What is Capacities?
Capacities ships API 2.0, pivoting from self-contained PKM toward a connected AI memory layer
Capacities is a structured personal knowledge management tool shipping at monthly cadence. In the past 4 months it has added AI Chat Connectors (connecting the space to ChatGPT, Claude, and Cursor), a developer-facing API 2.0, weblink reader and analysis, PDF annotations, AI image generation, and configurable AI model providers. The combination describes a product moving from self-contained PKM to a node in a broader AI-augmented knowledge graph.
What is KACE?
KACE extends its PHP2SHELL fix to the SDA deployment appliance, six days after disclosure.
KACE has now patched the critical PHP2SHELL vulnerabilities across both appliances: SMA 15.1 and 15.0 on October 23, and the SDA 9.3 deployment appliance on October 27. SMA also gained official support for Windows 11 26H2 agents and patches, following KACE Cloud's 26H2 support a few days earlier.

Capacities ships API 2.0, pivoting from self-contained PKM toward a connected AI memory layer
◆ Current state
Capacities is a structured personal knowledge management tool shipping at monthly cadence. In the past 4 months it has added AI Chat Connectors (connecting the space to ChatGPT, Claude, and Cursor), a developer-facing API 2.0, weblink reader and analysis, PDF annotations, AI image generation, and configurable AI model providers. The combination describes a product moving from self-contained PKM to a node in a broader AI-augmented knowledge graph.
◆ Where it's heading
The consistent direction is making Capacities connectable — first via AI chat integrations, then a proper developer API, and now deeper object types and AI media generation. The new Pro+/Believer+ pricing add-ons indicate AI usage is growing enough to require metered capacity. The platform is accumulating capability surface faster than a traditional note-taking tool and faster than comparable PKM competitors.
◆ Prediction
The most likely next move is deeper API-to-AI-connector integration, letting third-party agents create and modify Capacities objects programmatically — the existing connector work is the precondition for functioning as an AI memory layer rather than just a note store.
KACE
5.0COLLAB
KACE extends its PHP2SHELL fix to the SDA deployment appliance, six days after disclosure.
◆ Current state
KACE has now patched the critical PHP2SHELL vulnerabilities across both appliances: SMA 15.1 and 15.0 on October 23, and the SDA 9.3 deployment appliance on October 27. SMA also gained official support for Windows 11 26H2 agents and patches, following KACE Cloud's 26H2 support a few days earlier.
◆ Where it's heading
The changelog is dominated by security response and OS-version coverage, with both SMA branches patched in lockstep. Feature work is limited to agent reliability fixes. KACE behaves like a maintained endpoint-management line rather than one being redirected.
◆ Prediction
Expect November Patch Tuesday content and further cumulative patches on both SMA branches. The entries don't point to new feature work.
