The name

The copyboy carried every story by hand from writer to desk. Copyboy carries the evidence: what’s backed, what’s missing, and what’s unclear.

How it works

Open a pitch.

Click Copyboy on any pitch or brief in Gmail or Outlook.

Every claim, checked.

Each claim is marked Backed (a filing, dataset, or paper supports it), Missing proof (nothing we can find supports it), or Unclear (sources disagree, or it can’t be checked).

One proof score.

The email gets an overall score out of 100, so you know where to start.

Copyboy also gives a light signal on whether a message may be AI-written. It’s an early hint, not a finding, and it will improve over time.
