Hide a line in a photo. Tilt the glass to read it.

You already have the picture. The sentence only shows when the glass leans the way you chose.

The picture stays on this device. A dusk card works if you have no photo yet.

Head-on it is only a photo. Tilt to the angle you set — the line comes up.

Drop a photo, then write the hidden line.

When to use this

A photo on the screen, and nothing else — until you lean the phone. The hidden line is for the person who knows which way to tilt.

This tool runs in your browser. The words, audio, and photos are not uploaded. You do not need an account.

How to use it

  1. 1

    Drop a photo, or start from a dusk card. Type the hidden line.

  2. 2

    Choose a direction and an angle. Head-on it should stay a photo.

  3. 3

    Open present on the phone, or download the glance HTML. Tilt until the words come up. PNG is the quiet still.

Examples

A wallpaper

Set the glance as a full-screen page. Anyone else sees the photo. You tilt left, and the vow is there.

A date only two people keep

The picture is a street at night. Lean it away from you and the date writes itself.

A name on a portrait

Keep the strength low. The face stays a face until the glass moves.

Limits

  • Work stays in this browser. Nothing is uploaded.
  • Exports are PNG and SVG. They are not a certificate, a medical record, or a legal document.
  • Very long text can crowd a square print. Short phrases read as jewelry; paragraphs read as a poster.
  • The glance HTML uses this phone's motion sensors. A saved PNG has a faint optical split that is stronger on LCD than on OLED. It is not encryption: anyone who opens the HTML can read the line.

FAQ

Do I need an account?
No. These tools finish in the browser.
Is my text or audio uploaded?
No. The file and the words stay on this device.
Is it free?
Yes. Momentmark does not add a watermark.
Do I just tilt a PNG?
On some LCD screens the encoded PNG itself shifts. On most phones, open the glance HTML or use Present — the photo fills the glass, and tilting to your angle brings the words up.
Is the photo uploaded?
No. The file never leaves this tab. The downloaded HTML carries the picture inside it, on your device.
