AI Vibe Check

What gives writing its AI vibes?

Explore an AI vibe score and the writing patterns behind it. It measures style signals, not proof of authorship.

  • Pasted text stays in the browser
  • URL mode sends the URL to Astra Lab, retrieves a public page, and shows its text for preview before analysis
  • See highlighted clues and counter-signals
Open AI Vibe Check

English prose only. The language check is approximate, and human writing can score high.

A style check

Formulaic phrasing and repeated structure raised this example score. Concrete details can lower it.

A lab for everyday friction.

Astra Lab is an independent experiment in building useful software with AI. We start with a specific problem, make a small tool, and learn whether it helps.

These tools are available here while we learn what people actually use.
