- Expensive project management software with a 6-week learning curve

What Makes LoopGantt Different
Two-Pass AI Generation
LoopGantt doesn’t just generate a schedule — it verifies it. The first AI pass creates your project plan with tasks, durations, and dependencies. The second pass reviews the output for logical errors, circular dependencies, and unrealistic timelines. The result is a schedule you can actually trust as a starting point.
4 Dependency Types
Support for Finish-to-Start, Start-to-Start, Finish-to-Finish, and Start-to-Finish dependencies — the same four types used by enterprise scheduling tools. Click between any two tasks to create a dependency, and watch the schedule auto-adjust when you move things around.
Critical Path Analysis
LoopGantt automatically calculates and highlights the critical path — the longest chain of dependent tasks that determines your project’s minimum duration. Change a task on the critical path and you’ll see the impact on your end date instantly. Float values show you how much slack non-critical tasks have.
Kanban + WBS Sync
Every Gantt chart automatically syncs with a Kanban board and a Work Breakdown Structure diagram. Move a task to “In Progress” on the Kanban board and the Gantt chart updates. Nest tasks under phases in the WBS tree and see the hierarchy reflected in your timeline. One project, three views.

Frequently Asked Questions
How does the AI Gantt chart maker work?
Describe your project in plain English — for example, “Build an e-commerce website with 3 developers over 4 months.” LoopGantt’s AI analyzes your description and generates a complete Gantt chart with tasks, durations, dependencies, and milestones. The AI uses a two-pass system: it first generates the schedule, then verifies it for logical consistency. You can also choose from 24 industry-specific templates or build your chart from scratch with drag-and-drop.
How accurate is the AI-generated schedule?
LoopGantt uses a two-pass verification system. The first AI pass generates your schedule, and the second pass reviews it for logical errors, missing dependencies, and unrealistic durations. The result is a professionally structured schedule that serves as a strong starting point. You can then fine-tune individual task durations, adjust dependencies with drag-and-drop, and customize the timeline to match your specific project needs. The AI is domain-aware and adjusts its output for software projects, construction, events, marketing campaigns, and more.
Is the Gantt chart maker really free?
Yes. The free tier includes up to 3 projects with unlimited tasks per project, interactive Gantt charts, critical path analysis, 2 AI generations per day, cloud storage, and PNG/PDF export. No credit card is required to sign up. The Pro plan ($5.99/month or $49.99/year) adds unlimited projects, project baselines and variance tracking, custom work calendars, Word and Excel export, and premium export templates.
What export formats does LoopGantt support?
Free users can export their Gantt charts as PNG images and PDF documents. Pro users additionally get Word document export (.docx), Excel Gantt export (.xlsx), and access to premium export templates with multiple layout options including compact, standard, and executive styles. All exports include your complete project timeline, task details, progress indicators, and dependency relationships. You can also import and export project data as JSON or CSV.
Can I use LoopGantt offline?
LoopGantt is a web-based application that works in any modern browser — Chrome, Firefox, Safari, and Edge. You need an internet connection for AI generation and cloud synchronization. However, the Gantt chart editor loads quickly and works smoothly with minimal bandwidth. Your projects are automatically saved to the cloud, so you can access them from any device — desktop, tablet, or phone. There is no software to install or update.
