Key highlights of the appMicrosoft Project-style Gantt charts on Jira issues: dependencies cascade on your working calendar, plus portfolios and baselines
Five answers the moment you open a plan
Will we hit the date, what is late or blocked, what changed, what to do next, and can I trust these numbers, on every tab. Each answer opens the facts behind it.
Move one date, the whole chain follows
Drag a bar and every issue that waits on it moves on your working calendar. The Apply review lists each new date before Jira sees it, and Apply writes them issue by issue.
Your words, the plan's numbers
Sponsor reports open on the plan’s frozen numbers. Add your headline, notes and decision requests, leave a line out with a reason, then publish to Confluence as a sealed version.

Your Jira issues become a plan a PM can run: a scheduling engine that reacts like Microsoft Project, not a read-only roadmap.
- Five answers on every plan: will we hit the date, what is late or blocked, what changed, what next, can I trust the numbers.
- Dependencies cascade on your working calendar, with working-day lags and a health check naming what stops the forecast.
- Changes are staged and reviewed before reaching Jira; Apply writes issue by issue and can resume.
- Sponsor reports you edit for internal or external readers, published to Confluence as sealed versions.
- Portfolios, baselines, scenarios, a 0-100 confidence score, a REST API.
- AI (Plan brief, Storyline, Review with AI) on Atlassian-hosted models, on by default, capped daily and monthly.
- Setup backed up on your Jira site, offered back after reinstall.
Runs on Atlassian Forge: plans never leave Atlassian.
