ChatGPT, Claude and Gemini hand you the plan as text or a table — where you cannot push a date, flag a milestone or show it to anyone. Bring it over and it becomes a Gantt you edit by dragging.

Paste it this prompt: "Give me the plan as a table with columns Group, Task, Start, End and Milestone, using YYYY-MM-DD dates."
Send that table to .xlsx or .csv from your spreadsheet, or bring the PDF. Only got it on screen? Screenshot it — we read the picture with optical recognition, in your browser too.
Drag the bars to move dates, pull the edges to change how long something takes, and flag milestones. Then export to PDF, PNG or Excel, or hit Share and we copy a link you can hand to anyone.
Understands the column headers your assistant already writes
Your table is never uploaded: it is read and edited in your browser
Fix dates and milestones without prompting the model again
Ends up as PDF, PNG or Excel, in whichever visual theme you pick
This is the column contract we import untouched. Hand the prompt to any assistant and whatever comes back goes straight in.
| Group | Task | Start | End | Milestone |
|---|---|---|---|---|
| Discovery | User interviews | 2026-03-02 | 2026-03-13 | NO |
| Discovery | Scope sign-off | 2026-03-16 | 2026-03-16 | YES |
| Design | Wireframes and prototype | 2026-03-17 | 2026-04-03 | NO |
| Build | Backend and admin panel | 2026-04-06 | 2026-05-15 | NO |
| Launch | Ship to production | 2026-05-18 | 2026-05-18 | YES |
The Milestone column takes YES or NO. Dates work as YYYY-MM-DD or MM/DD/YYYY. Group and Milestone are optional: task, start and end are enough.
Any of the four, and whatever ships next. We never connect to the assistant: we work from the table it handed you, so where you generated it makes no difference.
Ask for the table with Group, Task, Start, End and Milestone columns, and spell out the date format. That is enough — and if it forgets Group or Milestone, the file still imports.
Reply "redo that as a table with those columns" and it rewrites it on the spot. Rather not go back to the chat? Screenshot the answer and we read it with optical recognition. See every format we accept
Yes: hit Share and we copy the link to your clipboard. Whoever opens it gets their own editable copy. You can also send it by email with that link inside. Either way the project rides inside the link, never parked on a server.
No. The file is read, edited and exported in your browser. The one exception is emailing it: that attachment does travel, because there is no other way to deliver it.
