+title: The HassGetState intent
+---
+
+We've added a new [built-in intent](/docs/intent_builtin/): `HassGetState`
+
+This intent will enable users to ask questions to [Assist](https://www.home-assistant.io/docs/assist) once we've added translations to the [intents repository](https://github.com/home-assistant/intents/).
+You can try it out now by adding [custom sentences](https://www.home-assistant.io/docs/assist/custom_sentences):
+
+```yaml
+# Example <config>/custom_sentences/en/get_state.yaml
+
+language: en
+intents:
+  HassGetState:
+    data:
+      - sentences:
+          - what is <name> [in <area>]
+          - is <name> {state} [in <area>]
+
+responses:
+  intents:
+    HassGetState:
+      default: "{{ slots.name }} is {{ state.state_with_unit }}"
+
+lists:
+  state:
+    values:
+      - "on"
+      - "off"
+      - open
+      - closed
+      - locked
+      - unlocked
+      - wet
+      - dry
+```
+
+With these sentences, you can now ask Assist things like "what is the outside temperature?", "is the front door locked?", or "is the floor in the basement wet?"
+This relies on having entity names (or aliases) set up just right, of course. For example, a sensor named "outside temperature" and a binary moisture sensor named "floor" in the "basement" area.
+
+As we add translations, more types of questions will be possible such as "which lights are in the living room?" and "are any doors unlocked?"
