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 first. Do not test on a purchase button, account setting, delete command or anything that is difficult to undo. Osenpa Auto Clicker sends regular input to the active Windows desktop. It is not a background service and cannot safely control a minimized 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.
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.
3. Choose the position
Current position follows the pointer location used when the action runs. Fixed position uses saved X and Y screen coordinates. Pick the fixed point from the harmless target you prepared, then confirm that the window has not moved.
4. Set an interval and repeat count
The interval is the pause between actions. Begin slowly enough to watch every click. Use a small repeat count for the first test. Continuous repetition should come only after a limited run works correctly.
5. 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. Stop immediately if focus moves to another window.
6. Add the action as a step
When the single action is correct, add it to 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 when repeated runs should not use exactly the same timing or, for regular click and drag steps, exactly the same position. It adds only the small changes you choose.
Image Detection keeps the 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 can make input less uniform, but 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.

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