Air's asset library grew an agent, and the agent is learning to keep what it does.
Canvas has become the centre of the product. In the last three weeks it gained an agent that edits existing video rather than only generating new clips, two additional video models, the ability to save any completed workflow as a reusable skill, @ mentions that pull in board assets alongside Brand Kit colours, fonts and logos, and now in-image text translation across 33 languages. The library side kept moving too, with manual person tagging where facial recognition falls short, current-version share links, frame-level timeline zoom, and a batch of video features covering burned-in captions, transcript editing and sub-clipping.
HeroUI grew a component catalogue, then wired it into a chat editor.
The feed runs from March 2024 to July 2025 and stops there, so nothing here describes the last twelve months. Across that stretch the pattern is consistent: batches of components counted in the headline, a page reorganisation once the catalogue outgrew a flat list, framework currency with React 19 and Next.js 15 and later TailwindCSS v4, and a rebrand from NextUI Pro to HeroUI Pro in January 2025. The one change of kind is instant editing of any component inside HeroUI Chat.

Air is converting a digital asset manager into a place where assets are produced and adapted, not just stored and approved. The skills feature is the pivot point: it turns one-off agent instructions into named, repeatable operations, which is how a creative team's conventions become part of the tool. Brand Kit entering the @ mention namespace points the same way — the agent is being given the brand's own vocabulary as addressable material, so generated work starts from house colours and logos rather than a generic prompt.
Expect skills to gain sharing or workspace-level scope, since a saved workflow is far more valuable to a team than to the person who recorded it. The translation and captioning work together suggests localisation is being assembled as a workflow rather than left as isolated features.

The archived arc moves from selling a catalogue to selling a workflow — a component is worth more if it can be customised where it is chosen rather than copied into an editor first. Framework support releases show the other constant: a paid component library lives or dies on how quickly it tracks the framework underneath it. What has happened since July 2025 is not visible from this source.
No recent entries support a confident prediction; the actionable finding is that this feed has been silent for roughly a year and needs re-pointing before HeroUI's direction can be read.
