ISOauditor.app is an AI-powered audit assistant and training platform built specifically for ISO lead auditors and certification bodies. The audit assistant scribes and summarises interviews with key personnel in real time, processes documents and audio across multiple formats and 50+ languages, classifies evidence against the relevant ISO clauses, identifies gaps, suggests follow-up questions, and generates accurate, well-written audit reports. Every output is reviewed and approved by the auditor. Developed by ISO lead auditors and technology consultants, trained on thousands of hours of real-world audit data. The training suite pairs clause-by-clause standard knowledge with realistic AI companies to audit each with its own management system, documentation, and a fully responsive AI quality manager trained to behave like a real person. Auditors can practise finding hidden nonconformities, questioning technique, and report writing in complete safety. Available for ISO 9001, 14001, 27001 and 45001, with further standards being added.
