Diagramium vs Ganttic

Diagramium is a web-based Gantt chart maker for creating project schedules and presenting them step by step. Charts can include tasks, dependencies, milestones, progress, a highlighted critical path, and a Today marker. Timelines use calendar dates or project days with Daily, Weekly, or Monthly scales. Present mode reveals tasks sequentially and can add AI voice narration, subtitles, and speaker notes for each step. After loading, the browser editor works offline. Charts remain in browser storage and exported files; the privacy policy says content is not uploaded, no cookies are set, and no third-party analytics are used. PNG, SVG, and PDF exports do not require an account. Animated GIF, video, and animated SVG exports require a free Google sign-in account. Clearing site data can permanently delete unexported local charts.
