What is Atarim?

Atarim's AI experts now propose changes to live pages as drafts, and the app runs on phones.

Atarim 5.1.4 extends the draft-first rule from new pages to edits on live pages: an AI specialist's fix comes back as a draft copy with a preview link, and the task waits in Pending review until a person approves it. Atarim now also works on phones and tablets and installs as an app. The previous release, 5.1.3, rebuilt Boards with a timer on every stage.

What is GanttProject?

A desktop Gantt tool on a multi-year cadence, tethering itself to its own cloud

GanttProject is a desktop project scheduling application released every one to three years, with occasional build-only tags in between. The most recent feature update, 3.3, added calculated columns driven by SQL expressions in the task table, project-relative week numbers, and a native Apple Silicon package. The intervening tags are packaging work rather than product: restoring Linux and Windows builds, and producing both Intel and Silicon macOS packages.

Atarim vs GanttProject: editorial side-by-side

A5.0

Atarim's AI experts now propose changes to live pages as drafts, and the app runs on phones.

◆ Current state

Atarim 5.1.4 extends the draft-first rule from new pages to edits on live pages: an AI specialist's fix comes back as a draft copy with a preview link, and the task waits in Pending review until a person approves it. Atarim now also works on phones and tablets and installs as an app. The previous release, 5.1.3, rebuilt Boards with a timer on every stage.

◆ Where it's heading

Atarim keeps pairing more AI autonomy with more human control: readable memory in 5.1.2, stage clocks in 5.1.3, and now mandatory approval on live changes. The mobile app moves that approval step to wherever the agency owner is, which fits a model where AI does the work and people sign off.

◆ Prediction

Expect approval and review to tie into Boards, for example pending AI drafts showing up as a stage with its own clock.

G0.0

A desktop Gantt tool on a multi-year cadence, tethering itself to its own cloud

◆ Current state

GanttProject is a desktop project scheduling application released every one to three years, with occasional build-only tags in between. The most recent feature update, 3.3, added calculated columns driven by SQL expressions in the task table, project-relative week numbers, and a native Apple Silicon package. The intervening tags are packaging work rather than product: restoring Linux and Windows builds, and producing both Intel and Silicon macOS packages.

◆ Where it's heading

The through-line since 3.0 is a desktop application acquiring a service tail. GanttProject Cloud arrived in 3.0 alongside a bundled Java runtime and an update channel, 3.1 added a connection toggle and pulled a shared human-resource database from the cloud, and 3.2 rewrote the task table with filtering and non-destructive sorting. By 3.3 the table is programmable through SQL expressions. Each release deepens either the cloud tie or the table, which are the two places a desktop planner can still differentiate — but the cadence means any given year may show only a packaging fix.

◆ Prediction

Expect the next feature release to extend calculated columns or the cloud collaboration surface; on this cadence it is unlikely to arrive quickly, and the entries give no indication of timing.
