Short answer
An auto clicker repeats a mouse click for you. Choose the mouse button, decide where the click should land, set a comfortable interval and test one short run. Keep the target visible, stay at the computer and know the stop keys before you begin.
Before you start
Use harmless sample data. Do not test a purchase, account change, delete command or anything difficult to undo. The app sends input to the active Windows desktop; it cannot reliably control a minimized, background or protected window.
Set up your first repeated click
1. Open the Mouse tool
Start Osenpa Auto Clicker and open Mouse. A mouse action needs three basic answers: which button, where to click and how long to wait between clicks. You should see controls for the button, position, interval and repeat count.
2. Choose the mouse button
Use Left for a normal click unless the task clearly needs Right, Middle, Mouse 4 or Mouse 5. The last two names refer to the side buttons found on some mice. You should see Left selected.
3. Choose the position
Current position follows the pointer location used when the action runs. Fixed position uses saved X and Y screen coordinates. Choose Fixed position. Pick the point from the harmless target you prepared. You should see its X and Y numbers in the Mouse tool. Keep the target window in the same place.
4. Set a slow interval
The interval is the pause between actions. Begin slowly enough to watch every click. You should have enough time to see the target react before the next action.
5. Set a small repeat count
Choose 1 for the first test. Do not select continuous repetition until a limited run works correctly.
6. Run once before saving a workflow
Use Run Once to test the current mouse settings without building a long document. Watch the pointer, the target and the result. You should see exactly one click on the harmless target. Stop immediately if focus moves to another window.
7. Add the action as a step
When the single action is correct, select Add Step. You should see one new Mouse step in Steps. You can name, edit, duplicate, move, disable or delete it later. Add a delay or visible condition before repeating a step whose completion time changes between runs.
Checkpoint: one controlled click
Stop before adding a loop. Confirm that one run uses the intended button and position, reaches the expected harmless result and can be interrupted with F12.
Know the stop controls
F7 is the default Run and Stop key, but it can be changed in Settings. F12 is permanently reserved for Emergency Stop. F12 cancels active automation, recording, tests and scheduled work, then releases any key or mouse button the app is holding. Test Emergency Stop once with a harmless two-step workflow so you know what it feels like before an important task.
What happens on the desktopInput, permissions and scheduling boundaries.
- Only one task that produces keyboard or mouse input can own input at a time.
- Windows can block input to an elevated application unless Osenpa Auto Clicker is also elevated.
- A schedule can start once at a local time or repeat at an interval up to seven days, but the app must remain open.
- Secure Desktop, minimized windows and protected screen content are outside the reliable visible-input workflow.
Use Input Variation when exact repetition is not useful
Input Variation is off by default. Turn it on only when repeated runs need small timing changes or small position changes for regular click and drag steps.
Image Detection keeps matched coordinates exact, and a one-pixel color target stays fixed. Input Variation does not change OCR, sound matching, target choice, timeouts or safety checks. It cannot predict whether a website will allow or detect automation.
Common first-run mistakes
- Starting with unlimited repetition
- Testing on a destructive or paid action
- Moving the target window after saving fixed coordinates
- Expecting clicks to reach a minimized or background target
Safe setup checks
- The correct button and position are selected.
- The interval is slow enough to observe.
- One limited run reaches the expected result.
- F12 stops a harmless test immediately.
- Re-test after changing focus, permissions, display layout or the target app.

Start with one repeated click, then add editable steps, visible conditions, loops or scheduling only when the task needs them.
