Text provenance checker

See how text reads. Know what that can't prove.

Sift is a fast, private way to look at a piece of writing. It is straight with you about the difference between a texture profile and a proven verdict - and about when no real detector is connected at all.

Analysis runs on your device. Text is never sent anywhere unless you also run a connected detector below. Ctrl/Cmd+Enter runs the local analysis.

The three things to remember

01
No detector proves authorship. Any number you see is a probability-like estimate with real false positives and negatives.
02
Here, with no detector connected, the local readout is an experimental texture profile - clearly labeled, never presented as validated AI detection.
03
Your text stays on your device unless you run a connected detector, and this site never stores what you paste.
