# Improved 3D editor comments, now with AI

Comments in the 3D editor have been rebuilt: a comments panel, real resolve, unread markers and previews on the canvas. Spline's AI agent can now work from comments too. Ask AI on a thread and it makes the change, looks from the commenter's view and replies with what it did.

## Changes

**3D editor**

- **Comments panel** \- Comment mode opens a panel listing every thread, with participants, reply count and time. Filter by this scene or all scenes, and show resolved threads. Opening a thread switches to its scene and moves the camera to the commenter's view.
- **Resolve and reopen** \- Resolving a thread keeps it instead of deleting it, and you can reopen it later.
- **Unread markers** \- Red dots on pins and in the panel show threads with new replies. Mark threads read or unread.
- **Pin previews** \- Hover a pin to see its first comment and profile photos. Right-click a pin to resolve it, mark it unread or Ask AI.
- **Hide comments** \- Shift+C hides and shows all comments.

**AI & agents**

- **Ask AI on a comment** \- Send a thread to Spline's AI agent. It makes the change, checks it from the commenter's camera and replies on the thread. It resolves threads only when you ask.
- **Comments over MCP** \- Claude, ChatGPT and other MCP clients can read, reply to and resolve comments.

**Fixes**

- Comments no longer show over the running scene in the Preview tab.
- Escape closes the open thread.
