Online Gantt review
A simple web Gantt editor with dependencies, AI creation, and API automation.
Reviewed by iTechGuides Editors · Editorial team · Updated Sep 2026
Online Gantt is a browser-based Gantt chart application for freelancers, small businesses, and anyone who needs a simple project timeline. The editor covers task scheduling, dependency relationships, milestones, progress tracking, resource assignment, and resource editing. Users can open and save local .gantt files, import and export CSV files, and work through the web interface or API. The basic editor is available without an account, giving smaller teams a straightforward way to create project plans before adding account-based capabilities.
Its strongest distinction is the combination of natural-language AI and automation. The optional AI assistant can create, edit, and analyze Gantt charts through prompts, while the API supports project and task automation. Cloud project saving and sharing extend the workflow beyond local files, and the published category coverage includes workload view alongside dependencies, milestones, and resource management. A 7-day trial is available, while the free editor is described as free forever; cloud storage and sharing, the AI assistant, and Pro features are associated with the Online Gantt Cloud (Pro) plan.
Online Gantt fits users who want a lightweight web charting tool with practical scheduling features and a path to automated workflows. It is a reasonable choice for freelancers, small businesses, and teams that value browser access, simple collaboration, AI-assisted chart creation, or API connections. It is less suitable for project environments that depend on critical path analysis, baselines, or a wider integration ecosystem than Todoist. Those requirements point toward a more specialized alternative, while users seeking a focused Gantt editor with automation support should find the feature mix more aligned with their needs.
