Trunk Tools

What Trunk Tools does

Trunk Tools builds the brain behind construction, automating the $13 trillion construction industry. The platform reclaims lost time for builders by organizing vast amounts of unstructured data, automating repetitive workflows, and boosting field productivity using construction-centric AI. It provides a centralized knowledge base for project workflows and documents, empowering workers with Intelligence Augmentation (IA) to ensure the right information is available at the right time. The company's AI team focuses on fusing research-level expertise with real jobsite challenges, utilizing computer vision, NLP, and MLOps to transform construction processes.

Products

• TrunkTextGives teams instant, actionable answers straight from project documents, eliminating the need for manual searching. It syncs with various platforms (Procore, Autodesk, SharePoint, Box, Dropbox, Egnyte) and processes specs, RFIs, submittals, drawings, schedules, contracts, meeting notes, and field reports. It's built for construction professionals and delivers sourced answers in under 30 seconds. It also functions as a Q&A Agent, connecting to preferred software to read, parse, and structure documents into searchable data for accurate answers backed by documentation.
• TrunkSubmittalReviews submittals in seconds, catching product discrepancies from project specifications and trade-related RFIs to ensure confident submissions. It automatically reviews 90% of submittals, flags missing, conflicting, or noncompliant information, and suggests follow-up action items and email drafts. It integrates seamlessly with existing workflows and tools, saving time and preventing revision cycles. It also includes a Discrepancy Detection Agent to catch discrepancies across project documentation before they lead to delays or rework.
• Submittal RegisterA feature of TrunkSubmittal that generates a detailed submittal register in minutes by reading the spec book and building a complete, accurate submittal log, publishing directly to the project management system.
• TrunkReviewAn AI-powered agent that accelerates the process of interpreting changes in drawing revisions, helping teams avoid missing details that can lead to costly rework. It leverages vision language models trained by architects and construction industry pros to scan new revisions, identify clouded and unclouded changes, and produce a visual overlay and bullet point list of changes with links to associated sheets. It acts as a Drawing Revision Agent.
• TrunkBidAn AI agent that automates subcontractor bid leveling, saving estimators hundreds of hours and eliminating costly scope gaps.
• Workflow Automation AgentsAI-powered tools that enable builders to offload manual, administrative tasks. These agents can monitor construction schedules, prepare for meetings, compare project information to standard operating procedures, and more.

AI approach

Trunk Tools uses construction-centric AI, backed by veteran industry professionals, to organize vast amounts of unstructured data, automate repetitive workflows, and significantly boost field productivity. They build AI-powered workflow automation agents like TrunkSubmittal for discrepancy detection, TrunkReview for drawing revision analysis using vision language models, TrunkText for Q&A, and TrunkBid for subcontractor bid leveling. They train their models on deidentified customer data with explicit written permission and oversight by construction industry subject matter experts, focusing on recognizing document types, object detection, and implicit relationships between documents to build a "knowledge graph".
