See Cali in action

A clean, professional desktop interface built for accredited metrology labs.

The most advanced Cali yet

Version 3 adds asset validation, a built-in AI assistant, email, SAP & API integration and environmental monitoring — on top of the true accuracy and audit-ready compliance Cali is known for.

🧭
Streamlined grouped navigation
A new top menu groups every module into Lab Work, Documents, Analysis, Quality, Business and System - with a contextual, collapsible sidebar, so any screen is a tap away on desktop and tablet.
🎯
Asset validation & intermediate checks
Intermediate checks and Shewhart control charts prove instruments stay in tolerance between calibrations and flag drift automatically.
🤖
Built-in AI assistant
Ask about instruments, due dates and non-conformances in plain language — the assistant reads your lab data through a secure proxy.
✉️
Email & smart reminders
Send certificates, reports and overdue reminders from Cali using your own SMTP, Gmail or Microsoft 365 account.
🔗
SAP & REST API integration
Two-way SAP PM/QM integration and an open REST API connect Cali to your ERP and in-house systems.
🌦️
Environmental monitoring
Record lab temperature, humidity and pressure with history and trends, and pull the latest conditions into every calibration.
Compliance auditor
A built-in auditor self-checks your data against ISO/IEC 17025, backed by 21 CFR Part 11 e-signatures and a tamper-evident audit trail.
🌡️
True, condition-corrected results
Cali calculates thermal expansion, temperature and air-buoyancy effects so every certificate shows the real result — verdicts based on the corrected value across all disciplines.
📈
Predictive recalibration intervals
Drift analytics project when each instrument will drift out of tolerance and recommend a safe calibration interval — recalibrate on evidence, not guesswork.
🤝
Works with Claude (Cowork)
Connect Cali to Anthropic’s Claude and simply ask — “what’s overdue?”, “any open non-conformances?” Claude reads your lab data live and read-only; nothing ever leaves your computer.
