What is Clarizen?

Planview AdaptiveWork (formerly Clarizen) shows version timeline 2026.02→2026.03, but the visible feed is mostly customer success portal navigation.

The captured Planview AdaptiveWork feed is dominated by customer success portal cards — Connect 2026 conference promotion, UX Research Lab participation, system status links, and the Success Accelerator program. The one release-relevant page is the AdaptiveWork Release Notes index, which shows version timeline markers for 2026.02 (current) and 2026.03 (upcoming 'NEXT RELEASE') but the crawler is capturing the index rather than the per-release detail pages.

What is Plane?

Plane ships a fortnightly digest, and the AI layer is where the real work is going.

Plane releases on a strict twice-monthly cadence, each entry a bundle rather than a single feature. The current window covers Pages becoming a document surface (toggle blocks, embedded widgets, nested-page zip export), Intake getting dashboard visibility, and Automations extending to modules, milestones, and releases. Underneath, Plane AI has been accumulating capability faster than any other area — Skills, an AI Block in Pages, live PQL results in chat, open-weight model options.

Clarizen vs Plane: editorial side-by-side

Clarizen logo0.0

Planview AdaptiveWork (formerly Clarizen) shows version timeline 2026.02→2026.03, but the visible feed is mostly customer success portal navigation.

◆ Current state

The captured Planview AdaptiveWork feed is dominated by customer success portal cards — Connect 2026 conference promotion, UX Research Lab participation, system status links, and the Success Accelerator program. The one release-relevant page is the AdaptiveWork Release Notes index, which shows version timeline markers for 2026.02 (current) and 2026.03 (upcoming 'NEXT RELEASE') but the crawler is capturing the index rather than the per-release detail pages.

◆ Where it's heading

Without substantive release content visible, product trajectory isn't observable from this feed. The continued AdaptiveWork branding reflects Planview's post-Clarizen-acquisition consolidation. Connect 2026 promotion suggests an upcoming customer event in late spring or summer.

◆ Prediction

Confident predictions aren't possible from this slice. A different ingestion target (per-version pages under success.planview.com/Planview_AdaptiveWork/00_AdaptiveWork_Release_Notes/...) would surface actual release content and let trajectory and prediction become real.

Plane logo6.3

Plane ships a fortnightly digest, and the AI layer is where the real work is going.

◆ Current state

Plane releases on a strict twice-monthly cadence, each entry a bundle rather than a single feature. The current window covers Pages becoming a document surface (toggle blocks, embedded widgets, nested-page zip export), Intake getting dashboard visibility, and Automations extending to modules, milestones, and releases. Underneath, Plane AI has been accumulating capability faster than any other area — Skills, an AI Block in Pages, live PQL results in chat, open-weight model options.

◆ Where it's heading

The tracker is being rebuilt around two things it did not start as: a wiki with executable blocks, and a workspace where agent behaviour is authored and stored. Skills was the turn — instructions saved once and reused rather than re-typed — and the Pages work since has been about making the document a place where that output lands. The structural cleanups run alongside: epics folded into the work item type system, permissions redesigned into two layers, automations widened to more object types. It is consolidation, not sprawl.

◆ Prediction

The next digests likely extend Automations toward AI-triggered actions, since Skills, PQL, and rule-based automation now exist as separate pieces that obviously compose. The entries are digest summaries linking off-site, so per-feature depth is not readable from the feed.
