Keep your voice. Find the flags.
Paste a draft or drop in an image. See the signals, read the reasons, then decide what to change.
01 / THE CHECK
Your notes will appear here after a check.
A score is evidence, not proof of how something was made.
A flag needs a reason.
Writing checks mark phrases and explain the pattern behind each one. Image checks look for file evidence and, when configured, visual clues.
How it works ↗What gets marked
Stock phrases. Vague claims. Filler. Repeated sentence shapes. Each mark comes with a reason and a suggested edit.

Before you check
Does a high score prove AI use?
No. A score reports signals. Human work can trigger them, and AI-made work can miss them. Read the reasons and check the context.
What works in Basic mode?
Writing rules and image metadata checks. Rewrites and visual analysis need an external service. An image without generation evidence has no probability estimate in Basic mode.
Do you keep my draft or image?
No original text, images or rewrites are stored. We retain hashes, scores and a safe result record. Optional analysis services receive content needed for their checks.
When does my allowance reset?
At midnight UTC. Text and image checks count toward the same daily allowance. Invalid input does not use a check. A delivered result counts even if an optional engine fails.
