+## Streaming previews
+
+Matrix reply streaming is opt-in.
+
+Set `channels.matrix.streaming` to `"partial"` when you want OpenClaw to send a single draft reply,
+edit that draft in place while the model is generating text, and then finalize it when the reply is
+done:
+
+```json5
+{
+  channels: {
+    matrix: {
+      streaming: "partial",
+    },
+  },
+}
+```
+
+- `streaming: "off"` is the default. OpenClaw waits for the final reply and sends it once.
+- `streaming: "partial"` creates one editable preview message instead of sending multiple partial messages.
+- If the preview no longer fits in one Matrix event, OpenClaw stops preview streaming and falls back to normal final delivery.
+- Media replies still send attachments normally. If a stale preview can no longer be reused safely, OpenClaw redacts it before sending the final media reply.
+- Preview edits cost extra Matrix API calls. Leave streaming off if you want the most conservative rate-limit behavior.
