Labs — concept in validation

Your voice, unmistakably human.

Sigil isn't another flawed AI detector. It's a style authenticator that analyzes your manuscript for passages that *readers* might misperceive as AI-generated. Get actionable feedback to refine your work without sacrificing your unique voice, so you can publish with total confidence.

A waitlist signup is a vote. No spam — we'll only email you about Sigil.

The problem

Sound familiar?

1

You second-guess your natural writing style, worried a reader will falsely accuse you of using AI.

2

A single bad-faith accusation could damage your reputation, impact sales, or jeopardize a future publishing deal.

3

Existing AI detectors are unreliable and force you to change your authentic voice just to pass their tests.
