RCA Studio is a ReliabilityMaster tool for reliability, maintenance and process engineers. Build a root cause analysis as a logic tree: start from the failure event, branch into hypotheses, plan the verification that confirms or negates each one, and turn the confirmed physical, human and latent roots into a corrective action plan.

• Logic tree — failure modes and hypotheses laid out as a numbered tree you can rearrange by dragging.
• Build it with your favourite AI — copy the LLM template into ChatGPT, Claude, Gemini or any assistant with your incident details, then import the tree it drafts. Send an analysis back to the assistant as JSON to review it.
• Hypothesis verification — assign verification actions and mark each hypothesis confirmed, negated or unvalidated.
• Corrective action plan — owners, due dates, priority and status for every action, with overdue items flagged.
• Reports and export — share an HTML report with the tree diagram, or export CSV, JSON and PNG.
• Private by design — no account and no server: your analyses stay in your browser.
