Three connected tools — Ishikawa fishbones, 5 Whys, and one-page A3 reports — with AI assistance and cloud-saved projects. Go from "something's wrong" to a documented, shareable root-cause story.
We turn chaos into clarity — and plans into results.
Each tool stands on its own — but together they form a clean path from brainstorm to documented root cause.
Brainstorm candidate causes across 6M or HOP categories, cluster related ideas, and let AI suggest causes you might have missed.
Drill a chosen cause to its root — linear or branching — with an AI check that flags symptoms vs. true root causes, plus corrective actions.
Assemble a one-page PDCA story that pulls in your fishbone and 5 Whys, then print straight to a polished PDF for review.
Built for engineers, quality, operations, and continuous-improvement teams who run real RCAs.
Suggests next questions, drafts countermeasures, and spots duplicate or shallow causes.
Carry one analysis from fishbone to 5 Whys to A3 without re-typing.
Cloud projects follow you across devices — no more lost browser files.
Export print-ready A3 PDFs and JSON for handoff and audits.
