Release overview — September 2026

The Curiosity Team

• 2026-09-28

September brought a new name and more ways to build inside the product: Curiosity Workspace is now Curiosity Studio, a workspace hosts its own front-end, and Sudo, the admin assistant, can take on much more of the work. Five releases this month.

Curiosity Studio, with a new look

• Every user-visible mention of "Curiosity Workspace" now reads Curiosity Studio, including the Windows installer, service name and Start Menu entries.
• The web app runs in the Curiosity theme by default, with the new logo, a redesigned sign-in screen and pixel-art glyphs for empty states.
• Curiosity Studio works on phones: the sidebar becomes its own page, and side panes and selectors open as bottom sheets.

Sudo does more of the work

• Attach files and paste images into a Sudo chat. He reads archives as folders and extracts document text on demand.
• An assistant can delegate to an agent in the background and keep the conversation going. Sudo ships with a built-in "Sudo Agent" for investigation.
• Nothing is applied unseen. Approval happens on the review screen, where you can edit Sudo's proposed code first. Proposals survive restarts, and a commit that would overwrite someone else's change is refused until it is merged with the new pull command.
• curio opens the same sandbox from your terminal: a file commander between the workspace and your disk, a console, and the edit, build, commit and approve loop, as a .NET tool or a download for Windows, Linux and macOS.

Front-end development inside the workspace

A workspace now hosts its front-end source as a git repository and compiles it on the server, with no .NET SDK needed in the image. The new Front-End admin category covers source, branches, per-commit builds and "Make live", and every compiled commit can be previewed at /commit-<hash>/. Sudo's frontend command reads, builds, previews and commits changes through the same review screen as everything else.

Documents, decks and artifacts in chat

• Assistants publish artifacts (an HTML page, or Markdown rendered to PDF) that open from a chip under the message, and a new Artifacts panel lists them.
• Build PowerPoint decks with 46 built-in slide design systems, and download a canvas document or deck as a Word or PowerPoint file.
• Markdown extraction for every supported document, with about 25 newly extracted formats, plus a local PaddleOCR-VL engine for scans.

Governance and access

• With administrator write protection, every administrator is treated as read-only. Unlocking needs a code the server writes to its storage folder and never sends over the network.
• Text indexes restricted to access groups keep one copy per group, which makes searches on large, heavily partitioned workspaces much cheaper.
• A Change History page shows every change to the workspace's code as a diff, and an Access Hierarchy page explores teams and their members.

For developers

• Sandbox AI tools give an agent a filesystem built from workspace data, so a model can answer with ls, grep, jq and python.
• StructuredAI answers choice, score and yes/no questions and re-ranks nodes with a local model or a configured LLM.
• AI tools can return files, connectors get a Dry Run that writes nothing, and queries gain TakeRandom(count) and WithTimeout(...).

The little things

• Pin chats, and an interrupted reply keeps what it had already produced.
• Chats keep streaming while their tab is in the background.
• LLM usage is broken down per user, and new Front-end Requests and Runtime Statistics pages show request timing and database counters.
• New CLI commands verify and export audit logs offline.
