Free Tools & Assessments

A few useful tools we’ve built over the years. No signup required — use them, share them, and if you want help implementing the “real system” behind the tool, we can help.

These tools are built from real projects—production reporting, quality, maintenance, and operational visibility. They're designed to be quick, practical, and easy to share internally.

If a tool highlights a bigger opportunity (too much manual work, inconsistent data, no visibility), we can help implement the underlying system—dashboards, integrations, and automation.

Downtime Cost Calculator

Estimate the real cost of downtime (labour + lost contribution) and see weekly/monthly/annual impact in AUD. Great for making an automation or maintenance business case.

Calculate Downtime Cost

OEE Calculator

Calculate Availability, Performance, Quality and total OEE. Quickly see your biggest loss lever and where to focus first.

Why we publish free tools

Most improvement projects start with a simple question: “How much does this problem cost us?” Tools like downtime cost and spreadsheet ROI help you quantify impact so you can prioritise what to fix first.

If you'd like, we can turn a calculator result into a real solution—production dashboards, data capture, reporting automation, and system integration.

Want another tool? If there’s something you search for regularly (or calculate in Excel), it’s a good candidate.

Looking for something more advanced than a calculator? See NS-GraphRAG (AI knowledge assistant for your documents) or browse all products. If you want help implementing the underlying system, get in touch.

FAQ: Free Tools

Are these tools really free?

Yes. No signup required. Use them internally, share them with your team, and link to them if they're useful.

Can you build a custom calculator or tool for our process?

Yes. If you're calculating something regularly in Excel, it's a good candidate for a lightweight web tool.

Do you offer help implementing the system behind the tool?

Yes. We can build the underlying database, dashboards, integrations and automation so the results are measured automatically—not manually.

Will you add more tools?

Yes. We add new tools when we see common problems worth solving quickly (cost of downtime, reporting effort, manual data entry, etc.).
