New tools record how authors write to prove they wrote the book

Hachette Book Group canceled the US publication of the novel Shy Girl in March 2026. Claims online said that AI wrote it. Pangram, a tool that detects AI text, said 78 percent of the text was AI made. It is not always right. The author denies the claim, and new tools record how authors write, to give proof.

How the tools work

These five tools record how an author writes:

• Workings
• Blindproof
• Wintertext
• Human Ink
• ObraVera

Some tools encrypt the text or mark typing rhythms with unique codes. The record can show if the work is human or AI assisted.

The proof

The source gives no test results for the tools. Mia Ballard, the author of Shy Girl, denies the claim. Ballard says an editor made AI assisted changes to an earlier self published version. Ballard pursues legal steps.

What is not known

Andrea Bartz, a novelist, says no agreed standard exists to prove human authorship. Bartz says authors find it hard to defend themselves. The source does not say if publishers accept these records.

Insight: Weak detectors move the proof to the author

A study in October 2026 found that AI checkers of conference papers are weak when someone tries to fool them. Pangram is also not always right. This reads as a move of proof to the author, and firms that hold the records get more control. Look for a publisher that names one accepted record.
