+## Debounce Workflows to Prevent Wasted Work
+
+Debouncing delays workflow execution until some time has passed since the last trigger. Useful for user input processing.
+
+**Incorrect (processing every input):**
+
+```python
+@DBOS.workflow()
+def process_input(user_input):
+    # Expensive processing
+    analyze(user_input)
+
+@app.post("/input")
+def on_input(user_id: str, input: str):
+    # Every keystroke triggers processing!
+    DBOS.start_workflow(process_input, input)
+```
+
+**Correct (debounced processing):**
+
+```python
+from dbos import Debouncer
+
+@DBOS.workflow()
+def process_input(user_input):
+    analyze(user_input)
+
+# Create a debouncer for the workflow
+debouncer = Debouncer.create(process_input)
+
+@app.post("/input")
+def on_input(user_id: str, input: str):
+    # Wait 5 seconds after last input before processing
+    debounce_key = user_id  # Debounce per user
+    debounce_period = 5.0   # Seconds
+    handle = debouncer.debounce(debounce_key, debounce_period, input)
+    return {"workflow_id": handle.get_workflow_id()}
+```
+
+Debouncer with timeout (max wait time):
+
+```python
+# Process after 5s idle OR 60s max wait
+debouncer = Debouncer.create(process_input, debounce_timeout_sec=60)
+
+def on_input(user_id: str, input: str):
+    debouncer.debounce(user_id, 5.0, input)
+```
+
+When workflow executes, it uses the **last** inputs passed to `debounce`.
