ChatMPP vs MPP Viewer

AI Copilot for MPP Projects ChatMPP is an AI-powered copilot designed to help teams and stakeholders instantly understand, summarize and query MS Project (.mpp) files using natural language. ChatMPP works with native Microsoft Project files and supports .mpp files created with Microsoft Project 2010, 2013, 2016, 2019, 2021 and 2024. Unlike general-purpose AI tools, ChatMPP is specifically optimized for the structure and data inside Microsoft Project plans, enabling more accurate and context-aware analysis of tasks, milestones, critical path, dependencies, resource workloads, baselines, delays, costs and remaining effort. With ChatMPP you can quickly get plain-language summaries of complex project plans, ask ad-hoc questions about dates, resources, risks or workload, generate status updates and executive summaries ready to copy-paste into emails or reports, identify overallocations and upcoming bottlenecks, and help non-project-management stakeholders understand the plan without needing Microsoft Project installed. We pioneered the development of Project Viewer for MPP files back in 2001 and since then we have helped millions of users instantly save money on Microsoft Project licenses. ChatMPP builds on this long-standing expertise with Microsoft Project files, adding a modern AI copilot layer that makes your project data easier to understand, explain and act on. You can start using ChatMPP for free with core viewing and Q&A capabilities on your .mpp files. By upgrading to ChatMPP Plus, you can unlock extended usage limits and advanced features such as deeper analysis, richer summaries and enhanced collaboration scenarios. ChatMPP transforms the way you read, understand and communicate your Microsoft Project plans. Payment will be charged to iTunes Account at confirmation of purchase.
