From a flag to an edit.
A check gives you a place to look, with a reason to look there.
1. Put the work on the desk.
Paste at least 40 words or upload a JPEG, PNG or WebP. The checker validates the input before using a check.
2. Read the notes.
Local writing rules find recurring patterns. File metadata can contain generation tags. Optional external analysis adds writing, statistical and visual signals. Results name the engines that ran.
3. Make the call.
Use phrase suggestions or request a rewrite when writing analysis is available. Compare the edit with your source. Image notes suggest areas to inspect; they do not edit your file.
