GUS.ai

Industrial AI co-pilot for dairy and food processing.

Agentic AI that understands your plant -- documents, sensors, batch records, and PLC programs -- and answers engineering questions with cited evidence from your own operational data.

Live on a production ACV01 Automated Cheese Vat

What is GUS.ai

Three knowledge sources.
One conversation.

GUS.ai is an agentic AI system purpose-built for industrial food and dairy processing plants. It combines three knowledge sources that plant engineers have never been able to query together: your document library, your live sensor data, and your PLC logic.

Ask GUS.ai why a set time exceeded spec. It will retrieve the SOP target from the recipe document, pull the actual step timing from the telemetry data, and tell you exactly how far off you ran -- with citations for both sources.

Faster troubleshooting for plant operations. A complete record for management. Evidence-backed and traceable answers for compliance.

gus.ai -- ACV01

Why did the set time run long on last night's batch?

Set time target per recipe spec: 3:00:00. Actual elapsed from telemetry: 5:10:22 -- +72% over spec. Vat temperature held at 88.4F (within range). pH trending data shows coagulation onset delayed by ~18 min relative to historical median. SOP Section 4.3 recommends verifying rennet dose rate if set time exceeds target by more than 30 min.

Capabilities

What GUS.ai can do

11 AI tools, 40+ API endpoints, 5 communication channels -- built to answer the questions plant engineers actually ask.

Document Intelligence

Semantic search across SOPs, P&IDs, equipment manuals, recipe specs, parts lists, and commissioning reports. Every answer cites the exact source, page, and section.

679 chunks across 8 ingest pipelines

Live Telemetry

Real-time sensor data from your process. Current values, time-series trends, and threshold monitoring across every instrumented point in your plant.

3,897 tags searchable in real time

Batch Analytics

Step timing analysis, batch history comparison, and spec-vs-actual deviation detection. Automatic batch boundary detection without MES -- discovered from raw tag transitions.

Duration, temp milestones, cross-batch trends

PLC Intelligence

Parsed L5X programs -- 88 UDTs, 2,027 controller tags, and 480 alarm definitions indexed as 334 RAG chunks. Ask about any rung, any tag, any alarm in natural language.

Full Allen-Bradley ControlLogix coverage

Process Intelligence

Anomaly detection using MAD-based z-scores with coincident spike grouping. Multi-tag Pearson correlation analysis. Impact propagation, root cause analysis, and single-point-of-failure detection across a 30-node dependency graph.

Anomaly detection + correlation + causal reasoning

Multi-Channel Access

Ask GUS.ai from the web app, by email, by text message, by phone call, or by Telegram. Get answers wherever you are -- on the plant floor, in the office, or on the road. Same AI pipeline on every channel.

Web + Email + SMS + Voice + Telegram

Proactive Alerts

Automatic email notifications on batch start/end and CIP transitions. Heartbeat monitor sends Telegram alerts for alarms, step changes, and abnormal conditions. System status monitor with incident/recovery emails.

Batch alerts + heartbeat + status monitor

Audit & Compliance

Append-only audit trail of every query, tool call, and response. Daily digest emails with per-user breakdowns. Golden question management for QC evaluation. Full CSV export. Clerk JWT authentication with invite-only access control.

Immutable logs + daily digest + CSV export

Equipment Expertise

Pump curves, heat exchanger specs, RTD calibration data, flowmeter configurations, automated valves, and level transmitters -- any component or instrument in your process.

Fristam, Enerquip, E+H specs indexed

Streaming & Reasoning

Answers stream in real time via Server-Sent Events -- no waiting for the full response. Extended thinking display shows the AI's reasoning process as it works through your question, tool by tool.

SSE streaming + visible chain-of-thought

Visualization

See your plant, your code, your data

Four interactive 3D graphs, a live digital twin dashboard, and a causal reasoning panel -- all built into the same interface.

Live Monitoring

Digital Twin Dashboard

Real-time ACV01 vat overlay with positioned sensor callouts, radar chart performance view, gauge cards, health score, active alerts, and mini sparklines. Make Room view shows all vats at once with 10-second refresh.

AI Architecture

Right model for the right job

GUS uses five specialized AI models from two providers -- each chosen for a specific task, balancing reasoning depth, speed, and cost.

Powered by Claude

Claude Opus 4.6

Deep Reasoning & Graph Intelligence

Powers interactive code graph, knowledge graph, and docs graph conversations -- deep structural analysis and architectural reasoning across the entire codebase.

Highest reasoning

Claude Sonnet 4.6

Core Agent Brain

The primary orchestration model. Manages an 11-tool agentic loop with extended thinking -- deciding which documents to search, which tags to query, and how to synthesize evidence into cited answers.

11-tool orchestration

Claude Haiku 4.5

Real-Time Descriptions

Generates instant purpose descriptions for graph nodes on click. Optimized for sub-second latency with server-side response caching.

Low latency

Automatic GPT-5.2 failover for 99.9% uptime

Powered by OpenAI

Whisper

Voice-to-Text

Transcribes spoken questions into text for the agent pipeline. Operators can ask GUS questions hands-free from the plant floor via voice, phone, or kiosk microphone.

Speech recognition

TTS-1

Text-to-Speech

Reads answers aloud with natural voice synthesis. Multi-provider support (OpenAI, ElevenLabs, Mistral). Enables hands-free operation during production runs and equipment inspections.

Designed

Built by APT

Process engineers who build AI

Advanced Process Technologies (APT) is a 100% employee-owned process engineering and equipment manufacturing company headquartered in Cokato, Minnesota. Since 2000, APT has designed, fabricated, programmed, installed, and commissioned processing systems for dairy and food plants across North America -- from three manufacturing facilities spanning Minnesota, Idaho, and California.

APT's flagship product is the Advanced Cheese Vat (ACV), a patented design with three U.S. patents that improved yields, reduced maintenance, and set a new standard for process control in cheesemaking. Led by an on-staff Master Cheesemaker, APT provides recipe development, process optimization, and 24/7 engineering support.

We are not a software company that learned dairy. We are process engineers who built an AI system because we understood exactly what information our operators needed and couldn't get fast enough.
