From the shop-floor "why?"
to the root cause
— just by talking with AI.
The diagram grows as you chat. AI digs into causes grounded in your internal documents, then exports 8D corrective action reports in one click.
Paper, Excel, and dependence on the one person who can write it. Root-cause analysis always lands heavy on someone.
Reports stuck on paper
Handwritten forms get lost and transcription lags. Analysis often lands weeks after the incident.
Scattered information
Safety data is spread across Excel, email and cabinets — you never see the whole picture.
Always reacting
With no real-time signals, you fight fires after the fact instead of preventing them.
Heavy on one person
Few people can write the whys, and formatting a report takes half a day. Prevention quality becomes person-dependent.
Just talk — and the diagram grows on its own.
"Dig deeper into equipment" — one line, and AI rewrites both the occurrence and outflow branches, grounded in your documents, to submission-ready depth.
30-second incident reports
Report from the field with a QR code. No app, no login required.
Internal-document grounding
Ingest standards and past cases; AI cites them as sourced evidence. Knowledge builds as you use it.
8D report in one click
From a finished analysis, auto-generate an Excel report ready for audits and customers.
Countermeasure dashboard
Manage actions with owners and due dates. See completion and overdue at a glance.
When the analysis is done, so is the report.
Customer corrective action reports and ISO/IATF audit responses — the half-day formatting job, reduced to one click.
- Full D1–D8 format: occurrence/outflow whys, root causes, countermeasures and deployment pre-filled
- Excel output, so adjusting to your customer's template is straightforward
- Pending fields (effectiveness check, approval) are left blank for completion
No sign-up required. This shows a completed example — fields like team and effectiveness check are exported blank for you to fill in.
