Macabacus launched Deck Check AIR, an AI-powered presentation review tool embedded in PowerPoint, alongside a report finding that artificial-intelligence errors are reaching clients and internal decision-makers. The report found that 87% of companies use AI daily or weekly for financial models and client presentations, while only 23% have comprehensive safeguards covering approved tools, accuracy checks, brand compliance and review workflows. Sixty-two percent of respondents believe an AI-generated error reached a client or internal decision-maker during the past 12 months, and 46% said an error probably entered a deliverable undetected. Deck Check AIR reviews complex financial documents, supports Anthropic, OpenAI and Gemini models, and can be added to Enterprise deployments; Macabacus said it does not use customer data to train its AI models or see, store or retain customer intellectual property.
