GanttAI runs three tools that convert plain-English project briefs into full construction Gantt charts, flag delay risk in uploaded schedules, and compare baseline versus revised versions to surface every deviation. It trains a private machine learning model per customer instead of relying on a shared industry baseline, and operates web-only through app.ganttai.com.
About GanttAI
GanttAI is a construction scheduling tool built by Intelli Construction Inc., a two-person Toronto startup founded in 2023 by former Loblaw Companies construction executive Chirag Soni. It targets manual CPM (critical path method) scheduling, which is slow and error-prone, and which GanttAI's own marketing pegs at causing up to 20% in project cost overruns. GanttAI is built for general contractors, specialty and trade subcontractors, construction consultants, and project owners who want a faster first draft than scheduling by hand in Primavera P6 or MS Project. It has no confirmed integration with either tool and no public API, so most current use looks like a standalone authoring and audit step rather than a plugged-in part of an existing project controls stack. GanttAI presented at BuiltWorlds' AI/ML Conference Demo Day in Atlanta in February 2025, its only confirmed press appearance so far. As of 2026 it has 2 employees, no disclosed outside funding, and no reviews on G2, Capterra, or Trustpilot, though its per-company private model training is a genuine point of differentiation from larger, better-funded rivals.
Pricing
No public pricing. Access is demo-gated: prospects book a 30-minute demo via the founder's Calendly before seeing any plans or costs. No confirmed free tier or trial.
Key Features
- Generate Schedules: Converts a plain-English project brief, such as a 10,000 sq ft warehouse build with a $10M budget, into a full Gantt chart with tasks, durations, and dependencies.
- Review Schedules: Flags anomalies and delay risks in an uploaded construction schedule by comparing it against machine learning models trained on historical project data.
- Compare Schedules: Uploads a baseline and a revised schedule side by side and instantly surfaces every deviation between the two versions.
- Private model training: Lets a company train its own machine learning model on its own historical schedules instead of relying on a generic industry-wide baseline.
- Time savings claim: The vendor states GanttAI can cut schedule development time by up to 70% compared to manual CPM scheduling.
Pros
- The headline time-savings claim is the product's main pitch, but it comes from the vendor alone with no independent benchmark confirming it.
- Company-specific historical training data personalizes risk predictions instead of a generic industry benchmark.
- Founder brings direct construction executive experience (Senior Director, National Construction at Loblaw Companies) rather than a pure software background.
Cons
- No public pricing behind a mandatory sales demo, slower than self-serve competitors that publish plans openly.
- No third-party reviews on G2, Capterra, or Trustpilot as of 2026, so buyers cannot verify claims against a public track record.
- Team of only 2 employees and no disclosed funding raises real questions about long-term support versus better-funded rivals.
Frequently Asked Questions
How much does GanttAI cost in 2026?
GanttAI keeps pricing off its website entirely; the only way to see plans or costs is to book a demo with founder Chirag Soni. No per-seat, per-project, or flat monthly figures have leaked through reviews, press coverage, or comparison sites like Tracxn. Buyers should treat that sales conversation as a required step before they can compare cost against funded rivals such as ALICE Technologies.
Is GanttAI free to use?
No free tier or free trial has been confirmed for GanttAI. Because pricing is not published, it is not possible to confirm whether any limited free usage exists behind the vendor's demo gate. Buyers who want a self-serve free plan should look elsewhere and treat GanttAI's demo as a paid-track evaluation only.
What are the best alternatives to GanttAI?
ALICE Technologies is the more established alternative, using combinatorial AI to simulate scheduling options for large, complex builds after raising $61.1 million in funding. Fyld, which raised $41 million in February 2026, targets AI-driven field operations and scheduling with a larger funded team. nPlan instead focuses purely on forecasting delay risk from historical schedule data rather than generating a schedule from scratch.
How does GanttAI compare to ALICE Technologies in 2026?
ALICE Technologies has raised $61.1 million and uses combinatorial AI to simulate thousands of scheduling scenarios for large, complex builds, giving it a track record with major general contractors. GanttAI, a 2-person team with no disclosed funding, instead emphasizes natural-language schedule generation from a single project brief and lets a company train a private model on its own historical data. Contractors running large-scale builds with budget for an established vendor should lean toward ALICE; those wanting a fast first-draft schedule from plain English should try GanttAI's demo.
How do you get started with GanttAI?
Getting started means booking a demo through founder Chirag Soni's Calendly page, since GanttAI has no public signup or self-serve trial. During that call the vendor walks through pricing and can begin ingesting a company's own historical schedules to train a private model. Contractors can also watch the product generate a sample Gantt chart live from a plain-English project description before deciding whether to move forward.
