Verify the statements, numbers, and quotes in your draft against sources — and catch the confident mistakes AI leaves behind.

“The report was cited over 10,000 times in its first month.”
No source supports this figure. The closest citation count is in the low hundreds — worth checking before you publish.
Catch
Invented figures, misattributed quotes, dates that are close but off — the reasoning is laid out so you can fix it, not just a red flag.
I run my drafts through it before I send anything. It flags the lines that read as machine-written, so I can be sure the writing is actually mine — a quick gut-check that saves a lot of second-guessing.
I can see exactly what to fix without rereading everything. Two minutes instead of an evening of second-guessing my own paragraphs.
This is the check I do before I send anything out. It has saved me from shipping copy that reads like a template more than once.
Beats trying to prove a paragraph was mine after the fact. Now I check first and keep the report.
The humanizer rewrote the flagged lines without mangling the terminology, which nothing else I tried managed to do.
It reviews the checkable claims in your writing — statements, numbers, dates, and quotes — and flags the ones that don't hold up against sources, so you can fix them before you publish.
AI writes confidently even when it's wrong — invented figures, misattributed quotes, dates that are close but off. The fact checker catches those before a reader does.
Your text is used to run the check and nothing else. It's never published and never sold.
Run your draft through the fact checker and see which claims hold up.
