The Root Cause Analyzer
8D and CAPA investigations with the rigor a reviewer looks for: evidence before conclusions, alternatives ruled out on the record, and it will not let you stop at operator error.
Run a full investigation free. Your experts make the call.
Why this exists
Most CAPAs don't hold up under an audit. The elements reviewers look for (verified causes, alternatives ruled out, evidence citations, real effectiveness checks) take senior quality engineering experience most organizations cannot keep on staff. And generic chatbots make it worse: they encourage the jump to conclusions, agree with your pet theory, invent plausible causes, never challenge your information, and blame the operator. This tool is built to stop exactly that. It walks you through the investigation the way a senior quality engineer would. You decide it's good to go and sign off. The tool never certifies your result.
Evidence before conclusions
No root cause statement until the evidence is on the table. Evidence against the theory gets asked for before anything is confirmed. IS/IS-NOT before 5-Why.
Your experts stay in charge
It is a decision support aid, not the investigator of record. A qualified person in your organization reviews and approves the result before use.
A price you can approve
Flat pricing per deliverable ($79 to $129, shown below), and you can start free. Never a metered token bill. You see the price before you start.

Run any investigation free today and see the result on screen. No subscription. Pick a tier only when you want the record. The higher tiers run a deeper investigation (more phases, a verification experiment) and produce the more formal record.
The conversation is the receipt
Every published sample ships with the full engineer↔tool conversation behind it, including the moments the tool rejects a planted wrong theory. Same defect, three deliverables, each with the full conversation behind it.

The tool is also the proof behind the consulting: I built it and proved it with the same discipline I bring to client workflows. See the AI Control Plan or the consulting practice.
