FAQ

Common questions

Is Naturable free?

Yes. Checking, highlighting, and rule-based quick fixes are completely free and unlimited, with no sign-up. Pro pricing is being tested and is not yet open.

Does my text get uploaded?

No. The current free checker runs entirely in your browser. Planned Pro processing is still being tested and is not yet open.

Does this help me bypass AI detectors?

Naturable is a writing-quality tool that removes robotic phrasing so your writing reads naturally. It is not sold as a way to beat any specific detector, and no tool can reliably guarantee that.

What exactly is an "AI tell"?

A recurring pattern typical of AI writing: em-dash overuse, filler phrases, clichés like "a testament to", the "rule of three", chatbot leftovers, and uniform sentence rhythm. See the full list.
