Everything Your Maintenance Team Needs — Nothing They Don't

Report what you observe — vibration, temperature, noise, visual indicators — and the engine calculates posterior probabilities across all known failure modes in real time. Each observation you add narrows the diagnosis further, recommending the next inspection that provides maximum information gain. No black-box guessing; every probability is explainable and auditable.

Every asset in your fleet gets its own Bayesian model with failure-mode weights calibrated to that specific piece of equipment. Models incorporate time-decay functions so recent diagnostic history weighs more heavily than older events. Models are transparent CSV files you can inspect, edit, and version-control — no locked algorithms.

When a technician at one site resolves a fault, the outcome feeds back into shared fleet models. Diagnostic accuracy improves across every identical asset in your organization. The more your team uses FaultGuard, the smarter it becomes — creating a compounding advantage that no competing tool can replicate.

Ask plain-language questions about any piece of equipment and get answers grounded in your own manuals, service bulletins, and SOPs. Every response includes source citations so you can verify and trust the output. The Retrieval-Augmented Generation pipeline runs on-device, meaning it works even at sites with zero connectivity.

Every completed diagnostic session captures the technician's observations, reasoning path, and resolution outcome. This creates a living knowledge base that survives retirements, transfers, and turnover. Junior technicians inherit the pattern-recognition instincts of your most experienced operators without years of on-the-job learning.

FaultGuard automatically generates troubleshooting guides for each asset based on accumulated diagnostic data, manual content, and fleet-wide outcomes. Guides stay current as new failure modes are discovered and resolved. Read our troubleshooting guides on the blog for examples of what these look like in practice.

FaultGuard's industry-first danger tag system assigns a severity rating to every repair procedure based on voltage levels, pressure hazards, confined-space requirements, and chemical exposure risks. Tags are color-coded — green, amber, red — so technicians immediately understand the risk profile before beginning any work. Tags include required PPE, minimum skill certification, and mandatory lockout/tagout steps.

Before presenting repair steps, FaultGuard runs an automated risk assessment that evaluates the hazard category, required competency level, and environmental conditions. If a procedure exceeds the logged-in technician's certification level, the system flags it and recommends escalation. This built-in safety gate reduces incident risk and ensures compliance with your organization's safety policies.

Every completed diagnostic session produces a standardized PDF report containing the asset identifier, reported symptoms, Bayesian analysis results, inspection steps performed, final diagnosis, repair actions taken, and safety tags applied. Reports are emailed automatically to designated recipients and stored against the asset record. No more handwritten notes transcribed hours later at a desk.

Every action in FaultGuard is timestamped and attributed — who ran the diagnosis, what they observed, which repair path they followed, and when the asset returned to service. This immutable audit trail satisfies regulatory inspection requirements and provides a defensible compliance record. Filter by asset, technician, date range, or fault category to surface exactly the history you need.

Every asset gets a complete maintenance timeline: diagnostic sessions, PM completions, part replacements, document attachments, and technician notes. Scan a QR code or tap an NFC tag on the equipment to instantly pull up the full history on your mobile device. Link manuals, drawings, photos, and service bulletins directly to each asset record.

Calendar-based preventive maintenance scheduling with configurable intervals, checklists, and assignment rules. Build rounds workflows that route technicians through a sequence of inspections at optimized intervals. Track compliance rates, overdue items, and completion metrics from a single dashboard. Schedules sync across devices so field and office stay aligned.

Pre-cached map tiles show asset locations, PM status indicators, and proximity-based alerts on an interactive map that works without an internet connection. Technicians can navigate to equipment in the field, see which assets are due for service, and filter by status or type. Map data syncs automatically when connectivity is restored.

FaultGuard's core engine — Bayesian diagnostics, RAG chat, danger tags, asset history, and reporting — runs entirely on-device. There is no dependency on cloud connectivity for critical operations. AI inference happens locally using optimized on-device models. Your technicians get the full diagnostic experience whether they are in a server room or a remote desert wellhead with zero signal.

Completed diagnostic sessions, PM records, and knowledge-base contributions queue locally and sync automatically when the device reconnects. Conflict resolution is handled gracefully — no data loss, no duplicate entries. Fleet learning models update in the background so every device benefits from the latest diagnostic outcomes across the organization.
