GanttTime back on site
The two days a month spent red-lining a printout go back to running work. Changes in your scope surface the day the revision lands, not the week your crew shows up to a wall that isn’t ready.

What you get
Built for specialty contractors.
You didn’t write the schedule, but you’re accountable to it. These are the things you actually need.
Review
The GC’s schedule opens up, with the activities in your scope pulled out and manloaded, so you see the crew behind the dates.
Compare
See any two revisions side by side, with every date, duration, logic and sequence change in your scope and what it does to your crew.
Crew planning
Manload the file: set the hours behind each scope and GanttAI works out the crew every activity needs, day by day, against the people you actually have.
Portfolio overview
See every trade on every project in one picture, by day, week, month, quarter or year, so you know where your crews are committed before you bid the next job.
GanttAI Agent
Ask anything about the schedule in plain English and get an answer you can act on, with the working file to go with it.
Look-aheads & exports
Ask for a three-week look-ahead and a ready-to-use Excel lands in the chat. Everything else leaves as MPP, XER, XML, Excel or PDF.
How it works
Schedules, now easy to understand.
One workflow, end to end: unlock the schedule you were sent, find what the next revision did to it, plan the crew behind it, and see that crew against every other job you are running. Pick any part of it.

Final inspection
Turn the GC’s schedule into your own plan.
The GC’s schedule is built to run the whole project. GanttAI pulls out the part you are responsible for, and the crew you need to deliver it.
01
Unlock the file
Upload the schedule the GC sent you, whether it is a PDF, MPP, XER or Excel file. GanttAI opens it as a live schedule, however messy the printout was.
02
Work it like your own
Search any activity, filter to the trades you care about, zoom the timeline in and out. Your schedule is no longer locked in a printout.
03
Find your scope
GanttAI picks out the activities that belong to you and manloads them, so you can see the crew requirement sitting behind the dates.
Export it as MPP, XER, XML, Excel or PDF.
See what each new revision changes in your scope.
When the GC sends a new revision, GanttAI shows you what it changed in your dates and your crew within minutes.
01
Pick two revisions
Choose any two schedules from the same project. GanttAI matches the activities itself, so there is nothing to map by hand.
02
See what changed
GanttAI lists every change to dates, durations, logic and sequence, activity by activity. Filter to a single scope to see only what affects you.
03
See the crew impact, then send it
Resource changes come back as a heat map of who’s needed, and when. The whole report is a link you can send to the GC, your PM or your foreman. They don’t need an account.

Know how many people each activity needs.
A schedule tells you when. It does not tell you how many people you need standing there, which is the number your week actually turns on.
01
Put your hours in
Set the hours behind each scope and subscope, and how many hours one person does in a day. That is the whole setup, and it carries across every revision of that job.
02
Read the crew off every activity
GanttAI works out the people each activity needs from the hours against its duration, and puts the number on the schedule beside it. Put a crew figure on a task yourself and yours wins.
03
Find the peaks before they find you
GanttAI plots the people you need each day against the crew you have, so you can spot stacking and shortfalls while there is still time to fix them.
Crew planning is included on every plan.
See every trade across every project in one view.
Planning one project is manageable. The hard part is knowing whether crews you have committed to one job are already booked on another.
01
Pull every project together
GanttAI adds up the manpower for each trade across all your live projects and shows it in one view, with nothing to export or reconcile by hand.
02
Any period you need
View it by day, week, month, quarter or year. Open a trade to see the projects behind its number.
03
Against the crews you have
Enter your real crew sizes and the view shows utilisation, where you are short, your busiest and quietest months, and when the current commitments run out.
The portfolio overview is included on the Portfolio plan.

Rev 8
Levels 2–4
Rev 8 just landed. What changed for me?
Nine activities in your scope moved. Drywall hang slips 6 days, ceiling grid pulls forward 3, and your peak week goes from 10 people to 14.
Can I hold the crew flat at 8?
Only if tape and finish starts four days later. It has 6 days of float, so the finish date does not move.

Schedules now talk back!
You do not go looking for what changed. You ask, in the same words you would use on the phone.
01
Ask in plain English
No filters to build and no query language to learn. Dates, crew, sequence, float: if the schedule knows it, you can just ask for it.
02
Get deep insights
The GanttAI Agent already knows the schedule you reviewed. Ask questions about resources, about tasks in your scope, about challenges with the proposed dates, or even stacking, and get insights in seconds.
03
Go beyond the chat
Ask for look-aheads or summaries and get ready-to-go Excel files. No more manually filtering and struggling with tools to get the data you need.

Why it pays
Taking back what matters
The schedule analysis still gets done. It just stops eating your week.
20hrsSaved every month reviewing & comparing
99%+Of schedule changes caught
10×Return on investment in month one
30minFrom unreadable file to answers
Better planning
Manloading turns dates into headcount. You see the peak before you promise it, and you see it move the moment the next revision lands.
Fewer disputes
When the change is documented the day it lands, the conversation is about the schedule rather than about who remembers what. The report is the record.
Q&A
Questions from subcontractors
Is our data private?
Yes. Your data is fully private and never exposed. Your schedules, drawings and contracts stay in your workspace, are never pooled with other customers, and never train anyone else’s model.
How reliable are the findings?
Compare is >99% accurate across dates, durations, logic and sequence. Review catches 80–90% of your scope on a schedule it has never seen, and it is trainable. By the second revision of that schedule it is at 99%+.
What file types can we upload?
You can upload PDF schedule prints, including messy ones, as well as Microsoft Project (.MPP), Primavera (.XER, .XML) and Excel files.
What can we export?
You can export to Excel, Primavera P6, Microsoft Project and PDF. Look-aheads come straight out of the chat as a ready-to-use Excel file.
Does it need the GC’s logic to work?
No. Without logic you still get a live, searchable schedule, your scope pulled out, manloading and full comparisons. With logic you also get dependency questions and what your work is waiting on.
Which revisions can we compare?
You can compare any two versions of a project, as often as you like. Pick one as the baseline, pick the one you want to check it against, and run it again every time the GC sends another revision. Comparing three or more side by side in one view is on the roadmap, not live today.
What do we need to set up crew planning?
You need two numbers for each scope: the hours behind it and the hours one person works in a day. GanttAI derives the crew each activity needs from those against its duration. Put a crew figure on an activity yourself and yours is used instead.
Can we see our crews across all our jobs?
Yes, on the Portfolio plan. The overview adds up trade-level manpower from every live project and shows it by day, week, month, quarter or year, against the crew sizes you actually have, so you can see utilisation and where you are short before you bid the next job.
How does pricing work?
You pay per project, from $250 a month. A project is one GC schedule and all of its revisions, and within it reviews, comparisons, crew plans, look-aheads and exports are unlimited. See the plans.
