Add an Intruder to a House Photo

How it works

1. 1

   Upload your photo

   Upload a photo of your hallway, bedroom, living room, backyard, or the exterior of your house. Low-light or nighttime photos tend to produce the eeriest results — the less clearly the figure needs to be defined, the more convincing the prank. A partially lit corridor is ideal.

   Expect: The upload takes under 5 seconds. Photos with some depth or distance — like a hallway or a view down a staircase — give the intruder a natural place to stand.

   Describe the intruder

   Type exactly where you want the figure and how they should appear. Be specific about position (end of the hallway, standing in the doorway, outside the window), visibility (barely visible shadow vs. clearly outlined silhouette), and posture (standing still, crouching, facing away). The more specific, the more realistic.

   Tip: Partially visible figures — behind a door, around a corner, or at the edge of shadow — are far more unsettling and convincing than a fully visible person. Describe them as almost hidden rather than obvious.

   Copy one of these to get started:

   Hallway figure — classic horror Add a dark shadowy human figure standing at the far end of the hallway, barely visible in the dim light. The figure is tall, still, and facing toward the camera. Just visible enough to be unmistakably a person.

   Person outside the window at night Add a dark human silhouette standing outside the window in the darkness, partially visible through the glass. The figure is close to the window and appears to be looking in. Only visible because of faint exterior lighting.

   Figure in the doorway Add a dark human figure standing in the open doorway of the room, leaning slightly against the door frame. The figure is in shadow, facing into the room, clearly watching.

   Crouching behind the bed Add a dark crouching human figure barely visible at the side of the bed, hunkered down and hiding in the shadows between the bed and the wall. Almost not visible but clearly a person.

   Reflection in the dark TV screen Add a shadowy human figure reflected in the dark TV screen or mirror in the background of the room — as if someone is standing behind the camera but visible in the reflection.

   Standing on the stairs Add a dark human figure standing halfway up the staircase, gripping the railing, looking down. Partially in shadow, clearly an adult-sized person. Not moving, just watching.

   Figure in the backyard Add a dark human silhouette standing in the backyard near the fence, facing the house. Only the outline is visible against the fence, completely still. Late-night lighting.

   Download the edited photo and text it to your partner, roommate, or family member who's home alone. "Can you check if the door is locked" works well as a follow-up. Screenshot everything that follows.
