What it is
GanttAI helps specialty contractors locate their work in a general contractor’s schedule and assess what changes between revisions mean for their scope. It opens PDF, MPP, XER, XML or Excel schedules as searchable schedules and identifies relevant activities. Revision comparison covers dates, durations, logic and sequence, with a report link that recipients can view without an account. For crew planning, users enter hours by scope and person-day; GanttAI estimates staffing needs and shows crew peaks against available headcount. Its AI Agent answers plain-English schedule questions and can create look-aheads or summaries as Excel files. The Portfolio plan adds a cross-project view of trade manpower by day, week, month, quarter or year. The subcontractor product describes exports for Excel, Primavera P6, Microsoft Project and PDF. GanttAI is a paid web product with a free trial. The site also offers a free comparison report without requiring a trial or card. GanttAI says customer schedules, drawings and contracts stay in the customer’s workspace and are not used to train another customer’s model.
Who it suits. GanttAI suits specialty contractors who need to find their activities in a general contractor’s schedule and track how revisions affect their work. It also supports teams planning staffing across projects.

Review
GanttAI is a web-based schedule review and crew-planning system for specialty contractors working from general contractors’ programmes. It suits subcontractors who need to identify their scope, quantify revision impact and staff activities; firms seeking broad project-management functions or mobile field apps should look elsewhere.
Overview
GanttAI opens PDF, Microsoft Project (MPP), Primavera P6 (XER and XML) and Excel schedules as searchable programmes, then locates activities in a subcontractor’s scope. Its Compare function checks dates, durations, logic and sequence between revisions and creates a shareable report link that recipients can open without an account. The company claims more than 99% accuracy across those comparison fields.
Crew planning turns hours per scope and person-day inputs into staffing estimates, showing crew peaks against available headcount. GanttAI Agent answers plain-English schedule questions and can export look-aheads or summaries as Excel files. The Portfolio plan adds trade-level manpower views across projects by day, week, month, quarter or year. GanttAI says customer schedules, drawings and contracts remain in the customer’s workspace, are not pooled with other customers and are not used to train another customer’s model.
Key features
Schedule review and comparison
Searchable imported schedules reduce the work of finding a trade’s activities in a general contractor’s file. Revision comparison is the strongest reason to choose GanttAI: it exposes changed dates, durations, dependencies and sequence in a report suitable for sharing with people who do not use the product. Comparing three or more revisions side by side in one view is roadmap work rather than a current capability.
Staffing and portfolio control
Person-day loading connects schedule dates to practical crew requirements, helping a subcontractor spot peaks before committing labour. Portfolio’s cross-project manpower view is more relevant to firms balancing several jobs than to a single-project trade contractor, while the Portfolio plan also includes invoicing, purchase orders and net-30 terms.
AI assistant and file handling
Natural-language questions and Excel exports can shorten routine schedule reporting. Support for common Microsoft Project, Primavera P6, Excel and PDF formats makes GanttAI workable when general contractors use different systems; exports cover Excel, Primavera P6, Microsoft Project and PDF.
Pricing
Single: 250.00 USD per month, with one project, $250 a month for each additional project, unlimited reviews and compares, person loading, crew planning, the AI Agent, Excel and PDF exports, onboarding and support. The yearly option is 2750.00 USD per year; the annual price gives eleven months for twelve, while extra project slots remain billed monthly. This is the clearest fit for one specialty contractor managing a primary job.
Team: 750.00 USD per month for five projects, with extra projects at $150 a month. It adds unlimited users, shared projects and files, an admin console, roles and dedicated support with an account lead. Team yearly costs 8250.00 USD per year, with the same eleven-month-for-twelve pricing and monthly billing for extra slots. Choose it when several staff need controlled access across active projects.
Portfolio: 1250.00 USD per month for ten projects, plus $150 a month per extra project. It includes portfolio crew planning and overview, invoicing, POs, net-30, a named contact and priority support. The yearly plan is 13750.00 USD per year, again priced as eleven months for twelve. The 100.00 USD per month Portfolio Pro add-on adds an editable portfolio crew plan, team and crew management, and projects in the overview without consuming a project slot; its yearly price is 1100.00 USD per year.
There is no free plan. The free trial covers one project, two schedule reviews and one comparison, requires no card and does not auto-charge when it ends. A free comparison report is also offered without a trial or card. Onboarding and support are included on every plan; Team and Portfolio receive dedicated support.
Platforms
GanttAI runs on the web. Its practical platform advantage is format compatibility rather than device coverage: Microsoft Project, Primavera P6, Excel and PDF schedules are supported for import or export.
Who it's for
GanttAI is best for specialty contractors and subcontractors whose work is governed by a general contractor’s changing schedule, especially those coordinating labour across multiple projects. Single-project trades can use the Single plan without paying for portfolio controls. It is a poor fit for users needing schedule templates, a native mobile application or a full general-purpose construction management suite; schedule templates are not provided.
Pros and cons
- Pros: revision reports cover dates, durations, logic and sequence; searchable support for PDF, MPP, XER, XML and Excel; crew peaks are compared with available headcount; share links need no recipient account; privacy controls keep customer files isolated; annual plans reduce the effective price to eleven months for twelve.
- Cons: no free plan; Single costs 250.00 USD per month before extra projects; three-way revision viewing is not live; web-only access excludes native mobile workflows; no schedule templates; Portfolio pricing is substantial for smaller trades.
Alternatives
For a wider shortlist, see Construction scheduling software.
- Buildlr suits teams preferring a value-based fee of 0.36 USD per month, billed as 0.35% of each invoice sent, with no subscription or per-user charge.
- Nialli Visual Planner is the alternative when Android, iOS, macOS, Windows and web access matter; it offers a 30-day full-access trial without a card.
- Pro Crew Schedule is worth considering for a 30-day all-features trial and lower-cost per-user startup pricing.
- Birdog is a project-licensed option at 150.00 USD per month, priced per project rather than per user.
- Touchplan offers custom project packages with unlimited users, mobile access, training and implementation.
- Asta Powerproject is a desktop-oriented choice with a single-user subscription of 695.00 GBP per year, excluding VAT.

Verdict
Choose GanttAI if your specialty-contracting business must audit schedule revisions and align crews with changing dates across one or many projects. Its combination of comparison detail, staffing analysis and shareable reports is unusually focused. Look elsewhere if you need mobile field use, schedule templates, three-way revision views today or a lower-cost general construction platform.
