How Can We Help You?

Clone or download the repo from GitHub (https://github.com/carthworks/gantt-pro), navigate to chrome://extensions/ in your browser, toggle "Developer mode" in the top-right, click "Load unpacked", and select the project folder.

Yes! Gantto has a full standalone web application available at https://gantto.vercel.app/ that runs completely in your browser with offline localStorage persistence.

Open the task creation modal, type your task in conversational English (e.g., "Design marketing landing page from tomorrow for 5 days at 40% progress"), and click "Parse & Fill Form". Gantto extracts the title, start date, duration, and progress bracket automatically.

Critical Path Method calculates the longest continuous chain of dependent tasks with zero slack time. Gantto highlights this critical sequence so you instantly identify project bottlenecks and sequence delays before delivery dates are impacted.

Gantto includes templates for Software Development Lifecycle (SDLC), Product Marketing & Launch Campaign, Event Planning & Production, and Design Sprint & Prototyping. You can also save custom project templates.

100% of your data is stored locally in your browser using Chrome Storage API (chrome.storage.local) or localStorage fallback. Your data never leaves your device and is never sent to third-party servers.

Gantto supports full JSON data backup and restore for data portability, direct CSV export for Microsoft Excel, Google Sheets, or Notion, and presentation-ready print stylesheets for PDF exports.
