A Gantt chart maker and project timeline planner that works inside the chat. List your tasks with durations and dependencies and a start date, and Zovo Project Timeline builds the schedule with the critical path method (CPM): early start, early finish, late start, late finish and total float for every task, the critical path, your milestones and the project completion date. Plan on business days that skip weekends and the public holidays of the country you choose (with regional holidays, local weekends such as Friday-Saturday where they apply, and your own days off such as a year-end shutdown), or on plain calendar days. Durations can be given in days or weeks. Dependencies are finish-to-start and can carry a lag ("Design+2") or a lead ("Build-3"); tasks can have a start-no-earlier-than date, an owner, and zero-length milestones. The interactive Gantt chart has a day and week time axis, task bars, dependency arrows, the critical path in red, float shown after each bar, milestones as diamonds and a today line. On a phone the chart scrolls sideways while task names stay pinned. Tap any task for its dates and float, and test what happens if a task slips: the new end date and critical path appear in the card. Ask what-if questions in the chat too, for example how many days a slip moves the finish and which tasks become critical; Zovo Project Timeline compares up to four scenarios against the plan. Downloads: a CSV schedule for spreadsheets, an .ics calendar file with milestones and task start dates, and an SVG image of the Gantt chart for slides and documents. The schedule is computed deterministically, so the same inputs always give the same dates. Dependency loops and references to tasks that do not exist are explained in plain language, naming the tasks involved. Limitations: finish-to-start links only (no start-to-start or finish-to-finish), whole-day scheduling without resource levelling, costs or progress tracking, and plans are not saved or synced with project tools.
