A serious planner. Private by design.
Everything teams expect from a high-end Gantt tool — plus an AI assistant that does the work — running entirely on your own machine.
Interactive Gantt timeline
A fast, drag-and-drop timeline that schedules the way real work does.
- Drag to reschedule, resize to re-estimate — working-day aware
- Parent tasks roll up their children's dates automatically
- Week and month zoom, with a mini-map to navigate big plans
- Unscheduled tasks stay visible as placeholders, never lost
Built-in AI assistant
A real assistant that edits your actual chart — on your own API key.
- Plan a project, draft tasks, or restructure from a sentence
- Level overloaded people and surface schedule risks
- Bring your own provider and key — point it at a local model
- Prompt templates and @ / # / > mentions for tasks and people
Dependencies & critical path
Link work, keep the gaps you set, and see what actually drives the deadline.
- Finish-to-start and the other three dependency types, with lag
- Moves cascade through the schedule and preserve per-edge gaps
- Critical Path Mode lights up the chain that sets your end date
- Conflicts are detected and flagged, not silently absorbed
Allocation & overload
See who is overbooked before it becomes a missed deadline.
- Per-assignee workload as a percentage, with an over-100% badge
- On-bar allocation bands and hatched conflict segments
- Group the timeline by assignee for a resource view
- One click from an overload to an AI leveling suggestion
Baselines & variance
Snapshot the plan, then measure reality against it.
- Capture a baseline at any moment
- Track drift with a variance KPI as work moves
- Restore from a baseline when reality diverges
Export anywhere
Hand the plan to any room in the format it expects.
- Excel (.xlsx) with a colored-cell Gantt view, CSV, and lossless JSON
- MS Project (.xml) and MS Planner — no Java required
- Native PowerPoint and a vector PDF report
Real-time collaboration
A team workspace that updates live, with the right guardrails.
- Live updates across the team as tasks change
- Manager and member roles, scoped to their own team
- An in-app notification feed and task comments with @mentions
Local-first & private
All of the above, running on your machine — not someone else's cloud.
- Your projects live in a file you control; works fully offline
- No telemetry, no phone-home, integrity-verified builds (checked at boot)
- Offline, public-key license check — no activation call to us
Straight from the app
Not a concept — the real thing
These are GanttPulse's actual views, rebuilt from the real app — not mockups. And the real thing moves: watch the AI build a plan and tour every feature on it.
