Trunk Tools: AI Workflow Automation for Construction Teams

Overview

**Trunk Tools** builds an AI assistant that automates document-heavy construction workflows for project teams. The platform ingests specs, RFIs, submittals, drawings, schedules, contracts, meeting notes, and field reports—then answers questions with citations, flags discrepancies, and automates routine reviews. It live-syncs with existing systems like Procore and Autodesk Construction Cloud, so teams don’t have to change tools.

Note: Independent, in-depth third-party reviews (e.g., G2/Capterra) remain limited; buyers commonly request accuracy demos on messy PDFs and change-heavy jobs.

Competitive Landscape and Differentiation

Competes adjacent to construction platforms with AI features like Procore and Autodesk Construction Cloud.

Specialized peers include Document Crunch, Buildots, Foresight, and Beam AI.

Differentiators:

**Depth on construction paperwork** and schedule literacy

**Multi-format OCR** and **RAG grounded** in project files

**Targeted agents** for schedule and document workflows

**Layered deployment** that fits existing PM systems rather than replacing them

Pricing and Buying Process

No public pricing or free trial listed; typical motion is to **book a demo**.

For procurement: request product scope, security documentation, and integration details.

Security Notes

No publicly available, detailed security page or explicit SOC 2 claim was found during this review—treat as “ask vendor.”
