Hi Product Hunt! I'm Haroldo, and I built Great Gantt because I spent years rebuilding the same spreadsheet timeline every time something slipped. It's the tool I wished existed back then.

What it does:

• You describe the project in plain words and AI drafts phases and tasks

• Tasks are linked, so when one slips everything after it moves too, in business days, with your holidays

• Critical path, baselines and an S-curve to see if you're on track

• Export to Excel or PDF when someone asks for "the spreadsheet"

There's a demo you can play with without signing up: https://www.greatgantt.com/en/demo

The free plan covers one active project. I'd love your feedback, especially on what's missing for how you plan projects today.
