# Pathline Project Planner

[Zovo](https://theopenapps.com/publishers/zovo) Productivity

ChatGPT Apps SDK New [Tasks & to-dos](https://theopenapps.com/tags/tasks) [Automation & workflows](https://theopenapps.com/tags/automation) [Slack](https://theopenapps.com/tags/slack)

Project planning tool for critical path calculations. Provide task durations and finish-to-start dependencies to compute project duration, earliest/latest start and finish offsets, total slack and slack before immediate successors, all critical tasks and connecting edges, and one illustrative longest chain. The interactive widget filters critical tasks and lets you edit a duration; the task schedule downloads as CSV. Multiple parallel critical chains are preserved. Durations use integer thousandth-unit arithmetic. Supports one to forty tasks and at most 160 links. Offsets start at zero; no calendar dates, holidays, resource leveling, lags or deadlines. CSV links expire in about one hour.
