Features
Every part you can point at, and what each one is for.
Drawing the Chart
Five tools on the Gantt toolbar. Each one previews until you let go and Escape cancels before anything commits.
Task Block
Paint work across periods and the task is created and scheduled in the same gesture. Painting away from existing work extends the same block and fills the periods between at zero hours.
Milestone
Place a pure milestone on a date. Draw one on a work row and GanttRight offers a separate independent milestone rather than converting the task.
Paint Completion
Mark periods done by painting over them. Completion is completed periods divided by work periods, kept independent of hours.
Vertical Line
A chart-only annotation for a date that matters. It is explicitly not a scheduling dependency, so it never moves anything.
Eraser
Remove drawn lines, milestones, and completion marks. Work blocks are removed with the Task Block tool or a delete action instead.
Drag and resize previews
Every drag shows the result before you commit it. Release to apply, or press Escape and nothing changed.
Links and the Critical Path
Dependencies you draw and the chain that decides the finish date.
Two connector styles
Gantt Connection Style in Settings changes how arrows are drawn, not how anything schedules. Routed Arrows deliberately shows left-to-right relationships only.
Links that refuse themselves
Pull a link that cannot work and the target hatches red and names the reason before you let go. You are told why, not just told no.
Find Critical Path
One click traces the longest path through the plan and previews it. Nothing is classified until you confirm.
Confirm Critical Path
Commits the Critical and Floating task types and the confirmed path. Regular task dates and row order stay exactly as they were.
Move Critical Path To Top
Lifts the confirmed chain into the upper rows and arranges the floating branches beneath it, without touching dates or classifications.
Auto-Reorganize Tasks Around Critical Path
Composes find, confirm, move to top, and gap closing into one previewed step that applies as a single undo.
The Grid
The columns beside the timeline, most of which you can turn off.
Typing hours and costs straight in
Hours, cost, and completion are editable cells in the row itself. Totals move as you type, with no recalculation to ask for.
Distribute Hours
Enter a total and it divides evenly across the task's existing work cells, including zero-hour periods. Edit individual cells afterward as needed.
Start and Finish date columns
Optional columns, not a required form. Turn them on when you want to read or set exact dates, off when the bars are enough.
Duration column
Shows each task's span in whole periods, spelled out as 1 Day, 2 Weeks, or 1 Month.
Row numbers and WBS
The # column carries row numbers and Work Breakdown Structure identifiers. Move handles stay at the far left whether it is shown or not.
The B/N/R column
Three fixed positions per row: B for Blocked, N for Notes, R for Risks. Click B to focus the blocked reason; N and R open their Task Inspector sections.
Reading the Timeline
Everything that helps you see where the plan actually stands.
Today Marker and Today Line
Two independent settings: an outline around today's period and a vertical line at its left border. Neither draws when today falls outside the timeline.
Zoom
Magnification from 50 to 200 percent, remembered per view. Ctrl and the mouse wheel zooms, Shift and the wheel scrolls sideways. This is display only, never the Time Scale.
Time Scale
Days, Weeks, or Months. It changes what every column stands for, which is why GanttRight asks before moving your work onto it.
Totals Graph
Hours by column, drawn underneath the chart, so a week that quietly holds forty hours is visible rather than inferred.
Resource Load and Lead Totals
Check that nobody is doing three jobs in the same week, before you promise the date instead of after.
Baseline
A read-only snapshot of the chart as it was, to compare against what the plan has since become.
Structure
Shaping the plan rather than scheduling it.
Task cards on the board
One card per job on Task Flow, moved by hand until the order looks right. Click editable card text to type; other areas of the card move it.
Task groups
Wrap a contiguous selection of sibling tasks in a parent without discarding their work. The new group name opens for typing.
Spacer rows
Visual separators between sections of a long plan, so the chart reads in blocks rather than one unbroken list.
Tidy Up Board
Arranges the cards. A card may overlap another partly but can never completely hide it. Clicking an overlapped card brings it forward.
The Record Behind Each Task
The Task Inspector and what leaves the screen.
Task Inspector sections
Task, Schedule, and Connections; Hours and Cost; Notes; Risks. The detail lives with the task rather than in a document nobody updates.
Blocked, with a reason
Mark a task blocked and say why. The reason travels with the task and shows in the B/N/R column.
The risk register
Description, mitigation, likelihood, impact, and state, recorded per task. Open, mitigated, and closed counts show in the section header.
The Project Brief
A paginated report generated from the plan, for the people who will never open the app.
Setup
The parts you set once.
Settings
Theme, alternate row backgrounds, auto cell width, auto fit for task and lead columns, connection style, the project's currency symbol, critical path reminders, and what opens on startup.
Working Calendar
Recurring nonworking weekdays and specific dates, entered one at a time or pasted as a list, including dates outside the timeline.
Favorites
Put the commands you actually use where you can reach them.
Find by task name or lead
Search the plan and step through the matches without losing your place.
