Hey Product Hunt! I’m one of the co-founders of Contrat.io: a tool to simplify AEC document reviews. If you’ve ever coordinated design drawings, submittals, or change orders across multiple disciplines, you know the drill: long email chains, version mix-ups, and manual CRS spreadsheets. It slows projects and hides accountability. What Contrat.io does - Real-time collaboration on PDFs—reviewers and authors work together without version confusion. - Comment Review Sheet (CRS) automation—capture comments, replies, statuses, and responsibilities automatically. - Built-in approvals—route for sign-off without extra tools, then export summaries to PDF/XLS for records. - Designed for AEC—works well for infrastructure, energy, transportation, water & utilities, and more. Who we are We’re engineers with 20+ years in EPC. We built what we wish we’d had on past projects: clear reviews, fewer cycles, faster approvals. How you can help - Tell us which part of your review flow is the biggest time sink. - What integrations or exports would be most valuable? Thanks for checking us out and excited to hear your feedback. We offer a 30-day free trial - no credit card required.
