One cut,
checked on ten screens first.

Let it run once on its own.

Drop in a cut → turn on the safe area → mark one note → export the report. What plays below is the real interface, auto-played — nothing here is a drawn mock-up.

01　Drop the cut in

Three steps, ten platforms, one pass.

No need to memorise each platform's rules. What they look like and what they cover is laid straight onto the frame.

Everything you need.
Not one byte you should not send.

The client installs nothing.
Four characters and they're watching.

It exists for one very concrete scene: the cut goes over, and the client types “around the third second, that bit” in WeChat. Both sides go back and forth and still fail to land on the same frame.

Now a four-character code opens a player in their phone browser: they can scrub, draw a box, write a note, and it stops on the exact frame. When they hit “notes done, notify sender”, a sound and a notification reach you at once.

From preview to report, no other tools.

One cut goes in; check, notes, version compare and report all finish in the same window.

01

Check

Ten platforms' interfaces and overlaps in one pass, with a verdict under each screen: intact, edges only, or cropped by how much.

02

Notes

Mark the frame that is wrong, on that frame. Pen, rectangle, circle, arrow, subtitle band — notes stay attached to the asset and survive version switches.

03

Version compare

Several versions of one cut side by side, one timeline, one action. When the client changes a version, no folder digging.

04

Report

Current frame + platform interface + safe area + notes into one PNG. Title, memo, client name are editable and paste straight into WeChat or email.

The web is fast. The client goes deep.

The web version adds the crosshair and the vertical subtitle band (portrait cuts get covered on the sides); the client adds the circle.

Why unreleased footage is safe here.

Checking is, at heart, decoding one frame and measuring where the pixels land. That needs no network and hands the material to nobody. So it was built as fully local from the start: frame analysis runs on your machine, and the result stays on your machine.

Online notes are the only feature that leaves the machine, and that is a trade we made deliberately: one compressed proxy goes out (80MB by default, resolution untouched, bitrate lowered only), deleted about three hours after the session ends. The original never leaves your machine, at any point.
