What Plinth helps you manage

Plinth gives engineers and project leads a focused planning layer beside the CalculationX calculation apps. Use it to keep design tasks, checks, assumptions, deadlines, progress, and follow-ups visible while the technical work moves forward.

Cloud boards

Create separate boards for projects, proposals, QA plans, submittals, and client follow-up, then reopen them from your account.

Access and sharing

Invite board members directly or use workspace access when everyone in the workspace should be able to open the board.

Schedule review

Use calendar and Gantt views to understand date ranges, near-term deadlines, and dependency-driven blockers.

Progress visibility

Track completion, due-this-week work, overdue tasks, blocked tasks, assignee workload, milestones, and critical path items.

From task list to schedule

Plinth is intentionally lightweight: enough structure to keep engineering work moving, without turning a quick delivery plan into administration.

Create tasksAdd the work items, calculation checks, or coordination items that need to be tracked.

Assign responsibilitySet assignees, task groups, priorities, tags, and date ranges for each task.

Link dependenciesConnect blocked work so the Gantt and Progress views show what must happen first.

Review progressUse List, Kanban, Calendar, Gantt, and Progress views depending on the meeting or workflow.
