Data Isolation
An AI That Actually Knows Construction
Built for job sites, not just offices. Talk to it, show it your screen, or type — it understands construction and gets things done.
Voice Mode
Talk to your AI assistant hands-free on the job site. Ask about weather, search building codes, dictate task updates — all by voice with construction vocabulary built in.
Screen Context
The AI sees what you see. Capture your screen and ask questions about the data in front of you. No copy-pasting, no context switching.
100+ Tools Built In
Create tasks, schedule events, manage projects, search the web, check weather forecasts, draft emails — the AI handles it all through natural conversation.
Everything Your Crew Needs, One Platform
From project tracking to team scheduling, every tool your operation needs is built in and works together.
Projects
Track every job from bid to closeout. Custom statuses, team assignments, budget tracking, and a full activity feed.
Tasks
Unlimited nesting, board/list/table views, assignees, labels, time tracking, and dependencies.
Calendar
Five views — day, week, month, timeline, and agenda. Drag-and-drop scheduling with tasks and events unified on one calendar.
Org Chart
Drag-and-drop org chart with position-based permissions. Define who sees what by trade and role — not just admin or user.
Team
Invite members, assign positions, manage permissions. Six built-in roles from Owner to Worker with custom overrides.
Contractors Lose Bids Not Because They Can't Do the Work — But Because They Don't Have Time to Estimate Properly
The construction industry runs on thin margins, tight timelines, and relationships built over years. Yet most contractors still manage their business with spreadsheets, disconnected tools, and tribal knowledge. The result? Missed bids, cost overruns, and a team that's always reacting instead of planning.
Proposal Creation Is Slow and Repetitive
No standardized scope library. Every proposal built from scratch. Hours lost on formatting and re-writing instead of winning work. Inconsistent quality across bids means lost opportunities and eroded client trust.
Bad Leads Consume Real Bandwidth
Without automated lead scoring, every inquiry gets the same attention — whether it’s a serious commercial project or a tire-kicker. The feast-or-famine sales cycle persists because there’s no system to prioritize what matters.
Estimates, Actuals, and Outcomes Are Disconnected
Most contractors finish a project and move on. The gap between what was estimated and what actually happened never gets analyzed. Every new project starts from zero — no compounding knowledge, no systematic improvement.
A Platform That Gets Smarter With Every Project
Most software is static. You put data in, you get reports out. Chantro is different. Every project you complete will feed back into the system — refining your estimates, sharpening your processes, and compounding your competitive advantage over time.

“The contractor who learns from every project will always outperform the contractor who starts from zero each time. Chantro makes that learning automatic.”
AI-Powered Estimating That Actually Understands Construction
Traditional estimating means rebuilding from scratch every time. Chantro's AI Estimating Engine will analyze your project documents and generate structured, line-item estimates in minutes instead of hours.
But it won't stop there. Every project you complete will feed back into the engine. Your historical cost data, variance patterns, and regional pricing all inform the next estimate. The result will be an estimating tool that gets measurably better with every project.
- Upload drawings, specs, and scope documents
- AI analyzes against your historical project data
- Generates structured, line-item estimates in minutes
- Learns from every completed project to improve accuracy
- Export-ready proposals with your branding and formatting

Not Just Managing Work — Learning From It
Every project generates data. Most of it gets filed away and forgotten. Chantro's intelligence layer will turn every completed project into a lesson that improves your next one.
See where your estimates diverged from reality. Understand which project types are most profitable. Identify operational patterns that cost you time and money. Over time, Chantro will build a compounding knowledge base that makes every decision sharper.
- Automatic estimate vs actual comparison at closeout
- Variance analysis across labor, materials, and subs
- Project intelligence dashboard with trend detection
- Operational insights that compound over time
- Benchmarking across your entire project portfolio
