AI that runs the line

Before a defect
leaves the line,
AI finds it first

LineAI adds process-tailored customization on top of our own deep-learning core — detecting equipment anomalies, weld defects and surface flaws in real time, and closing the loop into process control automation. Add an enterprise AI assistant for the office, and the factory-to-desk rollout averages just 4–8 weeks.

/01 Why LineAI

Do these quality problems sound familiar?

The three problems we hear most often on the factory floor — and LineAI has a clear answer to each.

The limits of visual inspection

Verdicts vary with inspector skill and fatigue, and micro-defects are simply beyond the human eye.

AI inspects 24/7 to a single standard, down to the pixel

Escaped defects and recall risk

One defect found after shipment hits customer trust and cost hard. Reacting after the fact is always expensive.

Real-time verdicts inside the process stop defects on the spot

"We don't have enough defect data"

"AI needs thousands of defect samples," they say — a dead end for new lines and low-defect processes.

Our anomaly detection trains on normal data only, so starting is easy

/04 Products · Case Studies

Five products, proven on the floor

From line-side anomaly detection to an office AI assistant — see how each product solves real problems, through representative cases and use cases.

LINE SIGNAL · Time-series Anomaly Detection Engineer inspecting equipment
CASE STUDY 01 Chemicals · Reaction Process

Five days before the stop, the process sent a signal

Time-series data from reactors, piping and rotating equipment — temperature, pressure, flow, vibration — is learned in real time, catching subtle deviations before they become incidents or quality drift. Especially effective in continuous processes like chemicals and refining, where one stop means major loss.

Challenge

Unexplained drift in a continuous process

Intermittent quality drift and equipment trips kept forcing full-batch write-offs, and root-causing took four hours on average. Scheduled inspections showed no warning signs.

Approach

Anomaly scores from normal-pattern learning

  • 24 channels (temp, pressure, flow, vibration) collected read-only from the existing DCS/PLC
  • Model trained in two weeks on normal operation data only
  • Instant alerts to owners when anomaly scores cross thresholds
Result

Fewer stops, faster response

Early warnings averaging 5.2 days ahead enabled planned maintenance; unplanned stops fell 37%. Downtime savings alone paid back the investment in seven months. Now extended beyond detection into golden-batch correction proposals (LV.1).

LINE WELD · Weld Vision Inspection Welding with flying sparks
CASE STUDY 02 Battery Pack · Welding Line

Six months, zero escaped defects

Laser-weld imagery from battery module/pack assembly is fused with process signals to classify porosity, undercut, spatter and cracks in real time. Location and severity are quantified into cell-level quality history.

Challenge

Visual inspection fatigue — and escapes

Skilled inspectors checked every weld by eye, yet micro-porosity and undercut surfaced downstream 2–3 times a month. In batteries, one weld defect maps directly to fire and recall risk.

Approach

Image + signal fusion verdicts

  • Bead imagery and current signals analyzed together
  • Defect location, type and grade auto-logged to weld history
  • Cameras added only — no robot or fixture rework
Result

One inspection standard for everyone

Zero escapes in the six months since launch. Inspectors moved to verdict auditing and process improvement, and weld history now serves as customer-audit evidence.

* Figures reflect representative deployments and may vary by process and data conditions.

Challenge

No defect data to train on

A brand-new line with only 30 defect samples — and "we need thousands" answers from AI vendors nearly killed the project.

Approach

Learn normal, flag everything else

  • Anomaly model trained on normal product images only
  • The 30 defect samples used for validation only
  • Model continuously improved with defects found in operation
Result

Overkill and escapes, both under control

Deployed in four weeks at 99.2% accuracy and 1.8% overkill. Never-collected novel defects were still flagged as "different from normal," preventing first escapes.

* Figures reflect representative deployments and may vary by process and data conditions.
LINE VISION · Video QC/QA Monitoring Engineer monitoring the production floor
CASE STUDY 04 Materials · Process Safety

Time to awareness: 43 minutes to 8 seconds

Process cameras and CCTV are analyzed in real time to detect work anomalies, safety risks and process deviations — with instant alerts. Built on our video-analytics QC/QA core, it unifies quality and safety monitoring in one system.

Challenge

Dozens of CCTVs, only checked after the fact

People watched dozens of monitors, yet most incidents were confirmed in recordings after the fact — average awareness took 43 minutes.

Approach

Real-time stream analysis + instant alerts

  • Existing CCTV streams connected as-is
  • Abnormal behavior and process deviations detected in real time
  • Mobile alerts to owners with event clips attached
Result

Monitoring shifts from watching to responding

Average time to awareness dropped to 8 seconds, with zero safety incidents since launch. Control staff now focus on response, not repetitive watching.

Challenge

Information scattered everywhere

Policies on the intranet, accounts in spreadsheets, leave in groupware, minutes in shared folders. Finding one fact meant digging through three systems or asking whoever might know.

Approach

Modern RAG + permission-isolation architecture

  • Hybrid search + GraphRAG handles compound questions in one pass
  • Role/department RBAC — answers only from data the user may see
  • Encrypted at rest and in transit, with an on-premise LLM for confidentiality
Result

From asking around to just asking

Repetitive lookups on policies, accounts and schedules disappeared, and the assistant now handles most onboarding questions. Source links on every answer also cut misinformation.

Process-specific modelsEdge-optimizedMES/PLC/DCSClosed-loop control
OUTPUT · Deployment

Real-time verdicts & quality dashboard

Real-time verdicts start on the line within 4–8 weeks, accumulating into quality data.

That's why rollout is fast — and results are certain

Training generic AI from scratch for every project burns time and data. LineAI focuses on customization on top of a field-hardened core engine — lowering development risk while raising field fit.

  • Shorter time to deploy

    No core to rebuild — PoC to production averages just 4–8 weeks.

  • Lower failure risk

    Starting on a field-proven core removes the "we tried, it didn't work" scenario.

  • A model that fits your process

    No off-the-shelf models — defect characteristics, line speed and lighting are all tuned to your floor.

  • Natural systems integration

    Linked to MES, PLC and SCADA, inspection data flows straight into your quality systems.

/06 Agentic AI

From AI that answers,
to AI that works.

The LLM agent inside LINE ASSIST doesn't stop at finding documents. It calls your MES, ERP, and equipment systems as tools — querying, analyzing, and drafting actions that wait for your approval. People make the judgment calls; the agent does the repetitive work.

LINE ASSIST — AGENT SESSION
Why did the defect rate on Line 3 spike yesterday?
MES query · Line 3 hourly output & defect codes done
Quality history match · similar patterns, last 30 days done
Equipment log analysis · pressure deviation after 14:00 done
Defect rate rose from 1.2% to 3.4% after 14:00 yesterday. The top root-cause candidate is a nozzle pressure deviation on Unit 2 in the same window (3 similar cases · source: quality record QH-0412). A maintenance work-order draft is ready.
APPROVALIssue inspection work order — Unit 2 nozzleApproveHold
Multi-step autonomy

From question to system query, analysis, and drafted action — the agent plans and executes on its own. Hand over shift briefings and daily quality reports entirely.

Human-in-the-loop

Queries and analysis run autonomously, but any action that changes the real world requires explicit approval. Every step is written to an audit log.

Standard tool integration (MCP)

MES, ERP, and quality systems connect through a standard tool interface. Adding a system means adding a connector — the architecture stays the same.

* LINE ASSIST does not replace your MES — it is an agent layer that drives your MES and ERP as tools. Your existing system investment stays intact. Fully on-premise · zero external data transfer.

Defects people miss,
AI reports with coordinates and grades

Beyond pass/fail signals: defect type, location, size and confidence are recorded as structured data. Inspection becomes quality data, and MES integration puts the whole line's quality flow in one view.

  • Start with normal data only

    No mass defect collection — anomalies are detected from normal-image learning alone.

  • Location & grade auto-logging

    Each defect is localized and severity-graded, accumulating into quality history.

  • Real-time at line speed

    Edge-optimized lightweight models keep pace with your conveyor.

/03 Process Automation

Detection is not the end.
Verdicts become control.

The core technology that finds anomalies is the starting point of automation. LineAI implements closed-loop automation — detection wired into equipment control — step by step, from chemical batch processes to assembly lines.

FEEDBACK — control outcomes flow back as training data, sharpening the model continuously
BATCH · TIME-SERIES

Golden Batch operation

Temperature, pressure and feed profiles from your best batches become the reference trajectory. When a running batch drifts, corrections are computed and written to the DCS — batch-to-batch quality converges to the golden batch.

→ Less batch variance · stabilized yield
BATCH · PREDICTION

Batch end-point prediction

Reaction progress data predicts completion in real time. No habitual buffer time, no over-reaction — batches end exactly when they should.

→ Shorter batch cycle time
SOFT SENSOR

Virtual quality sensors (soft sensors)

Quality values once known only from lab analysis — concentration, viscosity, composition — are inferred in real time from process sensors. Quality deviations feed control immediately, no waiting for the lab.

→ No lab wait · real-time quality correction
VISION → ACT

Vision verdicts → equipment control

Inspection results drive rejectors and sorting robots to eject defects automatically. Recurring defect patterns feed back into upstream parameter adjustments — reducing the cause itself.

→ Auto-ejection · upstream improvement
PdM · CMMS

Predictive maintenance → automated workflow

Detected warning signs auto-generate CMMS work orders — with related parts, maintenance history and recommended scheduling attached. Maintenance becomes planned work.

→ Shorter maintenance lead time · fewer sudden stops
LLM AGENT · RAG

LLM operations agent

When anomalies occur, relevant SOPs and similar past cases are retrieved with step-by-step response procedures. Shift-handover reports are drafted automatically from process data.

→ Standardized response · automated handover

Advise

AI proposes corrections and actions; operators execute. The early stage where trust in AI judgment is verified.

LV.2 · HUMAN-IN-THE-LOOP
Approve

One-click operator approval applies the control. AI judges; humans make the accountable execution decision.

LV.3 · CLOSED-LOOP
Autonomous

Corrections apply automatically within the validated operating envelope. Outside it, interlocks trigger instantly and operators are called.

* We start within the PoC-validated envelope and raise autonomy step by step as data and trust accumulate.
