GanttPilot

Scheduling tools have long separated the drawing from the logic: you arrange bars on a canvas, the tool never tells you when the arrangement is wrong. GanttPilot combines prompt-based schedule generation with a CPM engine that actively checks dependencies, deadline pressure, and resource load. The core workflow runs in four steps — generate a first-draft schedule from a prompt, template, or imported file; run a dependency and deadline check; describe what changed in plain language; review the impact preview; then approve or reject the revision. Nothing updates without explicit approval.

The change-preview feature is where GanttPilot separates from simpler Gantt generators. When a client approval shifts by five days, the tool surfaces every downstream task affected, shows the before and after dates, and flags whether the final milestone is still protected — before a single date changes in the schedule. That preview-then-approve loop is what the vendor positions as the core contract with the planner: the AI suggests, you decide.

The tool fits solo planners and small teams running discrete projects with defined start and end dates — product launches, construction and installation sequences, shutdown recovery, and client handovers. It is not a portfolio management layer. A team running eight concurrent projects with shared resources across all of them will hit the single-schedule model quickly. There is no API and no self-hosted option described on the vendor page, which rules it out for teams that need to embed scheduling logic inside a proprietary platform or keep project data on-premises.

Import paths include Excel and MS Project XML, which covers the most common handoff formats in construction and industrial planning. The vendor page describes a credit-based generation model, with a paid-only tier removing those constraints for teams that need to iterate frequently through revisions.
