+## Debounce Workflows to Prevent Wasted Work
+
+Use `dbos.NewDebouncer` to delay workflow execution until some time has passed since the last trigger. This prevents wasted work when a workflow is triggered multiple times in quick succession.
+
+**Incorrect (executing on every trigger):**
+
+```go
+// Every keystroke triggers a new workflow - wasteful!
+func onInputChange(ctx dbos.DBOSContext, userInput string) {
+	dbos.RunWorkflow(ctx, processInput, userInput)
+}
+```
+
+**Correct (using Debouncer):**
+
+```go
+// Create debouncer before Launch()
+debouncer := dbos.NewDebouncer(ctx, processInput,
+	dbos.WithDebouncerTimeout(120*time.Second), // Max wait: 2 minutes
+)
+
+func onInputChange(ctx dbos.DBOSContext, userID, userInput string) error {
+	// Delays execution by 60 seconds from the last call
+	// Uses the LAST set of inputs when finally executing
+	_, err := debouncer.Debounce(ctx, userID, 60*time.Second, userInput)
+	return err
+}
+```
+
+Key behaviors:
+- First argument to `Debounce` is the debounce key, grouping executions together (e.g., per user)
+- Second argument is the delay duration from the last call
+- `WithDebouncerTimeout` sets a max wait time since the first trigger
+- When the workflow finally executes, it uses the **last** set of inputs
+- After execution begins, the next `Debounce` call starts a new cycle
+- Debouncers must be created **before** `Launch()`
+
+Type signature: `Debouncer[P any, R any]` — the type parameters match the target workflow.
