Every Worker. Any Language. Every Site.
Plynthio is a mobile-first platform that verifies worker presence with geofencing, enforces structured safety workflows, and generates immutable audit records—so field operations teams always have proof of what happened on the ground.

AI Safety Audit Dashboard
The web dashboard displays AI-analyzed safety audit results, flagging incomplete JSAs and missing signatures across all active job sites in real time.
Mobile JSA Workflow
A field worker completes a structured Job Safety Analysis on their phone, stepping through hazard identification, control measures, and crew acknowledgments before work begins.
Signature Capture & Task Completion
Workers sign off on completed tasks directly on the mobile device. Each signature is timestamped, geotagged, and attached to the specific work record it verifies.
Multilingual Workforce Integration
Safety workflows render in the worker's preferred language, ensuring every crew member can complete JSAs, audits, and sign-offs accurately — regardless of their primary language.
Process
How It Works
Three steps from field activity to audit-ready documentation.
Worker Checks In On-Site
A crew member opens the Plynthio mobile app at the job site. The app confirms their identity, records their GPS location against the site geofence, and logs a timestamped check-in.
System Verifies & Enforces Workflows
Plynthio validates the worker's presence within the geofence boundary, checks their permissions for the assigned task, and requires completion of the correct safety workflow (JSA, inspection, or audit) before work can proceed.
Audit-Ready Records Generated
Every check-in, workflow completion, photo, and signature is compiled into an immutable record—timestamped, geotagged, and tied to the verified worker. These records are available instantly on the web dashboard for review, export, or audit response.
Capabilities
Core Features
Verified Presence
Geofencing + Timestamps
What it does: Each job site has a defined geofence boundary. When a worker checks in, Plynthio confirms their GPS position falls within that boundary and logs the exact time of arrival and departure.
Why it matters: Eliminates disputes about who was on-site and when. Provides defensible proof of attendance for billing, compliance reporting, and labor verification without relying on manual sign-in sheets.
Audit-Ready Workflows
Structured Logs + Immutable Records
What it does: Safety workflows like JSAs, site inspections, and equipment audits follow structured, step-by-step templates on the mobile app. Each completed step is logged as an immutable record that cannot be altered after submission.
Why it matters: When a regulator or client asks for proof that a safety procedure was followed, you can produce a complete, tamper-proof record showing every step, who completed it, where, and when—without assembling paperwork after the fact.
Access Control
Identity + Permissions
What it does: Every user has a verified identity tied to their role and certifications. Plynthio controls which sites a worker can access, which workflows they can complete, and what data they can view, based on their assigned permissions.
Why it matters: Prevents unauthorized personnel from entering restricted sites or performing tasks they're not certified for. Reduces liability by ensuring only qualified, approved workers handle safety-critical operations.
Built for the Field
Designed for Real Job Site Conditions
Field operations don't happen in an office with reliable Wi-Fi. Plynthio is built for how work actually gets done.
Works Offline
Workers complete check-ins, safety workflows, and task sign-offs even without cell service. All data is stored locally on the device and syncs automatically when connectivity returns. No work is lost.
Multilingual Workforce Support
Workflows, instructions, and interface elements display in each crew member's preferred language. This ensures every worker understands safety procedures and task requirements regardless of their primary language.
Compliance-First Architecture
Every record in Plynthio is immutable and tamper-evident. The platform is built from the ground up to satisfy audit requirements from OSHA, client compliance programs, and insurance carriers.
