Most of this release needs a quick reinstall. These fixes live in the part of Sidekick that is installed on your computer, which can’t update itself. Download the latest version from the install page and run it; your settings and your Adobe Exchange plugin stay as they are.
No More Waiting on a Stuck Sidekick
Now and then Sidekick could stop responding mid-session: your assistant waited, every InDesign command timed out, and the only way out was to quit and restart the assistant. Sidekick now notices when that happens and recovers by itself, so you can carry on where you were.
An Honest Health Check
When you used Claude with Cowork, asking “sidekick health” could report that InDesign was not connected, even though every command worked fine. That made a working setup look broken, often right at the end of installing it. The health check now reports what actually happens: if your assistant can reach InDesign, it says so.
Your Computer Only
Sidekick now accepts InDesign commands only from the computer it runs on. Other machines on the same network can’t reach it, whatever the network or firewall settings.
Smoother Starts After an Update
On the first start after a new release, Sidekick could fail to start in Claude, until you restarted it. This happened when Claude started Sidekick twice at the same moment, for chat and for Cowork. Both now finish the update cleanly.
Settings That Reach Every Assistant on Windows
On Windows, asking Claude Desktop to “disable Sidekick telemetry” didn’t reach Sidekick when it ran in another assistant, such as Claude Code, Cursor or Codex, and the other way round. A choice you make in one assistant now applies to all of them.
A Guide for Every Assistant
The install page now has a short guide for each AI assistant: Claude, ChatGPT, Claude Code, Codex, Cursor, Devin Desktop (formerly Windsurf) and OpenCode, with the simplest route first. Each guide ends by asking your assistant a question only InDesign can answer, such as how many pages your document has, so you know right away that everything works. There’s also a new help article on getting a receipt or invoice for your subscription.
