to help you get started quickly.
How does Knowella assess ergonomic risk?
Upload a short video of a task and Knowella uses pose estimation to track posture and joint angles, then scores the task against recognized methods like RULA, REBA, and the NIOSH lifting equation — no wearables or on-site consultant required.
Which assessment methods are supported?
RULA (upper-limb strain), REBA (whole-body posture), the NIOSH lifting equation, and manual-handling assessments for push, pull, and carry tasks — the same frameworks ergonomists use.
Do we need special hardware or wearables?
No. A standard video clip from a phone or camera is enough. The analysis runs on the footage, so you can assess a task anywhere on the floor in minutes.
What do we get back from an assessment?
Validated risk scores with a plain-language verdict, annotated pose snapshots, task-level recommendations, and a corrective action you can approve — plus a scheduled re-assessment to confirm the fix worked.
Is a human still in control?
Always. Knowella scores the risk and proposes the fix, but the corrective action only opens once your team approves it. Every assessment and action is logged.
Can we track improvement over time?
Yes. Re-score the same task after a change and compare before vs. after, and roll risk scores up across tasks, stations, and sites to see trends.
How does this connect to our safety program?
Ergonomics works alongside incident, wellbeing, and compliance workflows, so early symptoms and risky tasks feed the same view your EHS team already uses.
