What is Backlog?

Backlog ships steady Gantt and chart refinements, but the feed is mostly Nulab site furniture.

Only two entries in this window carry actual release content, and both are monthly digests: chart groups gaining a start/end date bar with issue counts and status breakdown on hover, personal charts dropping the parent-subtask relationship, an Android 3.0.1 redesign, Markdown in iOS custom-field text areas, plus quarterly-scale Gantt charts for Premium and Platinum plans and child-issue status filtering. The rest of the window is navigation, support links and marketing copy scraped from nulab.com — including rows that belong to sibling products Cacoo and Nulab Pass rather than to Backlog.

What is Tability?

Tability is building the org graph its AI agents will need to act on.

Tability is an OKR and strategy platform that has spent 2026 turning a plan hierarchy into a queryable graph. The Strategy Map now organises by people as well as plans, the Dependencies Map traverses up to parent context and down through downstream work from any object, and a workspace-wide filtering layer with saved segments sits over goals and initiatives. Running alongside is an agent track: an AI Importer that reads OKR and KPI spreadsheets into reviewable proposals, and AI managers that can be assigned to a goal and must route decisions back through an approval flow.

Backlog vs Tability: editorial side-by-side

Backlog logo0.0

Backlog ships steady Gantt and chart refinements, but the feed is mostly Nulab site furniture.

◆ Current state

Only two entries in this window carry actual release content, and both are monthly digests: chart groups gaining a start/end date bar with issue counts and status breakdown on hover, personal charts dropping the parent-subtask relationship, an Android 3.0.1 redesign, Markdown in iOS custom-field text areas, plus quarterly-scale Gantt charts for Premium and Platinum plans and child-issue status filtering. The rest of the window is navigation, support links and marketing copy scraped from nulab.com — including rows that belong to sibling products Cacoo and Nulab Pass rather than to Backlog.

◆ Where it's heading

The real work is concentrated on planning views — Gantt scale, chart grouping, issue filtering — and on closing gaps between the web app and the mobile clients. Several changes are explicitly gated to Premium and Platinum plans, so view sophistication is being used as tier differentiation. Nothing here suggests a change of direction; it is a mature tracker refining how work is visualised.

◆ Prediction

Given the run of chart and Gantt scale work, the next planning-view change is likely another axis of aggregation or filtering rather than a new surface. The scraped entries make cadence unreliable, so any stronger call would not be grounded.

T7.5

Tability is building the org graph its AI agents will need to act on.

◆ Current state

Tability is an OKR and strategy platform that has spent 2026 turning a plan hierarchy into a queryable graph. The Strategy Map now organises by people as well as plans, the Dependencies Map traverses up to parent context and down through downstream work from any object, and a workspace-wide filtering layer with saved segments sits over goals and initiatives. Running alongside is an agent track: an AI Importer that reads OKR and KPI spreadsheets into reviewable proposals, and AI managers that can be assigned to a goal and must route decisions back through an approval flow.

◆ Where it's heading

The two tracks are converging, and the sequencing tells the story. Delegating goals to AI agents shipped first; the releases since have been building the structure those agents need to reason over — who reports to whom, what depends on what, which slice of a busy workspace a question is actually about. Overflow controls on large maps and a refreshed Initiatives view point at customers with enough plans and people for readability to become the constraint, which is a different buyer than the small-team OKR tool this category started as. Import friction is being attacked from the same direction: an AI-assisted path out of spreadsheets, with review gates before anything is created.

◆ Prediction

Expect the agent features to start consuming the graph the recent releases exposed — dependency-aware and reporting-line-aware agent actions rather than per-goal delegation — and the scheduled-prompt mechanism behind executive summaries to widen into other recurring outputs.
